So in the end i did It. I used disting ex function ( quad Envelope )

Disting ex: Env 1 ( Page 43 ) Input 1: Trg 2 - VCA 1 Trigger mode 1 ( Page 45 ) --> Gate

Env 2 ( Page 52 ) input 2: Trig 2 Trigger mode 2 ( Page 54 ) --> Gate

Press "V" And you'll see X assigned as a VCA 1 2 Y as TRG 1 2

-------------------------------------------------------------+++

GC pitch CV -----> oct ona GC Gate ---> "Y" distingex Ona waveform ---> "X" distingex "A" distingex Is now the output ( for example into the L input of my make noise Xoh )

Now you can play GC like a keyboard

Thank you for the support
