I would love to see this feature added, and from the little I know about programming, I don't think it would be hard to implement at all!
I know that you can use the effects switches to toggle two different effects, but it would be great to be able to perhaps hold the switch down for 1 second to turn both off.
This would give my Kemper much more flexibility with the effects. For example, if I have delay preset A loaded in slot X and preset B loaded in DLY, then I could assign them to a toggle on the Remote - With the ability to also turn them both off when I don't want delay.
Another example would be for when I want to store a rig with a chorus and a phaser, but I never want to use them together. I could use just 1 effects switch to toggle them both off, or choose between them.
Thanks for hearing my suggestion! I would love to see this implemented.
