Digital Effects
• A comprehensive set of professional-sounding digital
effects are built into the PSR-550, letting you enhance the
sound of your performance in a wide variety of ways.
These include Reverb, Chorus, DSP and Harmony/Echo.
( Page 46)
* Reverb recreates the rich spacial ambiance of various
performance environments, such as a concert hall or a
night club. ( Page 46)
* Chorus enriches the voices by making them sound
warmer and thicker — as if several instruments were
playing together at the same time. (
* The DSP effects let you process the sound in special,
unusual ways — such as applying distortion or tremolo
to a specific part. ( Page 49)
* Harmony/Echo lets you enhance your right-hand
melodies with a variety of harmony and echo effects.

Disk Drive
• The PSR-550 also features a built-in disk drive that lets
you save all your important original data (such as User
songs, User styles, User Multi Pads, Registration Memory,
etc.) to floppy disk for future recall. (

Panel logos

The logos printed on the PSR-550 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-550'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-550 uses the SFF internally, reads
optional SFF style disks, and creates SFF styles using the
Style Recording feature.

• MIDI (Musical Instrument Digital Interface) is a worldwide
standard interface that allows various electronic music
instruments, computers and other devices to communi-
cate with each other. The MIDI features let you
seamlessly integrate the PSR-550 into a variety of
