About ATELIER Series Sound
Generator
The ATELIER series come equipped with GM2/GS sound
generators.
General MIDI
The 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 meets the General MIDI standard bears 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 General MIDI 2 is a set of recommended specifications
that provide detailed definitions for functionality such as
sound editing and effects that had not been defined in the
General MIDI, and extend the sound map to allow a higher
degree of performance expression and compatibility. Since
the General MIDI 2 is compatible with the General MIDI, it is
capable of reliably playing back music files bearing the
General MIDI logo.
GS format
The GS Format is Roland’s set of specifications for standard-
izing the performance of sound generating devices. In
addition to including support for everything defined by the
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 compatible with the General MIDI,
Roland’s GS Format is capable of reliably playing back GM
Scores equally as well as it performs GS music files (music
files that have been created with the GS Format in mind).
This product supports both the General MIDI and the GS
Format, and can be used to play back music data carrying
either of these logos.
SMF with Lyrics
“SMF with Lyrics” refers to SMF (Standard MIDI File) that
contains the lyrics. When music files carrying the “SMF with
Lyrics” logo are played back on a compatible device (one
bearing the same logo), the lyrics appears in its display.
XGlite
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 version 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 control parameters
and effects.
