+ | There are three ways how to output music on X68000 - Built-in sound, Roland LA sound source, Roland GS sound source. The Roland MT-32 MIDI synthesizer module, which was accepted as the industry standard for X68000, was introduced in 1987, the same year when the first X68000 came out. It used Linear Arithmetic synthesis to produce sound and saw several upgrades. The Roland SC-55 General Standard module, which was introduced in 1991, supported LA through emulation which was not accurate and thus noticeably degraded music quality. However, there are some games that take advantage of GS enhanced capabilities. | ||

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. It also features a digital reverberation effect. Successors (see below) added a library of 33 sound effects. Because of the absence of a piano attack sample, it cannot play a convincing acoustic piano sound. | 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.

Since the SC-55 has no programmable memory, CM-32P and MT-32 emulation is done by providing the same sound arrangement as the preset sounds of actual devices. These variation banks are enabled by playing back special SysEx containing MIDI files, for example GS32.MID (included in the SCC-1 Utility Software), prior to loading a software title. These specially arranged tone tables contain the relevant GS sound mapped at either CM-32P or MT-32 program number. Pitch bend range is changed to 12 semitone from GS default 2 semitones. Master tuning and modulation depth are not altered by the emulation. Pan directions are reversed from actual CM-32P or MT-32 devices. CM-32P or MT-32 specific MIDI SysEx messages are also ignored by the SC-55. | Since the SC-55 has no programmable memory, CM-32P and MT-32 emulation is done by providing the same sound arrangement as the preset sounds of actual devices.
