4. JOG WHEEL – This wheel can be used for pitch bending, scratching and searching through the music
playing on the deck. The functionality of the wheel is determined by the two accompanying buttons –
SCRATCH and SEARCH.
While a track is playing on the deck, the jog wheel functions as a pitch bend. Pitch bending
temporarily speeds up (turn clockwise) or slows down (turn counter-clockwise) the music. This
technique is used when you are mixing two beat-matched tracks which may not be completely
synchronized. Hence, with pitch bending you can temporarily slow down or speed up the track
you are mixing so its beats "lock" with the beats of the track that is already playing.
While a track is paused, you can use the jog wheel to seek through the music to a new cue point
location. Pressing PLAY/STUTTER following this will set the cue point at this location.
In Scratch Mode, the jog wheel allows you to scratch the music in much the same way that a DJ
scratches a vinyl record. As the music is playing, you can move the jog wheel back and forth to
create a scratching effect. When you stop the wheel, normal playback will resume. To resume
with no gap in the audio, "push off" by scratching forward at approximately normal playback
speed before releasing the wheel.
In Search Mode, the jog wheel allows you to quickly scan and search through the music playing.
When Scratch Mode is enabled, turning the jog wheel will quickly fast forward and rewind.
5. SCRATCH – Use this button to engage Scratch Mode. Scratch Mode allows you to "scratch" the music
on the deck by moving the jog wheel forward and backward.
6. SEARCH – Use this button to engage Search Mode. Search Mode allows you to use the jog wheel to
quickly scan through the current track.
automatically exit Search Mode.
7. PITCH SLIDER – Each deck features a pitch slider which is used to control the speed of the music.
Moving the slider toward "-" results in a lower pitch (and slower tempo) of the music, while moving the
slider toward "+" results in a higher pitch (and faster tempo) of the music.
8. PITCH BUTTON – This button adjusts the range of control the Pitch Slider has on the overall speed of
music. Pressing the button will cycle through pitch ranges of ± 0, 6, 12, 25, and +25/-100%. Selecting
0 will deactivate the pitch slider.
Note: Different pitch ranges allow for different precision over the speed of the music. Selecting a
smaller pitch range, such as ±6%, allows you to have more precise control over the speed of the
music. Selecting a larger pitch range, such as +25/-100%, allows for more extreme speed
adjustments and can be used for interesting effects.
9. TAP – Pressing this button in time with the beat will help the Beatkeeper detect the proper tempo.
Holding the button for 1 seconds will cause the BPM counter to reset and recalculate.
10. MODE – Pressing this button will bring up deck options, such as Track Loading, Time Display and
Fader Start. You can use the PUSH SELECT knob to dial in the desired values and pressing down on
the knob will move on to the next option. Pressing MODE button again will exit the deck options dialog.
Track Loading – Manual, Automatic, Continuous, Cyclic
Time Display – Elapsed, Remaining
Fader Start – Off, Cue, Pause (please see Fader Start Connectors in "Rear Panel Overview"
section for more information on Fader Start)
