Roland AT 5 用户手册

The ATELIER series come equipped with GM2/GS sound 

generators.

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.

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.

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” 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.

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. XG lite is a simplified version of XG 

tone generation format. You can play back any XG music 

files using an XG lite 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.
