Yep, I tried my old version and sure enough the code is playing as the silent wave!
The version I've presently been working on has already fixed the problem. Unintentional bug fix!
There are two MIDI related bugs still in the original OS, so I'm trying to figure those out as well.
The "live" joystick has been on the wishlist since the beginning. Hopefully can figure that one out. I also found the Arpeggiator key-reset code so I can make that selectable too.
