Hello,
MIDI PC messages can only be used to change Programs on the H90, you’ll need to use Presets mode on the pedal or H90 Control to load individual presets within the current Program.
You can make inserts active/bypassed using MIDI and other external controllers – https://cdn.eventideaudio.com/manuals/h90/1.7.5/content/appendix/global.html
Let me know if you have any other questions.
