Roland SC-55 Sound Canvas

The Roland SC-55 Sound Canvas is a MIDI sound module released by Roland Corporation in 1991. It was the first module in the Sound Canvas series and was the first MIDI module to feature built-in wavetable synthesis. It was used by many musicians and producers in the 1990s and is still popular today.

The SC-55 works by receiving MIDI data from a connected MIDI controller or sequencer and then playing back the corresponding sound. It has a built-in library of sounds, including drums, bass, strings, brass, and more. It also has a variety of effects, such as reverb, chorus, and delay. Additionally, it has a built-in sequencer for creating and playing back MIDI sequences.
