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 music. Since it was made prior to the release of the General MIDI standard, it uses its own proprietary format for MIDI file playback.
Two major revisions of the MT-32 were produced. Roland refers to them as MT-32 (Old / Without headphones) and MT-32 (New / With headphones).
The LA32 sound generation chip is an 80-pin PGA. The control CPU is an Intel C8095-90 in ceramic DIP-48 package. The digital-to-analog converter (DAC) is a Burr-Brown PCM54; the input signal having a resolution of 15 bits (see below). Line-outs are unbalanced 1/4″ TS phone connector (separate left and right channels.) No headphone jack.
The PGA LA32 chip is later replaced with a 100-pin QFP type.
The control CPU is an Intel P8098. Same DAC, but with 16 bits of input signal resolution (see below). A stereo 1/4″ TRS headphones jack is added.
MT-32 compatible models
To target computer users, Roland released a number of CM (Computer Music) modules. They came without a LCD display and had most buttons removed. CM modules are compatible with MT-32, but feature 33 additional sound effect samples which many games took advantage of. These sound effects cannot be heard on a MT-32. Early models share a similar design to MT-32 (New). Control CPU is an Intel P8098 and DAC is a Burr-Brown PCM54.
In later models, the DAC is a Burr-Brown PCM55, and vibrato is noticeably faster.
|Engine Detailed||Digital LAS (Linear Arithmetic Synthesis) & PCM. 4 OSC (partials). Combines traditional subtractive synthesis with PCM-based samples. 1 voice can combine up to four partials in various configurations with or without ring modulation. Two LA and Two PCM samples max only.|
|Memory||128 synth presets, 64 volatile programmable|
|Drums||28 rhythm presets. 1Kit, 30 sounds|
|Extra info||MT-32 desktop model has keys and volume dial to adjust parameters. CM-range has none (aimed for use with Computers and sequencing software)|
|Produced:||1987 - 1993|
|Legend:||Obvious||Y: Yes, N: No, N/A: Not Applicable|
|VCO||Voltage Controlled Oscillator||DCO||Digital Controlled Oscillator|
|LFO||Low Frequency Oscillator||Sub||Sub Oscillator|
|VCF||Voltage Controlled Filter||VCA||Voltage Controlled Amplifier|
|Velocity||As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key.||Aftertouch||Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.|
|Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.|
