Glad to hear you are enjoying the new H90!
When designing the UI of the H90, we settled on only allowing P perform parameter for the P switch, A parameter for the A switch, and B parameters for the B switch. We made this decision to simplify/improve the workflow and general UI of the pedal.
We do realize this system could be improved when it comes to the looper and we may consider some changes with how this can work in a future update. For now, my best suggestion would be to use either the 1-button looper, or a 3-button aux switch or MIDI controller if you’ll like finer control of all the looper’s parameters.
