Your midi is setup incorrectly.
To properly use the performance switch via MIDI across all algos, your midi button should be sending 127 when pressed.. And 0 when released. Not 127 when pressed once, and 0 when pressed again.
Youight be able to get partial function just by sending 127 every time.
I detailed it more clearly here:
