KORG SP-250
Owner's Manual

Transpose
In some cases, a song may be written in a dif�cult 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.

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.
