Micro Tonal midi cv converter, quantizer, editor
MUFF WIGGLER Forum Index -> Modular Synth General Discussion  
Author Micro Tonal midi cv converter, quantizer, editor

tubbutec

Hi,

current status of this module:
- Software almost finished
- Second hardware prototype with larger display will be assembled next week, front panels powder coated and screen printed. If everything fits and works we will produce the first batch.
µTune will be presented at Superbooth17



I tried to write down all the features currently implemented. This is a very rough list, if anything is unclear please let me know:
----------------------------

µTune is a tool designed to serve all needs that may arise when dealing with microtonal scales in a modular context.
Is is:

- A two-channel microtonal midi interface
- A two channel microtonal quantizer/mapper
- A Scale editor
- More than the sum of these parts

Its inputs and outputs can be freely configured to various functions. It can also detect when an input is plugged in and change its behaviour accordingly.
Here is a very quickly written overview of its current features:

Quantizer / Mapper
- CV inputs adjustable to custom V/Octave
- Inputs can map to scale degrees, transpose or shift a scale
- High precission CV outputs
- Quantizer can run in continous mode, gated or triggered

Midi to CV interface
- Midi from DIN midi or USB midi
- Dual Monophonic and 2 different Duophonic modes possible

Scale editor
- Any number of notes per scale
- For each note edit: cents, fraction or select from a list of common intervals
- scales not based on the octave are possible
- quickly generate EDO scales
- deactivate certain notes in a scale
- save and load scales on SD card in scl format

VCO calibration
- Easily calibrate any VCO using built in tuner
- 10 point calibration of pitch
- save and load calibration data on SD card

CV to midi interface
- microtonal 2-channel cv/gate to midi interface
- uses midi pitch bend commands to generate microtonal pitch

MIDI router
- a powerful midi router and merger
- route notes / clock and sysex independently
- have a usb midi interface independently from quantizer for example

Firmware update from SD card
Pretty strait forward. Put update file on card, update, ready to go.
If you know Tubbutec, you now that feature updates will be released frequently.

IO functions
CV out: microtonal pitch, velocity chan1, velocity chan 1/2, after touch chan 1/2
Gate out: Midi gate, midi clock, midi start/stop, pass from input
CV in: map to pitch, transpose chan 1/2, shift scale chan 1/2
Gate in: trigger mapping, gate mapping, measure frequency, trigger random transpose chan 1/2

Technical data
- runs on +-12V and/or +-15V
- 16Bit DAC for high resolution of ~1.5mV or 0.2cents
- Input / output 0..10V (10 octaves)
- Hysteresis technology at CV input for stable input note recognition.
- Gates: 0V/5V output, Input 0..15V (High at about 1.5V)
- 1.3'' 128x64 OLED display

Planned features
- Automatic VCO calibration
- Live pitch matching using closed loop approach
- Support KBM keyboard mapping files
- Midi to microtonal midi conversion
- Send/ Receive midi tuning dumps
- Switch tunings via trigger in
- Shift scale root via midi
- .. more

Extensions
µTune features an extension port and we are planning
- Two more channels for a total of 4
- An oscillator extension with perfectly pitched OSCs

here are a few display screenshots. The actual graphics may change until the release version...

Main Menu:


File browser with scale preview


Scale editor - you can edit cents, fractions and select from a list of common intervals


Input / Output configuration for channel 1:


Midi routing


Manual VCO calibration


Configuration menu


There are many more pages and features....

original post:
Hi,

while developing micro tonal updates for the Juno-6 / 60 and SH-101, I started to wonder if some of these features might be interesting for the modular community.

I would like to know if you would be interested in a module with the following features:

- High resolution microtonal midi2cv/gate interface, 10 octaves
- microtonal quantizer, CV in 1V/oct converted to any scale
- Upload scales via Scala or use scl. files directly from a SD card
- Includes a scale editor: Create your own custom scales without needing an external computer.

Looking forward to hear your opinions and suggestions.

oootini

sounds amazing!


StringEmil

Sounds really cool!
Stupid question: Would it be able to do non-microtonal stuff as well for more 'normal' use?

of course. after all, well tempered tuning is just a sub-set of the whole micro tonal space wink


slow_riot

This was a feature I've been hoping to implement in my designs. For all the blue sky thinking of "West Coast" Don Buchla, Serge, Wiard, etc. None of them has left 12tET. (No, unquantized does not mean microtonal). I found a more "hacky" way to get non 12-tET intervals, as I don't have the talent/resources to do a full featured implementation with a PIC like this. But, all credit to you, this sounds *amazing* !

Practically, you should think about creating a PCB that was format independent (i.e. +/12 or +/-15V operation), multiple faceplates for euro/frac/5U etc. As personally I don't think that many modular users will be climbing over each other to use microtones.

Another thing worth thinking about is the (in)accuracy inherent in many VCOs, e.g. the 1% (or greater) losses through common 1k/100k output/input impedences, passive tempcos, and temperature variance in Zener diodes or OTAs in VCO cores. All of these may mean that some analogue designs are simply unsuitable for very intricate microtonal programming.


Mood Organ

Yes, and I'm not the only one.

Sounds quite interesting!


mmelnick

Yes, please


krm

I've developed a MIDI-CV-Arpeggiator module that allows arbitrary microtonal scales (in addition to the standard 12TET).

The basic idea is that you individually tune each of the 'semitones' in the 5 octave range, and the module will interpolate between each of the notes using either a linear or exponential curve (you can choose which one).

Normally you would keep the module in 1v/oct or Hz/volt mode (12TET), but you can switch between the 'normal' tuning curves and the custom one via the front panel of the module.

I'm very much interested in such a module.


tubbutec

Thanks a lot for your opinions and suggestions.

One further question: How many CV channels would you need? 1,2,4?
You could always chain multiple modules for more channels.
Obviously the price would increase the more channels are included..

thx


Phil999

for me, only one channel.


drehleierguy

sounds very interesting indeed! have a look at what Jeff Snyder is doing with his upcoming MantaMate module. it's focussed on the Manta, but will (i think) work as a usb host for all kinds of controllers and will have extensive microtonal functions.

he sent me some more details in a private message - i'll check to see if it's OK if i post here.

www.snyderphonics.com has very little info, but i think there's a bit more on his fb page.

please keep us in the loop!

cheers.

tubbutec wrote:

I'd suggest 1 or at most 2 channels. I second the recommendation of making a format-agnostic design.


calaveras

since my brain thinks in intervals, not chords, I'm most interested in a 2 channel device.
I certainly hear the skepticism regarding OSC accuracy.
But I'd love to find out for myself how 'bad' my oscs are.

It'd be nice if such a module came with a few default scales to start off.
Say TTET, Just, Pythagorean etc just as plain vanilla benchmarks and maybe a few non-twelve tone scales to give entry into microtonalism.
I'm thinking if they were based on Harry Partch or Wendy Carlos' work that could help generate interest.


Mood Organ

Re-reading the original post reminded me that the module has its own scale editing built in. I'm curious how that will be implemented. If the module is big or complex enough (in terms of buttons and screen), it might be worth thinking about more than 2 channels of output.

Alternatively, I can imagine a simple version that just reads Scala files from SD card and does 1 or perhaps 2 channels of CV.

Partch and Carlos are the biggest nutters out there for tuning! They developed their own tuning systems after lifetimes of research, and anything short of mastery is not enough to find the beauty in the beast.

e.g.

http://www.wendycarlos.com/resources/pitch.html

But, I agree with the sentiment. A good bank would be a necessity for those of us just getting started. Although, putting in some presets will be by far the easiest task in the design process. Again to the OP, congrats! I've been waiting for something like this for a long time.

Of course they were, but for a lot of folks that are just getting into alternate tuning/microtonic scales those are recognizable names.
I was actually going to go look up something more reasonable, like a Balinese metalophone microtonal scale, or something from the East Indian quarter tone musical tradition. But in modular circles Partch and Carlos probably have more name recognition.
Besides, there are thousands of East Indian quarter tone scales, and the same I believe can be said for gamelans, with scales being similar, but differing from village to village. So again you might end up with dozens or hundreds of scales just to be definitive.
Those two could probably be micro SD cards unto themselves!
I gotta say after experimenting with some look up tables I calculated and a voltmeter, nah I'm all for a quantizer that does the heavy lifting.


tubbutec

Hi!

thank you all!

Now working on this module, it will have two channels and be chainable to add more channels if needed.

Quote:

There will be a small screen, a rotary encoder and button.

At the moment, there is only a very rough sketch of how it will look like, but will keep you updated as I am developing..


Phil999

great! I think two channels are a wise decision so we can - as calaveras pointed out - have instant intervals.

I look forward for next year to have a good tuning solution in a module. The other approaches with MIDI/pitchbend or VCO sync are too limiting.


calaveras

Cool!
I realy do think this is a piece of the modular puzzle that has been missing.
Down with TTET! you kids get off my lawn


loydb

Also interested.

Phil999

with the Scala application and this future module you should theoretically be able to have any tuning you want with as many notes per octave you want.

For those who don't know, there's an app for iOS called 'Wilsonic'.


GGW

I'm looking forward to what you come up with. One channel would be fine but two will be interesting.
For myself, I just want to be able to offset the notes of the standard 12tet octave. It should be able to do this, separate from requiring scala files. Unless I'm really missing something, scala is based on the starting root note still being "C" of 12tet tuning and the other notes being offset from there. To change that root, the tuning needs to be offset and the other notes recalculated to bring them back to their original value.

Hi if I understand you correctly, you are describing a 'transpose' feature, which will be implemented, but can also be realized with a simple adder.

Scala can do this too, you can choose a different base note when uploading.

Scala describes scales based on the distance to 'C', but it is really just a notation, not a limitation in functionality.

The finished product will be able to map an input note (via midi or CV) to any output voltage. the don't even have to be in ascending order...

Excellent, I thought it would be greedy to ask for 4 channels but chainable sounds like a good compromise.


Villarceau

would be awesome


Arders Bergdahl

I would be very exited if the module would support scales that are not built on octaves.. Like Bohlen- pierce
Also look at the great app Scalegen if you can support all type of scales that Scalegen can support you are quite complete.. It would entail mapping EVERY note to a cv ... Probably

CAD work for 3HE version finished, PCB is at 30%. This is roughly how it will look like:

sopresada

yeah seriously, seriously interested in this.

+1 for banana format please!


Phil999

looks good. So it is also a two-channel MIDI-CV converter. With USB and DIN MIDI. Very versatile and useful.

I think this module could also attract musicians and composers who aren't that much into electronic music yet.


microtonal

Here are some microtonal quantizer suggestions I posted on another recent thread. It seems your device will have most of these features.

An important distinction for CV based quantizing over MIDI is the ability to support more than 128 notes per scale. So if the range is 10V, and the scale is 31 notes, then 311 notes should be quantized in that range.

Microtonal Quantizer desirable features:
* SD card interface to load scala scales while having them resident on the modular
* Text or graphic display to display file names, scale, note and tuning details
* High resolution true 14-16 bit DAC, not an audio DAC
* 1 cent or better accuracy
* >50 notes per tuning scale
* User settable tuning repeat for non-octave scales (the last two features enable modular to break the 128 note MIDI limit)
* Integrated transposition to adjust VCO/VCF ratios with the quantized scale
* Real time transposition and tuning selection


tubbutec

yes, pretty much all these features (and some more) are either planned or already implemented smile

About the 'more than 128 notes topic'

When playing over midi, it will be possible to transpose (for example using the CV IN)

It will also be possible to set the number of notes/volt at the CV in, so lot more that 128 notes are possible.

accuracy is about 0.2cents

Do you need gate in AND gate out? You only use 1 at a time, right? Could be 1 jack and a switch?

Mood Organ wrote:

I think both are needed at the same time. You go in with one or two standard CV-gate pairs and out comes the re-tuned CV-gate pairs, so you can use it without USB or MIDI at all.

Why would the gate out be different than the gate in?

http://www.modcan.com/amodules/quantizer.html

2 modes:
* gate in (gate tells the quantizer when to sample the CV in)
* gate out (quantizer is always sampling CV in; fire a gate when CV moves from one quantized value to another)


tubbutec

Hi, the gate in can be used for the following functions:

- sampling gate
- sampling trigger
- potentially some other functions, such as randomly trigger a note etc...

the gate output:

- gate from midi cv / gate
- output midi clock with adjustable divider
- ....

additionally both gate in and cv can detect if a jack is plugged in. This is used to switch between the various modes.

if for example nothing is plugged into 'gate in', the quantizer is put into continuous mode. if nothing is plugged into cv in, the module will default to midi in.. and so on. The behaviour is of course configurable.

so
A: it makes sense to use both at the same time
B: it is much more convenient to have dedicated sockets
C: a switch takes as much space, if not more on the panel

To tubbutec: nice options. Really looking forward for this module.

I think this and the ES-8 are the only modules left I really need.


tubbutec

Little update: Prototype PCBs are ordered, software development can begin. This will certainly be the largest part of this project given all the features.


Timmy

This sounds like a great module which should satisfy all microtonal needs.

Just for the sake of completeness, it is worth mentioning that the Mutable Instruments Yarns MIDI-to-CV module supports microtonal tunings and Scala scale files transmitted to it over MIDI, and even provides an online Scala editor - see "Tuning systems" at http://mutable-instruments.net/modules/yarns/manual

Of course, Yarns is only MIDI-to-CV, it doesn't do quantisation, but it is very accurate (16-bit DAC, better than 1mV resolution). It's also open-source so the firmware can be modified, and the hardware design adapted to other, non-eurorack formats if required.

There's also Ornament & Crime (disclaimer: I am a co-developer of the firmware for it), which offers, amongst other things, a 4 channel quantiser mode which supports microtonal tunings - both built-in scales/tunings and 4 user-editable scales with up to 16 microtonal semitones per octave. It is also 16-bit accurate with better than 1mV resolution, and is also open-source, so both the firmware (including the included scales/tunings) and hardware is available for modification and/or adaptation to other formats (someone did a dual Buchla format version of it). However, it doesn't support MIDI or SD cards, nor Scala scales. See https://github.com/mxmxmx/O_C and firmware documentation at https://github.com/mxmxmx/O_C/wiki/Ornaments-and-Crimes-extended-firmw are


tubbutec

Hi,

again an update:

been working on this for the last months, picture shows a version I had a few Months back. Final version will have a larger display.

Lot of the features have been implemented already, all the basic stuff is already working:

Midi in out, quantizer, gates, various modes, usb, the editor, loading and saving scales etc..

Working very smoothly and it's a lot of fun already..

Still some way to go to go, but hoping the Eurorack version will be available in April, the 5HE version a bit later.

By 5HE are you talking 5U MOTM or MU format?


aaooaa

Watching this thread because I'll definitely be picking one up once it's done. I've been waiting for something like this for years.


Bojmir Raj Raj

I was just about to start a thread requesting basically exactly what you describe!

Now that I'm fully recovered from a massive stroke, complete with near-death out-of-body experiences and all that shamanistic stuff, it dawns on me that it's high time I join the ranks of financial ruin and lonesome onanism with a modular system, and what's been holding me back, since I don't work in 12tet, is just such a microtonal tuning system!

I assume it'll be available in different formats- Eurorack for me as I already have a handful of Doepfer modules for noise shows, and euro seems to be the format of choice for clones of the old Soviet stuff I love so much!


Gary Dad

applause
I am so buying this.


methodius

exactly what i've been looking for.... thumbs up


freq_divider

Great work! Like many others on this thread, i've been waiting for this one for a long time. Count me in!


Bojmir Raj Raj

Servus Tubbutec!

Say, I hope it's okay to do a feature request here- could you do a cv output for velocity, if you haven't already done that? Something I discovered, having done microtonal music for years, is that the more "feely" and "organic" the instruments you use, the better your chances that people will hear the music as deliberate and interesting, rather than just wonky or weird, and dynamics are a huge part of that.


teknobryan

looks awesome. I'll be looking for it when it's released


thresholdpeople

Fantastic! Watching with interest.

Any chance this'll be available as PCBs or a kit and not a complete module? I'd like to build it into something I'm working on.


methodius

Feature request:

Dunno what you call it ... but in Nord Modular G2 I have this function on quantizer to evenly distribute the chances of hitting a certain note ... So for example if I chose C F F# G notes only per octave - all notes would have equal chance of hitting them ... If there is no 'equal distribution of chance'/octave hitting F# with CV would be much harder than C F or G because F# is so close to F and G.

Hopefully you understand what I mean.

I always found that feature very useful, to equally distribute the chances of hitting the notes I want...Would be even more useful I imagine in a microtonal quantizer.

Yes, absolutely this. I rarely hear anyone talk about it, but it's hugely helpful if you're doing generative / stochastic music. You really want to treat the notes as a set of equals, not as voltage regions of differing size.

This automatic VCO calibration sounds pretty great; have been thinking that there are no Quantizers with this feature for a while!

I wish it would be minus the midi/USB input but with 4 channels!

And maybe some ASR type function if there is a wish to be flashy (:

But am definitely on board for this with the first run.


justintonation

This sounds awesome. I will definitely be getting one.

Also since this is also a midi to cv module perhaps it should also be able to switch scales using the midi tuning standard. This would enable it to be controlled by tall kite's alt.tuner program which allows adaptive tuning (single note tuning) see here:
http://www.tallkite.com/alt-tuner.html

Here is more information regarding the midi tuning standard

Hey,
Any updates on how the build is going and when it will become available? I'm super excited about this one, and am eager to plan it in to the system smile


tubbutec

Here is a progress report:

Most functions of the module are working well, but since there will be a lot of functionality implemented, there is still a lot to do.
We will have a new hardware prototype with a larger display and a few corrections ready for mid-April.
After this, the first production run of the hardware will be produced, which may take another month.

Of course we hope software will be finished soon and we can ship the µTune. But on the other hand it is of greatest importance to ship a finished product with a great set of features.
Thanks for waiting and I hope you won't be disappointed.

Here is the final panel design:

this project looks rad!

It's about time. I know another wiggler, John Nobel, has been working on his own scala micro quantizer with trigger i/o but he has never really thought about making it commercially available.

Will you be the first to make a scala uTuning quantizer in euro? I guess O&C might do it with the newer firmwares but I haven't looked into it.

I have to ask, why the midi i/o? Seems handy i guess - especially if it's simply a bonus feature of the platform you're using. I would have assumed you would have left the midi-cv stuff to the many other modules out there already from doepfer, MI etc. Not for shame. It's pretty rad if you ask me.

What's the expected release date looking like? Any prices yet? seems like the kind of module one might want to have a couple of.

Thanks for listening - I can't wait!

*edit - oh! I hope I'm not the only person to spot what I believe a mislabelled jack! You have 2 jacks labelled CV 1 - I would assume the bottom right input jack is to be labelled Gate 2. Unless i'm misunderstanding...

Looks amazing.

This will also double as a midi cv interface, that is very nice. - I was wondering if it would also work as a microtonal device for midi->midi - inserting this in a midi chain and getting it to "translate" a sequencers midi notes to microtonal notes using "midibend". If yes, would it be able to scale multiple midi devices?

Not only will it double as midi cv interface, you can also use the midi part completely independent of the cv part, there is a powerful midi routing engine implemented.

cv/gate to midi conversion is on our list and currently implemented as a prove of concept. For each channel you can define an output channel which sends note on/off + pitch bend.

midi to µTonal midi conversion is possible, but can only work monophonic due to restrictions of the midi standard.

This has already been noticed and corrected, the picture is a bit older.. Thanks for pointing this out though!

We wanted to build the ultimate µTonal multitool. Having to buy a separate midi to cv interface if you can implement the functionality voids this philosophy.

Release date: As I wrote above, hopefully soon. Price: We need talk to distributors before settling on a price, so no figure at the moment.

Any chance this'll be available as PCBs or a kit and not a complete module? I'd like to build it into something I'm working on.

With the midi to midi part will it be also possible to send tuning tables via sysex messages? This would make multi-timbrality available and bypass the restrictions of using midi pitch bend, the limitation being that only selected synthesizers allow tuning table dumps. The two most common formats for this are the Midi Tuning Standard format and the Yamaha format. The Midi Tuning Standard is currently implemented on current DSI synths (Prophet 6, 08, 12 OB06 etc), the Korg monologue, your own juno 66 and was implemented in 1990s Ensoniq and Emu synths and samplers. The yahama sysex format was used on the DX7IID era of instruments and modules.

Another question.

Is there the ability to add a footswitch to switch tunings? I suppose any trigger input could be used this way with say a doepfer footswitch module.

Is this currently possible or in the works ?

Hi,

current status of this module:
- Software almost finished
- Second hardware prototype with larger display will be assembled next week, front panels powder coated and screen printed. If everything fits and works we will produce the first batch.
µTune will be presented at Superbooth17

I tried to write down all the features currently implemented. This is a very rough list, if anything is unclear please let me know:
----------------------------

µTune is a tool designed to serve all needs that may arise when dealing with microtonal scales in a modular context.
Is is:

- A two-channel microtonal midi interface
- A two channel microtonal quantizer/mapper
- A Scale editor
- More than the sum of these parts

Its inputs and outputs can be freely configured to various functions. It can also detect when an input is plugged in and change its behaviour accordingly.
Here is a very quickly written overview of its current features:

Quantizer / Mapper
- CV inputs adjustable to custom V/Octave
- Inputs can map to scale degrees, transpose or shift a scale
- High precission CV outputs
- Quantizer can run in continous mode, gated or triggered

Midi to CV interface
- Midi from DIN midi or USB midi
- Dual Monophonic and 2 different Duophonic modes possible

Scale editor
- Any number of notes per scale
- For each note edit: cents, fraction or select from a list of common intervals
- scales not based on the octave are possible
- quickly generate EDO scales
- deactivate certain notes in a scale
- save and load scales on SD card in scl format

VCO calibration
- Easily calibrate any VCO using built in tuner
- 10 point calibration of pitch
- save and load calibration data on SD card

CV to midi interface
- microtonal 2-channel cv/gate to midi interface
- uses midi pitch bend commands to generate microtonal pitch

MIDI router
- a powerful midi router and merger
- route notes / clock and sysex independently
- have a usb midi interface independently from quantizer for example

Firmware update from SD card

IO functions
CV out: microtonal pitch, velocity chan1, velocity chan 1/2, after touch chan 1/2
Gate out: Midi gate, midi clock, midi start/stop, pass from input
CV in: map to pitch, transpose chan 1/2, shift scale chan 1/2
Gate in: trigger mapping, gate mapping, measure frequency, trigger random transpose chan 1/2

Planned features
- Automatic VCO calibration
- Live pitch matching using closed loop approach
- Support KBM keyboard mapping files
- Midi to microtonal midi conversion
- Send/ Receive midi tuning dumps
- Switch tunings via trigger in
- .. more

Extensions
µTune features an extension port and we are planning
- Two more channels for a total of 4
- An oscillator extension with perfectly pitched OSCs

Yes, there will be a DIY version (PCB assembled with SMD parts). And of course instructions how to wire it up.

Also planning 5HE versions, but want to finish the 3HE first

Great! More than one can hope for, usually - thanks!

thumbs up

Please send a mail to mail (ät) tubbutec (döt) de

Will put you on the list and let you know as soon as we start taking orders.
Thank you

Hi,

Cool looking module.

Can you please let me know how many hp the unit is so I can make some room in my case.

Also is the module going to come pre-loaded with some scales. How many? Mix of standard plus some more experimental?


Apologies if these have already been answered but I could not see them in the thread.

Cheers,
Andy

Hi Andy, it is 8HP

We are planning to have scales already on the SD card, yes. standard scales of course and then there are some great scale packs out there, but have not asked their creators yet, if we can use them for a product.
If not, it is just a matter of drag and drop for the user to copy them on the SD card.

Various scale packs by Sevish:
http://sevish.com/music-resources/

Xen-Arts pack:
http://xen-arts.net/xen-arts-vsti-microtuning-library/

And of course the huge collection of 4500 scales by Scala creator Huygens-Fokker:
http://www.huygens-fokker.org/docs/scales.zip

If you have any suggestions which scales to include, please let me know.


Jamesf1

Cheers for the information. The Sevish scale packs look like just the sort of thing I am after.

I have also sent an email to your address as I would like to order as soon as available.

Many thanks.

well, but cs30 requires Hz/Volt control and uses s-trig with 5V pullup. Is it ok?

I see, Hz/V is currently not supported, but I will put it on the feature list.

That's very cool, looking forward to the release!

+2 for a DIY version. Non presoldered SMD would be better, I think

I'm glad someone brought up the Hz/v standard. If it could be separate by channel that would allow me to use my MS-20 mini with my euro.

There's a feature request I've always wanted: could the quantized scales be updated realtime by holding chords with a keyboard through the MIDI in? That way, when playing a song live, you could make the whole system change chords of your arpeggiators and whatnot by just following chords in a keyboard!

Awesome module!


z3r01

A couple of dumb questions (do bear with me, apologies in advance), so with this module, I can basically either use a MIDI sequencer, and/or quantise a control voltage source from the modular (without using MIDI)? Also, if I have a MIDI sequence running, I can use the CV Ins to transpose the incoming MIDI sequence etc.?

Bloody hell, have been looking for something like this for awhile now, and not sure how I did not see this sooner.

Anyways, a little feature creep if I may. From what I understand about the module, the CV/Gate outs can be set to different functions (velocity, mod, MIDI Clock/Run), and the module itself has an expansion port.

I was just wondering if it would be possible to have an expander module that would 'breakout' these functions instead? An expander module (about 4hp, or less?) that has additional assignable outputs (maybe 2 per channel), plus a Clock, and a Run/Reset output, would make this whole package pretty awesome.
