Appendix
With MIDI, voices are assigned to specific num-
bers, 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.

GM System Level 1 (
logo
)
This logo (GM logo) is affixed to tone generators
and music data that supports “GM system level
1.”
“GM system level 1” is a standard specification
for the sound map and MIDI functionality of a
tone generator, and is designed to ensure that
music data will produce essentially identical
playback on tone generators from different man-
ufacturers or models.
• Many MIDI devices are compatible with GM
System Level 1, as is most commercially avail-
able software.
• The P-250 is compatible with GM System
Level 1.
■
XG (
logo
)
This logo (XG logo) appears on tone generators
and music data that supports “XG.”
XG is Yamaha’s tone generator format that
extends “GM system level 1” to allow richer
expressive power and future data compatibility.
• The P-250 is compatible with XG.
• Performance data recorded with preset voices
on the P-250 can be played on other XG-com-
patible instruments.
