There's at least one exception to that. In an early-19th c. French
book about the proper pinning of barrel organs, there's a detailed
illustration of the pinning for a barrel to play the overture to "The
Marriage of Figaro." When the illustration is transcribed into MIDI
and played back, the music turns out to be in very distinct (and
rapid) notes inégales.
Fascinating. Do you know where I could find a copy of that MIDI file?
I was speaking very loosely. The research I mentioned was done in the
1970s by David Fuller, who published an article on it at the time.
Accordingly, the computer work involved can't have been MIDI, but an
earlier type of music sound synthesis, working from an intermediate
stage in which the measurements from the pinning diagram were converted
into numbered pitches and durations. The resulting sound "file" would
have been a reel-to-reel tape, recorded from the playback of a stack of
punch cards. The tape may well have totally decayed by now.
The inequality was applied at the sixteenth note level, the weak notes
being just a tiny bit longer than 1/2 the duration of the strong notes.
