Speaking only for my use case:
Having global control of reverb parameters, etc. would be useful, but would not need to be controlled by an expression pedal.
What I would like to see is a way to control the delay level, using the Kemper remote, with an expression pedal, in each slot of a performance, without having to use the existing morphing. As it stands now, I have to use morphing to control the delay level and; therefore, am not able to use morphing for anything else. And the delay level control needs to be tweakable for each rig or slot in each performance...and for each delay in a rig or performance (like it is now using morphing). Having expression pedal control of the delay level only would be great, and if the control could be extended to other delay parameters (the way it is currently is using morphing), that would be even better.
Thank you for considering this.
