The MT-32 by default assigns its parts 1~8 and R(hythm) to respond on input MIDI channels 2~9 and 10 respectively. With 32 partials available overall, polyphony depends on the tonal complexity of the music, and 8 to 32 notes can be played simultaneously. Sounds are created from up to 4 partials which can be combined in various ways (including ring modulation).
Because of the absence of a piano attack sample, it cannot play a convincing acoustic piano sound.
Successors (see below) added a library of 33 sound effects. It also features a digital reverberation effect. The original MT-32 comes with a preset library of 128 synth and 30 rhythm sounds, playable on 8 melodic channels and one rhythm channel. Samples are used for attacks and drums, while traditional synthesis assures the sustain phase of the sounds. Like the Roland D-50 Linear Synthesizer, it uses Linear Arithmetic synthesis, a form of sample-based synthesis combined with subtractive synthesis, to produce its sounds. It was the first product in Roland's Myuujikun ( ミュージくん) line of Desktop Music System (DTM) packages in Japan. 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 monotimbral D-50 and D-550 models are for sophisticated multi-track studio work. Since it was made prior to the release of the General MIDI standard, it uses its own proprietary format for MIDI file playback. However, it became more famous along with its compatible modules as an early de facto standard in computer music. It was originally marketed to amateur musicians as a budget external synthesizer with an original list price of $695. The Roland MT-32 Multi-Timbre Sound Module is a MIDI synthesizer module first released in 1987 by Roland Corporation.
