Well, you’ll want to make sure that your H9 is mapping the incoming MIDI CC’s to the correct pedal functions. If you open H9 Control, you can change the MIDI CC mappings under Pedal Settings / MIDI Settings / Assign MIDI CC messages to pedal functions.
Thank you so much for your answer.
Can you please tell me more sepcifically?
I actually tried change it to Midi CC1. but not working.
I went to Pedal Settings / MIDI Settings / Assign MIDI CC messages and changed Performance switch, Bypass, Activate, Toggle between Active and Bypass and Left footswitch to MIDI CC1.Show More...
but none of those works.
Thank you for your help.
