I have studio one 6 professional.
My midi controller is an arturia essential lab mk3. It's setup as a keyboard and a Mackie control (nightmare to get working I'll try and share a video of my setup when I get everything working). Some of the controls work: play, stop, record, rewind etc.
Some of the things aren't automatically mapped which is expected. One of the first I decided to try and map myself was the metronome. I went into midi learn. I see the cc command come in. I switch it to be an on/off button. I right click and select assign. Then in the options of what to assign I only see open metronome setup. If I assign that it does indeed open the setup when I press the metronome button. But what I'm after is the equivalent of assigning it to do the same as pressing the letter c on my regular qwerty keyboard to toggle the metronome on and off. How do I achieve this mapping?
