yep i use 2 different synth minibrute and the micro brute for now to use is together

i use that main out minibrute to the right in analog key
the main out microbrute in the audio in minibrute and the fader audio max i use together

but i try somethinks else and it s strange the right in work fine

but the left in works if i press play and launch and sequence with the 4voice
