You can control the H9's input volume or output volume with MIDI, and we had a problem in an earlier release where some MIDI foot controllers were sending bank select messages that were being misidentified as MIDI CC messages and turning the volume all the way off. To check if this might be happening connect your H9 to H9 Control, click on the Pedal button in the bottom menubar, go to MIDI Settings, Assign MIDI CC messages to pedal functions, and scroll down the Input Volume and Output Volume pedal functions. If they are assigned to any MIDI CC messages, please unassign them.
