day) to prevent the possibility of panel disguration or damage to the internal components. 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 uids, 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 specied 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.

ISAVING USER DATA

Always save data to an external device such as the Yamaha MIDI data ler MDF3 frequently, in order to help prevent the loss of important data due to a malfunction or user operating error. Yamaha cannot be held responsible for damage caused by improper use or modications 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. * The illustrations and LCD screens as shown in this owners manual are for instructional purposes only, and may be different from the ones on your instrument.
Congratulations on your purchase of the Yamaha PSR-280 PortaTone! You now own a portable keyboard that combines advanced functions, great sound and exceptional ease-of-use in a highly compact package. Its outstanding features also make it a remarkably expressive and versatile instrument. Read this Owners Manual carefully while playing your new PSR-280 in order to take full advantage of its various features.

Main Features

The PSR-280 is a sophisticated yet easy-to-use keyboard with the following features and functions:

I Yamaha Education Suite

The PSR-280 features the new Yamaha Education Suite a set of learning tools that utilize the latest technology to make studying and practicing music more fun and fullling than ever before! The Yamaha Education Suite includes:

@7 PHONES/OUTPUT jack This is for connection to a set of stereo headphones or to an external amplier/speaker system. (See page 9.) @8 DC IN 10-12V jack This is for connection to a PA-3B AC power adaptor. (See page 8.)

Setting Up

This section contains information about setting up your PSR-280 for playing. Make sure to read this section carefully before using the instrument.

Power Requirements

Although the PSR-280 will run either from an optional AC adaptor or batteries, Yamaha recommends use of an AC adaptor whenever possible. An AC adaptor is more environmentally friendly than batteries and does not deplete resources.
Never interrupt the power supply (e.g. remove the batteries or unplug the AC adaptor) during any PSR-280 record operation! Doing so can result in a loss of data.
I Using an AC Power Adaptor
To connect your PSR-280 to a wall socket, you will need the optionally available Yamaha PA-3B Power Adaptor. Use of other AC adaptors could result in damage to the instrument, so be sure to ask for the right kind. Connect one end of the adaptor to the DC IN 10-12V jack on the rear panel of your PSR-280, and the other end to a suitable electrical outlet.
Use ONLY a Yamaha PA-3B AC Power Adaptor (or other adaptor specically 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 PSR280. Unplug the AC Power Adaptor when not using the PSR-280, or during electrical storms.

I Using Batteries

G Inserting Batteries Turn the instrument upside-down and remove the battery compartment lid. Insert six 1.5-volt size D (SUM-1, R-20 or equivalent) batteries as shown in the illustration, making sure that the positive and negative terminals are properly aligned, and replace the lid.

BATTERIES 1.5V x 6

Never mix old and new batteries or different types of batteries (e.g., alkaline and manganese). To prevent possible damage from battery leakage, remove the batteries from the instrument if it is not to be used for a long time.
G When the Batteries Run Down When the batteries run low and the battery voltage drops below a certain level, the PSR-280 may not sound or function properly. As soon as this happens, replace them with a complete set of six new batteries.

Turning On the Power

With the AC power adaptor connected or with batteries installed, simply press the power switch until it locks in the ON position. When the instrument is not in use, be sure to turn the power off. (Press the switch again so that it pops up.)

Step 3

Auto Accompaniment

Using the Auto Accompaniment
The powerful yet easy-to-use Auto Accompaniment features give you professional instrumental backing for your performances. Simply play chords with your left hand and the PSR-280 automatically produces appropriate bass, chord and rhythm backing. Use your right hand to play melodies, and youll sound like an entire band!

Step 4

Lesson

Using the Lesson Feature

Songs 001 to 100 are specially designed for use with the educational Lesson feature. Lesson makes it fun and easy to master these songs. You can practice the left- and right-hand parts of each song individually: simply press the appropriate button, [L] (left) or [R] (right). The practice steps below apply to either hand. Lesson 1 Timing.This lesson step lets you practice just the timing of the notes. Lesson 2 Waiting.In this lesson step, the PSR-280 waits for you to play the correct notes before continuing playback of the song. Lesson 3 Minus One.This lesson step plays back the song with one part muted letting you play and master the missing part yourself. Lesson 4 Both Hands.This lesson step is the same as Minus One, except in that both the left- and right-hand parts are muted letting you play and master both hands.

Stop the accompaniment.

You can do this in one of three ways: I Pressing the [START/STOP] button The rhythm/accompaniment stops playing immediately. I Using an Ending section Press the [INTRO/ENDING] button. The accompaniment stops after the Ending section is nished. I Pressing the [SYNC START] button This immediately stops the accompaniment and automatically enables Sync Start, letting you re-start the accompaniment by simply playing a chord or key in the auto accompaniment section of the keyboard.
To have the Ending section gradually slow down (ritardando) as it is playing, press the [INTRO/ ENDING] button twice quickly.

Sync Stop

This convenient feature lets you stop (or pause) the auto accompaniment by releasing your ngers from the auto accompaniment section of the keyboard. Playing the chord again restarts the auto accompaniment. This is ideal for putting dynamic breaks in your performance for example, stopping the rhythm and accompaniment briey while you play a melodic break or solo with your right hand.
Press the [SYNC STOP] button.
Setting Sync Stop to on before starting the auto accompaniment automatically sets Sync Start to on as well, letting you immediately start the accompaniment by playing the keyboard.

The tempo of style playback can be adjusted over a range of 32 - 280 bpm (beats per minute).
When accompaniment playback is stopped and a different style is selected, the tempo returns to the default setting of the new style. When switching styles during playback, the last tempo setting is maintained. (This allows you to keep the same tempo, even when changing styles.)
Restoring the Default Tempo Value

A- REPEAT

Set point B (the end point).
As the song continues playing, press the [A-B REPEAT] button once again, at the ending point to be repeated. The selected phrase repeats indenitely until stopped.
If youre repeat practicing a particularly difcult section, try slowing down the Tempo to an appropriate speed to make it easier to play and master the part. You may also want to slow down the Tempo while setting the A and B points; this makes it easier to accurately set the points. You can also set the A-B Repeat function when the song is stopped. Simply use the [ REW] and [ FF] buttons to select the desired measures, pressing the [A-B REPEAT] button for each point, then start playback. To set the A point to the beginning of a song, press the [A-B REPEAT] button before starting playback.

A-b REPEAT

Pause or stop playback as needed.
Use the [PAUSE] button or [START/STOP] button. Stopping playback does not cancel the set A/B points or the A-B Repeat function.
Turn off the A-B Repeat function.
Press the [A-B REPEAT] button.

Melody Voice Change

The PSR-280 lets you play a melody on the keyboard along with each of the songs, either with the original melody voice or one of your own selection. The convenient Melody Voice Change feature takes this one step further it lets you replace the original voice used for the melody of the song with the panel voice of your own selection. For example, if the current voice selected on the panel is piano but the songs melody is being played by a ute voice, using Melody Voice Change will change the ute melody voice to piano.

Song Lesson

The Lesson feature provides an exceptionally fun and easy-to-use way to learn how to read music and play the keyboard. There are a total of 100 Lesson songs (Songs 001 to 100), specially designed for use with the educational features. Lesson lets you practice the left- and right-hand parts of each song independently, step by step, until youve mastered them and are ready to practice with both hands together. These practices are divided into four Lesson steps, as described below. Lessons 1 - 3 apply to each hand; press the appropriate button, [L] (left) or [R] (right) to select the desired part for practice.

I Lesson 1 Timing

This lesson step lets you practice just the timing of the notes any note can be used, as long as you play in rhythm.

I Lesson 2 Waiting

In this lesson step, the PSR-280 waits for you to play the correct notes before continuing playback of the song.

I Lesson 3 Minus One

This lesson step plays back the song with one part muted, letting you play and master the missing part yourself in rhythm and at the proper tempo.

I Lesson 4 Both Hands

Lesson 4 is a Minus One practice essentially the same as Lesson 3, except that both the left- and right-hand parts are muted letting you play and master both hands at the same time.
Select one of the Lesson songs.
The Lesson songs are divided into several different categories or music genres, with 100 songs available.
Select the part you wish to work on (left or right) and the Lesson step.
If you want to work on the right-hand part, press the [R] button; to work on the left, press the [L] button. Pressing either button repeatedly cycles through the available Lesson steps in order: Lesson 1 Lesson 2 Lesson 3 Off Lesson 1, etc. The selected Lesson step is indicated in the display.

After the lead-in, the song starts automatically, and the appropriate notes appear in the display. In Lesson 1, simply play one note repeatedly in time with the music. Regarding chords and the use of the left hand, the PSR-280 actually has two different types of songs: 1) songs with normal left-hand chords, and 2) songs in which the left hand plays arpeggios or melodic gures in combination with the right. In the case of the rst type, play the chords with your left hand in the auto accompaniment section of the keyboard.
In this lesson step, the PSR-280 waits for you to play the correct notes before continuing playback of the song. This lets you practice reading the music at your own pace. The notes to be played are shown in the display, one after another, as you play them correctly.
Select one of the Lesson songs. Select Lesson 2.
Press the [L] or [R] button (repeatedly, if necessary) until Lesson 2 is indicated.

After the lead-in, the song starts automatically, and the appropriate notes appear in the display. In Lesson 2, play the correct notes at your own pace, until you can master playing them in rhythm.
This lesson step lets you practice one part of the song in rhythm at the proper tempo. The PSR-280 plays back the song accompaniment with one part muted (either the left part or the right) letting you play and master the missing part yourself. The notes you are to play are shown continuously in the display as the song plays back.
Select one of the Lesson songs. Select Lesson 3.
Press the [L] or [R] button (repeatedly, if necessary) until Lesson 3 is indicated.
Play the appropriate part with the song.
After the lead-in, the song starts automatically, and the appropriate notes appear in the display. In Lesson 3, listen carefully to the un-muted part, and play the muted part yourself.
Lesson 4 is a Minus One practice essentially the same as Lesson 3, except that both the left- and right-hand parts are muted letting you play and master both hands at the same time. Go on to this lesson step after youve mastered each hands part in the previous three lesson steps. Practice both hands in time with the rhythm along with the notation in the display.
Select one of the Lesson songs. Select Lesson 4.
Press the [L] and [R] buttons simultaneously, so that Lesson 4 is indicated.
Play both the left- and right-hand parts with the song.
After the lead-in, the song starts automatically, and the appropriate notes appear in the display. In Lesson 4, both parts (left and right) are muted, letting you play the entire song by yourself.
The Lesson feature has a built-in evaluation function that monitors your practicing of the Lesson songs, and just like a real teacher, it tells you how well you did each exercise. Four grades are assigned, depending on your performance: OK, Good, Very Good, and Excellent. When the Talking function (page 66) is on, the PSR-280 also announces your grade.

BulkRcv

The display returns to the currently selected voice.
If, for some reason, some problem occurred in the data reception, a RcvError message is shown in the display. Check all connections and settings and try the operation again.
Using Initial Setup Send with a Sequencer
The most common use for the Initial Setup Send function is in recording a song on a sequencer that is intended for playback with the PSR-280. Essentially, this takes a snapshot of the PSR-280 settings and sends that data to the sequencer. By recording this snapshot at the start of the song (before any actual performance data), you can instantly restore the necessary settings on the PSR-280. Provided there is a pause in the song, you could also do this in the middle of a song for example, completely changing the PSR-280 settings for the next section of the song.
I Sending Initial Setup Data
First, set up the sequencer for recording.
The actual procedure may differ depending on your particular equipment and software. Ideally, you should leave two or more measures of silence (no performance data) before the song begins. The Initial Setup data should then be recorded to this space in the song.
Indicates MIDI is selected
Select the Initial Setup Send operation.
Press 2 on the numeric keypad or use the [+]/[-] buttons to select operation #2, Initial Setup Send.

2 INIT SND

Press the [START/STOP] button.
Start the Initial Setup Send operation.
Start recording on the sequencer, then send the Initial Setup data.
Start recording on the sequencer in the normal way, then with as little delay as possible press the [+] button to actually start transmitting the data. An End message briey appears in the display when the operation is complete.

The Voice List includes MIDI program change numbers for each voice. Use these program change numbers when playing the PSR-280 via MIDI from an external device. Some voices may sound continuously or have a long decay after the notes have been released while the sustain pedal (footswitch) is held.

Setting Up

This section contains information about setting up your PSR-280 for playing. Make sure to read this section carefully before using the instrument.

Power Requirements

Although the PSR-280 will run either from an optional AC adaptor or batteries, Yamaha recommends use of an AC adaptor whenever possible. An AC adaptor is more environmentally friendly than batteries and does not deplete resources.
Never interrupt the power supply (e.g. remove the batteries or unplug the AC adaptor) during any PSR-280 record operation! Doing so can result in a loss of data.
s Using an AC Power Adaptor
To connect your PSR-280 to a wall socket, you will need the optionally available Yamaha PA-3B Power Adaptor. Use of other AC adaptors could result in damage to the instrument, so be sure to ask for the right kind. Connect one end of the adaptor to the DC IN 10-12V jack on the rear panel of your PSR-280, and the other end to a suitable electrical outlet.
Use ONLY a Yamaha PA-3B AC Power Adaptor (or other adaptor specically 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 PSR280. Unplug the AC Power Adaptor when not using the PSR-280, or during electrical storms.

s Using Batteries

q Inserting Batteries Turn the instrument upside-down and remove the battery compartment lid. Insert six 1.5-volt size D (SUM-1, R-20 or equivalent) batteries as shown in the illustration, making sure that the positive and negative terminals are properly aligned, and replace the lid.

BATTERIES 1.5V x 6

Never mix old and new batteries or different types of batteries (e.g., alkaline and manganese). To prevent possible damage from battery leakage, remove the batteries from the instrument if it is not to be used for a long time.
q When the Batteries Run Down When the batteries run low and the battery voltage drops below a certain level, the PSR-280 may not sound or function properly. As soon as this happens, replace them with a complete set of six new batteries.

Turning On the Power

With the AC power adaptor connected or with batteries installed, simply press the power switch until it locks in the ON position. When the instrument is not in use, be sure to turn the power off. (Press the switch again so that it pops up.)
Even when the switch is in the STANDBY position, electricity is still owing to the instrument at the minimum level. When you are not using the PSR-280 for a long time, make sure you unplug the AC power adaptor from the wall AC outlet, and/or remove the batteries from the instrument.

This feature talks to you through the speakers, announcing the Grade comments as well as the titles of the Lesson steps.

2 Medium

Indicates Touch function is on
Use the numeric keypad or [+]/[-] buttons to set the desired setting: 1, 2, or 3 (explained below).

q Settings:

1 (Soft) 2 (Medium) 3 (Hard) This results in limited touch response, and produces a relatively narrow dynamic range, no matter how lightly or strongly you play the keys. This lets you play over a normal dynamic range (soft to loud). This is designed for playing very soft passages, giving you slightly more detailed control in the soft volume range.
When Touch is turned off, a constant volume (corresponding to a velocity value of 80) is produced.
Restoring the Default Touch Sensitivity Value
The default Touch Sensitivity is 2 (Medium). To restore the default value, press both [+]/[-] buttons simultaneously (when Touch Sensitivity is selected).

Effects

The PSR-280 is equipped with a wide variety of effects that can be used to enhance the sound of the voices. The PSR-280 has three separate effect systems Reverb, DSP, and Harmony and each has many different effect types to choose from.

Reverb

The Reverb effect reproduces the natural ambient wash of sound that occurs when a instrument is played in a room or concert hall. A total of eight different Reverb types simulating various different performance environments are available.
Select the Reverb function.
Current Reverb Type name and number.
Twelve additional Reverb Types are available when controlling the PSR-280 from a MIDI device. (For details, see page 86.)

Set the Reverb Type, if desired.
Use the numeric keypad or [+]/[-] buttons to set the desired Reverb Type. (For a list of the available Reverb Types, see page 32.) To turn the Reverb effect off, select Reverb Type #9.
Each style of the PSR-280 has its own independent Reverb setting.
Restoring the Default Reverb Type
If youve changed the Reverb Type, you can instantly restore the default setting by pressing both [+]/ [-] buttons simultaneously (when Reverb is selected).

Starting with an Intro section
Each style has its own two- or four-measure Intro section. When used with the auto accompaniment, many of the Intro sections also include special chord changes and embellishments to enhance your performance.
To start with an Intro section:
1) Press the [MAIN/AUTO FILL] button to select which section (A or B) is to follow the Intro.
2) Press the [INTRO/ENDING] button.

Indicates Intro standby.

INTROA
To actually start the Intro section and accompaniment, press the [START/STOP] button.
Using Sync Start with an Intro section
You can also use the Sync Start function with the special Intro section of the selected style.
To use Sync Start with an Intro section:
Indicates selected section (MAIN A or B).
3) Press the [SYNC START] button to enable Sync Start, and start the Intro section and accompaniment by playing any key on the keyboard. (When auto accompaniment is on, play a key or chord in the auto accompaniment section of the keyboard.)
Change chords using the auto accompaniment feature.
Try playing a few successive chords with your left hand, and notice how the bass and chord accompaniment change with each chord you play. (Refer to page 42 for more information on how to use auto accompaniment.)
The [ACMP ON/OFF] button can also be used to turn off and on the bass/chord accompaniment while playing allowing you to create dynamic rhythmic breaks in your performance. You can use the Sync Stop function to create a similar, yet even more dramatic break. With Sync Stop on (page 39), you can control breaks in the rhythm and accompaniment simply by releasing your ngers from the keys. As long as you play and hold a chord, the accompaniment continues. When you release it, the accompaniment stops. You can also use this feature to create exciting rhythmic stutter effects, chord hits, and accents by playing staccato chords.
Chords played in the auto accompaniment section of the keyboard are also detected and played when the accompaniment is stopped. In effect, this gives you a split keyboard, with bass and chords in the left hand and the normally selected voice in the right.

Stop the accompaniment.

You can do this in one of three ways: s Pressing the [START/STOP] button The rhythm/accompaniment stops playing immediately. s Using an Ending section Press the [INTRO/ENDING] button. The accompaniment stops after the Ending section is nished. s Pressing the [SYNC START] button This immediately stops the accompaniment and automatically enables Sync Start, letting you re-start the accompaniment by simply playing a chord or key in the auto accompaniment section of the keyboard.
To have the Ending section gradually slow down (ritardando) as it is playing, press the [INTRO/ ENDING] button twice quickly.

Sync Stop

This convenient feature lets you stop (or pause) the auto accompaniment by releasing your ngers from the auto accompaniment section of the keyboard. Playing the chord again restarts the auto accompaniment. This is ideal for putting dynamic breaks in your performance for example, stopping the rhythm and accompaniment briey while you play a melodic break or solo with your right hand.

Chord (C) Display C C(9) C6 C6(9) CM7 CM7(9) C C(9) C6 C6(9) CM7 CM7(9)
Notes in parentheses can be omitted. Playing two same root keys in the adjacent octaves produces accompaniment based only on the root. A perfect fth (1 + 5) produces accompaniment based only on the root and fth which can be used with both major and minor chords. The chord ngerings listed are all in root position, but other inversions can be used with the following exceptions: m7, m7b5, 6, m6, sus4, aug, dim7, 7b5, 6(9), 1+2+5. Inversion of the 7sus4 and m7(11) chords are not recognized if the notes shown in parentheses are omitted. The auto accompaniment will sometimes not change when related chords are played in sequence (e.g. some minor chords followed by the minor seventh). Two-note ngerings will produce a chord based on the previously played chord.

MIDI Functions

The PSR-280 is MIDI-compatible, featuring MIDI IN and MIDI OUT terminals and providing a variety of MIDI-related controls. By using the MIDI functions you can expand your musical possibilities. This section explains what MIDI is, and what it can do, as well as how you can use MIDI on your PSR-280.

What Is MIDI?

No doubt you have heard the terms acoustic instrument and digital instrument. In the world today, these are the two main categories of instruments. Lets consider an acoustic piano and a classical guitar as representative acoustic instruments. They are easy to understand. With the piano, you strike a key, and a hammer inside hits some strings and plays a note. With the guitar, you directly pluck a string and the note sounds. But how does a digital instrument go about playing a note?
Acoustic guitar note production Digital instrument note production

Sampling Note

Tone Generator (Electronic circuit)

Playing the keyboard

Pluck a string and the body resonates the sound.
Based on playing information from the keyboard, a sampling note stored in the tone generator is played through the speakers.
As shown in the illustration above, in an electronic instrument the sampling note (previously recorded note) stored in the tone generator section (electronic circuit) is played based on information received from the keyboard. So then what is the information from the keyboard that becomes the basis for note production? For example, lets say you play a C quarter note using the grand piano sound on the PSR-280 keyboard. Unlike an acoustic instrument that puts out a resonated note, the electronic instrument puts out information from the keyboard such as with what voice, with which key, about how strong, when was it pressed, and when was it released. Then each piece of information is changed into a number value and sent to the tone generator. Using these numbers as a basis, the tone generator plays the stored sampling note. q Example of Keyboard Information

Select the MIDI operations.
Press the right Overall button, repeatedly if necessary, until MIDI is selected.
This function cannot be used in the Song playing, recording or when the accompaniment is playing.

1 BULKDUMP

Select the Bulk Dump operation.
Press 1 on the numeric keypad or use the [+]/[-] buttons to select operation #1, Bulk Dump.

Start the operation.

Press the [START/STOP] button to start the Bulk Dump operation.
The following display is shown while the data is being sent.

BulkSend

When the operation is completed, the following display appears:
When the Bulk Dump operation is completed, the PSR-280 automatically returns to the previous panel condition.

s Loading Bulk Data

Once youve saved PSR-280 data as described above, you can easily reload the data back to the PSR-280.
This operation erases any and all of your original data in the PSR-280. Make sure to save your original settings and data using the Bulk Dump operation (page 71).
Set up the connected MIDI device for sending the appropriate data.

MIDI IN MIDI OUT

Make sure that the PSR-280 is not in the middle of an operation, such as song recording or playback, Style (accompaniment) playback, saving of a Registration Memory preset, sending of Bulk Dump data, etc.
2) Insert the appropriate oppy disk (containing the desired data) into the MIDI Data Filer.
Start sending the data from the connected MIDI device.
Send the data from the connected device. (Refer to the owners manual of the device for details.) The PSR-280 automatically receives the data. The following display is shown while the data is being received.
When the PSR-280 is receiving bulk data, none of the panel controls can be used.

BulkRcv

The display returns to the currently selected voice.
If, for some reason, some problem occurred in the data reception, a RcvError message is shown in the display. Check all connections and settings and try the operation again.
Using Initial Setup Send with a Sequencer
The most common use for the Initial Setup Send function is in recording a song on a sequencer that is intended for playback with the PSR-280. Essentially, this takes a snapshot of the PSR-280 settings and sends that data to the sequencer. By recording this snapshot at the start of the song (before any actual performance data), you can instantly restore the necessary settings on the PSR-280. Provided there is a pause in the song, you could also do this in the middle of a song for example, completely changing the PSR-280 settings for the next section of the song.
s Sending Initial Setup Data

There is no sound even when the keyboard is played or when a song is being played back. Playing keys in the right hand section of the keyboard does not produce any sound. The sound of the voices or rhythms seems unusual or strange. The auto accompaniment doesnt turn on, even when pressing the [ACMP ON/OFF] button. The accompaniment or song does not play back even when pressing the [START/STOP] button. The accompaniment does not sound properly.
When playing back one of the Pianist styles (#086 - #100), the rhythm cannot be heard.
Not all of the voices seem to sound, or the sound seems to be cut off.
A strange flanging or doubling sound occurs when using the PSR-280 with a sequencer. (This may also sound like a dual layered sound of two voices, even when Dual is turned off.) The footswitch (for sustain) seems to produce the opposite effect. For example, pressing the footswitch cuts off the sound and releasing it sustains the sounds. The sound of the voice changes from note to note.
Data Backup & Initialization

s Data Backup

Except for the data listed below, all PSR-280 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 Song Data Song Volume Registration Memory Data Registration Memory Bank Number Metronome Volume Touch On/Off Tuning Grade On/Off Talking On/Off

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. CLr Backup will appear briey on the display.
All Registration Memory and User song 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-280 freezes or begins to act erratically for any reason.

CLr Backup

Voice List

s Maximum Polyphony

The PSR-280 has 32-note maximum polyphony. This means that it can play a maximum of up to 32 notes at once, regardless 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.
The Voice List includes MIDI program change numbers for each voice. Use these program change numbers when playing the PSR-280 via MIDI from an external device. Some voices may sound continuously or have a long decay after the notes have been released while the sustain pedal (footswitch) is held.
