Hi @jofemodo ,
I’m confused now. Seems like there is some misunderstanding. I’ve never talked about ..
You can use active mode just for the keyboard that play the piano chains (3 & 4), while keep using multitimbral for the externally sequenced chains (1 & 2).
This was another topic ( Change USB Midi channel in multitimbral mode ). Let’s stop here with this topic, I’ll find a solution for my setup with the built-in possibilities of Zynthian. I’ve explained my use case IMO, perhaps understanding the “functional point of view” in a different manner.
Regards
