I was trying to set up BTT to use Media keys (Volume up/down) to control Music.app volume (I'm usually using Airplay) when it is playing music, but control system volume when it is not.
This is the way I've set it up:
Following Play/pause for apple music & podcasts app. BTTCurrentlyPlaying & BTTCurrentlyPlayingApp not available? - #2 by Andreas_Hegenberg I've set up listening to BTTCurrentlyPlaying* variables, and it does work - it only sends the keystrokes to the Music.app when it is playing, and it does the job.
Unfortunately the "Else" part doesn't do anything - if the Music.app isn't playing anything nothing is happening. What am I missing?
