I assume I need to use CC "Toggle Tuner" in the H9 controller?
Yes, use H9 Control to make the CC assignment. Under the "Pedal" tab, "MIDI Settings", "Assign MIDI CC messages to pedal functions", "Toggle Tuner"…there you can assign any CC number you want. Try using this CC instead of sending a PC change for toggling the tuner and see if it solves the problem.
