I'm trying to create a backing track using a MIDI file I created (from sheet music written in MuseScore3) and the Maestro Concert Grand v2 gig file from /instruments. How do I tell LinuxSampler to play Maestro using my .mid file?

You probably want to use graphical frontend application like QSampler or Fantasia to load your sound into LinuxSampler.
