PRECAUTIONS
PLEASE READ CAREFULLY BEFORE PROCEEDING
* Please keep this manual in a safe place for future reference.
WARNING
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical
shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following:
• Only use the voltage specified as correct for the instrument. The required
voltage is printed on the name plate of the instrument.
•Use the specified adaptor (page 135) only. Using the wrong adaptor can result in
damage to the instrument or overheating.
•Check the electric plug periodically and remove any dirt or dust which may have
accumulated on it.
•Do not place the AC adaptor cord near heat sources such as heaters or radiators,
and do not excessively bend or otherwise damage the cord, place heavy objects
on it, or place it in a position where anyone could walk on, trip over, or roll
anything over it.
• Do not open the instrument or attempt to disassemble the internal parts or
modify them in any way. The instrument contains no user-serviceable parts. If it
should appear to be malfunctioning, discontinue use immediately and have it
inspected by qualified Yamaha service personnel.
• Do not expose the instrument to rain, use it near water or in damp or wet
conditions, or place containers on it containing liquids which might spill into
any openings. If any liquid such as water seeps into the instrument, turn off the
power immediately and unplug the power cord from the AC outlet. Then have
the instrument inspected by qualified Yamaha service personnel.
• Never insert or remove an electric plug with wet hands.
• Do not put burning items, such as candles, on the unit.
A burning item may fall over and cause a fire.
• If the AC adaptor cord or plug becomes frayed or damaged, or if there is a
sudden loss of sound during use of the instrument, or if any unusual smells or
smoke should appear to be caused by it, immediately turn off the power switch,
disconnect the adaptor plug from the outlet, and have the instrument inspected
by qualified Yamaha service personnel.
CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage
to the instrument or other property. These precautions include, but are not limited to, the following:
• When removing the electric plug from the instrument or an outlet, always hold
the plug itself and not the cord.
• Unplug the AC power adaptor when not using the instrument, or during
electrical storms.
•Do not connect the instrument to an electrical outlet using a multiple-connector.
Doing so can result in lower sound quality, or possibly cause overheating in the
outlet.
•Do not expose the instrument to excessive dust or vibrations, or extreme cold or
heat (such as in direct sunlight, near a heater, or in a car during the day) to
prevent the possibility of panel disfiguration or damage to the internal
components.
• Do not use the instrument in the vicinity of a TV, radio, stereo equipment,
mobile phone, or other electric devices. Otherwise, the instrument, TV, or radio
may generate noise.
• Do not place the instrument in an unstable position where it might accidentally
fall over.
• Before moving the instrument, remove all connected adaptor and other cables.
• When setting up the product, make sure that the AC outlet you are using is
easily accessible. If some trouble or malfunction occurs, immediately turn off
the power switch and disconnect the plug from the outlet. Even when the power
switch is turned off, electricity is still flowing to the product at the minimum
level. When you are not using the product for a long time, make sure to unplug
the power cord from the wall AC outlet.
• Use only the stand specified for the instrument. When attaching the stand or
rack, use the provided screws only. Failure to do so could cause damage to the
internal components or result in the instrument falling over.

• Before connecting the instrument to other electronic components, turn off the
power for all components. Before turning the power on or off for all
components, set all volume levels to minimum. Also, be sure to set the volumes
of all components at their minimum levels and gradually raise the volume
controls while playing the instrument to set the desired listening level.
• When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners,
solvents, cleaning fluids, or chemical-impregnated wiping cloths.
• Do not insert a finger or hand in any gaps on the instrument.
• Never insert or drop paper, metallic, or other objects into the gaps on the panel
or keyboard. If this happens, turn off the power immediately and unplug the
power cord from the AC outlet. Then have the instrument inspected by qualified
Yamaha service personnel.
• Do not place vinyl, plastic or rubber objects on the instrument, since this might
discolor the panel or keyboard.
•Do not rest your weight on, or place heavy objects on the instrument, and do not
use excessive force on the buttons, switches or connectors.
• Do not use the instrument or headphones for a long period of time at a high or
uncomfortable volume level, since this can cause permanent hearing loss. If you
experience any hearing loss or ringing in the ears, consult a physician.
Saving and backing up your data
• The panel settings and some other types of data are not retained in memory
when you turn off the power to the instrument. Save data you want to keep to the
Registration Memory (page 85).
Saved data may be lost due to malfunction or incorrect operation. Save
important data to a USB storage device/external device such as a computer
(page 98).
Backing up the USB storage device/external media
•To protect against data loss through media damage, we recommend that you
save your important data onto two USB storage devices/external media.
Always turn the power off when the instrument is not in use.
Even when the power switch is in the “STANDBY” position, electricity is still flowing to the instrument at the minimum level. When you are not using the instrument for a long
time, make sure you unplug the AC power adaptor from the wall AC outlet.

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.
XF
The Yamaha XF format enhances the SMF (Standard MIDI File) standard with greater functionality and
open-ended expandability for the future. The instrument is capable of displaying lyrics when an XF file con-
taining lyric data is played.
STYLE FILE
The Style File Format is Yamaha’s original style file format which uses a unique conversion system to pro-
vide high-quality automatic accompaniment based on a wide range of chord types.

Included here is information on how you can play the Styles in various ways, how to
adjust the Style volume, how you can play chords using the Styles, and more.
The instrument features a wide variety of Style “sections” that allow you to vary the arrangement of the
accompaniment to match the Song you are playing.
●INTRO section
This is used for the beginning of the Song. When the intro finishes playing, accompani-
ment shifts to the main section. The length of the intro (in measures) differs depending on
the selected Style.
●MAIN VARIATION section
This is used for playing the main part of the Song. It plays a main accompaniment pattern,
and repeats indefinitely until another section’s button is pressed. There are four variations
on the basic pattern (A–D), and the Style playback sound changes harmonically based on
the chords you play with your left hand.
●ENDING section
This is used for the ending of the Song. When the ending is finished, the Auto Accompani-
ment stops automatically. The length of the ending (in measures) differs depending on the
selected Style.
●AUTO Fill-in section

Style (Auto Accompaniment) Functions
PSR-S550 Owner’s Manual 61
Two or more notes played together constitute a “chord”.
The most basic chord type is the “triad” consisting of three notes: the
root, third, and fifth degrees of the corresponding scale. A C major
triad, for example, is made up of the notes C (the root), E (the third
note of the C major scale), and G (the fifth note of the C major scale).
In the C major triad shown above, the lowest note is the “root” of the
chord (this is the chord’s “root position” ... using other chord notes for the lowest note results in “inver-
sions”). The root is the central sound of the chord, which supports and anchors the other chord notes.
The distance (interval) between adjacent notes of a triad in root position is either a major or minor third.
The lowest interval in our root-position triad (between the root and the third) determines whether the
triad is a major or minor chord, and we can shift the highest note up or down by a semitone to produce
two additional chords, as shown below.
The basic characteristics of the chord sound remain intact even if we change the order of the notes to
create different inversions. Successive chords in a chord progression can be smoothly connected, for
example, by choosing the appropriate inversions (or chord “voicings”).
● Reading Chord Names
Chord names tell you just about everything you need to know about a
chord (other than the inversion/voicing). The chord name tells you what
the root of the chord is, whether it is a major, minor, or diminished
chord, whether it requires a major or flatted seventh, what alterations or
tensions it uses ... all at a glance.

This instrument features 11 internal Style categories, but it also allows you to import additional Styles
(only those with an “.sty” extension) that you’ve downloaded from the Internet or gotten from other
sources, and load them into a User Style and use them in the same way as the internal Styles.
For details on loading a Style file, see “
Loading Registration Files, Style Files, Song Files or MDB Files
”
on page
87
.
In order to load a Style file it is necessary to first either transfer the Style file to the instrument from a com-
puter, or connect a USB flash memory containing the Style file to the USB TO DEVICE connector. Refer to
“Transferring Data Between the Computer and Instrument” on page 96 for details on the file transfer proce-
dure.
If you are using a USB flash memory device, refer to “Loading Registration Files, Style Files, Song Files or
MDB Files” on page 87.
You can directly play the User Style in the USB memory without loading (page 89).
In “Playing Along with a Style” on page 23 we described two methods of playing Styles (Multi, Full Key-
board) in which chords were either detected only to the left of the keyboard Split Point or over the entire
keyboard. By making the settings described below, chord detection for Style accompaniment occurs over
the entire range of the keyboard, allowing for even more dynamic Style performance. In this mode only
chords played in the normal way (page 25) can be detected.

Using USB Flash Memory
USB flash memory is a memory medium used for storing data. When a USB flash mem-
ory device is inserted in this instrument’s USB TO DEVICE terminal, user Songs and
user Styles created on the instrument and the registered settings can be saved to or
loaded from the device. USB flash memory can also be used to transfer Song, Style
MDB data downloaded from the Internet to the instrument. Furthermore, user Songs
saved to USB flash memory in MIDI file format can also be used with these features.
In this section we’ll look at the procedures for setting up and formatting USB flash
memory devices, as well as for saving and loading data to and from them.
Before using a USB device, read through the “Precautions when using the [USB TO DEVICE] terminal”
section on page 93. For information about USB devices compatible with the instrument, see “Connection to
a USB Storage Device” on page 90.
1Connect a USB flash memory to the
USB TO DEVICE terminal, being careful
to insert it in the proper direction. (Do
not try to force an improper connec-
tion.)

needed).
The instrument does not necessarily support all commercially available USB storage
devices. Yamaha cannot guarantee operation of USB storage devices that you purchase.
Before purchasing a USB storage device, please consult your Yamaha dealer, or an autho-
rized Yamaha distributor (see list at end of the Owner’s Manual) for advice.

PSR-S550 Owner’s Manual 107
Troubleshooting
Problem Possible Cause and Solution
When the instrument is turned on or off, a popping
sound is temporarily produced.
This is normal and indicates that the instrument is receiving electrical
power.
When using a mobile phone, noise is produced.
Using a mobile phone in close proximity to the instrument may pro-
duce interference. To prevent this, turn off the mobile phone or use it
further away from the instrument.
There is no sound even when the keyboard is
played or when a song or style is being played
back.
Check that nothing is connected to the PHONES/OUTPUT jack on
the rear panel. When a set of headphones is plugged into this jack,
no sound is output.
Check the Local Control on/off. (See page 94.)
Is the FILE CONTROL display showing? The instrument’s keyboard,
etc., will not produce any sound while the FILE CONTROL display is
showing. Press the [EXIT] button to return to the MAIN display.
The style or song does not play back when the
[START/STOP] button is pressed.
Is External Clock set to ON? Make sure External Clock is set to OFF;
refer to “External Clock” on page 94.
The style does not sound properly.
Make sure that the Style Volume (page 81) is set to an appropriate
level.
Is the split point set at an appropriate key for the chords you are play-
ing? Set the split point at an appropriate key (page 59).
Is the [ACMP] button lit? If it is not lit, press the [ACMP] button so it
lights.
No rhythm accompaniment plays when the
[START/STOP] button is pressed after selecting
the BaroqueAir Style in the MOVIE & SHOW cate-
gory.
This is not a malfunction. Style BaroqueAir Style does not have a
Rhythm part, so there is no rhythm sound for this Style. Also, this
Style does not have a Fill-In section. The other parts will begin play-
ing when you play a chord in the accompaniment.
Not all of the voices seem to sound, or the sound
seems to be cut off.
The instrument is polyphonic up to a maximum of 32 notes. If the
Dual voice or Split voice is being used and a style or song is playing
back at the same time, some notes/sounds may be omitted (or “sto-
len”) from the accompaniment or song.
The footswitch (for sustain) seems to produce the
opposite effect. For example, pressing the
footswitch cuts off the sound and releasing it sus-
tains the sounds.
The polarity of the footswitch is reversed. Make sure that the
footswitch plug is properly connected to the SUSTAIN jack before
turning on the power.
The sound of the voice changes from note to note.
This is normal. The AWM tone generation method uses multiple
recordings (samples) of an instrument across the range of the key-
board; thus, the actual sound of the voice may be slightly different
from note to note.
The Demo display is shown in Japanese, and/or
there are Japanese characters in the display mes-
sages.
Make sure the Language setting in the FUNCTION display is set to
English. (See page 12)
The ACMP indicator does not appear when the
[ACMP] button is pressed.
Always press desired style category button first when you are going
to use any style-related function.
There is no harmony sound.
The harmony effects (01–26) behave differently according to their
type. Types 01–05 function when style playback is on, chords are
played in the accompaniment range of the keyboard, and a melody is
played in the right-hand range. Types 06–26 will function whether
style playback is on or off. For types 06–12 you need to play two
notes at the same time.

Voice List
■Maximum Polyphony ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ●
The instrument has 64-note maximum polyphony. This means
that it can play a maximum of up to 64 notes at once, regard-
less of what functions are used. Auto accompaniment uses a
number of the available notes, so when auto accompaniment
is used the total number of available notes for playing on the
keyboard is correspondingly reduced. The same applies to the
Split Voice and Song functions. If the maximum polyphony is
exceeded, earlier played notes will be cut off and the most
recent notes have priority (last note priority).
●Panel Voice List
•The Voice List includes MIDI program change numbers for
each voice. Use these program change numbers when
playing the instrument via MIDI from an external device.
• Program Numbers 001 to 128 directly relate to MIDI Pro-
gram Change Numbers 000 to 127. That is, Program Num-
bers and Program Change Numbers differ by a value of 1.
Remember to take this into consideration.
• Some voices may sound continuously or have a long
decay after the notes have been released while the sus-
tain pedal (footswitch) is held.
