In short, Volker Boehm had done some ports of the MI synthesis code in 2020, unbeknownst to me. Once I discovered it a bit over a month ago and compiled his supercollider port, I realized, no excuses, get to it.
The intention is to keep the source as simple to use in an arduino context, so it's NOT as nice from a c++ developers vantage point. But, I think it's becoming approachable for less adept programmers.
Niek from Sluisbrinke has pushed me along, wanting to build a 'Meta-Mi' module: https://github.com/niektb/sluisbrinkie-eurorack-published
I just play these things on my scarp.
