I use an eventide H9 in the effects loop in the X slot. On all my Rigs in performance mode, I keep the X slot for use with the effects loop. but in most slots I keep it saved as bypassed. Thus, I'm not using the loop in most of my slots, but always can go to it if I like, since the loop is simply bypassed. While the kemper handles the spillover fine when bypassing the loop, or even changing rigs with to another rig with the loop default on, not so when I switch to a rig that has it bypassed. For example, if in slot one I have the loop on in the X slot using an H9 delay, and I switch to slot two with the loop bypassed, (though still assigned to the x slot) the delay doesn't spill over. This is an inconvenience, since I'd like to avoid doing a double step each time.
This seems like something that could be an easy fix since the KPA can already do effects loop spillover from one slot to another.
Yes, I know that I could simply send midi messages to the H9 including off and then simply leave the loop on both slots and I in fact do that sometimes. However, I have a couple performances in which I leave midi settings blank, so that I can use various delay and reverbs presets on my H9 on the fly, in which case pre-programed midi messages won't work. So I send no messages on these performances and change presets on my H9 manually. This feature request would also be useful for those using non-midi capable delay effects in the loop.
