Important Features
Panel logos
The logos printed on the PSR-540 panel indicate 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
control and effect capability while retaining full compatibility with GM. By using the
PSR-540’s XG voices, it is possible to record XG-compatible song files.
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-540 uses the SFF internally, reads optional SFF
style disks, and creates SFF styles using the Style Recording feature.

• A comprehensive set of professional-sounding digital
effects are built into the PSR-540, letting you enhance the

warmer and thicker — as if several instruments were
playing together at the same time. (
