Reversing the Operation of Knobs, Wheels, or Faders
Most MIDI parameters assignable to knobs, wheels, or faders can be configured so that the control's operation is
reversed. Once a control is assigned to a MIDI parameter, by default the Data 2 parameter defines the minimum
value (for example, 0) while the Data 3 parameter defines the maximum value to be transmitted (for example, 127).
Reversing the operation of knobs, wheels, or faders is achieved by entering a higher value for the Data 2 parameter
(usually minimum) and a lower value for the Data 3 parameter (usually maximum). This is useful when a single fader
needs to be configured to work as a drawbar when controlling with an organ-based virtual instrument, or if a knob
needs to be configured in reverse when controlling a particular parameter. This requires two values to be specified
(values given are examples):
Key
Data 2 (example)
Data 3 (example)
The following example configures a knob, wheel, or fader to reverse its operation:
1. Press the Edit button.
2. Press the Select button or Control Select (Ctrl Sel) key.
3. Select a knob, wheel, or fader as described earlier in this guide.
4. Press the Data 2 key.
5. Enter 127 using the number keys. This configures the control to reach its maximum value when it is all the way
down.
6. Press the Data 3 key.
7. Enter 0 using the number keys. This configures the control to reach its minimum value when it is all the way up.
8. Press the Enter Key.
The Knob, Wheel, or Fader now operates reversed. What was originally the maximum position is now the minimum
position, and vice versa.
