“I recommend watching this video to learn how to assign expression pedal (HotKnob) ranges:https://youtu.be/_gDiAys5L-4″

I already know about this and do it all the time on my main rig which also has a H9, but with an expression pedal.  I don’t know if it’s a factor but the Rotary patch that’s giving me trouble with the FS3X on my fly rig is the same patch i use on my larger rig with the expression pedal.
