Just to elaborate….
Here I'm having erratic issues saving feedback levels on some patches.
Also, learning harmonies seems inconsistent – and often don't seem to save to the patch.
Harmonizers don't seem to keep interval settings.
controller pedal needs to be pushed all the way down and then back up to capture mix levels (if they're mapped as part of the controller setting on the patch)
Good luck tracking these issues down, and I hope you can recreate what some people are encountering.
