Transpose

In some cases, a song may be written in a difcult 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 ngering, or use the same familiar ngering 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.
Hold 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.

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.
Button Both LEDs turned off HARPSI/CLAV Temperament Equal temperament. Nearly all keyboard instruments today use equal temperament. This temperament spaces all semitones at equal distances, and allows identical scales to be played in any key. Werckmeister. This is the Werckmeister III scale invented by Andreas Werckmeister, the German organist and music theoretician. This scale was created in the later Baroque period to allow relatively free transposition. Kirnberger. This is the Kirnberger III scale invented by Johann Phillip Kirnberger in the early 18th century, and is used mainly for tuning harpsichords.

VIBES/GUITAR

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 atter than equal temperament, and the upper range slightly sharper. This is how an acoustic piano is normally tuned by professional tuners.

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.

Program Change enable/disable. To transmit and receive this kind of data, you must enable Program Change messages transmission and reception. Otherwise, you can disable Program Changes data.
Hold down the TRANSPOSE/FUNCTION button, and press the PIANO 2 sound selection button. Each time you press the switch, the setting will alternate between Enabled and Disabled.
Program Change status Enable Cancel PIANO 2 LED status Lit Dark
Note: When the power is turned on, program changes will be enabled for all MIDI channels.

Control Change

When you operate the damper pedal, adjust the balance in Layer mode, or make other adjustments on the control panel, a Control Change message is sent to a connected external MIDI device. At the same time, SP-250 can receive a Control Change message from an external MIDI device connected to its MIDI IN, to control the damper pedal, volume adjustment, and other data.
Control Change enable/disable. To transmit and receive this kind of data, you
must enable Control Change messages transmission and reception. Otherwise, you can disable Control Changes data. Hold down the TRANSPOSE/FUNCTION button, and press the E.PIANO 1 sound selection button. Each time you press this button, the setting will alternate between Enabled and Disabled.

Note: When the power is turned on, Control Change messages will be enabled on all MIDI channels.

MIDI Data Dump

You can save the current sound settings (Single or Layer mode) on an external MIDI storage device, like a sequencer or a MIDI data ler. You can later reload these data into the SP-250, to restore a saved set of data. Warning: To avoid loosing data, carefully read the owner's manual of your MIDI data ler. Loading data into the memory of the SP-250 will erase all existing data. Hint: To avoid any trouble, dont forget to deactivate System Exclusive data reception on the connected device. The following table shows which data are saved with the Data Dump.
Category Single mode Layer mode Data Reverb and chorus settings (on/off status, send level) Balance between sounds, damper pedal on/off status for each sound.
Saving data to the data ler. Here is how to save the data of the SP-250.
Use a MIDI cable to connect the SP-250 MIDI OUT to the MIDI IN of the data ler. Prepare the data ler to receive MIDI data. On the SP-250, hold down the TRANSPOSE/FUNCTION button, and press the VIBES/GUITAR sound selection button. The LEDs of the TRANSPOSE/FUNCTION and VIBES/GUITAR buttons will blink, indicating that the SP-250 is ready to transmit the data dump. Press the TOUCH button. The data dump will begin, and the sound setting data will be transmitted to the data ler. During a data dump operation, the SP-250 will not produce sound, and no other function will work. When the data dump is completed, you will return to normal playing condition. You may cancel a data dump operation before the data dump begins, by pressing the TRANSPOSE/FUNCTION or VIBES/GUITAR button.

Loading data from the data ler. You can load into the SP-250 data you previously saved on a data ler.
Use a MIDI cable to connect the MIDI IN of the SP-250 to the MIDI OUT of the data ler.
On the SP-250, hold down the TRANSPOSE/FUNCTION button and press the VIBES/GUITAR sound selection button. The LEDs of the TRANSPOSE/FUNCTION and VIBES/GUITAR buttons will blink, and the SP-250 will wait to receive the data dump. Set the data ler to send the sound setting data that were previously saved from the SP-250. Please read the data ler owners manual for details on data transmission. The SP-250 will receive the data. When the data dump is nished, the SP-250 will return to the same status it was before the data dump. During a data dump operation, the SP-250 will not produce sound, and no other function will work. You may cancel a data dump operation before the data dump begins, by pressing the TRANSPOSE/FUNCTION or VIBES/GUITAR button.

Appendix

Troubleshooting
If during use any of the following problems should occur, carefully examine the instrument to see if you can nd 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 or to an Authorized Korg Service Center.

Problem The instrument will not turn on. No sound. Possible remedy Check that the AC adapter is correctly connected to the piano and the outlet. (1) Make sure that the volume is not set on 0. If it is, bring it up to an adequate level. (2) Make sure there is not a jack plugged into one of the PHONES connectors. This would turn the internal speakers off. if so, unplug the jack. (3) Make sure that the MIDI Local function is not set on OFF. If it is, set it to ON (or turn the instrument off and then on again). Page 13

Polyphony

The SP-250 contains sampled sounds, which have been recorded, analyzed and processed from the actual sounds of the original musical instruments. These sounds usually consist of one or more different samples reproduced by pressing a key. Each sample is played back by a single oscillator. Sounds using just one oscillator have a full polyphony of max. 60 voices, while sounds using two oscillators have a limited polyphony of max. 30 notes. Sounds using more oscillators have a more limited polyphony. When the number of notes exceeds the limit of the sound, some notes will be stopped, so that the new ones can be heard.

Chapter 7

Furthermore, when playing in Layer mode with more than two notes, the max. polyphony depends on how many oscillators are used in total. Using the REVERB, CHORUS further reduces the polyphony, respectively, by 10 and 3 notes. Please refer to the table on page 16 for more information about the number of oscillators used by each sound.
