Formats
“GM (General MIDI)” is one of the most common Voice allocation formats. “GM System Level 2” is a standard specification
that enhances the original “GM” and improves Song data compatibility. It provides for increased polyphony, greater Voice
selection, expanded Voice parameters, and integrated effect processing.
XG is a major enhancement of the GM System Level 1 format, and was developed by Yamaha specifically to provide more
Voices and variations, as well as greater expressive control over Voices and effects, and to ensure compatibility of data well
into the future.
GS was developed by the Roland Corporation. In the same way as Yamaha XG, GS is a major enhancement of the GM spe-
cifically to provide more Voices and Drum kits and their variations, as well as greater expressive control over Voices and
effects.
The Yamaha XF format enhances the SMF (Standard MIDI File) standard with greater functionality and open-ended expand-
ability for the future. This instrument is capable of displaying lyrics when an XF file containing lyric data is played.
“SFF (Style File Format)” is an original Style file format by Yamaha which uses a unique conversion system to provide high-
quality automatic accompaniment based on a wide range of chord types. “SFF GE (Guitar Edition)” is an enhanced format of
SFF, which features improved note transposition for guitar tracks.
