Quick headsup: I'm also just on a smallscale rack with a bit of sequencing and modulation.

Looking at this build, even with the addition changes and everything I don't think this is a fun sound machine to have on the couch as you have a lot of menu diving, and program heavy, modules. While you still want to connect it to another device for also programming sequences for example.

Pams New Workout, Beehive, FX Aid XL, o_C, and the disting will all need time to setup for most new patches. And probably lots of "debugging" when stuff is not working out as expected.

I just checked and saw that (without midi in) my build currently weights in at 58 hp, so it might be interesting to see another approach of a tiny rack. And what I can do right now.

Also my biggest takeaway from my small setup: Get VCAs, linear ones for CV, exponential ones for audio. The Cold Mac looks fantastic, but might be also a good source for headaces ;D
