Mother 32 and Minitaur Pitch problem

Hi,
I've purchased a mother 32 lately and try to patch it to my minitaur, so far what i did is quite obvious :
KB out > Pitch in (minitaur)
Gate out > gate in (minitaur)
Audio out > audio in (minitaur)

My problem is that the Minitaur pitch is too far low, like 2 or 3 octaves below compared with the expected notes from the midi keyboard
Does anyone encountered this problem ?
I've been looking at the minitaur editor standalone but didn't find a parameter to retune the minitaur (pitch cv calibration option +1 or +4 get it very wierd)

Where do you think is the problem ?

thanks !

Nobody ??
What's wrong with my question ?
I'm a bit confused nobody encountered this pitch problem with minitaur and mother 32 association

I'll try to do my best to test them tomorrow at our workshop, but I can't promise you anything.

If I can't, I will during the week. Please do a bump here if I don't

Ok thanks
So to be more precise : when I press a C1 on my midi keyboard it played a C1 on the mother 32, but something like a C-2 on the minitaur, so to have the range of notes enabled by the minitaur I have to play up to C2, accordingly the mother 32 played on very high pitch :(

I guess it comes from the difference of voltage range between -5+5v for mother 32 and 0+5v for minitaur : is there a way to fix this so as to have the minitaur play the same note as the m32 ?

I couldn't make it work, either. Nor with the Model D.

However, it was way better (not perfect) when the Mother-32 was set as slave (using the 1V/Oct) using the Model D's CV outs

I understand there is something related to the scale. Will keep researching during the next weeks.

You should take into account that not everybody has a Mother-32 and a Minitaur

We do, since we are distributors for Colombia and we have these at our showroom

Hi,
so there is one good news : my minitaur hasn't any specific problem, as you've encountered the same issue, it appears to be a general compatibility problem between m32 and minitaur
I'm aware that having both minitaur and m32 might be rare, though it appeared obvious to me to patch those two device

I hope there will be a solution

thanks again, keep in touch

In the mean, time, you can use MIDI to hook them up and that should work.

Hi,
yes it works fine this way of course with a multiple midi I/o device, but I want to use the midi in of the m32 to receive midi clock from my other synth which is a Dave Smith Evolver :) And I want to avoid using any DAW in this set up
cheers

In that case you might need an attenuator or voltage source to match voltages.

Like the atenuator of the CP251 ?

ok I have a CP 251, I’ll plug the m32 main out to the attenuator of CP 251 and send it to Minitaur Pitch in, and will report soon if it works

In the mean time it would be great to have some kind of tutorial about how to use the calibration on the stand alone usb interface of the Minitaur !

cheers

Ok, so it works with the mother plugged to the attenuator of the CP251 and sent to the minitaur but still not at the same octave, anyway I do it differently by sending sending midi notes from my midi keyboard to a Motu Express and send both to minitaur and Mother, and then launch a midi clip from Ableton Live. So I gave up connecting the mother directly to the minitaur as I would trigger the mother's sequencer and wish the minitaur to play along with it ;
this set up works fine too sending the Mother LFO to the LFO rate of a moogerfooger live the MF102 :)

cheers

Using an attenuator on the cp 251 wont work well as the control voltage will have an exponentiall attenuation. Try instead to use the offset function. With that you can offset the kb output with one or two (or more if needed)volts/octaves.
