I recall reading articles scattered across the forums that would relate to this but would be nice to have a compilation of tips in one go-to place-
In the event there is a problem with your Kemper at a gig and you aren't able to reach support or these forums, what are the things to do or try?
ie, i had a situation once where there was a power-cut and i had to reload a whole back-up to resolve it (which took ages and didnt actually solve it) but, afterwards, tec-support said if you hold down RIG whilst powering up it will clear the buffer and may have saved the day (wish i had know that at the time!) Having a backup on USB stick should be part of your first-aid kit so seeking more tips (lke the hold rig button and restart) to aid possible scenarios or situations that may help save you at a gig.
fire away....
