Hello sigitar,
I recommend using the “P Act/Byp (M)” command for this type of control.
An Active/Bypass parameter such as “P Act/Byp” will toggle between the active and bypassed state of the Program, so long as it receives a MIDI CC value of 64 or greater. This means every time we send a controller change message from a MIDI device with a value of 127, this command will change the current active state to the opposite state. Sending a value of zero will have no effect.
When using the momentary version “P Act/Byp (M)”, the bypassed state will be triggered with a CC value less than 64, the active state will be triggered with a CC value of 64 or greater. This option is best for when we don’t just want toggle between state but we require specific control of OFF and ON commands, as in one button for off, another button for on.
