Hello,

You can assign your MIDI controller to the active/bypass states of Presets A/B by making a global mapping. For example, you can make it so CC1 will always toggle the active/bypass of Preset A, and CC2 always toggles the active/bypass of Preset B.

Information about global MIDI mapping on the pedal or H90 Control can be found in the manual below:

If you update your pedal to the latest software, you should see a popup for the active/bypass state when you are in Select Mode.

Let me know if that helps.
