Hi everyone,
Just seeing if this issue was solved for OP Maginethat or Heiree ?
I am having this same problem, I don't have access to the MIDI logs as we have a playback tech who looks after these messages, I will confer with him tomorrow.
Happens 50% of the time for us, when changing performances the LCD screen indicates the performance has changed and we're on the correct slot but the sound has not changed. I correct it by cycling to the next slot and cycling back.
I am happy though to see this problem is MIDI related and not Kemper related.
From my understanding we are only sending PC messages, we do not use MIDI for anything else besides rig changes, however we have a few Kempers being changed and we run MIDI long distances using line drivers, but I would think if the message was getting lost or interrupted the LCD display would also not change.
Appreciate the help or atleast confirmation a fix has been found.
