I have a problem and I do not find a solution on Internet !!!
I connected my Minimoog Oldschool with a Doepfer MCV4 towards Atari ST Computer (or Apple towards M-Audio Midi…).
I wish that my Midi connection play the notes on Minimmog without I not posing the fingers on the keyboard.
The liasion Midi is carried out (red diode ok).
But I am obliged to leave a finger on the keyboard to hear the played sequence.
It can be transposed if I change note. But it is not what I wish. I want just to intervene on Minimoog to change the parameter of the sound (LFO, Filters…). I want just that my keyboard behaves like a expander.
If you are using midi, then you need to send a midi signal to close the envelopes, essentially, you are simulating the action of pressing the key, you have to thus simulate the action of releasing it. Try to connect it to the blue envelope gate jack on the back of your Voyager and see if that works.
2 cables from your midi/cv convertor. One is PITCH CV and the other is GATE CV. The PITCH CV controls the freq of the osc. The GATE CV controls the VCA. You plug it into the ENV GATE IN jack on the VOS and set the switch to External/ON.
