VL Extension for XG

The VL Extension for XG ("VL Extension for XG" is
abbreviated to VL-XG) included in the VL70-m Virtual
Acoustic Tone Generator significantly enhances and
expands the musical capabilities of the XG format with
the superior sound and expressive potential of Yamaha Virtual Acoustic
Synthesis. A VL70-m can be used in conjunction with a Yamaha MU80
or MU50 XG tone generator, for example: the VL70-m providing supe-
rior wind and string instrument voices while the MU80 or MU50 supplies
drums, percussion, keyboard, and other voices.
The XG format is basically a set of rules describing how a tone generator
will respond to MIDI data. The current GM (General MIDI) format is a
similar concept, allowing GM music data to be reproduced accurately on
any GM tone generator from any manufacturer. GM, however, applies
only to a limited set of parameters. XG significantly expands on the basic
GM format, providing many more voices, voice editing capability,
effects, external input, and other features that contribute to enhanced
musical expression. And since XG is totally upward compatible with GM,
GM data can be accurately reproduced on any XG tone generator.
* The VL70-m does not contain the basic set for the XG format.
