The Roland SC-55 (Sound Canvas) is a GS MIDI sound module released in 1991 by Roland. The SC-55 was the first sound module to incorporate the new General MIDI standard. It was the first in the Roland Sound Canvas series. Alongside the SC-55, Roland released the (Sound Brush), an inexpensive MIDI sequencer module the same size as the Sound Canvas. Both the Sound Canvas and Sound Brush could be rackmounted alongside each other.
