16. Reverse/Bleep Button
Reverse – changes the direction of the platter and the music until it is released. This action can be
adjusted to be instant or controlled by the platter action through the program menu options.
Bleep – temporarily reverses the music from buffer while the unit continues forward motion. When the
toggle is released the unit resumes play from the point where play would have occurred otherwise.
17. Scratch Mode Button– toggles between the way the music reacts to movement by the record.
Scratch – allows the vinyl to act just like a typical record on turntable.
Scratch + FWD - allows the vinyl to act just like a typical record on turntable but only plays forward
actions. Hold "Scratch" for 1 second to get in the FWD mode.
Scratch + CUE – moves the music to the last set Cue Point every time the wheel is grabbed for scratch.
Scratch + CUE + FWD – moves the music to the last set Cue Point every time the wheel is grabbed for
scratch. Hold "Scratch+CUE" for 1 second to get in the FWD mode.
18. Pitch Button - adjusts the amount of control the Pitch Slider has on the overall speed of music and
platter. Pressing the button will cycle through pitch ranges of 6, 12, 25, and 100%. Pressing and
holding 2 seconds will deactivate and activate pitch.
19. Pitch Slider - controls the overall speed of the music and platter. At pitch settings of -80% to -100%,
the platter will deactivate and the music will be controlled by the slider. By moving the slider toward
"+" the speed of the music speeds up. By moving toward "-" the speed slows down. At 100% pitch
range, the music can be completely stopped or played at 2 times the original speed.
To match the speeds of two units, you can either monitor the music of both units by ear, or use the
automatic BPM readout and adjust the speed to match. When the tempo of the music of the CD you wish
to match is slow compared to the tempo of the other music, move the slider to the (+) end and match
the BPM. When faster, move the pitch slider to the (-) end. By making this adjustment the speeds will
be matched, though the beats may not yet be aligned.
20. Key Lock – holds the music at the current key. If the pitch slider is moved, the speed will change, but
the key will remain the same. By putting the pitch at 100% you can actually slow the music to a
complete stop while playing the last heard tones of the music. This works very well on vocals and can be
a very cool effect. If the unit has Key Lock active after the track has been changed and before Play is
hit, the unit will lock to the 0% key. If "Key" is deactivated during Pause, the unit will reset to match the
current pitch position. If "Key" is deactivated during Play, the key will remain at the new position until
the track is changed.
To change the key of the music press and hold "Key Lock" while moving the "Track/Menu Select Knob".
The key can increase to 1 octave above normal, or up to 2 octaves above normal when the Slide effect is
used. The key can decrease up to 5 octaves below normal. The display will limit to 19 half steps above
or below the normal key.
21. Jog Wheel - is used for searching, adjusting the parameters of effects, trim, and key. When the motor is
off, this wheel is used to control pitch.
22. Search - changes the mode of the "Jog Wheel" search mode. Search will remain active while the wheel
is being moved and for 8 seconds after. Moving the wheel clockwise rapidly moves forward through the
music. Counterclockwise moves backwards through the music. Search will automatically turn off after 8
seconds of non-use.
23. The Beatkeeper™ - utilizes the latest patented Beatkeeper™ technology. The Beatkeeper™
automatically tracks beats based upon a combination of frequencies and rhythm patterns in the music.
It shows BPM in the display and outputs 4-count (a.k.a. one measure) information about the music in a
marching bar graph.
The Bar Graph: Most dance music and rock is set up in 4 beat increments called measures. Many of the
features within the unit use this information for incredible results. It's important to understand the
basics of how the Beatkeeper™ works to effectively take advantage of other advanced features in
the unit. The bottom LED is for the 1
downbeat so the unit sets the first beat to where the music begins. Occasionally this may not be
correct or you may wish to reset it. To reset the downbeat simply tap the "TAP" button at the new
downbeat location as the music is playing or while in Pause.
TAP: This button is used for resetting the downbeat and also re-calibrating the BPM. The Beatkeeper™
is considered by many to be the most accurate automatic beat counter on the market today,
however, it occasionally may have trouble determining the correct BPM. This can happen when the
music contains complex rhythms, or if it starts without a beat at all. If you know the BPM showing
in the display is incorrect, or if the beat LEDs are not flashing with the beat, you have 2 options to
reset the Beatkeeper™.
1. Press the Tap button on the downbeat and hold for a second. This will tell the unit to re-
calculate and display the next BPM it finds.
2. If holding the "TAP" button doesn't work, you can manually hit the "TAP" button on the beat
and the display will indicate the new BPM. The BPM will be based upon the average of your
last 8 taps. The Beatkeeper™ will then know which beats in the music it should be using to
determine the correct BPM and it will track them through the song.
Occasionally, the unit will be tracking the wrong beat but have the correct BPM. To reset the
downbeat, simply hit the "TAP" button once on the downbeat.
