Octaves and Transposition
By using the Key Octave – / + buttons, the keyboard can access the full range of 127 available
MIDI notes (10 octaves). Additionally, you can transpose the keyboard up to 12 semitones (1
octave) in either direction.
To change the octave of the keyboard, use the Key Octave – / + buttons to lower or raise the
octave, respectively. The display will temporarily show OCT and the current octave shift.
Code 25’s keyboard can be shifted 4 octaves down or 5 octaves up.
Code 49’s keyboard can be shifted 3 octaves down or 4 octaves up.
Code 61’s keyboard can be shifted 3 octaves down or 3 octaves up.
To change the transposition of the keyboard, press and hold Transpose , and then use the
Key Octave – / + buttons to lower or raise the octave, respectively. The display will temporarily
show TRN and the current transposition ( -12 to 12 ).
Important: The keyboard’s overall octave and transposition are independent from zone
octaves and transposition; all of these affect the note a key sends out. For example, if a zone’s
octave shift is set to +1, and the keyboard’s octave shift is set to +1, the notes played by the
zone’s keys will be 2 octaves higher than normal. Similarly, if a zone’s octave shift is set to +1,
and the entire keyboard’s transposition is set to -2 (semitones), the notes played by the zone’s
keys will be 10 semitones higher than normal.
