The Roland SC-7 General MIDI Sound Module is a stand-alone MIDI synthesizer module by Roland Corporation. It was released in 1992. It supports the General MIDI System and can also be used as a MIDI interface for a computer. The Roland SC-7 provides the basic (capital) Roland Sound Canvas sounds in a compact design for stand-alone, IBM PC/AT or Apple Macintosh computer use.
The SC-7 is 16-part multitimbral with 28-voice polyphony. Individual sounds use one or two voices. It complies to the General MIDI System Level 1 Specification with 128 sounds, 6 drum sets (derived from GS drum sets) digital reverb/delay and chorus effects. The Roland SC-7's ROM samples sound similar with other Roland Sound Canvas and other Roland products from the same era, for example, the Roland SCC-1, the Roland SC-55, the Roland XP-10 synthesizer, and the Roland E-Series Intelligent Keyboard lineup.
The SC-7 has two audio inputs (one with level adjust) to mix two different audio sources, for example, a D/A converter (a computer sound card) or an external CD-player together with the SC-7's own output all at the sound module's audio output, making it easy to connect to amplification or speaker devices.
The Roland SCB-7 was a Roland MIDI Daughterboard version of the SC-7 that plugged into the Wave Blaster Connector of the Sound Blaster line of sound cards for the PC. The Roland RAP-10 was an ISA sound card with the SC-7 on board along with digital sampling.

Use in media
The "Standard" drum set of the Roland SC-7 (or other similar Roland product) can be recognized in various (low-budget) television or music productions.
The SC-7, along with other Roland Sound Canvas products are one of the popular choices of MIDI instruments used to generate instrumental elevator music, as well as MIDI-based background music for various television test pattern sequences.
