Introduction

Main features

Thirty high-quality sounds

The SP-280 provides 30 built-in expressive high-quality sounds, including a stereo concert grand piano. You can use Layer mode to simultaneously play two sounds at once, or you can use Partner mode, which allows two people to play the same range, one on each half of the keyboard.

Effects

The SP-280 provides 3 built-in digital effects. These effects can adjust the brightness of the tone (Brilliance), simulate the natural ambience of a concert hall (Reverb) and add richness to the sound (Chorus).

Pedal effects

You can obtain the same damper effect as that of an acous- tic piano using the damper pedal that is included with the unit. You can also add the damper resonance to the classic piano and the grand piano tone (bank 1 and 2 of PIANO1). Furthermore, the damper pedal can function as a half damper pedal so that you can change the condition that the damper is applied by the depth to which the pedal is pressed.

Use optional pedal unit (sold separately) for soft and sostenuto effects in addition to the damper effect.

Metronome

The built-in metronome allows you to select the time sig- nature, tempo, and volume, and you can even choose a bell sound as the accent.

Touch control

You can choose from three different settings to adjust how the sound will respond to your keyboard playing dynamics.

Temperaments

For authentic performance of a wide range of music, the SP-280 allows you to select from nine temperaments, including the equal temperament, pure temperaments (major and minor), classical temperaments (Kirnberger and Werckmeister) as well as temperaments used with Middle Eastern and Indian folk music. When an acoustic piano sound is selected, the stretched tuning used on pianos is automatically selected.

Adjustable pitch

The Transpose function lets you change the pitch of the piano, and the Pitch Control function allows you to make finely tuned adjustments.

Two headphone jacks

Two headphone jacks (one each on the front and back of the SP-280) are provided, allowing two people to listen simultaneously.

LINE IN/LINE OUT jacks

When connecting a sound system or other electronic musical instrument to the LINE IN jack, sound from the connected device will be heard through the speakers of the SP-280. In addition, powered monitors or a recording system can be connected by using the LINE OUT jacks.

MIDI capabilities

The SP-280 supports the MIDI protocol, the standard that allows music data to be transferred between musical instruments and computers. MIDI allows two or more devices to control or be controlled by each other, and also allows you to use the SP-280 as a 16-part multitimbral tone generator.

Preparation and demo performances

Before you begin playing

About the included stand

If the stand is to be used, see the “Installing the stand” section on page 16 before connecting the AC adapter and attaching the music stand.

Connecting the Power

Connect the supplied AC adapter to the power cord. Insert the DC plug end into the DC19V jack on the rear panel of the unit. Next, plug the power cord into an AC outlet.

Pass the AC adapter cord through the cord hook so that the plug won’t be re- moved from the jack accidentally. When you unhook the cord, don’t pull the cord with force.
Be sure to use the AC adapter that came with your unit. Using other AC adapters may cause the unit to malfunction.
Be sure to plug the unit into an AC outlet of the appropriate voltage.

Using the headphones

Use stereo headphones with a stereo mini plug.
Since there is one headphone jack on the back (Fig. 1) and one on the front (Fig. 2), two people can listen simultaneously.
When the headphone plug is inserted into the headphone jack on the front or back of the SP-280, no sound will be produced from the speakers. Use headphones at night or when you don’t want disturb others.
Power Cord

If your headphones feature a standard-to-mini adapter plug, be sure to hold the adapter plug when you connect or disconnect the headphones.

To protect your hearing, do not listen to loud, high-volume sounds for a long period of time through headphones.

Using the music stand
Insert the pins on the included music stand into the music stand holes in the rear panel. (Fig. 2).
Headphones
Do not press down on the music stand with force, otherwise it may fall off the SP-280.

Turning the instrument on
Press the power button to turn on the SP-280. (Fig. 3)
When the instrument is turned on, the button LEDs on the control panel will light up. To turn the instrument off, press the power button again.

When the instrument is turned off, all functions and parameters, except the auto power off function, return to their factory default settings.

Auto power off function
When 30 minutes have passed without user input or an demo performance, the instrument will be automatically turned off. To disable this function, turn off the auto power off function (see page 12).

Adjust the volume

Rotate the VOLUME knob that’s located next to the power switch toward “MAX” to raise the volume level.
Rotate it left toward “MIN” to lower the level. (Fig. 3)
The VOLUME knob controls the output level of the built-in speakers, the headphones jacks and the LINE OUT jacks.
It is always better to start with a low volume and then increase gradually.

Souter Louder

Using the LINE IN/LINE OUT jacks
Use the LINE IN jack to listen to the sound from another musical instrument or sound system through the speakers of the SP-280. Connect this jack to the output jack of the other musical instrument or sound system.

Use an audio cable with a stereo mini plug inserted into the SP-280 and a plug on the other end appropriate for the connected device.

Use the LINE OUT jacks, if you want to connect your SP- 280 to a mixer, stereo hi-fi, or a couple of active monitors. When using a stereo hi-fi, connect the LINE OUTs to the AUX or LINE inputs. For mono amplification, connect only the L/MONO jack.

 You must only connect devices with the power turned off. Careless operation may damage the SP-280 or the device where it’s connected, or malfunctions may be caused.

  Connection cables are sold separately. You will need to obtain the appropriate commercially-available cables for your equipment.

Listening to a demo song

The SP-280 contains a total of 30 demo performances (10 demo songs using 10 high-quality sounds and 20 familiar piano songs using the piano sounds).
 During playback of a sound demo song, you can play using the keyboard; however, the sound cannot be changed by using the sound buttons.
During playback of a sound demo song, the settings for effects (reverb and chorus) cannot be changed.

Other functions

Touch settings

The keyboard sensitivity, or touch, can be programmed. The “Light” setting produces a louder sound than usual when you play softly on the keyboard; and the “Heavy” setting produces a softer sound than usual, until you play harder.

To change the setting, hold down the TOUCH button and press the UP or DOWN button beside the display.

Display Touch sensitivity
1 Light. Loud notes can be produced even by playing lightly.
2 Normal. Normal piano touch.
3 Heavy. Loud notes can be produced only by playing very hard.

The diagram below shows the relationship between how hard you play the keyboard and how loud or soft the notes will sound.

When the instrument is turned on, the touch setting is reset to Normal.
The settings are applied to all sounds.

Transpose

In some cases, a song may be written in a difficult key (e.g., many black keys), or you may wish to shift the pitch to match another instrument or vocalist. In such cases, you can transpose (shift the pitch) so that you can use an easier fingering, or use the same familiar fingering to play at a different pitch. This is called the Transpose function.
Transposing Icon

When the instrument is turned on, the transposing is reset.

While holding down the TRANSPOSE button, press the keyboard key (F 6–F7) for the desired transposition.
If a keyboard key other than C7 is pressed, the TRANS- POSE LED lights up to indicate that the keyboard is trans- posed.

The pitch of the entire keyboard is transposed according to the pitch of the pressed keyboard key in relation to C7. To return to the original pitches, hold down the TRANS- POSE button and press the C7 key. The TRANSPOSE LED turns off, and transposition is canceled.

Selecting a temperament

You can select from nine temperaments, including the equal temperament, pure temperaments (major and mi- nor), classical temperaments (Kirnberger and Werckmeis- ter) as well as temperaments used with Middle Eastern and Indian folk music.

Display Temperament
00 Equal temperament (default setting): Spacing all semitones at equal

pitch intervals, this temperament is the most widely used.
01| Pure temperament [major]: Major chords in the key (C) are perfectly tuned.
02| Pure temperament [minor]: Minor chords in the key (C) are perfectly tuned.
03| Arabic: This scale includes the quarter-tone in- tervals used in Arabic music.
04| Pythagorean: This ancient Greek scale is espe- cially effective for playing melodies. It consists of perfect fifths; however, other intervals – the major third in particular – is out of tune.
05| Werckmeister: The Werckmeister III scale was created in the later Baroque period to allow relatively free transposition.
06| Kirnberger: The Kirnberger III scale is used mainly for tuning harpsichords.
07| Slendro scale: This is an Indonesian gamelan scale with five notes per octave.
08| Pelog scale: This is an Indonesian gamelan scale with seven notes per octave.

**MIDI

**

What is MIDI?

MIDI, is the abbreviation of Musical Instrument Digital Interface. It is an international standard that was created to connect and transfer data between electronic musical instruments, computers and other devices.

What can you do with MIDI?
Thanks to MIDI, you can use the SP-280 to control other instruments, use other instruments to control the SP-280, and use a sequencer to create complex musical pieces. When you use the SP-280 keyboard or pedal, or select a sound, the notes, pedal activation and change in sound are transmitted to another instrument, or are recorded by a sequencer.

Connections
Commercially available MIDI cables are used to transfer MIDI data. Connect these cables from the MIDI connectors of the SP-280 to the MIDI connectors of the external MIDI device that you want to exchange data with. There are two types of MIDI connector.

MIDI IN connector
This connector receives MIDI messages.
The MIDI IN connector lets you play the SP-280’s sounds from an external MIDI device (e.g., MIDI keyboard or sequencer). Use a MIDI cable to connect the SP-280’s MIDI IN connector to your external MIDI device’s MIDI OUT connector.

MIDI OUT connector
This connector transmits MIDI messages.
The MIDI OUT connector lets you control an external MIDI device using the MIDI messages transmitted from the SP-280. Use a MIDI cable to connect the SP-280’s MIDI OUT connector to your external MIDI device’s MIDI IN connector.

MIDI function mode
When the SP-280 is turned on, the MIDI parameters are set to transmission channel 1, all reception channels (1–16), Local On and Omni Off.
These settings can be changed from the MIDI function mode.

Setting procedure for parameters in the MIDI function mode

  1. Hold down the FUNCTION

The PIANO 1 LED lights up, and the MIDI channel set- ting (C01) appears in the display. The FUNCTION but- ton is blinking. The FUNCTION LED will blink.

  1. Press the sound button corresponding to the desired
    The current setting appears in the display.

  2. Specify the desired

  3. After specifying the desired settings, press the FUNCTION button to return to the mode for playing. The FUNCTION LED turns off.
    Button

When the SP-280 is turned off, all parameters return to their default settings.

Changing the MIDI channels

Data can be transmitted and received on MIDI channels 1 through 16 (C01–C16).
When the SP-280 is turned on, transmission channel 1 (C01) is automatically selected.

  • After entering the MIDI function mode, the LED for the PIANO1 sound button lights
    When the MIDI function mode is entered, the MIDI channel setting normally appears.
    To specify the MIDI channel setting after changing other settings in the MIDI function mode, press the PIANO1 button.

In the Layer or Partner modes, selecting the transmission channel specifies the channel for layer 1 or the left side of the keyboard. The transmission channel for layer 2 or the right side of the keyboard will automatically be set to the following channel. For example, if MIDI channel 7 is selected for the sound of layer 1 or the left side of the key- board, MIDI channel 8 will automatically be specified for the sound of layer 2 or the right side of the keyboard. If MIDI channel 16 is selected for the sound of layer 1 or the left side of the keyboard, channel 1 will be specified for the sound of layer 2 or the right side of the keyboard.

Local On/Off

With the Local On setting, playing the SP-280’s keyboard produces the sounds of the performance as well as trans- mits MIDI data. With the Local Off setting, playing the SP-280’s keyboard does not produce the sounds of the performance; MIDI data is only transmitted. Normally this parameter is set to Local On (default setting: on).

The Local Off setting should be selected when using the SP-280 as a master keyboard, for example, to play sounds from a connected MIDI device (a keyboard, sound module, etc.). The SP-280 will not produce sound, but the perfor- mance will be played by the connected MIDI device.

Select the Local Off setting (oFF) when using the SP-280 as a sound module, for example, when the SP-280 is con- nected to a sequencer with its Echo Back setting (function that sends back data that the sequencer received) selected in order to prevent echoing of returned data.

  • Enter the MIDI function mode, and then press the PIANO2 button.
    The LED for the PIANO2 sound button lights up, and the Local On/Off setting (on) appears in the display.

Enabling/disabling program change transmis sion/reception filtering

The programs on a connected MIDI device can be changed by sending a MIDI change number from the SP-280. In addition, the programs on the SP-280 can be changed by receiving a MIDI change number from a connected MIDI device.
For program change numbers and their corresponding sounds, refer to “Table of sounds and corresponding pro- gram change numbers” below.
To transmit/receive program change messages, disable this function (oFF: default setting). To not transmit/receive the messages, enable this function (on).

  • Enter the MIDI function mode, and then press the PIANO1 button.
    The LED for the E.PIANO1 sound button lights up, and the setting (oFF) appears in the display.

Transmitting program changes

When a sound is selected using the sound buttons and BANK button on the SP-280, the corresponding MIDI pro- gram change number is transmitted.

Receiving program changes

When the SP-280 receives a MIDI program change number, the sound is changed to the corresponding one.

 If an incompatible program change number is re- ceived, the SP-280 sound is not changed.

Enabling/disabling control change transmission/ reception filtering

Messages, such as operation of the SP-280’s damper pedal, can be transmitted to a connected external MIDI device to control it, and these messages can be received from the ex- ternal MIDI device to control the SP-280.

To transmit/receive control change messages, disable this function (oFF: default setting). To not transmit/receive the messages, enable this function (on).

  • Enter the MIDI function mode, and then press the PIANO2 button.
    The LED for the E.PIANO2 sound button lights up, and the setting (oFF) appears in the display.

Using the SP-280 as a multitimbral sound module
The SP-280 can operate as a 16-part multitimbral sound module when an external MIDI device is used to control its internal sound generator.

  1. Connect a MIDI cable to the SP-280’s MIDI IN con- nector and to the MIDI OUT connector of a sequencer or other MIDI

  2. Transmit MIDI data from the connected sequencer or other MIDI
    For details on transmitting data from the connected sequencer or other MIDI device, refer to its user’s man- ual.

  3. When the SP-280 receives the program change mes- sage along with the performance data, it will play with the sound corresponding to that program num-

If the SP-280 is not to be used as a multi-timbral sound module, disable this function (oFF).

  • Enter the MIDI function mode, and then press the HARPSI/CLAV button.
    The LED for the HARPSI/CLAV sound button lights up, and the setting (on: default setting) appears in the display.

Troubleshooting

If during use any of the following problems should occur, carefully examine the instrument to see if you can find out what the problem is, and try resolving it by following the suggestions below. If the instrument will still not function properly refer to your dealer.

The instrument will not turn on

  • Check that the AC adapter is correctly connected to the piano and the outlet.

No sound

  • Make sure that the volume is not set on MIN. If it is, bring it up to an adequate level.
  • Make sure that the MIDI Local function is not set on If it is, set it to ON (or turn the instrument off and then on again).
  • Make sure there is not a jack plugged into one of the Headphones jacks. This would turn the internal speak- ers if so, unplug the jack.

Notes are interrupted

  • You have exceeded the maximum see “About maximum polyphony.”

The pitch or tone of the piano sounds wrong in some key regions

  • The SP-280’s piano sounds replicate the sound of an actual piano as faithfully as possible. This means that in some regions of the keyboard, you may feel that the overtones seem stronger, or that the tone or pitch seems wrong. This is not a malfunction.

The connected MIDI device does not respond to trans- mitted MIDI data

  • Make sure that all MIDI cables are correctly
    Make sure that the SP-280 is receiving MIDI data on the same channel as the MIDI device.

About maximum polyphony

If the number of notes being played simultaneously ex- ceeds the maximum polyphony, some notes will be lost since the SP-280 is equipped with a mechanism that stops the first note being played to give priority to notes played with keys pressed later. Some SP-280 sounds, although they may be a single sound, are generated by two or more oscillators (one note of a sound- generating circuit). Sounds using just one oscillator, such as those in banks 1 and 2 of VIBES/GUITAR, have a maximum polyphony of 120 notes. Sounds using two oscillators, such as those in banks 1 and 2 of PIANO2 and in banks 1 and 3 of E.PIANO2, have a maximum polyphony of 60 notes.

120 ÷ Number of sound oscillators = Maximum polyphony

Keep the maximum polyphony in mind and carefully choose sounds when using Layer mode to play two sounds simultaneously or when using the damper pedal.

Installing the stand

Warning

  • The stand must be installed by at least two

Installation precautions
Be sure to observe the following precautions in order to safely and correctly perform the installation.

  • Make sure that the correct parts are in the correct ori- entation and position, and perform the installation in the order of the steps provided.

Other precautions
Observe the following precautions after the stand has been installed.

  • Loosened screws
    Since the screws may become loose as time passes af- ter installation, we recommend periodically checking for loose screws. In addition, if you feel that the stand shakes excessively, it may be due to screws becoming loose. In that case, re-tighten them.

  • When transporting the instrument
    Transporting the instrument with the stand installed may result in unforeseen damage. Remove the stand from the SP-280, and then transport them separately. After they have been transported, re-install the stand as described in “Installing the stand”.

  • Removal
    Remove the stand by reversing the installation proce- dure. After removal, store the screws and other parts so they will not be lost.

Installation procedure
Make sure that all of the following parts are available.
In addition, check if enough of the bolts on the front legs extend out (14 mm or more), and then install the legs after adjusting the bolt lengths.

 If the bolts are not long enough (less than 14 mm), turn the adjusters until they reach an appropriate length.

In order to prevent damage to the keyboard or knobs of the SP-280, prepare some magazines, fabric or moderately stiff cushions (see below).

  1. Turn over the SP-280.
    In order to avoid placing the SP-280 directly on the floor, place magazines or fabric at each end as shown below, and then place the instrument upside- down on top of them.
    When turning over the SP-280, be careful that it does not become unbalanced and dropped.
    Installation Procedure

  2. Install the front legs (one each on the left and right). Screw the front legs (without braces attached) clock- wise (direction of arrow) into the screw holes on the keyboard side of the stand base.
     Make sure that the adjusters are not loose.

  3. Install the rear legs (one each on the left and right). Screw the rear legs (with braces attached) clockwise (direction of arrow) into the screw holes on the back side of the stand base.
    Installation Procedure

  4. Loosen knob bolts B for the braces attached to the rear legs.

  5. After adjusting the braces so that the screw hole on their ends contact the installation positions on the SP-280, secure the brace ends with knob bolts A.

  6. Tighten knob bolts B for the braces attached to the rear legs.
    Installation Procedure

  7. Check the surrounding area, and then turn over the SP-280 without hitting anything.

Adjusting front leg clearances to floor

Follow the procedure below to finely adjust the clearances between the front legs and the floor within 3 mm.

  1. Turn either the left or right front leg counterclock- wise (direction of arrow 1) a little at a time to adjust the clearance between the front leg and the floor.
  2. Hold the adjusted leg so it does not turn, and then turn the adjuster at the top of the leg clockwise (di- rection of arrow 2) until it is firmly secured.

Installation Procedure

Check after installation

  • Are any parts left over?
    If any parts are left over, carefully review the assembly procedure to see where those parts should have been used.

  • Make sure that all screws are
