I'm pretty sure it's a software issue cos it only started happening after the os upgrade that improved responsiveness of controls.
I'm no engineer...just an elderly guitar guy , so I might be totally wrong.
Actually it would be interesting if Kemper would give a summary explanation of what is going on when such bugs surface.
Naturally without revealing any proprietary secrets etc..but just a heads up that for example speeding up responsiveness impacted some other routine.
It would actually be useful so that users can decide if an update is essential or not for their particular rig.
For example if responsiveness was not an issue for their rig/use etc they could skip an update and save themselves the hassle of installing fixes and having to contact support.
Just my 2cents... 😀
