Thank you jameslo !
I could solve the problem using clones of an abstraction with argument.

Hello,
I made a polyphonic synthesizer with 8 notes with a repetitive pattern for each note.
I would like to do the same with more notes, but it would be tedious.
Do someone know if there is another way to do it without repeating the same pattern for each note ?
Thank you !
