This is brilliant, and just what I want from a Euclidian sequencer!
Intuitive and easy, lots of options without being overwhelming, really fun to play with, and a simple way to get Euclidian midi patterns into my host for further editing as well.
The only additions I'd want would be the option to toggle individual beats on and off in the sequencers (maybe not in the Euclidian spirit!), and per sequencer probability in addition to global probably. Other than those, genuinely couldn't be happier.
