Starting a new topic here, as the old one is very fully and has a lot of very old information.
If you want to test this, it’s with the other test modules here: Releases · squinkylabs/SqHarmony · GitHub
If perhaps you tried this out a year and a half ago, you may have missed the “final” version. It has a lot more features than the first and second test releases. Here’s a diagram from the manual for it: https://github.com/squinkylabs/SqHarmony/blob/main/docs/arpeggiator.svg
