Roland MT-32

The Roland MT-32 Multi-Timbre Sound Module is a MIDI synthesizer module first released in 1987 by Roland Corporation. It was originally marketed to amateur musicians as a budget external synthesizer with an original list price of $695. However, it became more famous along with its compatible modules as an early de facto standard in computer multimedia. Since it was made prior to the release of the General MIDI standard, it uses its own proprietary instruments for MIDI file playback, as well as SysEx messages.

Within Roland's family of linear arithmetic (LA) synthesizers, the multitimbral MT-32 series constitutes the budget prosumer line for computer music at home, the multitimbral D-5, D-10, D-20 and D-110 models constitute the professional line for general studio use, and the high-end bitimbral D-50 and D-550 models are for sophisticated multi-track studio work. It was the first product in Roland's Myuujikun (ミュージくん) line of Desktop Music System (DTM) packages in Japan.
