While I realize score playback is not the main function of MuseScore as it is today, I have found a great secondary use for MuseScore now that Chord Playback is enabled in 3.5:
Using Playback as a backing track for horns or other single note instruments.
I mute the Normal channels in the Mixer, but un-mute the Chord Symbols; enable the Count-In option on the Play Panel and I can practice away, a wonderful thing with the social distancing and lack of opportunities for jamming with other musicians right now.
The only thing I wish was an option was a light, a blinking icon or something in lieu or in addition to the Metronome click if I wanted to have the Metronome enabled as well for practice, but not as a click. I also think a flash should be an option for Count-In as well.
The "light" or flash could be located on/in the Play Panel, which makes the most sense, I guess.
If there is a way to do this already, please enlighten me. If it has been addressed in a previous post, I missed it and apologize for asking again.
If it is coming, thanks!
