i’d like to use an external pedal to recall and control the wha. I have a mission engineering pedal with the switch and i’d like to use it to recall the program (with the switch) and immediately control the wha. In this way i can recall this program from any program.
Only MIDI controllers can recall a Program. Auxiliary switches like the one on the Mission Engineering expression pedal can be programmed to control active/bypass states but not to recall a specific program.
It’s important to note that if you want to use the switch on the SP-H9 and the expression pedal, you need to connect to the H90 with a TRS to Dual TS cable because the inputs can only be configured for an aux switch or expression, but not both.

Also, i’d like to use the expression pedal like pedal volume in the other program (e.g. controlling the out gain of the program) It is possible?
Yes, the expression pedal can be mapped to control output gain on a Program basis. Here’s how to assign any parameter to aux or expression pedals: https://youtu.be/5y14LwN9oAk?t=2888
