You need to tell Qtractor or Muse which sound engine to use to play the
MIDI files. By default Qtractor, Muse or an editor like Seq24 do not
make sound by themselves. When using Qtractor, it can produce sound
through plugins (LV2, VST,DSSI,LADSPA) or through an external app that
is connected via ALSA MIDI (like Qsynth).

Also, David, when using a plugin with Qtractor, be sure to activate the plugin. That was my source of frustration.

Hope that helps!
