I am playing Iter Vehemens ad Necem, in short IVAN, on Winlator.

Is a ~25 years old rogue-like game that uses MIDI as background music. Sound efffects are instead wave files. MIDI files are just a series of notes a sound card plays back with its internal musical instruments, much like a digital music sheet. Modern audio cards no longer have true support for this now ancient audio format (still used to this day actually, but only on specific music production devices), and desktop systems can run software based MIDI emulators to still hear this sounds (modern Windows has one preinstalled that is invoked automatically when MIDI is played)

Sound effects work just fine, but there is no background music when running this game as it detects no MIDI devices. I need a way to get a software MIDI emulator running under Winlator, maybe even the default modern Windows one.
