Hooked up a Boss FS-6 footswitch & programmed to switch up & down between profiles. I have a good clean & then a Diezel VH-4. I play metal so need pretty well timed switches.
I have a significant (maybe 0.25-0.5 sec) delay when I switch - so much that I have to start anticipating switches (hitting footswitch ahead of actual timing) which I think we'd all agree isn't great. Quick look on the net shows some mention of this, but posts are pretty old.
Has this been fixed? Could be a problem for me if not.
Does the Boss switch change state on press or release? I have one I bought for my HX Stomp but honestly I've never used it.
Also, there's a couple settings somewhere in the system menu to deal with lag between patches. One talks about cross-patch blending or something like that, and the other one is constant latency, which I understand to mean there is a default "time gap" between patches, or if the change can be made faster, it will. Now, since I don't have my Kemper in front of me, I can't point you any closer, but it may at least be something to look into. Good luck!
