Keyboard 
 
The keyboard is velocity-sensitive and can access the full range of 127 available MIDI notes across 
10 octaves. 
Pressing SHIFT and one of the labeled keys allows you to quickly edit Smart Chord, Smart Scale, 
Arpeggiator, Channel and Velocity functionality. 
 
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.

To change the transposition of the keyboard, press and hold Shift, and then use the Key Octave 
–/+ buttons to lower or raise the keybed by one one, respectively. The display will temporarily show 
the current transposition (-12 to 12).
