ON a Mac
Can you just go from GO > Library > H9 Control > Preset Lists ??
within that folder are the preset lists. you can compare them to each and drag / drop / delete as necessary. seems pretty easy.
HOWEVER, I don’t have my pedal hooked up right now, so not sure if this will work. can I open h9 control without the pedal and check?
seems like the easiest way to organize if you have a lot of presets and lists
