Musescore doesn't see my soundcard nor my midi interfaces. So, no sound.
Musescore does not see my Soundcard (RME BabyFace Pro), nor my several MIDI keyboards, and also MIXER and SYNTHESIZER and PLAY button are greyed.
Maybe it has something to do with Catalina. Don't know....
I've tried everything I've read at the posts (factory reset / install-reinstall app / check security-privacy at macOS Systems Preferences..etc). Nothing has worked. It happens with Musescore 2.3.2 AND with Musescore 3.5 (I have both installed here). The last time I've used Musescore it was OK, and it was before I have upgraded to Catalina. That's why I think that maybe there is some compatibility issue about the OS.
Thaks for any help.
