Just wondering if the H90 has extra hidden expression pedal or external switches that an OX pedal can be developed for it like for the H9. I have a 3 switch pedal and an expression pedal working with the H90. Now that I am becoming more familiar with the H90 I could certainly use a few more external switches for live work!
But looking at a silver lining, maybe now is the time to learn how to use MIDI to do what a few more external switches could do!
