1. While holding CANCEL, press OCT UP or OCT DOWN repeatedly to select the transposition value. You may transpose anywhere from 5 semitones down to 6 semitones up.
Note that transposition will work in conjunction with OCT UP and OCT DOWN. For example, if you wish to transpose the keyboard up 9 semitones:
1. Press OCT UP. The keyboard will be transposed up one octave (or 12 semitones).
2. While holding CANCEL, press OCT DOWN three times.
