General MIDI
General MIDI is a set of recommendations which seeks to provide a way to go beyond the limitations of
proprietary designs, and standardize the MIDI capabilities of sound generating devices. Sound generating devices
and music files that meet the General MIDI standard bear the General MIDI logo. Music files bearing the General
MIDI logo can be played back using any General MIDI sound generating unit to produce essentially the same musical
performance.
General MIDI 2
The upwardly compatible General MIDI 2 recommendations pick up where the original General MIDI left
off, offering enhanced expressive capabilities, and even greater compatibility. Issues that were not covered by the orig-
inal General MIDI recommendations, such as how sounds are to be edited, and how effects should be handled, have
now been precisely defined. Moreover, the available sounds have been expanded. General MIDI 2 compliant sound
generators are capable of reliably playing back music files that carry either the General MIDI or General MIDI 2 logo. In
some cases, the conventional form of General MIDI, which does not include the new enhancements, is referred to as
‘‘General MIDI 1’’ as a way of distinguishing it from General MIDI 2.
SMF with Lyrics
‘‘SMF with Lyrics’’ refers to SMFs (Standard MIDI Files) that contains lyrics. When Music Files carrying the ‘‘SMF
with Lyrics’’ logo are played back on a compatible device (one bearing the same logo), the lyrics will appear in its display.
GS Format
The GS Format is Roland’s set of specifications for standardizing the performance of sound-generating
devices. In addition to including support for everything defined by General MIDI, the highly compatible GS Format
additionally offers an expanded number of sounds, provides for the editing of sounds, and spells out many details for
a wide range of extra features, including effects such as reverb and chorus. Designed with the future in mind, the GS
Format can readily include new sounds and support new hardware features when they arrive. Since it is upwardly com-
patible with General MIDI, Roland’s GS Format is capable of reliably playing back GM Scores equally as well as it per-
forms GS music files (music files that have been created with the GS Format in mind). This product supports both the
General MIDI 2 and the GS Format, and can be used to play back music data carrying either of these logos.
XG lite
XG is a tone generator format of YAMAHA Corporation that defines the ways in which voices are expanded
or edited and the structure and type of effects, in addition to the General MIDI 1 specification. XGlite is a simplified ver-
sion of XG tone generation format. You can play back any XG music files using an XGlite tone generator. However, keep
in mind that some music files may play back differently compared to the original files, due to the reduced set of con-
trol parameters and effects.
