Korg 250 Transpose and Fine Tuning Guide for SP-250 Keyboard Users

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 Trans- pose 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.

Key	Effect
F#6 — B6	6	— 1 semitones below
C7	Standard pitch
C#7 — F7	1	— 5 semitones higher

2To get back to standard pitch, hold the TRANSPOSE/FUNCTION button and press the C7 key. The TRANSPOSE/FUNCTION LED will turn off.

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.
