The heart of the system is the bitbox.. Which has reverb and delay, adsr, vcas, mixer, a ton of sounds (v. Per octave) plus drum sounds build in, the bitbox was my first module from which I build around.. The stereo mixer in the case was used mostly for submixes for the effects..
I often patch things up, sample those and do percussion.. I also own a punch of soma labaratory gear which is fed into the 4ms input (generates trigger, envelopes..) and then I experiment a lot..
I live in a place where nobody is interested in synths.. So I really enjoi this conversation 😉
