I do it on a H7600 and it is the same Hex codes as the Orville. My MIDI controller is a Behringer FCB1010 which does not send long Hex messages, but there's a free software called MidiTranslator that can read a simple program change number and add any Hex to it. Works like a charm. I can control *anything* on the H7600 with my feet, but I need a PC in the MIDI loop.
