I have the nano control 2, and i use it with ableton live 9 on mac.
I use the mute buttons to mute/unmute tracks in ableton, but the LED is not acting as it should.
It doesn’t match the ableton track, basically the mute lights on the control just seem to stay on.
I have opened the korg control editor, selected my device, but i can’t seem to see what to do from here. I have gone to ‘common’ and selected LED - external’ then clicked ‘communication - write scene data’ but its still the same in ableton.
Have you made any changes to in the editor software before this issue appeared? I’d try to reset the unit to the factory settings or have load the correct settings file eventually. (don’t take this for 100%, I don’t have any experience with that controller)
