Interesting. From around 1975 or so, and worth learning about is the
music synthesizer developed on the PLATO system at the University of
Illinois by Sherwin Gooch. The hardware is described in great detail
(including full schematics) in US Patent 4,206,675. The software
includes
a music code compiler, using a code somewhat like
the one you referenced
but different in details. I don't know if one borred from the other or
if
they are independent inventions. (Sherwin might
remember.)
A few years later PLATO added a 16 channel waveform synthesis device,
controlled by the microprocessor in the terminals. It had a similar
music
code, plus support for a piano keyboard (with key
velocity sensing) for
music input with real time display of the score, as well as score
printing. Not long after, Lippold Haken created a keyboard that's
continuous rather than discrete (think of a keyboard like the fingerboard
of a violin); a successor of that is still sold today.
I'd be very interested in any sound samples, if anyone has any...I guess
that's perhaps unlikely. And on that note (heh), are there any other
computer music albums out there? I know of the First Philadelphia Computer
Music Festival, the two Unplayed by Human Hands, and it looks like the
University of Melbourne had an electronic music album too. There's a 45
entitled Computer Composites that featured several IBM systems,
I'm finding it rather difficult to find LPs that are assuredly produced by
a digital computer versus by other electronic means, like early
synthesizers, etc.
I have an LP, "Electronic Music from the University of Illinois" (1967 or
so):

If I recall, they used the U of I's ILLIAC IV in the recording.
It's somewhat interesting but the electronic parts of it are sometimes hard
to discern :). Looks like someone's digitized it here:

I digitized an 45 of music generated by an Orchestra-80 (TRS-80 4-channel
synth), it's called "Classical Mosquito!" -- you can grab it from here:

As an aside, I've been (slowly) working on emulating Ted Kaehler's organ
keyboard / FM synth for the Xerox Alto (c. 1974) in ContrAlto. I have just
enough technical information and code listings to make it possible, but
there's just enough information missing to make it difficult...

Thanks, Al, for the scan upload! I've enjoyed reading that.
