Hammond M-solo announced

Posted on by

For some reason, the best news pops up over the weekend. In this case, it’s announcement of the four-octave Hammond M-solo tone-wheel organ+. You got your drawbars, percussion and scanner controls, and four-octave keyboard in one compact unit. Hammond is pitching the M-solo as a second board to add over your other stage instruments (e.g., slab piano). Four octaves, though, is enough for real two-handed sport.

“The 8 pound M-solo features 49 keys, driving our “MTW II” Drawbar engine as found in our XK-4 Organ. All the essential HAMMOND ingredients are aboard, like Vibrato-Chorus (C1,C2,C3 etc.) and Touch-response percussion. Our high-definition digital LESLIE™ is on hand.”

Hammond need to hire a native English-speaking tech writer to edit the M-solo manual right doggone now. The grammar is horrible. Please.

The Hammond M-solo has four engines:

  • MTWII tone-wheel organ (polyphony: 61)
  • Transistor organs (polyphony: 96)
  • String/vocal ensemble (polyphony: 96)
  • Polyphonic synthesizer (polyphony: 8)

You can read all of the Hammond M-solo specs here. The drawbars control mix/timbre for all four engines. You can store up to three patches.

The polyphonic synthesizer is a two oscillator (triangle, sawtooth, square, pulse main and sub osc), filter and envelope affair. No mod or pitch-bend wheels; articulations are produced by pushing the (percussion) buttons.

The transistor organs and string/vocal ensemble are throw-backs to yester year (the 70s).

The goes-ins and goes-outs have the essentials: expression pedal, stereo 1/4″ jacks, phones, AUX IN (3.5mm), USB-B TO HOST, 5-pin MIDI IN and OUT, and something labelled “Leslie FAST”. The AC adapter in looks like a Casio-standard jack, uh-oh.

Someone floated a Japanese price on Keyboard Corner, but I could not verify it on the Suzuki web site. I suspect that Hammond are aiming for the magic $999 USD price point. I wouldn’t expect much for $1,000 these days, so forget about luxury features. Hammond Suzuki are offering a limited number of units in burgundy color.

The big (errr, small) spec that jumps out at me is 7 pounds 15 ounces (3.6kg). After 71 years, I have herniated just about everything that can be herniated. Small is good; light is good.

For me, I see the M-solo replacing my Yamaha Reface YC. I mainly use the YC at rehearsals — quick in, quick out. I’ve used the YC at the church job, when slugging MODX is too much for my health. Several things about Reface YC really annoy me: the fast rotary speaker speed, its chorus/vibrato and the three octave keyboard. Mini-keys are somewhat annoying, but hot-damn, either my left and/or right hand runs out of space on that friggin’ three octave keyboard. Three octave keyboards should be outlawed. No diggity.

Demo-wise, the organ demos have me interested. If you only have time for one video demo, play this one.

Definitely a big step up from Reface YC. The poly synth demo sounds are pretty weak. I’m hoping to get one or two good pad sounds out of it, maybe a flute-y lead. The string ensemble is a little too “PAiA Stringz’n’Thingz”, but I expected that. (Solina? Not so sure.) I don’t need much for rehearsal. And the M-solo will scratch my occasional itch for combo organ.

Isn’t this awkward?

Posted on by

I checked out an interesting observation made on the Yamaha Musicians Forum. The Steinberg Online Shop is currently (and temporarily) kaput.

“Our online shop is run on our behalf by a third party, Asknet Solutions AG. Unfortunately, Asknet has entered into self-administered insolvency, and consequently Steinberg has decided to engage a new trusted business partner to restore our online shop.”

“The Steinberg online shop is currently unavailable. A wide range of Steinberg products is available via our worldwide network of authorized resellers. To find your nearest Steinberg reseller, use our reseller locator. We know you may have questions about this unusual situation, so please read: Online Shop Info”

Makes it rather awkward to synchronize the Cubase 13 release (MIDI 2.0) with the Montage M or GENOS II announcements.  🙂

Launches are never that easy or turbulence free!  🙂

KORG Keystage MIDI 2.0

Posted on by

Thank you Gearnews and KORG for rescuing us from endless discussions about the meaning of “M”. [Be Zen. Labels are useless and wrong. Accept.]

A retailer slip-up previewed the new KORG Keystage line of MIDI 2.0 controllers. The retailer’s page is now gone.

Hmm, Gearnews and other big-name sites have been rather quiet about the Yamaha Montage M. Perhaps they have review units already? Rumor-wise, mark October 9th on your calendar. Gearnews, by the way, is a subsidiary of Thomann.

The Keystage are handsome beasts. The big news is polyphonic aftertouch (Polytouch®) in partnership with ASM. Neat! Keystage are equipped with an audio interface. Each of the eight parameter knobs has its own OLED display. Slider fans will be disappointed, however — no faders.

The 49- and 61-key models are light: 9.3 pounds and 11 pounds, respectively. Both have 5-pin MIDI IN and OUT. The 49 is priced at $599 USD (MSRP? MAP?) and the 61 is $699.

A small music/tablet rest is provided. The rest can be positioned at center or left/right. This is thoughtful.

From my own perspective, I wonder if the two pedal inputs support an expression pedal in addition to footswitch? At these prices, it should. The front panel seems a little short on assignable buttons. I like to use buttons for patch changes while playing. Hope it can send a full Bank MSB, Bank LSB, Program Change MIDI message sequence — my pet peeve and soapbox issue. Hope it’s all MIDI 1.x backward compatible, too.

Ridin’ the E-bus

Posted on by

Jan was kind enough to send me his thoughts about the “M” in “Montage M”. He hears evidence of MPE — MIDI Polyphonic Expression — in at least one of the audio examples posted by Yamaha.

Well, my ears probably aren’t as finely tuned as his, but his conjecture (“M” for “MPE”) makes sense. By now, you’ve probably seen the list of new Cubase 13 features including MIDI 2.0. Cubase has supported MPE for quite some time, and oddly, Yamaha synths (when used as external controllers) do not support MPE! Thus, it’s time for Montage M and future Yamaha synths to catch up with their Steinberg cousins.

MIDI 2.0 has a number of MPE-like features to control individual notes, e.g., pitch bend individual notes instead of all active notes in a MIDI channel. Some analysts regard MPE as a “bridge” to MIDI 2.0 with MIDI 2.0 as the final destination.

I was happy to leave it there, but my mind wandered down to the circuit level. In particular, I wondered if Yamaha’s internal controller design is up to the task of MPE and MIDI 2.0. MIDI 2.0, after all, increases controller resolution up to 32 bits and note velocity up to 16 bits. That’s quite a leap from MIDI 1.x 7-bit resolution in both cases (modulo the few situations where a few more bits are set aside).

Web discussions usually focus on synthesis and ignore control implementation. With the change to MIDI 2.0, suddenly the control infrastructure requires examination, too, and possibly an update. (“We cannot develop the current MONTAGE any further.”)

So, how are key, knob, slider and button gestures detected and communicated in a mid- to upper-tier Yamaha synth/arranger? By mid- to upper-tier, I mean those instruments which incorporate an SWP70 (SWP50/51) tone generator IC.

In the case of Montage (and MODX), keys, knobs, sliders and buttons are scanned by dedicated microcontrollers. The Montage has three microcontrollers:

  • E-PNS4: 40MHz ARM Cortex-M3 32-bit single core microcontroller (MB9AF131NBPQC)
  • E-VKS: 40MHz ARM Cortex-M3 32-bit single core microcontroller (MB9AF131KAPMC)
  • E-PNS3: 10MHz Toshiba 8-bit microcontroller (TMP89FW24AFG-7KH4)

E-PNS4 scans knobs (24 lines, 12-bit ADC) and the left/right front panel switches. E-PNS3 scans the sliders (8 lines, 10-bit ADC). E-VKS scans the keyboard.

The three microcontrollers and the Master SWP70 tone generator are connected by an I2C bus which Yamaha calls the “E-bus”. The three microcontrollers send events directly to the tone generator. The event message stream does not pass through the ARM host CPU (running Linux). Latency is minimized thanks to the direct path. And, as far as internal synthesis is concerned, the events are not converted nor passed through conventional MIDI links.

The ARM host CPU gets its E-bus messages from the Master SWP70. The Master SWP70 generates an E-bus interrupt request (SWP_EIRQN) when message data is available.

The best way to describe I2C is “poor man’s Ethernet.” I2C is serial and requires only three wires: clock (E-SCL), data (E-SDA) and reset (E-IC). I2C can send multiple bytes in a single bus transaction.

I found three European patents that describe the E-bus: EP1235202A2, EP1235202A3, EP1235202B1. Basically, Yamaha (re)filed three separate patents with the European Patent Office in order to extend the life of the IP. The patent title is “Bi-directional serial bus system for electronic musical instrument,” and the inventors are Shinya Sakurada, Akira Iizuka, Harumichi Hotta, Shizuhiko Kawai, Kozo Tokuda, Masaki Kudo. The first patent was published August 28, 2002.

There are two message data formats:

  • Standard data: 5 bytes in length (3 data bytes)
  • Extended data: 17 bytes in length (15 data bytes)

Generally, events are communicated in the 5-byte, standard data format. The following table (“FIG. 8”) is taken from the patent. It summarizes the E-bus events.

You probably picked up on the similarity to standard MIDI 1.x events. There aren’t any channels, however. The low-order nibble of the first data byte provides additional event-specific information (port number or 4 additional velocity bits).

This analysis opens a can of worms. Will Montage M scan analog signals at 10-bits? 12-bits? Can the existing E-bus protocol communicate values measured at higher resolution? Can the stock SWP70 tone generator at the receiving end of the event stream interpret and respond to higher resolution events? How will low resolution values be up-scaled to 32 bits? Is that even required by the MIDI 2.0 spec?

I guess we’re gonna find out! We should all thank the engineers who took on this rather unglamorous task.

Yamaha synthesizer sneak peek

Posted on by

Blake comes through! [Thanks, Blake.] If you’re interested in Montage M, go direct to the official sneak peek on YamahaSynth.com. Do not pass GO. Save $200 for your new Montage M, if you collect it. 🙂 The sneak peek page has Soundcloud audio demos.

Check out the large subdisplay on Montage M!

The “Vegas nightline” shots pretty well confirm the leak pictures. I loves that subdisplay above the knobs and sliders. It’s much bigger than Genos, can handle graphics, and will prove to be more informative than Genos. I wonder if GENOS2 will get the same subdisplay? That would be grand!

Jason’s labelled flow diagram (from YamahaSynth.com)

I’m trying to make sense of the fuzzy screenshot which looks like an effects routing diagram. Yamaha have clearly done some user interface work, here. Maybe the boxy icons open into parameter tables?

[Update: Jason at YamahaSynth.com did everyone a service by labelling the fuzzy flow diagram. It is the classic synth signal flow. At Yamaha Musicians Forum, a member noted the AN1x color scheme, and then Saul let on that AN-X is included in the M. Good times ahead!]

I don’t see texturing on the white piano keys (in the picture with the ribbon controller). I suspect that the “spy pictures” are an earlier prototype or sound development ‘board. I still have hopes for a decent 88 keybed. The grand piano audio snippets have that distinctive CFX brightness and clarity. The fusion-y “bass effect” audio example is 70s cool and I dig the playing.

The organ Soundcloud snippet has many pulses running fast — my own included. Dare we hope for Stage YC technology? I’ll settle for the improved, Stage YC rotary speaker sim. Yamaha must and will keep reserve special tech in order to differentiate product lines (Montage M vs. Stage vs. P-series).

The Soundcloud examples skew toward bread and butter sounds. The selection of examples will not please the synthbois. Maybe Yamaha is holding AN-X fire for the full Montage M announcement?

This is the way to create excitement for a product instead of boga-zoid teaser videos. The Genos (gen 1) pre-announcement teaser, for example, had nothing to do with the actual instrument — it was a promotional video for some idiotic, boring producer. I hope the GENOS2 roll-out is intelligent, too. Customers are not stoopid.

Now we have something to look at! See you later… If info is slow to appear on my site, it’s because WordPress has suddenly decided to inflict the Gutenberg UI on me. 🙁

Yamaha NU1XA upright hybrid

Posted on by

Yamaha’s big reveal of the week is the AvantGrand™ NU1XA with a “renewed sensor and sound system” — a substantial update to the NU1X hybrid piano.

The NU1XA combines the action of an acoustic upright piano with sensors, digital sound generation and immersive audio system. Yamaha claim improved key touch and repeatability. The updated double sensor detects movement of the keys and hammers and incorporates an “Articulation Sensor System” which is responsive to performance gestures (force and timing). The NU1XA has a GrandTouch™ pedal.

Yamaha Articulation Sensor System

The sound system is a new design which reminds me of the CSP-295 digital piano. The sound system uses a tweeter horn structure that allows high-frequency sounds to resonate in front and behind the instrument. Woofer speakers near the player’s feet radiate upward so that sound resonates through the instrument. The goal, of course, is to create an accurate, immersive sound field similar to an acoustic grand piano.

The sound system specs out this way. Amplifiers: (40 W + 45 W) × 2. Speakers: (16 cm + 2.5 cm (dome) with Bidirectional Horn) × 2. Not tri-amplified like the CSP-295 and CLP-785, but respectable and similar to the current NU1X.

The NU1XA has the digital technology that we’ve come to expect from the Clavinova line:

  • Virtual Resonance Modeling (VRM)
  • Grand Expression Modeling
  • Yamaha CFX and Bösendorfer Imperial main piano tones
  • Binaural sampling (both CFX and Bösendorfer)
  • Four fortepiano tones

It has the touch-sensitive control panel from upper-end CLPs and Smart Pianist support.

Taking a quick browse through the manual, the NU1XA has all of the Clavinova’s song playback and recording features. It also has 5-pin DIN MIDI! The voice list is a little short on tones tailored for pop and jazz — just one jazz organ tone, for example. No XG or rhythms.

Newly announced Yamaha NU1XA hybrid piano

The Yamaha AvantGrand NU1XA will be available starting November 2023. Suggested retail prices (Japan):

  • Black mirror polished finish: 473,000 Yen (~$3,200 USD )
  • White mirror polished finish: 539,000 Yen (~$3,700 USD)

Of course, release and pricing depend upon region. Allowing for tariffs and such, those are reasonable prices (hopefully). I presume that the NU1XA will replace the current NU1X which sells for $7,400 (USD MAP) in polished ebony. Who knows where USA pricing will land?

The overall product form resembles a short upright (tall spinet?) and is not as big and bulky looking as the AvantGrand™ N1X. I could see having an NU1XA in our home where the more expensive N1X ($10,000 USD) would appear out of place.

Without hesitation, I’m going to give this one a try once it becomes available. I’ve already established the need for a decent practice instrument leaving orchestra instrument sounds, organs, etc. for MODX and GENOS (gen 1).

“M” for multi-core? Multi-touch?

Posted on by

One phrase from the Sayonara Montage announcement sticks in my mind: “As much as we would have liked to, we cannot develop the current MONTAGE any further.”

So, how might the current Montage platform be improved?

SWP70 Standard Wave Processor

The current Montage platform has two SWP70 Standard Wave Processors arranged in a so-called — and somewhat offensively named — master/slave configuration. This tandem has been the mainstay of top-end Yamaha synth and arranger keyboards since the early days of Advanced Wave Memory (AWM). The pair are interconnected by a dedicated, addressable 16-bit data bus (ABUS).

The SWP70 is highly tailored for AWM2 and FM-X synthesis. The tone generation channels are dedicated hardware feeding an internal mixing/effects complex. Digital audio is conveyed on- and off-chip via I2S format serial audio streams. The SWP70 can support up to eight input and eight output I2S streams.

I doubt if this microarchitecture will change much. It seems to be entrenched in the Yamaha engineering DNA. There are two possibilities for improvement.

First, the current Master SWP70 uses only one of its two available WAVE SDRAM memory channels. The WAVE SDRAM is where the SWP70 caches samples fetched from ONFI 4.0 NAND flash waveform memory. The Master SWP70 handles AWM2 synthesis alone. (The second SWP70 handles FM-X synthesis and does not have any wave-related memory.) The unused WAVE SRAM channel is marked “Not Installed” and “For Future Model”. Most likely, the second channel would be used to increase the polyphony spec.

Next, Yamaha could re-spin the SWP70, perhaps producing an SWP71 variant. There is precedent for a re-spin. The Motif ES is based on the SWP50 and its successor, the Motif XS, is based on the SWP51. What Yamaha adds to silicon is anybody’s guess. 😉

ARM host processor

The current Montage host processor runs Linux and has many duties — none of which perform synthesis. The host processor is a Texas Instruments AM3352BZCZ80 processor operating at 800MHz.

The AM3352 Texas Instruments Sitara processor has a spec which is nearly quaint by today’s standards:

  • ARM Cortex-A8 32-bit RISC processor
    • Single core
    • NEON SIMD coprocessor
    • 13-stage superscalar pipeline
  • PowerVR SGX Graphics Accelerator

The modest 800MHz clock lets Yamaha hit the desired power/heat operating point, thereby avoiding active cooling.

The key limitation that catches my eye is “single core”. This means that only one computational thread can run at any given time. Yamaha engineers must positively envy Korg’s use of Raspberry Pi 3 (Broadcom BCM2837):

  • Quad-core ARM Cortex-A53 (ARM V8 ISA)
  • 2 wide issue, in-order pipelines
  • 1.2GHz clock

With RPi3, one gives up superscalar for simpler in-order pipelines, but you do get to run four threads simultaneously.

I’m sure Yamaha engineers have studied newer, available embedded ARM processors for Montage M. Does the “M” stand for multi-core?

Guesses, anyone?

If Montage M goes multi-core, this opens the possibility of software instruments (and effects) running on one or more of the host processor cores. Current Yamaha synths allow expansion through sample libraries only, while competitors support the addition of new engines. Kind of ironic considering that its captive Steinberg developed VST plug-ins in 1996.

Even the lowly Korg NTS-1 supports the development and addition of new oscillator and effect models through the logue SDK (API) and librarian.

So, readers of Yamaha Musicians Forum, does the prospect of software plug-ins get Saul’s pulse racing, again? 🙂

The new choice for host processor and its embedded display controller may also give Montage M a new multi-touch display. Could “M” also stand for “multi-touch”. Using the Montage touch screen as an X-Y pad always seemed like a no-brainer… Then there are new possibilities for multi-touch articulation.

It’s worth noting that the new Montage M platform may leave MODX+ in the dust. I don’t expect much functional trickle-down from Montage M to MODX+. The MODX+ platform is riding the profit-pumping, low-cost technology curve and won’t be able to keep up with its jacked brother.

Random weekend thoughts

Posted on by

A bunch of crazy thoughts after the long holiday weekend…

Yamaha P-S500 price drop

The Yamaha P-S500 is a baby Clavinova Smart Piano (CSP) in the P-series portable digital piano line. The P-S500 has a greatly simplified front panel: ten touch-sensitive control buttons and a 2 line by 16-character display. [Hey, the 1990s called and want their display back!] This user interface parsimony simplifies the overall appearance of the instrument and makes space for the streaming (falling) light display above the keybed. The P-S500 has the CFX piano, of course, and the rather nice Bösendorfer — both enhanced by VRM

Like its CSP brethren, You need the Yamaha Smart Pianist app in order to dig deeper. Once you get below the surface, you’ll find auto-accompaniment and a slew of secondary voices taken from Yamaha’s mid-range arranger keyboards. The S500 voices are roughly equivalent to the PSR-SX600 arranger. Some people trash arrangers, but many of the arranger voices are taken from Motif XF! These voices are much better and cover a wider range of sounds than the recycled string, synth pad, choir, bass and vibraphone in much of the digital piano line. [My only beef with the P-515.]

Why mention any of this? September 1 and new price lists are out. Initially, the P-S500 was offered at $2,000 (MAP). Presto chango, and the new MAP price is $1,600 USD, same as the P-515.

At the new price, I think it’s worth considering as an alternative to the P-515. Unfortunately, the S500 has only the GHS action, losing the rather wonderful, P-515 NWX action. You also give up 5-pin MIDI. Worth a look if these things aren’t important to ya.

Hey, Yamaha!

Wanna sell more P-S500s? Put them in Music & Arts retail stores where people can find them. I have yet to see an P-S500 in the flesh…

While you’re at it, rename the “Smart Pianist Specifications” PDF to something meaningful to a customer. I installed Smart Pianist on my iPad to see see its tricks. Without Smart Pianist being connected to a compatible keyboard, I didn’t get clue one about what it can do. Open “Smart Pianist Specifications,” however, and I see the Smart Pianist features supported by each of the compatible keyboards — quite helpful to a prospective customer who wants to know what Smart Pianist can do.

Yamaha, do real people actually test your keybeds? I can’t imagine inflicting the GHC (P-225) keyboard on beginners. Stop being so secretive and get these things into the hands of real customers! The GHC needs to be fixed, now, before production ramps up. Try before buy, folks, as GHC is not merely an improved GHS.

Finger drum pads

The Yamaha FGDP Finger Drum Pads have dropped (finally). Thanks go to all of the sleuths who uncovered the FGDP trademark and so forth. The FGDP-30 and and FGDP-50 will advertise for $199 USD (USA MAP) and $299, respectively.

Yamaha FGDP-30 and FGDP-50: Recognize that trademark logo?

Yamaha, since the Montage M doesn’t have drum pads, did you test the FGDP-30 and FGDP-50 with Montage M? 🙂

Presence, absence.

I’m not the only person to notice the absence of Montage M leak stories on MusicRadar, Gearnews, and a few of the other big-name Web sites. Yet, there were the FGDPs big as life on MusicRadar this morning.

My guess? They all have Montage M review units and are under NDA. Expect Montage M reviews when the news embargo is lifted on announcement day.

Yamaha P-225 review: It’s not for me

Posted on by

One of the drawbacks of playing high-end instruments is that it is hard to go back to entry- and mid-tier keyboards. Therefore, I’m going to use the Yamaha DGX-670 as my reference point in this review. Comparing the new Yamaha P-225 against DGX-670 is both fair and informative. Both instruments feature the CFX grand, both have VRM Lite and both sell for $750 USD (MAP). I’m going to focus on acoustic piano, electric piano and, to some extent, basic secondary sounds.

The big question in everyone’s mind is the new Grade Hammer Compact (GHC) keybed which helps make the P-225 slim and (lighter) weight. The DGX-670 has the well-known Yamaha Graded Hammer Standard (GHS) keybed. The GHC keys have a solid feel even though they are plastic through and through. No texturing.

The DGX-670 GHS is enjoyable to play. The P-225 GHC is not. In one word, its “work.” GHC has a springy resistance that is felt immediately. The one and only up-side is the ability express dynamics with more ease than the DGX-670 GHS. You can get some relief by increasing the volume slider or, perhaps, by changing the touch response.

My hands are 72 years old and somewhat arthritic. My hands hurt after playing the P-225 for one hour. I spent an hour with the DGX last Saturday with no ill-effect at all; It was downright fun to play it. Not so, the P-225.

Organ, strings and pads are difficult to play on GHC. Forget smooth organ-like playing gestures — GHC makes you dig in. I question whether I would want GHC for MIDI control as legato gestures would be labored.

If you’re buying on-line, please do not assume that GHC is a clone of GHS with a similar touch. Nothing could be farther from the truth. Try before buy. Do not buy a GHC-based keyboard on speculation! (Same goes for the Yamaha P-145 as it, too, has the GHC action.)

The CFX grand is the 225’s featured piano. I preferred the mellower sounding Ballad Grand variation. The front-firing speaker system does not do the CFX sound any favors. The 225 AP sounds thinner than the DGX-670. The DGX, with its upward firing woofer and tweeter, sounds richer than the 225. If you want better sound, expect to add external monitors to your P-225.

The P-225’s electric pianos are typically Yamaha. They are decent enough and do not offend. The string sounds — also typically Yamaha — do offend me and need a serious update. The Synth Pad voice is pleasant and usable. The pipe organs are OK and, like the strings, are Yamaha perennials.

Frankly, I would take DGX-670 over P-225. The sound system is better and the available secondary voices are numerous, varied and quite good. The DGX secondary voices are taken from Yamaha’s arranger series. The P-225 secondary voices are very limited in comparison. The P-225 wins only on portability (size and weight).

If you need a light-weight slab piano, I recommend trying the deprecated P-125 wide-by-side with the P-225. The P-125 is a decent sounding instrument and you may be able to buy one at a reduced price. I suspect that retailers have P-125 inventory to sell through.

Wish I could be more positive, but the P-225 is not for me.

Montage M preseason

Posted on by

Forum folks are picking over the Yamaha Montage M leak photos, so no need to duplicate that here! Wish we spent as much attention on world peace. 🙂

Many comments — my own included — are reading personal hopes and dreams into the new boxen. My own special hope is a decent keybed action for piano practice. I’m seriously looking for a practice digital piano in order to work out arrangements and get ready for Sundays when I need to sit down at the Petrof acoustic grand. That’s why my own guess of “X” for “escapement” is an act of wishful thinking. Dare I hope for Virtual Resonance Modeling?

The time period between leak and reality is much like football preseason. Right now, it’s the perfect season. Your team looks pretty good, no major injuries, and “Superbowl here we come!” Then, like a perennial Browns fan, your hope is slowly extinguished week by week. [Well, that was bleak.]

When I saw Yamaha’s parting gift — the character pianos — I thought, “We’ll be seeing these, again, shortly.” So, I won’t be surprised to find CFX, Bösendorfer, U1 Felt, U1 upright, Nashville C3 and friends in Montage M. Even if the pianos aren’t factory installed, there’s always expansion flash memory. Could I hope for the CK pipe organs? Same answer.

The most striking features in those horribly blurry, low-rez, leak pictures are the textured keys, six new knobs below the main touch screen and a new subdisplay above the bank of eight knobs and eight sliders. The subdisplay is a feature borrowed from Genos. On Genos, it’s called the “Live Control” subdisplay. Instead of fixing internal parameters to TONE, EQ/FX and ARP/Motion FX, the user can assign internal parameters to knob/slider groups and switch between groups in real-time. The subdisplay tracks current parameter values, updates and so forth.

Of course, the big question is “What are the internal engines?” AWM2 and FM-X are givens. Wishes include AN-X and the YC stage tonewheel organ. More engines means more parameters, so that Live Control subdisplay seems like a really good idea™.

The more I contemplate functional details, a larger question arises: “How will Yamaha keep the Montage M, Stage CP and Stage YC in their own lanes?” Yamaha need to make Montage M inviting while keeping the CP and YC specialists special. I think Montage M will follow the Montage line and remain a jack of all trades, integrating multiple engines into motion control, sequencing and studio audio/MIDI channels. Sound designers and players who need a generalist keyboard will still turn to Montage M.

Organists and pianists will turn to Stage YC and Stage CP. The simplified, focused user interfaces have proven successful — little or no menu-diving required. Yamaha have learned a lot after introducing the Stage CPs at January NAMM 2019. [The Stage CP tech is even older; check dates in the manuals.] The Stage YC interface is an improvement on the Stage CP. Hopefully, some of this experience has trickled over to the Montage M.

Which brings me to my concluding question. Even if we see AN-X in Montage M, will we eventually see an AN-X specialist keyboard, a Stage AN? Montage M would need to fit AN-X into its generalist usage model and I don’t think that will satisfy analog purists/players. [How ’bout alternate MPE control, too?] I think there is an open lane for a control-studded Stage AN specialist.
