Seems that when I recall a preset via midi with PC number, the status of the preset it will be permanently ON.
It's important to save the status (on or off) when we save preset, 'couse for instance, i need to use a wha effect only when I engage expression pedal...!!!
It's a common thing I already do with an old M5!!! Cmon!
If is not possible with this unit I sadly return to the store and let go...
