The Roland MT-32 or Multi-Timbre - 32 sound module was originally marketed to amateur musicians as a budget synthesizer with an original list price of $695. However, Sierra On-Line, wanting to push the limits of multimedia support, took an interest in the Roland MT-32, and decided to utilize the synthesizers potential, even to the point of distributing the MT-32 themselves. This led to the MT-32 becoming popular in the PC gaming market. The MT-32 had a much higher quality sound than the competing AdLib and Sound Blaster cards of the day, especially in regards to percussion and brass instruments. However, the Roland MT-32 was considerably more expensive than other sound devices, so few could afford to experience the richness of its sound. In 1990, Sierra was selling the Game Blaster for $130, the AdLib for $175 ($245 with AdLib Visual Composer, the Sound Blaster for $240, the LAPC-I for $425, and the MT-32 for $550 ($650 with a MIDI micro channel). Also, unlike the Sound Blaster, the Roland MT-32 didn't have a DAC, so it could not process PCM audio making it terrible for sound effects, and useless for voice.

There were three generations of Roland MT-32s, each one upgraded the synthesizer and fixed problems with the earlier models. The original design used an 80-pin LA32 sound chip and an Intel C8095-90 CPU. It did not have a headphone jack and the line-out plugs were slightly unbalanced. The second version used a 100-pin LA32 sound chip with the same CPU. The third version switched the CPU to an Intel P8098 and added a 1/4" headphone jack.

The capabilities of the MT-32 were re-created in the CM-32L, CM-64, LAPC-I, LAPC-N, and the MT-100.

The Roland MT-32 was made prior to the creation of General MIDI, so it uses a proprietary MIDI structure. The most important difference between MT-32 and GM is the different instrument list.

Because of these different instrument mappings, games that play General MIDI through the MT-32 will play the wrong instruments. For example the main theme of Ultima Underworld II (DOS) will have its harmonious "cello 2" solo replaced by a cacophonous series of orchestra hits.

Other differences exist, such as the MT-32's support for reprogramming sounds. For this reason, merely translating instrument number values to their closest GM equivalent, or using an MT-32 soundfont, is often not enough to faithfully emulate the MT-32 sound.

Emulation Status

The project MUNT, which is incorporated in ScummVM and in foobar2000's MIDI Decoder, although unfinished, is the most accurate MT-32 emulator available. However, it requires ROM images from the original MT-32 in order to work.
