Switching Tuner On/Off with a MIDI controller using the CC#45 works fine as a toggle.
However I’d prefer to have one distinct command for activating and one for deactivating.
Only this way you’d be able to switch back to a certain scene or preset while automatically deactivating the tuner at the same time, no matter what status it was in before.
Much more versatile and less error-prone in live situations.
Toggle functionality can still be maintained with existing CC#45 if preferred by other users.
