Excellent information, thanks!
A few more questions:
Do you experience the issue in Performance Mode or Browse Mode or both?
I only use browse mode intermittently to show someone a quirky profile I might have. At rehearsal it's 100% performance mode.
Are you using a Profiler Remote and /or any other remote control equipment?
Using the kemper remote with a moog EP-3 expression pedal plugged into it.
You are referring to a reset ... have you tried a simple restart?
This is probably what I meant. Simply turning the dial to off and after shut down, turning it back to performance.
Are you using the Effects Loop function and is it somehow involved?
No effects loop or any other 3rd party hardware.
What happens, if you switch into Tuner Mode and unselect "Mute"?
Will be experimenting today. I'll be back to answer this later.
Or have you tried an Init Globals in the System Settings?
I have not, but was tempted to do that today. I'm torn between trying to recreate the problem here first with the Kemper in its current state in order to really pinpoint the issue, but at the same time my Kemper is second hand and who knows what the other guy may have done to it. I will probably just do the initialize and start from square one as I feel any data gathered will be more valid that way, should the issue arise again.
If you load an Output Preset afterwards you might be back to normal within seconds. But it would help us to know, where to search.
Thanks so much for the reply.
