Compatible Format and Functions
GM System Level 1
“GM System Level 1” is an addition to the MIDI standard which ensures that any GM-com-
patible music data can be accurately played by any GM-compatible tone generator,
regardless of manufacturer. The GM mark is affixed to all software and hardware products
that support GM System Level.
XGlite
As its name implies, “XGlite” is a simplified version of Yamaha’s high-quality XG tone gen-
eration format. Naturally, you can play back any XG song data using an XGlite tone gener-
ator. However, keep in mind that some songs may play back differently compared to the
original data, due to the reduced set of control parameters and effects.
USB
USB is an abbreviation for Universal Serial Bus. It is a serial interface for connecting a
computer with peripheral devices.
STYLE FILE FORMAT (SFF)
The Style File Format is Yamaha’s original style file format which uses a unique conversion
system to provide high-quality automatic accompaniment based on a wide range of chord
types.
