I am trying to create a reaction to make an LED on my controller light up when the track has audio playing, and turn off when the audio is not playing. I have tried using
self.song().tracks[0].has_audio_input == True (False for off)
self.song().tracks[0].has_audio_output == True (false for off)
but neither seem to turn the device off when audio stops. I have tried various different listeners to no avail. I can get it to work for specific clip slots, but I want it to apply to all clip slots in a track.
