I installed 2.1.2-3+b1 from the Stretch repo and it just froze at it's splash screen. Built 3.0.2 from their website and it seems to work fine so far. It would be nice to have it available from MX repo.MusE is a MIDI/Audio sequencer with recording and editing capabilities written originally by Werner Schweer now developed and maintained by the MusE development team.
