I’m actually in a somewhat similar boat. Currently practicing a live set based around the Digitakt sequencing its own internal tracks and my Model:Cycles and Minilogue XD. Using Logic right now with a Scarlett 4i4 and running the DT with the M:C through its internal inputs as 1-2 and the MXD as 3-4.

For me, the limitation is computer processing power; I use my M1 Mac Mini to compose and produce normally, but I’m using my old MBP i5 16gb for portability. I’ve already conceded to using a stock compressor and a filtered sidechain to duck the Minilogue, but I can’t manage to get a similar situation going for the DT/M:C tracks with the DT’s onboard compressor. I initially tried Overbridge to just process everything individually, but that created notable lag and occasional audio artifacts and I’m nervous that that’ll crash the whole thing in a live setting.

Anyone have advice or experience with a setup like this? OP, I completely empathize
