Software Music Synthesis System

The Software Music Synthesis System, which, despite its name, was a hardware device, was developed in the late 1970s for use on various 8080 or Z-80 platforms under the then-popular S-100 bus, such as the SOL-20. Its accompanying software worked under various cassette and disk operating systems, including CP/M. Its format for defining musical pieces to be played on the hardware involved sequences of ASCII characters defining characteristics of notes.
