Do not use the instrument near other electrical products such as televisions, radios, or speakers, since this might cause interference which can affect proper operation of the other products. 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 cleaning the instrument, use a soft, dry cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-impregnated wiping cloths. Also, 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. 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. Do not operate the instrument 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.
sDATA BACK-UP AND STORAGE
Yamaha recommends that you regularly save data using a floppy disk in a safe, cool, dry place. YAMAHA CANNOT BE HELD RESPONSIBLE FOR THE ACCIDENTAL LOSS OF IMPORTANT MUSIC DATA! Regarding the data you have created, as long as fresh batteries are inserted in (or an AC power adaptor is connected to) the instrument, the data will be retained, even when the power is turned off. It will also be retained long enough to exchange an old set of batteries for a new set. If you have important data in the instrument which you dont want to lose, please take care to keep fresh batteries inserted in (or keep an AC power adaptor connected to) the instrument, and to regularly save data.
Yamaha cannot be held responsible for damage caused by improper use or modifications to the instrument, or data that is lost or destroyed.
Always turn the power off when the instrument is not in use. Make sure to discard used batteries according to local regulations.

Congratulations!

You are the proud owner of a fine electronic keyboard. The Yamaha PSR-550 PortaTone combines the most advanced tone generation technology with state-of-theart digital electronics and features to give you stunning sound quality with maximum musical enjoyment. A large graphic display and easy-to-use interface also greatly enhance the operability of this advanced instrument. In order to make the most of your PortaTones features and extensive performance potential, we urge you to read the manual thoroughly while trying out the various features described. Keep the manual in a safe place for later reference.

Packing List

Please check that these items have been packed with your PSR-550.

Make sure that the STANDBY/ON switch of the PSR-550 is set to STANDBY. Connect the AC adaptor (PA-6 or other adaptor specifically recommended by Yamaha) to the power supply jack. Plug the AC adaptor into an AC outlet.
Never interrupt the power supply (e.g. remove the batteries or unplug the AC adaptor) during any PSR-550 record operation! Doing so can result in a loss of data.
Use ONLY a Yamaha PA-6 AC Power Adaptor (or other adaptor specifically recommended by Yamaha) to power your instrument from the AC mains. The use of other adaptors may result in irreparable damage to both the adaptor and the PSR-550. Unplug the AC Power Adaptor when not using the PSR-550, or during electrical storms.
When turning the power OFF, simply reverse the procedure.

s Using Batteries

For battery operation the PSR-550 requires six 1.5V D size, R20P (LR20) or equivalent batteries. When the batteries need to be replaced, Battery Low may appear on top of the display, the volume may be reduced, the sound may be distorted, and other problems may occur. When this happens, turn the power off and replace the batteries. Replace the batteries as follows:
When the batteries run down, replace them with a complete set of six new batteries. NEVER mix old and new batteries. Do not use different kinds of batteries (e.g. alkaline and manganese) at the same time. If the instrument is not to be in use for a long time, remove the batteries from it, in order to prevent possible fluid leakage from the battery. Plugging or unplugging the AC power adaptor while the batteries are installed will reset the PSR-550 to the defaults.
Open the battery compartment cover located on the instruments bottom panel. Insert the six new batteries, being careful to follow the polarity markings on the inside of the compartment. Replace the compartment cover, making sure that it locks firmly in place.
Important Notes on Battery Use
Since the PSR-550 consumes a considerable amount of power, Yamaha recommends the use of an AC power adaptor rather than batteries. The batteries should be considered an auxiliary power source for data backup. The floppy disk drive, in particular, uses a large amount of power, so it is important to always use an AC power adaptor when performing disk-intensive operations such as song recording/playback or data

The point on the keyboard that separates the auto accompaniment section and the righthand section of the keyboard is called the split point. When the auto accompaniment is on, keys played to the left of the split point are used for controlling the auto accompaniment (page 33). When the auto accompaniment is off, keys played to the left of the split point are used for playing voice L (page 28).
The default setting (factory setting) is F#2.

Split Point =C3

Touch Sensitivity
The keyboard of the PSR-550 is equipped with a touch response feature that lets you dynamically and expressively control the level of the voices with your playing strength just as on an acoustic instrument. The Touch Sensitivity parameter gives you detailed control over the touch response feature by letting you set the degree of touch response.

Touch Sense =127

Set the value with the data dial, the [+/YES] button, the [-/NO] button or the number buttons [1]-[0]. The range is from 0 to 127. The greater the value, the more sensitive the keyboard is to your playing strength, and the more dynamic range that can be brought out of the voices. A setting of 0 results in a fixed touch response, or no level change no matter how hard or how soft you play the keys. (This setting is good for instrument sounds such as organ or harpsichord, which normally do not have touch response.) You can also achieve the same effect by turning touch response off with the [TOUCH] button on the panel (the indicator turns off).

Voice Set

The Voice Set feature brings out the best in each individual voice by automatically setting a range of important voice-related parameters whenever an R1 panel voice is selected. The parameters that may be set by the Voice Set feature are listed below. This function lets you turn Voice Set on or off, as required.

Auto accompaniment chords are recognized regardless of the split point or where chords are played on the keyboard. The Harmony function does not operate.
MIDI data is not transmitted or received, even when MIDI cables are connected properly.
Data Backup & Initialization

s Data Backup

Except for the data listed below, all PSR-550 panel settings are reset to their initial settings whenever the power is turned on. The data listed below are backed up - i.e. retained in memory - as long as an AC adaptor is connected or a set of batteries is installed.
User Style data.. page 96 User Pad data.. page 92 Registration Memory data.. page 54 Registration Memory Bank Number.. page 56 Registration Memory/One Touch Setting status. page 55 Freeze on/off... page 55 MIDI Transmit settings.. page 114 MIDI Receive settings.. page 115 Voice Set on/off... page 120 Voice L (Voice Change, Mixer).. page 74 Fingering mode.. page 38 Split Point.. page 120 Sustain on/off... page 30 Upper Octave setting.. page 119 Pitch Bend Range.. page 122 Scale Tuning.. page 119 Transpose... page 30 Footswitch Function, Polarity.. page 121 Touch on/off, Sensitivity.. page 120 Multi Pad setting... page 43 Master Tuning.. page 119 Metronome on/off.. page 118
Even though these settings are retained in memory, you should save them and all your important data to floppy disk for permanent, safe storage. To save all of the data types listed above to floppy disk, use the Save operation (page 60) and select All as the file type. All data listed above will be lost if the power is interrupted in other words, if the power is turned off, the AC adaptor is disconnected and the batteries are removed. When this happens, the next time you turn on the PSR-550, a Clear Backup message appears in the display, the Data Initialization operation (below) is automatically executed, and the PSR-550 is set to the Style mode (page 25).

s Data Initialization

All data can be initialized and restored to the factory preset condition by turning on the power while holding the highest (rightmost) white key on the keyboard. Now Initializing will appear briefly on the display.
All registration and User Style/Pad memory data, plus the other settings listed above, will be erased and/or changed when the data initialization procedure is carried out. Carrying out the data initialization procedure will usually restore normal operation if the PSR-550 freezes or begins to act erratically for any reason.

PSR550 Multi Track Recording Tutorial
The PSR550 is equipped with a 16 Track real-time sequencer. The sequencer data is stored directly to an IBM formatted 720KB (2DD) floppy disk, with a capacity of 65,000 notes, or a 1.44MB (HD) floppy disk, with a capacity of 130,000 notes. The recordings are saved on the floppy disk in Standard MIDI File Format 0. There are various techniques that utilize the Multi Track Recording features of the PSR540. The following are some of the main techniques: I) Recording a 'Backing Track' using an Auto Accompaniment Style: This technique involves selecting one or more of the Auto Accompaniment Tracks and recording those Tracks while playing a chord progression that controls the key of the Auto Accompaniment. The final recording is an arrangement that can, for example, be used as a backing accompaniment to a solo part played on a keyboard, guitar or saxophone. The final recording can also serve as a base for adding individual parts at a later time. This is a practical technique for a beginner since it involves playing chords with the left hand and controlling Auto Accompaniment section changes as needed. Right hand playing is NOT necessary, although, the right hand can be used to control Auto Accompaniment section changes. Recording One Track at a Time: This technique involves recording one Track at a time until the Song is complete. It is practical for the user that wants to record multiple ''takes'' of a single part, a single part in various sections, or multiple parts one after the other.
Recording Melody and Auto Accompaniment Parts Simultaneously: This technique involves recording while the user plays a keyboard part with the right hand and Auto Accompaniment chords with the left hand simultaneously.
NOTE: Yamaha Style Disks (Auto Accompaniments) and XG MIDI files (Backup Tracks) are available for purchase online at www.yamahamusicsoft.com. To order by phone, call Music Dispatch at (800) 6372852.
