If the Monitor Output Volume on page Output Volumes in Output Settings is moving by itself, this could have various reasons:
1. the pot of soft button 2 is defective. This should then also show on other screens e.g. the "MIddle" on the play page should also move by itself.
2. an expression pedal is conencted and configured as Monitor Volume Pedal and there is a cable plugged in but no pedal at the other end or these are defective
3. MIDI CC# 73 is received, which controls Monitor Output Volume
Thanks for the suggestion - have checked all of these and it's none of them unfortunately
Fairly sure this is a hardware issue but ive not heard back from Kemper in 3 days - starting to panic as I have gigs coming up and need this fixing quickly.
