Music stand
The PSR-9000 is supplied with a music stand that can be attached to the
instrument by inserting it into the holes at the rear of the speaker panel.
The logos printed on the PSR-9000 panel indicate the standards/formats it supports and
special features it includes.
GM System Level 1
GM System Level 1 is an addition to the MIDI standard which guarantees that any data
conforming to the standard will play accurately on any GM-compatible tone generator
or synthesizer from any manufacturer.
XG
XG is a new Yamaha MIDI specification which significantly expands and improves on
the GM System Level 1 standard with greater voice handling capacity, expressive con-
trol, and effect capability while retaining full compatibility with GM. By using the PSR-
9000’s XG voices, it is possible to record XG-compatible song files.
XF
The Yamaha XF format enhances the SMF (Standard MIDI File) standard with greater
functionality and open-ended expandability for the future. The PSR-9000 is capable of
displaying lyrics when an XF file containing lyric data is played.
Vocal Harmony
Vocal Harmony employs state-of-the-art digital signal processing technology to auto-
matically add appropriate vocal harmony to a lead vocal line sung by the user. Vocal
Harmony can even change the character and gender of the lead voice as well as the
added voices to produce a wide range of vocal harmony effects.
DOC
The DOC voice allocation format provides data playback compatibility with a wide
range of Yamaha instruments and MIDI devices, including the Clavinova series.
Style File Format
The Style File Format — SFF — 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. The PSR-9000 uses the SFF internally, reads optional
SFF style disks, and creates SFF styles using the Style Creator function.
