Thanks @farkas !
I basically watched most of his videos before coming up with the first version. While I agree that I needed a bit more modulation and utility, it’s interesting that he also does most modulation by hand and does not have too much utility. Of course he has quantizers, precision adders and so on and over all uses a more elaborate sequencer setup than I would do. But the Black Sequencer does a lot of this in-house. He also does not have a lot of attenuverters or similar.
Interestingly enough, he mentions the system Surgeon uses, which is even simpler. Both Surgeon and Blawan do not have a lot of modulation or too many utilities besides their sequencer lines and both very small live racks.
Or did I miss something? I find this discussion super helpful because it makes me rethink my approach. Also thought of switching to 12u/94hp but actually want to have a rather small system with the approach of less is more. I know that this is more difficult but otherwise it would be boring.
