Software Technology System
The Software Technology Music System is principally a software based system with a small board that plugs into a SOL-20 computer with 8K or more memory. Sheet music is programmed in using a high-level language called “Music.” The synthesizer has a bit more than a 4-octave range and can play three voices simultaneously. It provides no control over the amplitude or envelope of the notes although it does provide for staccato notes, various articulation times, durations and tempos. Each board provides output to only one channel, so for stereo, two boards are required. Yankee Doodle Dandy on this record is in monaural.
