I don't see anything in the code that obviously limits what you set step repeat to. I'd say send me either a copy of the project or a short video via
jim@five12.com. For video, you can send email or iMessage. To send me the project, connect the Vector in disk mode, find the folder for that project, .zip up the whole folder and email that.
Two things I'd want to look at: is it a UI update issue, or is parameter modulation somehow involved...
Cheers,
Jim
