■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 superior 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.
