I don't believe so. The file I'm opening has a .MGU extension and is 55k, which to would seem small if it contained any audio. There are no .mp3 files in the folder.

I've just tried changing the instrument to another MIDI (25 acoustic guitar), verified the mute, it now plays the guitar but again it doesn't mute. I then tried "no patch", but...

...that's another oddity that I've never properly understood: from the mixer I right-click, "Select MIDI Instrument patch"->"Select no MIDI patch", but it still plays the instrument, where I'd expected it to not do so. I do note that in the mixer description field it says: "No Patch" and "instrument: 0 <no patch change>", where that word "change" would appear significant.
