Want vs. need: Yamaha Seqtrak

It doesn’t cost anything to window shop!

With the holiday selling season in full swing, I took another look at Yamaha Seqtrak. Ya never know when a bargain might present itself, so it’s good to be ready. 🙂

Seqtrak is Yamaha’s low cost alternative to the all-in-one Teenage Engineering OP-1 — a battery-powered synthesizer, sampler and sequencer. The price is much sweeter, $399 USD (MAP/street), than Teenage Engineering.

I’ve been hesitant to chomp on Seqtrak because I don’t really need a groove box. Yeah, it might provide fun occasionally, but it doesn’t really fulfill a need for what I play live (mainly keyboard emulation of acoustic instruments).

A few postings on Yamaha Musicians Forum motivated me to investigate further, however. Seqtrak implements two forms of synthesis: AWM2 and FM. At first, the AWM2 support sounds like a yawner. Guess what? The AWM2 sound set is pretty much the Motif XF (MOXF) factory sounds! That ain’t chopped liver.

The Seqtrak DX FM implementation is the same as the Reface DX. Even though it’s a four-OP implementation, feedback is supported on any OP, yielding a harmonically richer sound than four-OP of yesteryear. Both DX FM and AWM2 synths can be routed into a robust collection of DSP effects, including rotary speaker, VCM effects and HD reverb.

I wish the Seqtrak DX FM editor supported the Reface DX. It is one nice editor.

Thus, $399 buys a three channel (two synth, one DX FM) battery-powered MIDI module supporting DX FM and Motif XF synthesis. That’s quite a bargain when Reface DX alone costs $400 or so on a typical day.

As an expander, my main quibble is usage model. Seqtrak does not have a display showing the currently selected voice. I can’t tolerate that level of uncertainty during a live performance. The Seqtrak app controls all, but it means schlepping another piece (iPad) to the gig and making everything work live.

Still, it’s enticing. A case of want over need.

Seqtrak inside

What’s inside that tiny box? Thanks to a brave soul on LoopyPro, we get the picture.

Seqtrak consists of three printed circuit boards (PCB): a front panel board which runs most of the length of the chassis, a large digital electronics board mounted in parallel with the front panel board, and a small analog electronics board near the battery and speaker. The analog electronics board has connectors for USB-C, PHONES, AUDIO IN and MIDI.

SeqTrak printed circuit boards

The main event is the digital electronics board, usually called “DM” in Yamaha-speak. In this picture, we are looking at the bottom of the board. The top of the board — sometimes called the “component side” — is obviously out of view. The three large rectangular integrated circuits (IC) are SDRAM (e.g., Winbond W9825G6KH-6 256Mbit Parallel 166 MHz, typically organized as 32MBytes). The specially labelled IC is (likely) a Winbond 256Mbit (32MByte) NOR flash ROM containing the Seqtrak code.

The memory ICs surround the foil pattern for a Yamaha proprietary SWX processor. I’m guessing SWX09 or SWX10. SWX combines an ARM core with AWM2 tone generation and DSP effect processors. Seqtrak implements DX FM because only SWP70 implements FM-X. Low cost devices like Seqtrak usually employ a single, highly integrated SWX and do not include a separate SWP70 tone generator.

There may be additional memory devices on the component side of the DM board. The battery is a 3.6V 2100mAh Li-ion battery.

October 8th — How’d that turn out?

Ableton Move

Ableton Move is a new portable, stand-alone “music creation” surface. Move has four tracks (drum, sampler, or synth) and a step sequencer. Move has audio input and output (3.5mm), built-in WiFi, 64GByte internal storage, built-in speaker and microphone, and an OLED screen (128×64 pixels). Control gizmos include 32 pads with polyphonic aftertouch, 9 touch-sensitive endless encoders and 16 multi-function buttons.

Ableton Move

Like its competition (Yamaha SEQTRAK), Move is loaded with 1,500+ preset instruments, samples and drum hits. Three instruments are preloaded: Drift, Wavetable and Drum Sampler (plus Melodic Sampler).

Each track has up to two (insert) effects with two more for the Main Track. Effects include everb, Delay, Saturator, Chorus-Ensemble, Phaser-Flanger, Redux, Channel EQ and Dynamics.

Interesting — to me and other nerds — is the 1.5GHz quad-core ARM Cortex-A72 within. Wisely, Ableton included a USB-A port which means you can hook up your class-compliant controllers to Move. I wish this kind of “HOST” capability was standard everywhere on planet Earth.

Ableton Move is 313.5mm wide, 146.3mm deep, 34mm high. That’s 12.4 inches by 5.8″ for you English types.

Of course, Ableton Live Intro is bundled and Move knows about Ableton Live (and vice versa). With portability and integrated sound-making, I could see the Ableton Move becoming the prefered low-end Ableton Live controller. I have a boatload of mini controllers. At $449 USD, I could see Ableton Move replacing them all, even if I never do the on-the-go beat-making thing.

ROLI Airwave

If you ever wanted a Theremin, maybe a ROLI Airwave?

ROLI Airwave

The ROLI Airwave lets you wave your hands about like The Amazing Kreskin, the mentalist. It connects to ROLI Piano M (formerly known as “Lumi Keys”) or ROLI Seaboard. Airwave supports gestures:

  • Air Raise: Raise your hand up or down.
  • Air Tilt: Turn your hand (rotate your wrist).
  • Air Glide: Move your hand left/right over the keys.
  • Air Slide: Move hands front to back over the keys.
  • Air Flex: Change the angle of your wrist.

Put your hands in the air like you just… Oh, never mind.

The gestural thing is kind of neat. It would be cool to conduct a virtual orchestra, not just play keys. The tech is called “ROLI Vision”: “Airwave uses infrared cameras and ROLI Vision technology to reliably track all 27 joints in each of your hands at 90 frames per second. The data is converted into MIDI in real time, giving you incredibly precise control of your musical expression.”

ROLI Airwave is $299 USD and pre-order is available. And there are bundles.

Connectivity specs:

  • 3.5mm TRS Headphone Output
  • 3.5mm TRS Pedal input
  • Two USB-C ports (data and power) plus a magnetic USB port for ROLI hardware
  • Class compliant MIDI over USB and class compliant audio interface

Reface DX: No static at all

If you’ve browsed Yamaha Reface at on-line retailers, you’ll know that Reface DX and Reface CS are currently on sale. The DX and CS are the two Katzenhammer kids which share the same internal design, using a Yamaha-proprietary SSP-2 processor as the central compute engine.

The Reface DX price is startling: $250 USD (MAP). Wow! That’s the price of a mid-range guitar pedal. Makes me wonder if the DX and CS are being closed out or if Mark 2 models are in the works. The venerable SSP-2 is supplanted by the SSP-3 and perhaps the inventory of SSP-2 is depleted.

The Reface CP and Reface YC MAP prices remain the same. I suspect that sales of these models remain solid as there always seems to be a need for good EP and organ sounds.

That DX price is a clearance price. When Reface was released, I vowed to buy at blow-out pricing. Yep, I put a Reface DX on order.

A few Reface DX programming links

First off, I’m amazed at the number of contributed DX patches at Yamaha’s Soundmondo sharing site. There are literally thousands of Reface DX patches. The Soundmondo tagging idea is good, but too many punters over-tagged their submissions. I’m looking for “orchestral” sounds and there are many tagged patches that are not remotely “orchestral”. A search system is only as good as the quality of its tagging.

If that’s not enough patches for you, try the Reface DX Legacy Project. Martin Tarenskeen maintains this vast library of Reface DX patches converted from old FM machines. I can’t vouch for the quality of the conversions (yet), but I’ll be heading there for old 4-op DX21 patches. I had a DX21 back in the day, and know the factory sound set quite well. I still have the original cassette tape with DX21 patches on it!

I also plan to do a little FM programming. This series of articles by Manny Fernandez is excellent:

Learn from the best in the field — that would be Manny. His articles have links to his example patches in the Soundmondo library.

You’ll need a Reface DX algorithms and envelope cheat-sheet (PDF), too.

Reface DX is old enough to be a grown up by now. So, there’s plenty of on-line support if you choose to jump into the Reface DX pool.

Yamaha SEQTRAK FM

I was curious to see how SEQTRAK FM stacks up against Reface DX. My conclusion — it’s the same FM engine:

  • 4-op, 12 algorithms, polyphony 8
  • Same algorithms and parameters
  • SEQTRAK includes many Reface DX patches

Looking beyond FM, SEQTRAK does AWM2, sampling and sequencing, and offers more effects. I’m more of a player than a button-pusher, so Reface DX is better for my personal needs.

Reflecting on the SEQTRAK FM and AWM2, I would expect to find a Yamaha proprietary SWX09 at its heart. The SWX09 core executes the Renesas SH architecture, same as SSP. Plus, SWX09 has an integrated AWM2 tone generation engine.

Yamaha SEQTRAK: Quick reaction

I’ve already gotten requests to comment on the new Yamaha SEQTRAK™ Ideastation. Mind you, I haven’t touched one, but here goes.

How does SEQTRAK compare to the old QY-70/QY-100? I would say, they are different beasts for different compositional processes. The QYs are the early predecessors of the Motif and PSR, Tyros, Genos sequencers. The QY usage model is based on phrase-oriented composition providing a big internal library of musical phrases. The QYs assembled the phrases into arranger-like styles. Then, one composes songs using either a preset or user style.

The QY workflow is pretty conventional. Motif and PSR people would recognize the line-oriented presentation of sequencer data and the infamous “JOBS” for tasks like quantization, copying sequence data and so on. The Motif series and arranger workstations borrowed heavily from the QYs. In fact, sometimes, I feel like they are running the old legacy code!

I like my QY-70 because I can compose songs in the “traditional way”. The QY beats both Motif and PSR/Genos in the way it handles chord tracks. Oh, how I wish for that in today’s instruments. The QY designers were on to something good, there.

SEQTRAK is Yamaha’s attempt to capture some of the old RM1x and RS-7000 groove box magic. The old groove boxes are in step with modern beat-box sequencers. The workflow is pattern-based — create a pattern in a track, create another pattern in a different concurrent track, and chain the concurrent patterns into a song. (Yeah, this is a gross over-simplification. 🙂 ) This is different compositional process than the QYs which are more “trad”.

Japan’s Lost Decade(s) hit Yamaha hard and made their managers very conservative. The old QYs and groove boxes got the ax in order to survive a moribund Japanese economy.

I think Yamaha got tired of watching other people make money on tech which they pretty much invented back in the 90s and 00s. Teenage Engineering is making outrageous money with the all-in-one OP-1. $2,000 USD (MAP)? Really?

In my quick opinion, SEQTRAK is too timid, too conservative. Yamaha went to the AWM2 and FX technology well One. More. Time. The only upside is the low selling price of $399 USD (MAP). Given the polyphony spec, I would expect to find a single SWP70 (AWM2+FM) tone generator IC and an ARM host processor. How innovative is that? Where is AN-X or even the low-spec AN found in Reface CS?

Is SEQTRAK competitive with OP-1? Time and deep analysis will tell. In the meantime, I see SEQTRAK aimed at the $400 to $500 synth plus sequencer groove box niche. Strap a few KORG Volcas together and you get SEQTRAK — for roughly the same price. I’m thinking Volca Sampler 2, plus Volca FM 2, plus Volca Keys? Take your pick. The Roland Aira Compact series come to mind, too. The SEQTRAK app one-ups KORG (and Roland), however, and SEQTRAK has superior connectivity. Engine-wise, it’s all rather plain Jane.

Hmmm. I still have my Yamaha AN-200. Aside from FM and sampling, would SEQTRAK give me more? SEQTRAK versus the old AN-200 and DX-200 would be a better comparison than QY.

I also question Yamaha’s time-to-market with SEQTRAK. Yamaha needed to extend the trademark’s intention to use (application) multiple times. This tells me that they had trouble finishing and releasing this product on schedule. I’m sure Web comments will trash Yamaha for too little, too late.

As someone steeped and experienced in American high-tech culture, Yamaha engineering needs to have its butt kicked. Hard.

Update: Observations

The Yamaha SEQTRAK specifications state preset waveform memory at 800MBytes, when converted to 16-bit linear format. With a 2-to-1 compression ratio, physical preset waveform memory is about 400MBytes. User waveform memory is 500MBytes, uncompressed presumably. Overall physical waveform memory is around 1GByte.

I quickly browsed the voice and FX lists. SEQTRAK has a slew of drum sounds as you might expect. The AWM2 and FM voices will look very familiar to Montage/MODX players. The keyboard voices are reminiscent of Motif XS; these are not fresh sounds. In fact, if one owns a Montage or MODX, I don’t see the need for SEQTRAK unless you really dig its portability and workflow.

The FX section is a whole lot better. Yamaha included many of its latest “EDM-oriented” FX like spiralizer, multiband compressor (3-band), Uni Comp compressor, bit crusher, digital turntable, wave folder, etc. Bread and butter FX include the current crop of amp sims, VCM effects, and REV-X, SPX, HD reverbs. Yamaha did a good job here.

SEQTRAK has many function buttons on its side panels.

  • Left side: volume up/down, delete, mute, solo, page, play
  • Rear: bar length, octave, scale, key, record sample, undo/redo, clear FX
  • Front: sound design page, FX page
  • Right: BPM up/down, swing, project

That’s a lot of special purpose buttons to remember. Fortunately, the printed legends are clear. (I prefer the orange/grey model for that reason.) External connections are made on the right end panel: phones, audio IN, MIDI, and USB-C.

The big list of parameters and modes is the “Index”, which replaces any kind of LCD or OLED screen. Yamaha saved money here. A “global meter” is right next to the index showing parameter values and load/save status. The meter indicates key scale (minor, major, etc.) and root key. You’ll need a cheat sheet nearby to know what’s selected.

You can select a sampling source (MIC, audio IN, USB, resampling) and assign incoming samples to the synth keys for playback. Sampling does auto-normalization (if configured), but there’s not much else for sample editing in the native hardware. I didn’t see any ability to assign a sample across the synth keys.

The sound design section lets you adjust the most common, basic parameters: pan, volume, AEG attack (decay/release), filter cutoff and resonance, FX sends, etc. Look to the SEQTRAK app for deep editing.

I noticed that some functions in the SEQTRAK User Guide are marked “[OS V1.10]”. A reasonable inference is that SEQTRAK got a major functional update during its long gestation period.

NAMM 2024: Yamaha SEQTRAK Ideastation

Remember, folks, you saw it here first in October 2023. 🙂

As I mentioned way back when, Yamaha SEQTRAK™ comes in two color schemes: black and orange/grey. Yamaha did a decent job on the price: $599 USD (MSRP) and $399 USD (MAP). It’s available for pre-order at on-line retailers.

The front panel is divided into three sections: Drums (left), synth and sampler (middle) and sound design/effects (left). (Click image to zoom in.)

The Interwebs are absolutely plastered with Yamaha SEQTRAK news, so there isn’t any need for a long screed. Just the facts:

  • Four track types: Dum, synth, DX and sampler
  • Eleven tracks: 7 Drum, 2 AWM2 synth, 1 FM synth, 1 sampler track
  • Eight (8) projects
  • 128 sequencer steps
  • Two AWM2 synth engines (128-note polyphony total)
  • One 4-op FM synth engine (polyphony: 8)
  • 2,032 preset voices
  • Built-in sampler (44.1kHz, 16-bit)
  • A/D input (stereo 3.5mm mini jack)
  • Built-in speaker (1W 2.3cm) and microphone (MEMS)
  • AUX audio IN (3.5mm mini jack)
  • USB-C power MIDI to host, MIDI to device, and audio
  • Bluetooth MIDI and Wi-Fi (for big data like WAV)
  • Headphone output (stereo mini jack)
  • MIDI IN/OUT using the included converter cable
  • Internal rechargeable Li-Ion battery (estimated life: 3-4 hours)
  • 13.5″W x 3.8″D x 1.5″H, 1.1 pounds (0.5kg)

SEQTRAK is positioned as an anyplace, anywhere, all-in-one music-making production tool. Yamaha are calling it the “Mobile Music Ideastation”. It is supported by the SEQTRAK app which adds more functions: Visualizer (visual effects), hands-on tutorial and so forth. Detailed sound-editing depends upon the app.

Wonder if they will trademark “Ideastation”?

Here is the SEQTRAK Walkthrough video. In the end, it comes down to workflow and sound. I don’t think Yamaha are breaking new ground with AWM2 and FM, tho’. Kinda tame.

For once, Yamaha got smart and announced a major product just before NAMM. (NAMM 2024 starts Thursday, January 25, 2024). Maybe the early announcement will overcome the big yawn of Prince’s purple piano and flagging NAMM attendance?

Oh, yeah, here’s the spy photo one more time…

Montage M (emulated)

Thanks, again, to Saul at Yamaha Musicians Forum. Quoting:

Yamaha has created a software version of the Montage M. This is a 1:1 emulation with all features present.
My understanding is that the software will come free with the purchase of a new Montage M but that it will also be available as a standalone purchase.

Of course, this raises many questions about capabilities, end user licensing, distribution, pricing, yada-yada. We’ll know soon. BTW, only n00bs launch a new product on a Monday. 🙂

Back in April, Steinberg announced a “rent-to-own” partnership with Splice. Could the new partnership bring the emulated Montage into fruition?

Will the emulated Montage M interoperate with Yamaha’s new control surface?

Flash: Major leakage

A few highlights from the Hispasonic article.

The Expanded Softsynth Plugin (E.S.P.) provides an “in the box” version of Montage M. Available in January (at no cost to Montage M users), E.S.P. provides hardware and software integration (editing, use of sounds, etc.)

AN-X polyphony is 16 voices (as rumored). The basic voice architecture includes 3 oscillators, noise source, double filter section, ring and FM modulation, autosync, PWM, 2/4-voice unison modes.

Each AWM2 part of a performance can stack up to 128 elements. AWM2 polyphony is doubled. The 8-part limit on Seamless Sound Switching (SSS) remains.

Montage M factory AWM2 preset sounds (7,620 multi-samples) occupy 10GB of memory when converted to 16-bit linear format. USER flash memory space is 3.7GB (presumably uncompressed). The article refers to an additional 128 voice polyphony when playing from USER flash memory — which is similar to Genos (gen 1).

FM-X polyphony remains 128.

Yamaha Pure Analog Circuit (PAC) is improved with better mids and bass.

As rumored, only the M8x model gets polyphonic aftertouch. The M6 and M7 have channel aftertouch. (Probably FSX keybeds as before.)

Overall, the Hispasonic article repeats, confirms or amplifies the most recent leak. I’m still waiting to see the manuals, especially the Data List PDF. The analog cultists hate everything already.

A few other random comments. A separate leak claims “VCM Rotary Speaker effect and realistic drawbar behavior deliver authentic organ control and sound.” Well, as far as eight sliders will take you, anyway. I think this means flipping the slider behavior. Maybe Yamaha ported the Stage YC rotary speaker effect to Montage M? That would be welcome on both Montage M and Genos (mark 2).

Wonder where all the preset waveform memory went? The “Best of Montage M” screen lists four pianos: CFX Concert, Ballad Piano, Hamburg Grand and Imperial. Pianos notoriously chew through sample memory.

The pictures aren’t up to Yamaha PR quality (resolution). Seem kind of home-brew. That carpet is hideous. I tore out one like it from our first house — 30 years ago. 🙂

The fair, the Princess and the unicorn

Yamaha at Synthfest UK 2023

Yamaha have issued the following statement regarding their participation at Synthfest UK 2023 this weekend:

“Yamaha are looking forward to joining SynthFest UK this weekend to display a wide range of hands-on products along with Yamaha specialist staff to support any enquiries.

We will be exhibiting our recent releases including the CK Stage Keyboard Series and Finger Drum Pads, in addition to our more established MODX+, CP, YC and Reface ranges.

There has been much speculation regarding the launch of our successor to the flagship Montage synth which has been announced as an October release. To manage any expectations ahead of the show, we would like to clarify that unfortunately the timing of this new release means that it will not be featured at the show.

We look forward to seeing you all there.”

I couldn’t possibly comment. 🙂

The other unicorn in the room

With discussion focused on the upcoming Yamaha Montage M, we’ve forgotten about the other unicorn in the room: Yamaha SEQTRAKâ„¢.

It’s a Yamaha trademark

Before I add anything new, here’s a brief review of what we know from the public record. As many others have cited, “SEQTRAK” is a trademark registered by Yamaha. The “SEQTRAK” character mark is registered with both the United States Patent and Trademark Office (USPTO) and the European Union Intellectual Property Office (EUIPO). None of this should be surprising.

The USPTO trademark process has two major steps: intent to use and statement of use. The initial filing data — intent to use — was filed October 20, 2020. An applicant (Yamaha) must eventually file a Statement Of Use (SOU) when the mark is placed into actual use, i.e., the trademarked product is available for sale. If an applicant doesn’t file a timely SOU, they must apply for an SOU extension. As to “SEQTRAK”, Yamaha filed for and received its fourth extension on April 13, 2023.

Given the pandemic, supply chain issues, etc., SEQTRAK has been delayed. There may be technical reasons, but we don’t know that.

It’s got class

A trademark is valid only within a specific field of goods and services. “SEQTRAK” is valid within the following clases:

  • Primary class: 009 Electrical and Scientific Apparatus; US Classes: 0021, 023, 026, 036, 038
  • Primary class: 015 Musical Instruments; US Classes: 002, 021, 036

Breaking this down into English, we get the following uses under Class 009:

  • audio amplifiers;
  • audio mixers;
  • electric and electronic effects units for musical instruments;
  • sampling units, namely, digital phrase samplers used to record, replay, and edit digitally stored music samples;
  • music synthesizers, namely, desk top control units used to synthesize music that do not function independently as musical instruments;
  • electronic tone generators for musical instruments and audio effect processors;
  • electronic music sequencers;
  • electronic rhythm programmers;
  • downloadable computer software for generating, reproducing, effecting, and recording sound;
  • downloadable computer software for arranging, sequencing music;
  • downloadable computer software for creating computer music.

For class 015, Yamaha state:

  • electronic musical instruments;
  • electronic music synthesizer;
  • electronic drum machines;
  • electronic percussion instruments;
  • electronic rhythm machines.

Well, that really narrowed things down, didn’t it? Not. 🙂

Standing back, however, one gets the impression (gestalt) that SEQTRAK is a piece of hardware (like a sophisticated synth/beatbox) which integrates with downloadable software for sequencing. The software part kind of sounds like Steinberg Cubase, Groove Agent, Halion, etc.

What’s new?

First, I am not going to reveal sources and methods, and neither should you. The “SEQTRAK” name appeared in the warranty list spill to which Yamaha put a quick end. Zip it, Scott.

I’ve seen SEQTRAK described as a “music production studio”. Yamaha have used the term “music production studio” in the past. The most relevant past use is the venerable Yamaha RS7000 Music Production Studio. The Yamaha RS7000 is a groovebox combining a sequencer, sampler, synth, digital effects and mastering tools.

The RS7000 is the beast from 2001. [The year, Not the film.] Yamaha haven’t played in this space since then. They are due.

We know from the earlier reveal that there are two SEQTRAK models. Both models are functionally the same; you get a choice of black or orange livery. Physically, SEQTRAK is about 13.5″ wide, 3.8″ deep, 1.5″ high. That’s roughly the size of a small QWERTY keyboard. Connectivity is USB-C and Wi-Fi. Wired connections are made through one of the side panels. SEQTRAK is intended for desktop use, maybe in front of a QWERTY keyboard or laptop.

Let’s imagine an attractive, modern-looking desktop control surface. The surface is divided into five panels:

  • Sequencing (8 knobs, 16 buttons)
  • Mixing (4 knobs, 8 buttons)
  • Status (back-lit legends and LEDs)
  • Effects (4 knobs)
  • Output (master volume knob and built-in speaker)

On-board, one expects a synthesizer — oh, what the heck, make that two synthesizers — and a sampler.

Questions

Two big questions loom in my mind. First, what is the assignment of music production activies (synthesis, editing, ya-ya) to hardware and software? Is synthesis built in or is synthesis performed by Halion, for example? Second, does SEQTRAK integrate with other hardware products like Montage M and the new FGDP-50 finger drum? Please recall, FGDP-50 does not have standard MIDI IN/OUT and seems a little lonesome by itself. The FGDP-50 would be a natural companion for a groovebox. Is Montage M part of the “music production studio”?

Yamaha have been very, very busy…
