Thank you for the reply and inputs SB-SIX.
Yes, probably using samples i can start from Octatrack and later, to improve, i could add other gear like A4, AR, Virus TI or something else.
It’s also right your live point of view, the less, the more.

About the knobs i’m thinking also about Encoders vs Pots, you know, with mutitimbrality one thing is to use Knobs that don’t remember position for each part, another thing is an encoder always ready, so a choice could be betweeen A4 and NL3.
I hate my AN200 shared knobs for filter and amp envelopes, i have always to use shift and rememember original position to don’t get drastic sound changes, also when switching between patches.
