All of the Program, Parameter, and Settings changes done in H90 Control will be reflected on the pedal UI and vice versa.
In your example (using Performance Parameters) there is no UI in H90 Control that would display if a momentary footswitch is engaged.
I’m assuming you are referring to the Shift Performance Parameter of Prism Shift? When this is engaged, the parameter knob itself does not change on the pedal UI or in H90 Control, but the Shift is changed under the hood.
The interval shifts are explained here: https://cdn.eventideaudio.com/manuals/h90/1.1.2/content/algorithms/pitch.html#prism-shift
Let me know if that clears things up for you.
