Looking at the innards of the file, I think that's MIDI 3.14, which
contains commands like MIDIUSBSend.
But I don't have any MIDI hardware, so presumably despite being loaded
on my system it isn't actually doing anything?
MIDI 0.06 seems to be compressed, as it doesn't contain any readable
ASCII strings - but it does contain the header USBMIDI © 2017 Rick
Murray, so is presumably a development of MIDI 3.14?

Yes, the module file is called MIDISynth, but the module in memory
calls itself just MIDI - which is the problem.

It sounds as if I probably need the MIDISynth module in order to
generate audible sound from software that sends MIDI commands, rather
than *either* of the two USB MIDI modules that control external
hardware.... I've tested it on Rhapsody, which has a 'play via MIDI'
option that never did anything previously (presumably because the loaded
MIDI module was busy sending commands out of a USB port), and it does
produce sound output.
