Thanks Jim, that's a really useful reply and gives me some modules to explore. Just to add, I've been developing an ambient style random glitch rig alongside this one but this is very specifically for exploring polyrhythms that still lock to a fixed tempo. So for example there could be at any one time 7 different time signatures running, all modulated for colour and character. I guess in some ways like Steve Reich created a number of years ago.. And not dance music.
I've been on a modular journey for a while now, just tweaking and exploring but it's come to me that I want to create certain music I hear in my head that I can't create on other hardware instruments, which is perfect! New music!!!
I'll check out a few of the things you've mentioned and see how I get along
