Has the cause of this ever been addressed? Anyone got any insights on the issue?
I've just got a helix floor and the same thing just happened to me. It got stuck on my second preset. All other switches and rotaries work fine except for bank up/down switches and the preset rotary switch.
I plugged it to the laptop and it let me change preset. This seems to have got it out of the jam but I can't be doing this live.
Cheers
Elbee
