Thank you kindly, @JamO. That promises to be a great feature for what I’m hoping to do.
I’m pretty amazed so far at my new Airstep footswitch which makes this keyswitching possible. I suspect that there are many other programmable controllers with similar features, but this is a new landscape with me and it’s kinda mind blowing. Once I sort out the issue with getting the Airstep to recognize my existing expression pedals at full sweep, I should be off to the races!
