About ATELIER Series Sound
Generator
The ATELIER series come equipped with GM2/GS sound
generators.
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
original 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.
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.
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
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.
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.
