Voice Allocation Format
With MIDI, voices are assigned to specific numbers,
called “program numbers.” The numbering standard
(order of voice allocation) is referred to as the “voice
allocation format.”
Voices may not play back as expected unless the voice
allocation format of the song data matches that of the
compatible MIDI device used for playback.
The CVP-209/207 is compatible with the following
formats.
■ GM System Level 1
This is one of the most common voice allocation formats.
• Many MIDI devices are compatible with GM System
Level1, as is most commercially available software.
■ XG
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.
• Song data recorded on the CVP-209/207 using voices
in the [XG] category is XG-compatible.
■ DOC
This voice allocation format is compatible with many of
Yamaha’s MIDI devices, including the Clavinova series
instruments.This is also a common format used with
various Yamaha software.
Even if the devices and data used satisfy all the conditions above,
the data may still not be completely compatible, depending on the
specifications of the devices and particular data recording
methods.
