You mean "Square wave synthesizer" vs "hardware wavetable synthesizer"
isn't a useful designation anymore?  ;)

Right - but remember I'm talking about the MIDI *output device*
manufacturer/product ID - so it would be "MOTU/MIDI Express XT", not
"Korg/MicroKorg".  Note I'm borrowing these concepts from the Windows MIDI
API, e.g.

.
