How to cv control minitaur?

Meriphew · 2018-02-18T15:57:27.843Z

A4 CV A/B out to Minitaur’s pitch and gate inputs. I can get it to trigger a sound, but octaves don’t change, and the note is the same no matter what key I press.

Oh that’s beyond what I’m doing. I just wanted the damn thing to start and stop and make a sound.

have you tried using the lower notes? The minitaur doesn’t track over the entire keyboard so you end up getting the same sound past a certain octave/note that I can’t recall off the top of my head.

Never had any problems controlling the minitaur from the A4/modular for the past many years

Minitaur for live DAW-less setup Other Gear

the midi from the A4 will only be able to clock the LFOs, you can achieve control from the A4 to the minitaur note on off (gate) / pitch / filter / volume cv from the 4 CV outs of the A4. Setup the CV track for the ABCD outputs to be A -> cv gate -> minitaur gate cv input B -> pitch cv v/oct ->minitaur pitch cv in c -> value lin -> minitaur filter cv in d -> value lin -> minitaur volume cv in of course filter cv and volume cv aren’t essential but if you aren’t using those 2 cv outs might a…

I’ve tried switching the A4 into lower octaves but still nothing.

you’re certain that you have pitch cv assigned to the correct side of the cable? You’re using a TRS to dual mono cable as well?

Meriphew · 2018-02-18T16:57:17.492Z

Yeah, cabling is correct (TRS insert to two TS male outputs), and they’re plugged in to the proper jacks.

On the Minitaur Editor I have the CV mapping set to default. Do I need to change anything in there?

Thx for your help BTW.

One thing I noticed is that the Minitaur still makes the single note sound regardless of whether or not I have the (tip) cable plugged into it. Maybe I have a bad cable (just bought it).

Just tried another cable and got the same result, so it isn’t the cable.

hmm everything should work with default settings on the minitaur. Can you try saving your current A4 project and doing an empty reset of your machine and re-setup the cv tracks? Also try doing a factory reset of your minitaur, if it wasn’t brand new who knows what has been tweaked and saved through the editor.

Also do you have any other gear you can try sending a CV signal to? If you are getting proper v/oct output from your cv tracks to another device then you know for sure something’s up with the minitaur.

also do the same sending midi notes to the minitaur to confirm the oscillators are working OK.

You should be able to isolate where the problem lies after this

Meriphew · 2018-02-18T21:48:18.035Z

It’s a brand new Minitaur, but I have used the Moog Editor to reset everything to default, and to calibrate CV. I will try sending midi to it though, that’s a good idea. Thx.

Tested the Minitaur with midi and it works fine.

Open_Mike · 2018-02-18T22:06:57.205Z

I don’t know if it will solve your issue but never the less moogs will sort of “set” the oscillators to the last voltage played on the keys (if there) or by midi, and then the cv input will offset the oscillators from there…

To get my Little Phatty to work in proper tune with pitch CV from Threremini I have to have pressed a low C last, I forget which Octave…
Here it’s mentioned earlier in the thread:

romanicks:

The only thing which is quite annoying is that I always have to send a C0 to the Minitaur via MIDI before starting to send CV. If I don’t do that, the Minitaur may play wrong pitch (i.e. if I play a C1 on the A4, the Minitaur will for example play a G1).

Once you get things sorted this can be used for transpose…

Meriphew · 2018-02-18T22:30:08.083Z

I’ve spent about 8 hours trying to get this sorted with no luck. I just followed your steps exactly and now it’s working. Thx a lot!

dobermate · 2018-02-18T22:48:48.315Z

Oh man, 8 hours…but extremely happy to hear you soldiered through, congrats! A4 and Minitaur is a wicked combo.

Jameshenry · 2018-02-18T23:42:19.326Z

Shit is brutal eh?

I haven’t managed to C/V-control the MT through my AK yet, but one day I will. And then I’ll make a comprehensive step-by-step video (why on earth isn’t there any yet?), so nobody will ever have to struggle like us! Promise!

Jameshenry · 2018-02-21T13:13:50.840Z

I’m gonna come back in a year and check.

jaschar · 2018-02-23T11:01:01.027Z

Still not there, but I compiled all seemingly useful input in this doc:

docs.google.com

MT & AK

After you do the updates, connect your A4/Minitaur and also connect to your computer with the editor. From there do a note calibration on the Minitaur. Set your settings in the A4 @ 1V for C2, and 4V for C4. Next follow these steps.��Set c2 to 1 volt...

Anybody achieving C/V control based on this input is bound to make a step-by-step video

Meriphew · 2018-02-24T20:51:51.890Z

Did you leave C2 @ 1v and C5 @ 4v once it was set up? Everything’s working great for me with those settings, other than the Minitaur being slightly off pitch.

Meriphew · 2018-02-25T02:16:56.625Z

In the process of trying to sort out the out the pitch issue, I hooked up a synth via midi to the Minitaur, and got the Minitaur working immediately. Unfortunately when I went back to CV’ing the Minitaur to the A4, I was completely back to getting only single notes(no matter what key I press on the A4). I’ve tried doing the (Dobermate) steps again, but I’m not getting anywhere. Sigh

dobermate · 2018-02-25T20:02:12.004Z

You know what - I just checked and I knew I had messed with the tuning but apparently this, or something done in the same tweak session, resulted in changed values for pitch 2.

Values really don’t make sense, but I remember I did the tuning part tied to tuner and had a sequence of e-e programmed to hear it working ok.

Sorry that I cannot be more specific :(.

EDIT: pics don’t work it seems, will try upload later.

Meriphew · 2018-02-25T22:17:27.472Z

I finally got it completely set up including being tuned to the A4. I had used a tuner on it the first time I tried doing this last week, but no matter how I tweaked the voltage, the key was always off. I did go into (function + note) the Note section for the CV track and set that to major. I think it might have been set to minor. Here’s a few pics of the final set up process (please excuse the mess).
