Just adding my request for this as a feature too: remembering slot effect switch settings when switching between slots in a Performance.
Not bothered about it remembering settings after switching from one Performance to the next; just for the slots when staying within a single Performance, exactly as when RM is connected.
I had been using separate outboard effects recently with my Power Rack (so the remembering of stomp box settings wasn’t an issue) but wanted to thin-down the setup to just take the Kemper & Remote to rehearsals - seems a bit odd that this function is there with RM connected but not when the Kemper is used live, on its own.
