But I'd think a good number of notation programs use MIDI for their audio output and with abc, abc2midi is a standard utility...

Of course the sound you get from MIDI devices varies tremendously and there is no knowing what a MIDI's going to sound like on someone else's PC. In cases such as Joe's where the aim is just to convey how a tune goes, it doesn't really matter but there may also be cases where you want to record the sound output you are getting.

Just as a curiosity item and only chosen as I downloaded it from Mudcat Midi while I was playing with Midi Voyager on my phone but this is what I get from the phone with the suggested sound font installed. This goes through my keyboard and would be closer to what I'd attempted when I had the Yamaha daughter board...
