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 49 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.
