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.
