Roland MT-32

Roland MT-32 is a budget LA synthesis module, primarily used for computer games. It was released in 1987.

As it was released before General MIDI started, it uses its own order of instruments. Channels 2 to 9 can be used, channel 10 is exclusively used for drums, and the rest of the channels cannot be used.

Additionally, SysEx can be used to edit the instrument patches.

The Roland CM-32L is a notable MT-32 variant, removing the controls and display but adding sound effects.
