Random answer day (1)

Posted on September 9, 2021 by pj

Maybe it’s the first day of the regular NFL season or the phase of the moon. Here’s a recap of a few questions that came into the forums.

How are arranger/synth preset voices stored? First, one may ask, “How is a preset represented?” Typically, a preset voice consists of waveforms (AKA “samples”) and voice (meta-)data. The voice data control how the sample-playback engine applies filtering, amplitude envelope, modulation and so forth. The waveforms, of course, provide the basic digital audio data.

There is such a broad range of arranger/synth products at different price points, that the amount of storage and the kind of storage varies quite a lot.

The lowest of the low in the Yamaha range: PSS-A50, -E30, -F30, PSR-F51. Presets are stored on a 2MByte serial flash ROM and are loaded into the processor (SWLL) at start-up. The 2MBytes include code, too! Tone generation is integrated into the SWLL. Insanely small, and very low cost.

The highest of the high in the Yamaha range: Genos. Factory presets are stored in four 1GByte ONFI NAND flash devices. Expansion memory consists of two 1GByte ONFI NAND flash devices. Wave memory connects directly to external tone generators (SWP70).

I’ve looked at the diagrams for Genos and I’m not sure about the size and function of those memory units, especially Genos USER memory and expansion memory.

Yamaha confuses people when they speak of “user memory,” “internal memory,” etc. They are usually referring to logical, user visible storage.

When getting down to the hardware level, there are many different physical memory units. since we’re not discussing fairy dust or magic, the logical storage must be assigned to one or more physical memory units. And, of course, the physical memory units themselves may be composed of multiple integrated circuits. The other dimension is “what communicates to what.” Memory is passive and needs a processor to initiate reads and writes and to do something with all that data. At the physical level, a memory unit essentially belongs to a single processing unit (host computer, tone generator) and directly communicate with it.

Sometimes I think of the SWP70 as a parallel processor just like a GPU. The CPU/SWP70 is not exactly analogous to host CPU plus GPU, however. Graphics memory is shared between CPU and GPU. The SWP70 does not share its waveform memory with anybody — it’s dedicated to the tone generator. That’s why installing an expansion pack (voice library) is kind of slow and technically complicated, and why a Genos reboot is required.

Staying with Genos, Genos has two SWP70 tone generators: one handles factory presets and the other handles user expansion voices. The factory SWP70 has 4GBytes of flash memory while the expansion flash memory has 1GB of flash memory. That’s physical memory. Yamaha boosted the effective capacity to 3GB expansion through compression.

The SWP70s also have DSP RAM. As a user, you never know about this memory. It’s scratchpad memory for DSP effects. Physically, the DSP RAM is completely separate and independent from the waveform memory, and communicates with only its parent SWP70.

The host CPU has two kinds of memory (as determined by its bus interfaces): 1GB of working RAM on the CPU memory bus (EMIF) and two embedded eMMC memory devices that act like solid state storage drives (MMC0 and MMC1). As far as a user is concerned, the user never sees the 4GB eMMC drive (MMC0) just like you don’t see the DSP RAM; it’s hidden. The MMC0 drive contains the Linux operating system kernel and the root file system.

The user sees only part of the second 64GB eMMC drive (MMC1). The user sees the logical storage which Yamaha calls “Internal memory” or “USER drive.” What’s in the remaining 6GB? I don’t know — Yamaha haven’t left any clues.

What about Montage and its 5.67GByte waveform memory? 5.67GB is the capacity when the waveforms (samples) are compressed. Again, this is logical storage capacity.

Montage has two SWP70s. One SWP70 is dedicated to FM-X and it does not have waveform memory. The second SWP70 handles AWM2 synthesis (sample playback) and has waveform memory connected to it. The waveform memory consists of four 1GByte devices totaling 4GBytes. Thanks to Yamaha’s proprietary compression, Montage stores 5.67GBytes-worth of data in the physical waveform memory. The remaining space, 1.75GB physical, is available for user samples.

How does sample capacity relate to price? It doesn’t. Component cost is outweighed by manufacturing costs, software development cost and sound design cost.

If the memory components are so cheap, why isn’t there more waveform memory? If there was more, then you wouldn’t buy the Mark II model, would you? 🙂

I understand that E30/F30 do NOT offer velocity sensitivity. My question is about the internals. Is it confirmed that it’s a keybed with two switches per key, that just aren’t supported in software?

Yes, you need to be careful here. There are hardware model differences: E30 and F30 are not velocity sensitive. A50 is velocity sensitive.

There are two different keybed printed circuit boards (PCB). Yamaha part number VAY27800 for F30/E30 and VAY28500 for A50. The A50 PCB has the necessary diodes installed for velocity sense. The F30/E30 PCB does not have the diodes. Further, the A50 board has a 12-pin connector while the F30/E30 board has an 11-pin connector — perhaps to avoid assembly mistakes.

Is velocity sense worth the extra bucks? There may be other differences, too, but these differences are plainly visible.

And the usual caution/disclaimer — kiss the warranty good-bye! For the money, the PSS should be good mod-fodder. Korg probably sold a mess o’monotron that way.

Free DJX-II styles: Version 2

Posted on July 2, 2021 by pj

I’m happy to announce version 2 of my DJX-II styles for Yamaha Genos, Tyros and PSR arrangers.

These DJ styles are converted from the original Yamaha DJX-II patterns. If you would like to know more about the conversion process, please see: Mining the Yamaha DJX-II.

These are DJ styles, so they only respond to changes in the root note. The chord progressions are cooked into the patterns (just like intros and endings in regular PSR styles). I tried to find the best mapping from DJX-II patterns to style sections. Therefore, some of the DJXII styles have auto-fill, some do not. Longer “fill” patterns are assigned to the intro and ending sections which can play more than one measure.

Feel free to edit, rearrange and customize the styles in order to make them your own. I recommend Jørgen Sørensen’s excellent tools. Jørgen’s site also has documentation and tutorials about styles and style creation to help you along. Please check it out and support his work!

Click on this link to download the ZIP file.

Version 2 includes all of the files in the first collection. Version 2 adds Drum ‘n’ Bass, Disco, House and Trip Hop styles. The ZIP file includes a README.TXT file which should help you get started with the styles. I have also included PDF notation files for people who read music and want to know about the chord progressions, bass lines, and so forth.

Enjoy! The DJX-II style collection is free.

Arpeggio to style conversion

Posted on April 14, 2021 by pj

Let’s get one out of the vault… 🙂

The Motif XS/XF (MOX/MOXF) and Montage (MODX) arpeggios and performances are a great source of inspiration. Unlike Yamaha’s arranger series, the built-in phrase library is rich in urban and chill patterns. For some odd reason, one of the classic XS/MOX performances — “Dresden At Night” — never made the leap to Motif XF. And, it’s missing from Montage/MODX, too.

A PSR Tutorial forum member sought help resurrecting Dresden At Night, albeit a recreation for the PSR-SX700 arranger. I thought I would help out since I wrote a series of articles about MOX performance to style conversion:

The end result of that work is a small collection of PSR (Tyros, Genos) styles based on MOX (Motif XS) performances.

If you would like to try Dresden At Night or experiment with a conversion of your own, download the free ZIP file.

MOX performances have four parts (voices). Each part has up to six musical phrases (arpeggios) associated with it. Six front-panel buttons select the currently playing set of arpeggios, i.e., button one selects the first arpeggio for each set and so forth. To get the basic MIDI data, I played each arpeggio (group) for four measures while recording in MOX performance quick record mode. I wrote out the MIDI data as a Standard MIDI File (SMF), transfered the SMF to PC, and imported the SMF into a DAW (Sonar).

Dresden At Night is a downtempo (91 BPM), urban-ish chill performance. It has four parts:

Part# Voice    Name              NoteLo NoteHi VelLo VelHi Level Pan
----- -------- ----------------  ------ ------ ----- ----- ----- ---
  1   PRE8:070 8Z Heavy Hearts     C-2    G8     1    127    81   C
  2   PRE3:053 Dark Bass           C-2    G8     1    127    51   C
  3   PRE7:110 Ibiza Groove        C-2    G8     1    127   127   C
  4   PRE5:121 Smooth BPF Sweep    C-2    G8     1    127    73   C

The first part is the rhythm voice and the second part is the bass voice. As we’ll see below, arpegiation is turned for these two parts. The third and fourth voices are a play-along pad layer and arpeggiation is disabled. Thus, the rhythm and bass parts provide a looped backing while the pad voices provide an atmospheric you-steer-it, right hand part.

Here are the arpeggio assignments:

Arp#1 Tempo:91              Arp#2 
-----                       -----

  4   MA_Down Oct2            4   Off                  OFF

The Arpeggiator is turned ON for Parts 1 and 2 only.

A big factor is the “8Z Heavy Hearts” drum kit. The “8Z” in its name means “eight zone”. Eight zone (8Z) voices are a Motif innovation beginning with the XS (MOX) family. If you would like more information, check out these earlier posts about eight zone voices:

8Z voices aren’t drum kits. They are implemented as synth voices and are just a clever way of using the eight elements which make up a voice. The eight zones (8Z) are divided across specific note ranges. 8Z Heavy Hearts assigns waveforms (zone sounds) in the following way:

Element#  Note Low  Note High  Waveform 
--------  --------  ---------  -------------- 
    1         C0       F#0     Bd T9-1 
    2         G0        C1     Bd Hard Long 
    3        C#1        D1     Sd Elec12 
    4        D#1        F1     Sd HipHop6 
    5        F#1        A1     HH Closed D&B 
    6        A#1        C2     HH Open T9 
    7        C#2        C4     Clap AnSm 
    8        C#4        C6     Shaker Hip2

Yamaha messes with each of the zones in crazy ways and ties keyboard notes to voice parameters (AKA “key follow”). For 8Z Heavy Hearts, the most notable effect is how the Clap AnSm pitch follows the keyboard.

Arrangers (even Genos!) don’t have 8Z voices. They have standard drum kits where each MIDI note is a separate drum instrument. In order to make a PSR style using a DAW, one must translate the 8Z MIDI notes to standard drum kit notes. You need to assign appropriate drum kits (e.g., DrumMachine, Analog T9, House, Break or HipHop) to style parts 9 and 10 (MIDI channels 9 and 10) and copy the Heavy Hearts MIDI data to both Parts. Then, delete the notes that aren’t needed in a style part, compress each zone into a single drum instrument, and map the resulting “compressed” notes to the appropriate drum instrument(s). So, for example, all of the notes in C0 to F#0 might be compressed into the Kick T9 1 instrument (B0) in the Analog T9 Kit, which is one of the target drum kits.

I found two PSR drum parts to be enough. However, styles are flexible and you could assign a third (fourth, …) drum kit to one of the other style parts. There’s nothing in Yamaha styles that prevents this. It’s just that parts 9 and 10 (MIDI channels 9 and 10) are conventionally assigned to drum parts in a style.

I went with two PSR drum kits: Analog T9 kit and Drum Machine kit. Here is one possible assignment:

Note Low Note High Waveform       Instrument        Note#   Kit 
-------- --------- -------------  ----------------  ------  -----------
  C0 24   F#0 30   Bd T9-1        Kick T9 1         35 B0   AnalogT9Kit
  G0 31    C1 36   Bd Hard Long   BD Hard Long      24 C0   DrumMachine
 C#1 37    D1 38   Sd Elec12      Snare Analog CR   63 D#3  DrumMachine
 D#1 39    F1 41   Sd HipHop6     Snare Hip 1       86 F#3  DrumMachine
 F#1 42    A1 45   HH Closed D&B  Hi-Hat Closed Syn 91 A4   DrumMachine
 A#1 46    C2 48   HH Open T9     Hi-Hat Open T9    46 A#1  AnalogT9Kit
 C#2 49    C4 72   Clap AnSm      Clap Analog Sm    27 D#0  AnalogT9Kit
 C#4 73    C6 96   Shaker Hip2    Analog Shaker     57 A2   DrumMachine

A lot of detail, huh? Nobody said style conversion was easy. 🙂 In the end, I spread each zone across multiple drum instruments of the same type, i.e., assigning the Shaker Hip2 zone to a few different Analog Shaker sounds in the Drum Machine kit. Part of 8Z Heavy Hearts’ charm is the subtle sonic variation provided by each zone.

Trying to keep this all straight in the DAW piano roll is cognitively challenging. Did I say, style conversion isn’t easy? 🙂

Fortunately, one can loop four bar sections and play the MIDI through the arranger (Genos, in this case) just like a MIDI song. Then, it’s the usual tweak, listen, rinse, repeat edit process. When the MIDI is tweezed to your liking, you need to add MIDI markers to delimit the style sections. (BTW, leave a one bar MIDI set-up measure at the beginning.) Style section markers are:

    Set-up measure 1: SFF1 
    Set-up measure 1: SInt 
    Main sections:    Main A, ... 
    Fill sections:    Fill In AA, ... 
    Break section:    Fill In BA, ... 
    Introduction:     Intro A, ... 
    Ending:           Ending A, ...

At a minimum, you need a few MIDI set-up System Exclusive (SysEx) messages at the beginning of the SMF (measure 1, beat 1):

    F0 7E 7F 09 01 F7                 GM Reset 
    F0 43 10 4C 00 00 7E 00 F7        XG System ON 
    F0 43 10 4C 02 01 00 01 16 F7     Reverb type 
    F0 43 10 4C 02 01 20 16 00 F7     Chorus type

Reverb is the “Light Hall” preset and chorus is the “Tempo Cross 1” preset. The tempo cross delay is an 8-beat echo.

Which brings me to a necessary ingredient: crunch. 8Z Heavy Hearts gets a lot of its appeal from the Lo-Fi effect:

#  Parameter                   Val  Hex   Meaning 
-- --------------------------  ---  ----  -------- 
 1 Sampling Frequency Control    4  0x04  8.82kHz 
 2 Word Length                  98  0x62 
 3 Output Gain                   7  0x07  0dB 
 4 LPF Cutoff Frequency         56  0x38  12kHz 
 5 Filter Type                   1  0x01  PowerBass 
 6 LPF Resonance                63  0x3F  6.3 
 7 Bit Assign                    4  0x04 
 8 Emphasis                      1  0x01  On 
10 Dry/Wet                      88  0x58  D<W24
15 Input Mode                    1  0x01  Stereo

Since we need Lo-Fi on both style parts 9 and 10, I configured the variation effect as an XG SYSTEM effect. Parts 9 and 10 also require variation send (MIDI CC#94) set to 127. Add a CC#94 message to parts 9 and 10 in the set-up measure. Here are the MIDI System Exclusive messages to add to the set-up measure:

F0 43 10 4C 02 01 40 5E 13 F7       Variation type 
F0 43 10 4C 02 01 5A 01 F7          Variation SYSTEM 
F0 43 10 4C 02 01 56 40 F7          Variation return 
F0 43 10 4C 02 01 58 10 F7          Variation send to reverb 
F0 43 10 4C 02 01 59 10 F7          Variation send to chorus 
F0 43 10 4C 02 01 42 00 04 F7       Variation parameter 1 
F0 43 10 4C 02 01 44 00 62 F7       Variation parameter 2 
F0 43 10 4C 02 01 46 00 07 F7       Variation parameter 3 
F0 43 10 4C 02 01 48 00 38 F7       Variation parameter 4 
F0 43 10 4C 02 01 4A 00 01 F7       Variation parameter 5 
F0 43 10 4C 02 01 4C 00 3F F7       Variation parameter 6 
F0 43 10 4C 02 01 4E 00 04 F7       Variation parameter 7 
F0 43 10 4C 02 01 50 00 01 F7       Variation parameter 8 
F0 43 10 4C 02 01 54 00 58 F7       Variation parameter 10 
F0 43 10 4C 02 01 75 01 F7          Variation parameter 15

At this point, you could save the MIDI to “DresdenAtNight.sty” and load it into your arranger as an SFF1 format style. The arranger should create the style CASM segment. As an alternative, you can add a CASM segment to the SMF with Jørgen Sørensen’s CASM editor. You might as well download his OTS editor, too, and use it to add OTS voice settings to the new style as well. Or, you can do this sort of work on your arranger itself. Mid- and high-end Yamaha arrangers save styles as SFF2 format, which is one way to convert from SFF1 to SFF2. I highly recommend Jørgen’s site, tools and style creation tutorial.

BTW, you can recreate Dresden At Night on MODX (Montage). Create a new MODX performance with 8Z Heavy Hearts and Dark Bass. 8Z Heavy Hearts has the appropriate arpeggios by default. You’ll need to assign different arpeggios to the Dark Bass part. Modify effects as needed. Choose and add pad or lead voices to give your right hand something to do. Done! Use the Scene buttons to switch arpeggio groups.

Combo organ: Montage, MODX, Genos

Posted on March 23, 2021 by pj

Contemporary workstation instruments offer several options for combo organ emulation. Every workstation has at least a few internal combo organ waveforms. Korg Kronos, for example, has two Vox organ waves built in. Even the lowly Korg microKorg XL+ has two Vox waveforms (DWGS single cycle).

Yamaha MODX and Montage — my focus in this article — have a good variety of Vox and Farfisa waveforms. Yamaha Genos has a lesser endowment as we’ll see. Yamaha Reface YC shares sonic DNA (AWM2 and effects) with the Motif XF and will be the subject of a future post.

Motif, Motif ES and Motif XS

Models in the early Motif series primarily base combo organ patches on two waveforms:

Portable Electronic: Vox-y tone
Compact Electronic: Farf-y tone

You can hear these waveforms at work in the Tiny Combo Bars 1 performance and the Tiny Combo Bar 2 performance. The patches layer three are more elements playing Portable Electronic or Compact Electronic (respectively). Each element is filtered differently: low pass, band pass and high pass. The net effect is like several distinctive tab stops or drawbars pulled at once.

These waveforms are very old, going back to the original Motif (maybe S80) in the early 2000s. I’ll bet dollars to donuts that the Portable Electronic waveform is the basis for the 60’sOrgan voice (MSB: 0, LSB: 116, PC: 18) in PSR and Tyros keyboards. The 60’sOrgan voice was the sole combo organ mainstay in the arranger line for a loooong time.

Motif XF, Montage, MODX

Motif XF got a big shot of combo juice. Motif XF added several combo organ waveforms:

Fr All Tabs
Fr Bright Boost
Fr Flute
Fr String Lo
Fr String Hi
Fr Trumpet
Fr Piccolo
Fr Pedal
Fr KeyOff
Vx Drawbar1-3
Vx DrawbarIV
Vx KeyOff

The Farfisa (Fr) waveforms support emulation of specific Farfisa features: individual voice tabs (flute, string, trumpet and piccolo), the wicked Bright Boost knee lever, bass keys (pedal), and key off sound. The Fr All Tabs waveform covers one of the most common use cases — all of the tab stops turned on. Subtlety was not a hallmark of sixties combo organ music. 🙂

The Vox (Vx) Vx Drawbar1-3 waveform covers the three Continentel footage drawbars while the mixture drawbar is handled by the Vx DrawbarIV waveform. The Vox waveforms include a Vox key-off noise.

In terms of voice programming, one uses note shift to achieve different footage ranks. Passive filtering is emulated through filter type (low pass, band pass, high pass) and cutoff frequency. Of course, everything can be routed into insert effects for distortion, amp simulation, and other grunge.

Since Montage and MODX inherit all things Motif, these waveforms and the Motif performances are there for you. The Montage and MODX sliders allow control over individual voice elements. For example, choose the Raspy Tabs performance and assign slider control to element level. The Fr Raspy Tabs waveform-to-element assignment is:

El# Waveform     KeyLo KeyHi VelLo VelHi Coarse Level Cutoff XA Ctrl 
--- ------------ ----- ----- ----- ----- ------ ----- ------ ------- 
 1  Fr String Lo   C2    G8     1   127     0     97   255   Normal 
 2  Fr Trumpet     C2    G8     1   127     0     82   255   Normal 
 3  Fr Flute       C2    G8     1   127    24    120   236   Normal 
 4  Fr Pedal      C-2    B1     1   127     0    127   160   Normal 
 5  Fr String Hi   C2    G8     1   127    19     24   236   A.SW2 On 
 6  Fr KeyOff      C2    G8     1   127     6     87    80   Key Off

Different tabs are brought in and out by moving the corresponding slider. Assignable switch 2 turns on additional brightness. The low keyboard octaves play the bass (pedal) tones. Overall, this is a fairly controllable representation of a wheezy Farfisa Compact.

Because the sliders are not discrete, you can probably make up Farfisa tones which aren’t entirely authentic. But, really, should one care? 😉

Vox performances have similar control-ability. Here is the waveform-to-element assignment in the Vx Full Bars performance:

El# Waveform      KeyLo KeyHi VelLo VelHi Coarse Level Cutoff XA Ctrl 
--- ------------- ----- ----- ----- ----- ------ ----- ------ ------- 
 1  Vx Drawbar1-3  C-2    G8     1   127     0     75   255   Normal 
 2  Vx Drawbar1-3  C-2    G8     1   127    12     77   255   Normal 
 3  Vx Drawbar1-3  C-2    G8     1   127    24     91   255   Normal 
 4  Vx DrawbarIV   C-2    G8     1   127     0    127   250   Normal 
 5  Vx KeyOff      C-2    G8     1   127     4     68    85   Key Off

The first three sliders control the 16′, 8′ and 4′ Vox drawbar settings and the fourth drawbar controls the Mixture (IV) tone. Go ahead, just everything to eleven. 🙂

Montage and MODX FM

But, wait, there’s more! Montage and MODX have two FM combo voices: BOX FM Combo Organ and FM YC Combo Organ. Although these performances don’t sound authentic to my ears, they provide starting points for further programming. I haven’t heard the YC61 as yet, but I wonder if the YC61 combo emulations can be ported to Montage and MODX?

Genos

As I mentioned earlier, the arranger series has been historically short on combo organ sounds, relying on the old 60’sOrgan voice. Wheezy, raspy Farfisa tones are noticably absent. The 60’sOrgan voice sounds like the Portable Electronic waveform on which the Motif 1967 Keys performance is based.

Tyros 4 and Motif XF were introduced at approximately the same time. They certainly were together in the development lab during late 2009. Tyros 4 added four combo organ voices:

60sComboOrgan1: VoxContiComb1_Full_NoVib waveform
60sComboOrgan2: VoxContiComb1_Full_VibOn waveform
60sComboOrgan3: VoxCombi4NoVib waveform
60sComboOrgan4: VoxCombi4NoVib091117 waveform

Voices 1 and 2 capture one Vox Continental drawbar combination (Comb1) and voices 3 and 4 capture a second combination (Combi4).

Voices 1 and 3 are without vibrato. Voices 2 and 4, unfortunately, have an excessive amount of vibrato — almost painfully so. When I use voices 2 and 4 in a MIDI sequence, I dial down the vibrato depth using MIDI CC#77 messages. Vibrato frequency is about 5Hz. I also remove touch sensitivity by setting:

Velocity sensitivity depth to zero, and
Velocity sensitivity offset to 114.

An organ voice should not respond to touch (key velocity) — ever.

PSR, Tyros and Genos players shouldn’t forget the “hidden” Italian 60s organ voice (It60’sOrgan) in the GM2 sound set. On PSR and Tyros, you’ll find It60’sOrgan within the Legacy voices Organ subfolder. On Genos, you need to download GM2 and XG user voices to the USER voice folder. (See this thread in the PSR Tutorial Forum.) Of course, you can select
It60’sOrgan from a DAW (MSB: 121, LSB: 2, PC: 17) .

All-in-all, you can get a nice Vox tone out of Genos. Farfisa is still missing in action, tho’. Kind of an odd shortcoming of a keyboard with styles and a user base that want to play popular hits from days past.

In the next post, I’ll compare Reface YC combo organs against Montage/MODX (Motif XF). The result may surprise you.

What did you do in self-isolation?

Posted on June 15, 2020 by pj

Yes, this site still does music! 🙂

Several weeks ago, I decided to record the church tunes that I enjoy playing. It’s best to start with favorites, as most of you know how you come to detest a track after playing it over, and over, and over again during production. Energy quickly dissipates when micro-editing MIDI events or digital audio…

Before getting into production notes, here are links to the final tracks (all MP3). The goal was to crank out a new tune each week and send it to the folks in our music ministry. Some tunes are a little more polished than others. Please consider them “demo quality.”

Without going too far into the technical weeds, the primary sound source is Yamaha Genos™ and the primary vocalist is my spouse Fran. With the Mill Creek Chorale on hiatus — aren’t we all? — I was happy that she could contribute and have fun, too.

Production notes

So, how did all of this go down?

These demoes show off the Yamaha Genos as a sound source and production tool. I had two main subgoals:

Learn how to record a demo with Genos in either audio or MIDI format.
Learn how to mix down with Steinberg Cubase Artist and try out a few of the freebie plug-ins that I’ve collected.

By and large, Genos and Cubase were the main production tools although I back-slid into SONAR on a few occasions for MIDI editing. Old habits die hard. Workflow was not strictly linear from Genos to Cubase. In a few cases. MIDI and/or audio (stereo 16-bit 44,100 WAV) were slung back and forth between tools.

Genos is the sound source with one big exception: drawbar organ. When you hear B-3, you’re hearing Yamaha MODX through an Electro-Harmonix Lester K. I wanted to hear Lester K in musical context. It sits in a song pretty well and has more guts than the Yamaha MODX Leslie simulator. By itself, though, Lester K has some high-end swirliness in the upper drawbars, but in a track, it seems to mesh. You be the judge.

Emphasis was on speed. Get the tracks down quickly and finish a song each week ASAP. The Beatles used to call this recording “on heat.” Even so, it’s amazing how modern technology will drag you into the dank chasm of production minutiae. Don’t you just love hearing the same three measures fifty times while tweaking and tweezing. Not.

All vocals were recorded directly to Genos using its microphone input. Full backing and raw vocal tracks were exported to Cubase via WAV. Everything was processed and mixed in Cubase. The final mix was exported from Cubase as WAV, and then trimmed and converted to MP3 using Sound Forge Audio Studio.

Our God Is Here This was the first demo in the series and the process doesn’t get any simpler than this. All was recorded into Genos Audio Multi Recording. Find a beat, turn it on, lay down the organ part. Unfortunately, I didn’t plan for the ending, which is quite ragged. The organ is Genos in this case (not MODX). Kinda plain, huh? The bass is an overdub.

Audio Multi Recording is a nicely done sound-on-sound recorder a la Les Paul, minus tape hiss. There are two stereo tracks: main and sub. You can record directly to either main or sub, and bounce (sub+main) to main. There are options for punch in and overdub. Audio Multi Recording provides WAV import and export, functionality which eventually got a true work-out.

Audio Multi Recording keeps digital audio in a persistent project. A project resides in the internal Genos 60GB user solid-state drive and is always ready. The project remembers audio and mix settings without requiring explicit save and load user operations. That makes for a clean workflow. Export is the way to get digital audio into a WAV file and it mixes the main and sub on the way to WAV. In order to export a solo vocal track from sub, one needs to dial down the main and then wait while Genos writes the WAV file in real time. I wish there was a simple, direct fast export to WAV supporting both main to WAV and sub to WAV.

In The Day Of The Lord I quickly realized that I do need to think ahead and assemble a basic skeleton on which I could build a tune. (Duh!) In this case, Toontrack EZDrummer provided the drum patterns which I pulled together in Cubase. Genos played the MIDI drum track while I recorded the flute as a melodic guide and layered in the bass and organ — all recorded as audio. We then did a few vocal takes to Genos. I transferred all of the Genos audio as WAV into Cubase for the final mix. Vocal processing typically was light: a little pitch correction, EQ, and maybe double tracking. A touch of reverb (Cubase Revelation) blends everything together here.

Stop By, Lord This tune makes use of the Genos rhythm accompaniment consisting of main patterns and one-bar fills. I recorded a basic guide track in MIDI using the “BigBandBallad” style as the drummer. This meant switching the main and fill patterns with my left hand while playing the melody with my right hand. I layered in the piano, bass and horns, discarding the guide melody along the way. I added the B-3 organ (MODX through Lester K) in an audio pass. Everything was recorded and produced on Genos since we didn’t record vocals.

Psalm 95 If Today “If Today” makes full use of the Genos arranger features. I played the basic accompaniment track using the “Sunny Reggae” style. Whoever built that style, it must have been a labor of love and it fits this song quite well. I vocoded my voice. Both the accompaniment and vocal tracks where exported to Cubase for final assembly and mix down. I had a lot of fun adding dub effects and tons of reverb, Long live King Tubby!

Rise Up With Him “Rise Up” was recorded to MIDI, again using the Genos rhythm accompaniment as the drummer. The electric piano went down first followed by the bass. The B-3 organ is MODX through Lester K. Backing and vocal audio were exported to Cubase for final mix down. Overall, a pretty simple demo to pull together.

O Sacred Head I recorded the MIDI for this tune a long time ago — in the early 2000s on a Roland XP-60. The guitar picking was carefully edited and assembled (years ago!) from Twiddly Bits. I imported the XP-60 MIDI into Cakewalk, choosing Genos voices and effects. The Genos result versus the original XP-60 is amazing. Fran encouraged me to leave it as an instrumental.

This Is The Day This psalm is long out-of-print. A few years agao, I transfered a scruffy copy of the piano score into Sibelius. So, to kickstart this tune, I exported MIDI from Sibelius, restructured the sections, and humanized the piano as much as possible. I tried to keep the accompaniment simple adding just bass and horns. Once again, the backing and vocal tracks were mixed in Cubase. This demo is a good example of Arturia’s Plate-140 reverb — a freebie that Arturia gave away during the Christmas holiday. I love it.

Lead Me, Lord Another simple turn-on-the-beat-box, sound-on-sound production. Everything was recorded to Genos with the backing and vocal tracks exported to Cubase. (Another example of Plate-140, BTW.) The vocal harmony was generated by a TC Helicon Play Electric added in real time. Recording and production was dirt simple although it took a while to get the TC Helicon configured.

Alleluia! Love Is Alive This was the penultimate demo in the series. The basic track is a stripped down Genos “6-8PopBallad” style. Yamaha tends to over-orchestrate styles, so I kept drum, bass and guitars, tossing the rest. Instead of playing the basic track, I created the accompaniment using chord step-record. This MIDI Multi Recording feature lets a musician enter chords and sections from a lead sheet, quickly creating the song skeleton. You can even try different styles if you haven’t chosen one already. Once the skeleton is set, you expand the chord track into MIDI events, thereby obtaining the full backing track in a Standard MIDI File (SMF).

I added the Celtic violin by playing it into a free MIDI track. Using Sonar, I tweaked the tempo in the full MIDI song in order to add energy as the song progressively builds to the end. Finally, with the MIDI finished, I froze the backing tracking to WAV audio. The backing and vocal tracks were mixed down in Cubase with a little automation here and there to add vocal depth and double tracking.

Conclusions?

The preceding discussion is already a lot to absorb and to process. I’ll take a step back in a future post and try to summarize. All the best to ya.

SHS-500: Snap review

Posted on January 8, 2020 by pj

After analyzing the Yamaha SHS-500 Sonogenic from every possible angle (even the service manual!), I finally got one. On-line retailers are currently flooded with post-Christmas returns and bargains can be had. And so it was.

First, I must compliment Sweetwater for their prompt service and excellent packing. The SHS-500 was double-boxed. (The inner box was Yamaha’s original packing carton.) The unit is in excellent condition, matching Sweetwater’s assessment of its condition. Even though the inner carton has a big “DEMO” sticker on it, the Sonogenic is “like new.” Money saved and well-spent.

Since the Sonogenic was a demo, the initial settings are probably not factory. Thus, your out-of-the-box experience may be a little different than mine. I loaded the battery compartment with six AA batteries and turned it on.

Yamaha SHS-500 Sonogenic in fire-engine red

The internal speaker is not going to impress anyone. Sound quality is at roughly the same level as Reface and I never warmed to that. I’ll be playing the Sonogenic through either headphones, my trusty, portable JBL Charge 2 or a powered monitor. Sonogenic has a master EQ and it’s important to set it appropriately. My unit was set to “Line Out” and the sound through the speaker was weak. Changing to the “Speaker” EQ setting was much better. Be sure to change back to “Line Out” when connecting to an external powered monitor. (Or “Boost,” or “Mild”.)

The SHS-500 is quite solid in the hands — much better build quality than the new PSS series or the SHS-300. Key feel is comparable to Reface. After playing the Sonogenic, the PSS keys have a cheaper feel. Yes, you get what you pay for. The SHS-500 is like a Reface keytar.

Natch, the first thing was quick tour of the sounds. Every panel voice has a DSP effect. (See the table below for default assignments.) Sound quality is on-par with good PSR E-series voices and in a few cases, S-series. The SHS-500 is not a Genos. 🙂 However, the SHS-500 is better than PSS by far.

The House Kit has the same program selection numbers as the House Kit in the PSR-E463 and PSR-EW410. These instruments and the SHS-500 are the only ones with this “House Kit.” Go figure.

My favorite voices are the Electric Piano, Jazz Guitar, Electric Bass, Synth Bass, Piano & Pad, Strings, Flute, Tenor Sax and Harmonica. Electric Piano with the Tremolo DSP effect is nice. Can’t wait to try these out with my backing tracks. Here’s a few more snap opinions.

I’ve never been that excited by the PSR synth voices although Quack Lead, Under Heim and Analogon can be fun. Drop Quack Lead down an octave or two for an alternative synth bass.
The electric guitar is OK and the DSP distortion effect is welcome versus a static sampled overdriven guitar. However, the DSP effect is not up to the PSR S-series, Genos or MODX, that’s for sure. It’s an early Yamaha algorithm.
The main piano is bright — think “house.” The piano in the layered voices is warmer.
The tenor sax needs to be played stylistically. The low end gets into baritone territory — a plus.
The harmonica is decent enough to go a little Jon Batiste or Stevie with the thing.
A few of the voices (e.g., flute, tenor sax) have vibrato sampled in. If you’re a PSR-type person, you’ll recognize these as “Sweet!”
The LPF is a bit of a let-down. One can hear changes due to cut-off, but a certain dynamic aspect is missing.

The DSP effects sound a little over-done. It’s easy enough to strip the effect off by dialing it out with the Effect Control knob. One might get tired of doing this after every voice change, which is why I want to experiment with MIDI Designer as a graphical front end for the Sonogenic.

In addition to the default DSP effect, the Sonogenic sets the octave which is appropriate (in some sound designer’s view) for the instrument. Change the voice and you change the octave, too. Depending upon the scenario, this could be a drag. There isn’t a way to go directly to a voice; you need to spin the Select knob and step through the voices — another motivation for a MIDI Designer front-end.

Jack positions all seem well thought out. The USB and MIDI DIN connector are hidden behind a rubbery cover. The MIDI DIN connector is the same as the Reface connector and takes the same breakout adapter to produce 5-pin IN and OUT.

The audio Line Out is mono. (Yes, mono, according to the Service Manual.) The headphone output is stereo. If you need stereo, give the headphone output a try. Dunno if the waveforms or effects are stereo, but the stereo signals are sent to the headphone jack. (The DAC is an AK4430ET, BTW.)

The SHS-500 includes a PA-130 power adapter. I have a PA-150 plugged in at all times and it works just fine with the SHS. The PA-150 supplies the same voltage and has a higher amp rating. All good.

Overall, the Sonogenic SHS-500 is worth the (reduced) price. Will I take it to rehearsals? Heck, yeah! It’s a shame that Yamaha left at least one organ patch out of the voice set. There is enough here for those weeks when organ is not in the church gig spotlight. Almost wish the SHS-500 and Reface YC were combined into the same ax…

Early wave table and FM synthesis

Posted on December 31, 2019 by pj

Discussions about Yamaha Montage/MODX AWM2 and FM-X sent me digging into the past to unearth early AWM and FM implementations in order to get insight into today’s tone generation hardware. Although Yamaha do not publish design information about their proprietary SWP, SWX, SWL, etc. processors, they have published datasheets for their merchant line of LSI products. Yamaha were very active in the mid- to late-1990s when desktop music (Soundblaster, XG, Sondius, etc.) was king.

The Yamaha YMF278B OPL4 was one such LSI component. The OPL4 combines a 2-/4-op FM synthesizer and a wave table synthesizer on a single 80-pin quad flat pack (QFP). The FM synthesizer can:

Generate 18 voices in 2-op modes or 15 2-op voices plus five rhythm sounds.
Generate 6 voices in 4-op mode with an additional 6 voices in 2-op mode, or 6 voices in 4-op mode with an additional 3 voices in 2-op mode and five rhythm sounds.

The FM synthesizer has eight selectable waveforms and generates a stereo output. The wave table synthesizer can generate 24 voices simultaneously (i.e., 24 voice polyphony) producing stereo output at a 44.1kHz sampling rate with bit depths of 8-, 12- and 16-bits. Wave ROMs up to 32Mbits are supported with up to 512 wave tables.

The OPL4 has six sound channels which can be sent to an external DAC (YAC513) or a digital effects processor (YSS225). Sadly, documentation for the YSS225 cannot be found on-line. The YSS225 is said to perform reverberation, echo, flange and other effects.

The FM and wave table synthesizers are two separate hardware units. I wouldn’t be surprised if this is still the case in the modern day SWP70 Standard Wave Processor. Separation lets the engineers optimize the synthesis hardware for a particular synthesis type.

Wave table synthesis

The OPL4 does not implement AWM2 synthesis. The synthesizer does not have the AWM2 filter hardware. This is not too surprising because in that era, Yamaha regarded AWM2 and its analog-like filter as a special competitive advantage. Why would they give that same advantage to other sound card vendors? It’s a safe bet, however, that the XG-compliant variants are full AWM2.

Nonetheless, a peak inside gives us a look at Yamaha’s wave table machinery. The synthesizer consists of a synthesis core that fetches waveform samples and waveform meta-data from external wave memory.

Quoting the OPL4 data sheet:

The wave table synthesizer can generate up to 24 sounds simultaneously. Each sound is referred to as a “channel”. The channels are numbered from 1 to 24. These numbers are called “channel numbers”.

Wave table synthesis is controlled by a few hundred registers. The main control CPU writes common and channel-specific synthesis parameters into the registers. The synthesizer reads the registers during each synthesis macro-cycle and produces a new sound sample for each channel. The channel-specific control registers are organized into register groups. Each group consist of 24 registers, i.e., 24 values of a specific synthesis parameter type, one value per channel. A quick glance at the table below clarifies the register organization and the wave table synthesis parameters. Parameters for envelope generation, pan, LFO control, etc. are easily identifiable. (The YMF278B data sheet has the details).

YMF278 wave table synthesis control registers

I conjecture that today’s SWP70 is organized in a similar way. The CPU-SWP70 communication bus is a memory bus that gives the CPU direct access to the SWP70 synthesis control registers. Think about it. With 128 stereo AWM2 channels, there are several hundred (thousand!) synthesis values which must be configured at the hardware level. Software’s job is easier and fast by making the synthesis registers (channel-specific parameter value) directly accessible.

The waveform data and meta-information in external memory cosnsist of two parts: Up to 384 waveform headers and the waveform sample data. Each waveform header is 12 bytes containing:

Wave data start address
Loop address
End address
Voice parameters: LFO, VIB, ADSR, etc.

Today’s wave table is probably similar albeit much bigger. Explore Yamaha’s Universal Voice Format (UVF) and you’ll see what I mean.

FM synthesis

The OPL4 supports 2- and 4-op frequency modulation (FM) synthesis. Quoting the data sheet:

The part that generates one sine wave is called an “operator”. A combination of these operators is called an “algorithm”. The first stage operator (see diegram below) is called the “modulator” and the second stage operator is called the “carrier”. The frequency and envelope can be set for each operator. “Feedback FM” is available to generate a wider range of sounds.

Like the wave table synthesizer, the FM synthesizer has a large table of common and channel-specific synthesis parameters. The register table organization is a little more complicated. Quoting:

The OPL4 has 36 circuits that generate a sine wave. A circuit which generates a sine wave is called a “slot”. A sound unit which is generated by combining two or four operators is called a “channel”. There are two kinds of sound generation control registers: registers settable in slot units and registers set in channel units.

In 2-op mode, two slots are used to generate on FM sound. With 36 available slots, 18 channels of sound can be generated. In 4-op mode, four slots are used to generate one FM sound. Six channels are generated using 24 slots.

Whew! Given the two dimensional nature of register organization, addressing a specific parameter value for a specific operator is a complicated matter. (See the data sheet for details.) Without going a deep dive into register addressing, here is an image showing common and channel-specific synthesis parameters.

Summary

I would say that the overall architecture today (SWPxx) is not unlike the architecture of yesteryear. The number of synthesis parameters, of course, has exploded with new features in the wave table synthesis hardware (filtering!) and FM synthesis hardware. Modern FM can route FM output samples to AWM2 wave table filters, adding many wrinkles to datapath and control design.

The main CPU is responsible for channel allocation as notes are played and for channel deallocation as notes are released and completed. Once a channel is allocated, the main CPU must write the appropriate voice parameters into the channel registers. Then, it’s up to the synthesizer hardware to crank out a new sound sample at a 44.1kHz rate. Of course, the per-channel sound samples must be mixed and routed to the DSP effects processors. I would love to get a look at the mixing and DSP processing.

I hope this trip into the past gives you some insight into present-day AWM2 and FM-X hardware and an appreciation for the complexity and sheer number of details at the 10,000 foot level of digital synthesizer design.

Yamaha hold many patents on wave table and FM synthesis techniques. I recommend U.S. Patent 5,250,748 (1993) which describes the digital filter in AWM. For the modern era, I suggest U.S. Patents 8,779,267 (2014), 8,957,295 (2015) and 9,040,800 (2015).

Remie: A Christmas Story

Posted on December 30, 2019 by pj

My Yamaha PSS-E30 Remie review promised updates about how Remie works out in the real world with a two year old. Here’s a the first update (and why we moved out west to be with our grandson).

Background: Our grandson attended Kindermusik classes while he was an infant and, man, we can see the effects already. He also hangs with older kids and his big-kid grandfather (me) who all play keys, so playing keys already seems like an every-day activity.

When he comes over to our house, we put on music, or he and I sit down at the Yamaha MODX or Genos, depending on what’s set up and handy. He is in love with the MODX Superknob and the built-in beats, now referring to beat music as “orange music.” Orange is his favorite color and he will literally ask us to play “orange music”. One wonders if he has synesthesia or if he just likes the occasional warm orange glow from the MODX Superknob.

Well, come Christmas day, he unwrapped Remie and broke into a joyful smile. He quickly started pushing the start/stop button; Do kids understand icons that early? We dropped a few beats and he literally was dancing along. So, I would say the first encounter with Remie was quite successful!

A few minutes later, we caught his mom (a former wind player) trying different features and taking a quiz. Couldn’t have been better. We’ll see how Remie works out in the long run.

Hey, Yamaha! You missed an opportunity, tho’. Kids love the Superknob. Your next keyboard for kids should have a Superknob on it!

Merry Christmas and Happy New Year! (And support art/music education).

Just like starting over

Posted on November 4, 2019 by pj

I’m playing with a new group of liturgical musicians and am having great fun.

The two biggest challenges when playing with a new group are 1. listening and 2. picking up new music. Both challenges are opportunities for growth.

Listening is always key. As a synth player, I’m a bit of a frustrated orchestrator. Instruments like the Yamaha MODX and Genos offer a wide palette of acoustic and electronic sounds. The challenge is to listen carefully and find the right sound and part in the musical context. The context, of course, is the song and the other players — what the song needs, the instrumentation, what instrumentalists are playing, what singers are singing, dynamics and so forth. My goal is to select an instrument and improvise a part to complement the other instrumentalists while making the song stronger.

My last group was small: piano, acoustic guitar, sometimes drum, and me. That left a lot of musical space including exposed solos, fills, left-hand bass (as long as it didn’t interfere with the pianist) and foundation (e.g., pads, B-3 organ, etc.)

The new group is much larger: piano, guitar, drums, two flutes, viola, trumpet and trombone. There’s a lot going on! I’ve played with woodwinds and strings before; full-on brass is a new situation for me. There is still space, but careful listening is needed in order to find it. Obvious ideas include double reeds (oboe), French horn, woodwind ensemble, ensemble strings, cello, contrabass, pipe organ and B-3 organ (when the music calls for it).

With all of that going on already, it’s important to be part of the blend and to not overemphasize existing parts. Nor do I want to step on anyone’s part! For example, the flutists and viola contribute introductions and musical interludes such as an instrumental verse of a hymn. It’s going to take listening, time and experience to find the find complementary part(s). Conventional wisdom in scoring claims that acoustic instruments make it easier to fool the ear with electronic emulations. Thus, it makes sense to keep the real-deal acoustic instruments front and center.

Last Sunday, we did a rendition of “When the Saints Go Marching In” in remembrance of All Souls Day. Playing with the brass was a genuine kick. Challenge #2 — new music — I’ve never played New Orleans-style traditional jazz before. Although there are a lot of blue notes, the phrasing is unlike the gospel or Chicago-style blues that I’m used to playing.

So, hey, what to play? Clarinet and euphonium. New Orleans jazz is “lead and fill” or “call and response.” I downloaded a MIDI file to study and cop a few clarinet licks. I wrote out a simple clarinet part with a few fills and lines to harmonize what I thought the brass would play, assuming that the trumpet would take the lead. Euphonium-wise, an oom-pah alternating root (1 and 3) and fifth (2 and 3) was good enough to get started.

Try as I might, I just couldn’t get the two parts and hands going at the same time and settled for the clarinet line alone at the gig. Maybe next time… I think I may ditch the harmonization idea and play (around) the melody, too.

Patch-wise, you can’t always get what you want. I practiced the clarinet part on Genos using its Super Articulation 2 (SA2) clarinet which is darned sweet. I programmed a clarinet/eupohonium split on Yamaha MODX, but the MODX clarinet is not in the same league as the SA2. Compared to Genos, it sounds cheap. MODX (Montage) does have a decent euphonium, however, and maybe it’s better to go low than go high next time!

Yamaha, how ’bout a euphonium on Genos and SA2 on MODX?

That won’t stand in the way of the fun. In the meantime, there’s more than enough to keep me busy.

Update about the updates

Posted on October 25, 2019 by pj

Yamaha Genos V2.0 is on the way

Yamaha have updated their short video about the Genos V2.0 update. The release date is now specific: 15 November 2019. There was considerable squabbling on the forums as to what “Winter 2019” meant. I’m glad that Yamaha has put the question to rest.

The other big tidbit from the new video as to do with the “Genos V2.0 Superior Pack.” The new content will include 50 new styles and 68 voices including Super Articulation 2 voices. I’m not a big style hound, but new voices are always welcome! I’ve still got plenty of room in expansion memory and can’t wait for the new content. I’m looking forward to the Chord Looper, too.

[Update] The Yamaha Europe site has further details. The Genos Version 2.0 Superior Pack includes SArt2 Premium voices such as “Pan Flutes,” “Female Vocals,” and “Trombone.” The page shows thumbnails for the Yamaha Musicsoft Premium Expansion Packs of the same name. This might be a little disappointing to users who already own these packs. I have “Female Vocals” already. Of course, that’s just icing and we still need to taste the whole cake.

Improvements have been made to expansion pack installation (Yamaha Expansion Manager). Yamaha have also improved Genos Style Creator, which was looking rather long in the tooth. Other improvements include new portamento functionality, sorting playlists alphabetically, and an increase in the number of USER effects which can be stored.

Additional improvements flash by near the end of the video. (Look for the flying boxes!) Unfortunately, the English is a little rocky and its hard to tell what some of them actually mean! One useful improvement is the addition of USER voices to FAVORITES. (?) I hope they allow USER styles in chord step record because I didn’t see this mentioned.

Yamaha are listening. They cite user feedback as the source for many of these enhancements.

BTW, some folks have noted an increase in the USA Minimum Advertised Price (MAP). Please remember that all dealers cannot publicly advertise below MAP as part of their dealership agreement with Yamaha. That doesn’t mean selling at MAP because that would be illegal price fixing in the USA. If you want a good deal, be sure to call around, especially smaller focused dealerships like Audioworks CT. The large on-line retailers don’t have as much incentive to negotiate or to offer a better price below MAP. Smaller dealerships are often more flexible.

Yamaha MODX update V2.0 is here

Yay! The MODX V2.0 update has dropped! I’m downloading now and will be installing shortly.

Yamaha have posted a new MODX Supplementary Manual and a new MODX Data List PDF in the downloads section of the MODX Web pages. You’ve probably already seen the list of new features as implemented in the most recent Montage update:

New effect types have been added: VCM Midi Filter, VCM Mini Booster, Wave Folder.
52 new Performances have been added.
The Pattern Sequencer function has been added.
You can now play songs, patterns and audio files from the Live Set display.
Super Knob Link has been added to the data that is recorded in the Scene function.
Keyboard Control has been added to the data that is recorded in the Scene function.
Increased the range of the LFO Speed parameter.
You can now connect MIDI equipment via the USB TO DEVICE terminal.
The Global Micro Tuning settings have been added.
The Audition Loop setting has been added.
Improvements have been made to the user interface.
The sequencer storage capacity (total User Memory) has been increased from about 130,000 to about 520,000 (for Songs) and about 520,000 (for Patterns).

The new Performances are listed on page 17 of the new Data List PDF (version c0). The new Performances are numbered from 2144 to 2195. Laser Trumpet?

Not going to the gym today… 🙂

Installing the MODX V2.0 update

The first thing to note: This is a major update.

I don’t just mean that as a compliment to Yamaha. The software engineers had to touch many, if not all, of the major internal data structures. You must perform a complete back-up before attempting installation as you will need to initialize all data and then reload your back-up file.

Please read the installation directions before starting. The directions clear state that all of User Memory (Library Data, User Data, etc.) will be initialized. Be sure to do a complete back-up following the directions on pages 60-61 of the Owner’s Manual and pages 201-202 of the Reference Manual. You want to write a back-up file, also known as an “ALL file” or “X8A” file by its extension. A back-up file saves the whole shee-bang including your libraries.

Follow the steps in the installation guide. The installation process takes about 4 to 5 minutes. If everything is successful, you will see messages like:

Searching for the updater ... OK

MODX updater 2.00.1

Preparing ... OK (current version 1.10.0)
Updating ... OK
Verifying ... OK
Finish.
Please turn off.

Turn MODX off, remove the USB drive with the updater, and turn MODX on again. Navigate to the System Settings by pressing [UTILITY] > [Settings] > [System]. I pressed the “Initialize All Settings” screen button first and then pressed the “Initialize All Data” button. (Deep breath.) Yamaha’s installation directions should be a little more specific here as to which buttons to press.

The initialization steps will, of course, wipe everything clean. Next, insert the USB drive with your back-up file. Navigate to the load contents page, i.e., [UTILITY] > [Contents] > [Load] and select the “Backup File” content type. Find your back-up file on the USB drive and re-load your content. If all goes well (modulo power failure, cosmic debris, pulsars, etc.), you should be good to go again.

Sand, software and sound

Electronics and computing for the fun of it
