I programmed two of my MIDI board's buttons to query the status of stomp C and X respectively via SysEx, and then send a SysEx message that switches them the other way around -
EDIT: does not send a SysEx message to change the stomp status. Only to check the status. The change is done via CC.
I've since updated (i think i last tested it on 2.1) and today, prepping for a gig, the buttons went haywire - made performance mode jump to performance mode 56 and turn stack off etc. - completely bonkers.
Is there an explanation to this? Did i miss some MIDI documentation change or is this a bug?
(I know switching effects on/off can be done more simply).
