Yes, it would work with any synth with CV/gate input


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!

We will be at Superbooth 2017 presenting the µTune.
Come visit us at booth 305 and test it smile

d'oh! 1000 I cannot believe I missed you guys at SuperBooth. Last night in Berlin and after everything I see this; sad banana Must-buy for me. Please make this happen!

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.


+1 !!


+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!

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.

Noted. Some SMD parts have a really fine pitch (0.5mm), nothing one would want to solder by hand. (we did it for the prototypes, but it is no fun)

Of course. All features can be set for each channel independently.

Not excactly sure what you mean. Could you elaborate?

The functions of the expander module's inputs and outputs can of course also freely set to any function. So it is not a problem to always have clock, start/stop, etc.

Thanks for the reply, tubbutec.

Ah ok ok, I misinterpreted the part about the expansion module. Somehow I misread it as separate expansion modules for different functions. My bad. d'oh!

With regards to the expander, any idea how many hp it is going to be for now?

Pretty much sold on the module, and eagerly looking forward to it. thumbs up

Thanks again!

This is a badass utility. Is it capable of polyphonic aftertouch? I'm imagining several uTune's chained together via midi. Also, a feature I'm sure a lot of people would be interested in is an auto tune function. Would these be possible in future updates with this hardware?

Currently trying to fit two more complete channels (8 sockets) into 2HP, but can not promise anything

This will be possible but maybe not necessary. There will be an extension module with two more channels and you can chain several of these for even more channels.

Currently there is a manual VCO calibration procedure which you perform once for each VCO. We will automate this, so a VCO is characterised and calibrated with the touch of a button.
You can save and load this calibration on the SD card.

But maybe what you are thinking about is a continuous measurement and adjustment of the VCO frequency. This feature is possible with the current hardware, but we have not tested it yet. It is also somewhat debatable if this is a 'good' feature at all: By creating such a feedback loop, the original characteristic of the VCO (the reason why you would use an analogue oscillator in the first place) is replaced by the characteristic of the feedback loop.

Any chance the expander's inputs can be set up so that the NoteOn information also has CV-controllable velocity? It's something I appreciate on the a-192-2 and ADDAC222 and I'd love to have it here as well. Seems like this isn't an option with the current hardware options unless you map CV input #2 to velocity which is a loss in my humble opinion.

I wouldn't mind doing that via the expander if possible. Especially if you keep it at 2HP.

I guess there is no banana version in the cards, is there?
justintonation
Sorry if this has already been asked. But how will it treat slew, slides, portamento etc?

Enjoy the show!

Put velocity for cv-gate to midi converter on the feature list. Thanks for the suggestion.

Currently not, no. We will however offer a DIY version with unsoldered jack sockets. This should allow it to easily use banana sockets instead.
An important remark about this however: With banana jacks there is no dedicated ground connection in connector and wires. Instead a common ground on the backplane is used. This may lead to additional noise on the CV output which might lower the precision. We have not tested this.

justintonation wrote:

Currently this is not implemented. It is of course possible to implement these in software. However it is debatable if adjusting portamento parameters with the on screen menu is desirable. I will put it on the feature list if you like, but maybe also consider using a slew rate limiter for this task.

We are now working on several fronts:
- Finding the right manufactures for front panel and SMD assembly, getting quotes, sourcing parts, etc.. (almost done)
- Building a few more units by hand for beta testers (sorry we already have enough)
- Finishing the bootloader (firmware update from SD card), so beta testers can actually receive their units
- Software is currently working and the module usable, but with you guys adding feature request all the time of course software development will take some time..
- Designing the extension module(s).

Sorry i think i did not explain my question correctly. I am wondering what happens to pitch cv from analog sequencers such as Doepfer a-155 and Verbos multistage which add slew to their outputs. I have never used any quantizer before. Does the quantizer preserve portamento or does it quantize rising or falling cv to the nearest step in the scale?

Thanks

Yeah, this doesn't seem useful to me. A more standard tuner (A=440, 443, 415, whatever) would be very handy though. Sorry if that has already been listed as a feature already.
It sounds like this is the way you'd be going anyway, but for the record I'd want a full kit with all the parts and the smd stuff pre-soldered.
As far as glide/lag goes, I say don't bother. Unless you're going to add a dedicated glide knob, menu diving to change a lag value doesn't sound fun. Ladik makes a couple affordable 4hp lag modules- I'll get one of those.
Also- was changing tuning with a trigger a planned feature or just a possible feature? I get confused. This seems like a must to me.
Thanks for all your hard work. It's nice to see the pics of the real unit!
Phil999
why would you want to change tuning with a trigger?
zed888
Because you could use a footswitch if you have your hands full, use a more convenient button/controller, switch tuning in the middle of a sequence, etc...
