Roland SC-55

Unlike its predecessor, the SC-55 only uses PCM synthesis[citation needed], supporting up to 24-voice polyphony with 16-part multitimbrality.

[1] Aimed at PC music enthusiasts, the SC-55 featured 315[1] instrument patches, including the GS drum kits and additional controllers.

Roland later replaced the SCC-1 with a combination of their MPU-401AT MIDI interface card and SCB-55 Wave Blaster-compatible daughterboard.

These specially arranged tone tables contain the relevant GS sound mapped at either CM-32P or MT-32 program number.

[1] This results in poor emulation for software relying on custom programmable MT-32 sounds, as demonstrated by the introduction of the Sierra On-Line game Space Quest III: The Pirates of Pestulon.

Emulation for software supporting the Roland MT-32 but not using its memory is better, as demonstrated by the introduction song from Origin Systems' Ultima VI: The False Prophet.

[citation needed] Video game musicians also used it to write their MIDI soundtracks, most famously in Doom (1993).
