The Roland SC-88 ( Sound Canvas) is a General MIDI GS-compatible sound module released in 1994 by Roland Corporation. It is the second sound module released for the Roland Sound Canvas series. Being released as the successor to the SC-55, it retains the same PCM synthesis but expands upon the SC-55 in several aspects. The SC-88 had roughly double the instrument count previously present in the SC-55, having 654 patches, also adding new drum kits, including 2 SFX sets. It also had upgraded to 64-voice polyphony as well as doubling the previously 16 parts to 32 parts.

The SC-88 featured backwards compatibility with the SC-55, coming in preloaded with soundsets from the SC-55/SC-55 mkII, allowing for near-perfect compatibility for songs made with the SC-55 or SC-55 mkII.

More effects were added, offering 8 types of reverb and chorus, as well as introducing 10 different types of a new delay effect and 2-band EQ, which could have their parameter tweaked on a base SC-88.

The base model, it allowed for users to create up to 256 user instruments and 2 drum kits or edit the stock patches

SC-88VL - cost-effective version of the SC-88 with user programming removed

SC-88ST - Playback-only version of the Sc-88, also much cheaper i assume
