@EdTheHead I was actually one of those people. My MIDI controller is separate from the PiSound and connected via USB. I use mine to turn on/off effects, similar to your setup:
A few months ago I wanted to expand this pedalboard to automatically turn on/off LEDs if the corresponding effect was on/off. It would have required a major rewrite of the micro controller code and a new program running on the Pi to talk to the controller. When I thought about what I was going to get relative to the amount of work it just didn’t make sense.
