Switching from preset chords to single notes on the fly

What's the best way to do this?

Pedro Eustache does this in a daw with the sylphyo, but it's only for mac OS - I don't remember the name, but he binds it to elevation or the slider.

What I tried was using the insert piz here midichords plugin with a midi pedal, bind it to a CC when pressed, then bind that CC to Reaper actions to go from one track to another, but the pedal I got from temu is not great. Three out of 4 buttons encounter some slight resistance when going down, and buttons 2 3 and 4 have increasing latency compared to the first, so I'm considering sending it back. Maybe someone could recommend me a better product?

Insert piz here uses midi program change to swap presets, but midi program change causes an audible drop, and it's not convenient to use on the sylphyo.

Maybe there's a more convenient way to do this by binding elevation or the slider to chord presets?
