Octave/Wheels 
 
1.  PITCH:  This wheel creates expressive changes in 
performances by raising and lowering pitch.  
Rolling the Pitch Bend wheel upward will raise an instrument’s 
pitch whereas rolling it downward will lower the pitch.  
The upper and lower pitch bend limit is determined by settings 
on your hardware or software synthesizer, not by the Pitch 
Bend wheel on the  Oxygen 25 keyboard itself. Typically, this 
can be either a half note or an octave up/down.  
This wheel is spring mounted and will return to the center 
detent position when released.  
2.  MOD (Modulation): This wheel is used to add expression to 
performances by changing the intensity of certain effects.  
By default, most synthesizers assign this wheel to control 
vibrato (change in intonation) or tremolo (change in volume) 
although it is usually possible to reassign the function of this 
wheel through the instrument’s control panel.  
Rolling the Modulation Wheel upward will increase the modulation effect, while rolling downward 
will reduce the effect.  
The Modulation Wheel is an assignable controller capable of sending a variety of MIDI messages 
other than Modulation data.  
3.  OCTAVE - / +: The Octave buttons are used to shift the keyboard’s octave range up or down in 
one octave increments, extending the octave range of the pads or keys. 
TRANSPOSE:  Hold SHIFT  and press either of these buttons to transpose the keyboard up or 
down.
