INTRODUCTION
Introduction
Main features
Wide range of sounds. Thirty different and expressive high-quality sounds, including a Stereo Concert Grand Piano. You can use the Layer function to simultaneously play two sounds.
Effects. The SP-250 provides built-in digital effects that can simulate the natural ambience of a concert hall (Reverb) and add richness to the sound (Chorus).
Damper pedal simulation. The Damper pedal on the SP-250 corresponds to the Damper or Forte pedal of an acoustic piano. On an acoustic piano, when you press this pedal, the pads (dampers) that stop the vibrations of the strings are lifted.
Metronome. The built-in metronome allows you to select the time signature, tempo, and volume, and even use 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. In addition to the Equal temperament, the SP-250 allows you to select two alternative classical temperaments (Kirnberger and Werckmeister) for historically accurate performance of classical music. When selecting an acoustic piano sound, the typical Stretched Tuning 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 fine tune adjustments.
MIDI capabilities. The SP-250 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-250 as a 16-part multitimbral tone generator.

Powerful integrated amplification. SP-250 includes a powerful, 11 Watt amplier, with two 10cm speakers in Bass Reflex box.
Two sets of heaphones. You can connect two stereo headphones, to play with your teacher or another musician.

Before you begin
Connecting to an external amplification system
Use the OUTPUT connectors, if you like to connect your SP-250 to a high-quality mixer, stereo hi-fi, or a couple of active monitors. When using a stereo hi-fi, connect the OUTPUTs to the AUX or TAPE inputs (never use the PHONO inputs). For mono amplification, connect only the L/MONO output.

Headphones
Using the headphones
For playing or practicing during night hours, or when you don’t want to be heard by others in the same room, connect one or two pairs of high-quality headphones (32Ω impedance suggested) to the appropriate PHONES connectors. These connectors are standard 1/4” phone jacks. If your headphones have a mini-jack adapter, grasp the adapter when plugging in or out the headphones.
Warning: When using headphones, protect your hearing by avoiding extended listening at high volumes.

Chapter 2 |
Turning the instrument on
Insert the DC plug of the supplied AC adapter into the DC inlet of the SP-250, then connect the AC plug to a wall socket. You can use the dedicated hook to fix the power cable to the piano’s back panel, as shown in the following illustration:
After having connected the power cable, press the POWER switch. When the instrument is turned on, the LEDs on the control panel will light up. To turn the instrument off, press the POWER switch again.
Note: When the instrument is turned off, all parameters are reset.
Turning the internal speakers on or off
Whether you prefer listening to the internal speakers or to an external amplification system, you can turn the internal speakers on or off. Insert a jack (or connect a headphone set) to one of the PHONES connectors to turn the speakers off.
Adjusting the volume
Move the MASTER VOLUME slider towards the right to increase the volume; towards the left to decrease the volume. The maximum is “10”; the minimum (silence) is “0”. This control adjusts the output level of the headphones, the internal speakers and of the OUTPUTs.
Note: It is always better to start with a low volume and then increase gradually.
Listening to the Demo
The SP-250 contains 30 pre-recorded demo songs. Listen to them to experience the rich sound and expressive potential of this instrument.
Listen to all songs at once. You can listen to all demo songs with a single command.

Chapter 3 |
Note: When selecting the Layer mode, the total number of voices that can play at the same time is reduced, depending on the total number of oscillators used by the selected sounds.
Note: You can’t select two sounds included under the same button.
1Press one of the sound selection buttons in order to select the first sound. The LED on the button you pressed will light. Use the BANK button to select a sound in one of the other banks.
2Press another sound selection button to select the second sound. The LED on the button you pressed will light. Use the BANK button to select a sound in one of the other banks.
3Press both buttons at the same time to select the sounds. Both LEDs will light.
Note: Steps 1 and 2 are not required, if the right banks are already selected.
Returning to the Single mode. To return to the Single mode, just press a single sound selection button.
Adjusting the volume of sounds in Layer mode. To adjust the balance between the sounds in Layer mode, hold down the button of the sound whose level you wish to decrease, and repeatedly press the button of the sound whose level you wish to raise.
Note: This setting will be memorized even after turning the Layer mode off, but will be lost when turning the instrument off. To save these settings, save them using the Data Dump function (see “MIDI Data Dump” on page 31).
Choosing the reverb and the chorus
The SP-250 has two effects: reverb and chorus. The reverb simulates the sound reverberation in a room, while the chorus simulates a modulating effect that makes the sounds richer. The effect settings will be remembered even when selecting a different sound.
Note: Effect settings made in Single mode are memorized even when selecting the Layer mode, but no change made in Layer mode will be preserved.
When the instrument is turned on, the effect settings are reset to the factory settings. To save the Single mode settings, save them using the Data Dump function (see “MIDI Data Dump” on page 31).

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.
For example if you transpose upward by one semitone, playing the notes shown at the lower left will produce the pitches shown at the right.
Note: When the instrument is turned on, the transposing is reset.
1Hold the TRANSPOSE/FUNCTION button, and press the key on keyboard that corresponds to the transpose you wish to carry out (see table). The TRANSPOSE/ FUNTION LED will remain lit up, to indicate that the transpose function is active.

Fine tuning
In order to adapt the SP-250 pitch to that of another instrument, you can adjust the pitch in steps of 0.5 Hz over a range of A4 = 427.5 ~ 452.5 Hz. The standard tuning is A4 = 440 Hz.
Note: The pitch will go back to standard level (A4 = 440 Hz) when the instrument is turned off, then on again.

Selecting a temperament
There are numerous classical compositions that were composed using temperaments that differ from the “equal temperament” commonly used today.In order to reproduce the original sound of such compositions, the SP-250 provides Kirnberger and Werckmeister classical temperaments, in addition to the equal temperament, allowing you to select from a total of three temperaments.
To select one of the available temperaments, hold down the TOUCH button, then press the button corresponding to the desired temperament. To return to the equal tuning hold down the TOUCH button, then press the sound selection button whose LED is lit.

To check the currently selected temperament, hold down the TOUCH button, and look at which of the above LEDs is turned on.
Note: When the power is turned on, the equal temperament will be automatically selected.
About stretched tuning. In order to produce the most natural resonance, PIANO 1 and PIANO 2 sounds use a “stretched tuning” that makes the notes of the lower range slightly flatter than equal temperament, and the upper range slightly sharper. This is how an acoustic piano is normally tuned by professional tuners.

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-250 to control other instruments, use other instruments to control the SP-250, and use a sequencer to create complex musical pieces.
When you use the SP-250 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
Always connect the MIDI OUT connector of the instrument to the MIDI IN connector of another instrument. Never connect two connectors of the same instrument to each other.
Connect the MIDI OUT connector of the transmitting (master) device to the MIDI IN connector of the receiving (slave) device.

Standard MIDI settings
When turning the instrument on, the MIDI parameters of the SP-250 are programmed as follows:
Parameter |
Setting |

|
Omni |
OFF |
|
|
(*) On channel 10, only metronome notes are received (D#5, E5).
Selecting the transmission channel
The standard MIDI has 16 separate channels available for transmission and reception of data. SP-250 always receives on all 16 channels, and transmits on a single channel. To transmit data from the SP-250, you need to choose which of the 16 channels you wish to transmit data on.

Note: When the power is turned on, channel 1 will automatically be selected.
Note: By default, channel 10 will automatically be assigned to the metronome sound (notes D#5-E5).
Note: In Layer mode, the second sound transmits on the following channel. For example, if you select channel 7, the first sound will transmit on channel 7, while the second sound will transmit on channel 8. If you select channel 16, the first sound will transmit on channel 16, while the second sound will transmit on channel 1 (cycling back to the first channel).
Using the SP-250 as a multitimbral tone generator
When SP-250 is controlled from an external MIDI device, it can work as a 16-part multitimbral tone generator.You can select a different sound on each of the 16 MIDI channels.
1Use a MIDI cable to connect the SP-250's MIDI IN to the MIDI OUT of a sequencer etc.
2Transmit MIDI data from the connected sequencer (or other device). See “Program Change” on page 28 for instructions on how to select a sound using the MIDI Program Change message. Program Change reception must be activated on the SP-250 (it is by default).
MIDI |
27 |
Read the other devices user’s manual for details on sending Program Change messages.
Local On/Off
Local is the parameter that allows you to establish whether the keyboard has to play the internal sounds and transmit MIDI data at the same time (Local On), or whether it just has to transmit MIDI data and not play the internal sound (Local Off).
Local Off should be chosen when you wish to use the SP-250 as a mute keyboard, to play another instrument. It should be chosen also when SP-250 is connected to a sequencer via its MIDI IN and MIDI OUT connectors. This will avoid the notes to be played twice, by the keyboard and by the sequencer, producing an annoying “echo” effect.
Normally, you will choose Local On (automatically selected when turning the SP250 on), so that playing the keyboard will produce sound.
Hold down the TRANSPOSE/FUNCTION button, and press the PIANO 1 sound selection button. The Local setting will alternate to On/Off each time you press this button.

Note: When the power is turned on, the Local will be automatically set to On.
Program Change
The sound of the SP-250 can be selected via MIDI, by sending a Program Change message on the channel where you wish to assign the sound. The table enlists the Program Change numbers (numbering from 0-29; if the transmitting device uses numbers from 1-30, you will need to increment the number by one).
Transmitting Program Change messages. You can send a MIDI Program Change message to a MIDI device connected to the SP-250 MIDI OUT, to change its sound. When selecting one of the internal sounds of the SP-250 by using the sound selection buttons, a MIDI Program Change number will be transmitted, as shown in the table below.
Receiving Program Change messages. When a Program Change message is received from an external device, the corresponding internal sound will be selected
