FastForward(Rotate clockwise) all your jog wheels one by one and Mixpad will detect the jog wheel events and its speed. Jog wheels will be used to control FastForward and Rewind in Mixpad. If you accidently touch other Controllers(sliders or keys) on your hardware, you can use Clear All to clear all events and rotate all your jog wheels again.

When you rotate the jog wheel, your hardware will generate a MIDI event which contains the rotating speed. Generally, the speed is between 65 to 127 if you rotate clockwise and 0 to 63 if counter-clockwise. For example, 65 means rotating clockwise at the lowest speed and 0 means rotating counter-clockwise at the highest speed. Inside the Jog Wheel group the Start input means the lowest speed value and End input means the highest speed value. Please refer to your hardware manual for those values.
