The Roland SC-55 Sound Canvas is a legendary General MIDI sound module introduced in 1991 by Roland. Widely regarded as one of the most influential MIDI modules ever produced, the SC-55 was the first device to fully implement the General MIDI (GM) standard, making it a cornerstone of early computer music, MIDI sequencing, and game soundtracks.
Part of the iconic Sound Canvas series, the SC-55 delivers a wide palette of classic MIDI instrument sounds including pianos, strings, brass, synths, drums, and orchestral voices. It became the reference module for countless MIDI files throughout the 1990s and remains highly sought after by producers, collectors, retro gaming enthusiasts, and MIDI composers looking for authentic General MIDI playback.
This unit is being sold AS IS for parts or repair. It appears to power on, but it has not been fully tested due to the absence of a power supply.
