15. PITCH BENDING
• This function momentarily increases or decreases the playback speed of a CD respectively when the
+ PITCH BEND or - PITCH BEND button is pressed. The extent to which the speed changes is
proportionate to the amount of time the button is pressed. For example, if the + PITCH BEND BUTTON
is held down continuously, the CD’s speed increases and will continue to increase until reaches a
maximum of 16% gain in speed. When you release the + PITCH BEND BUTTON the speed of the CD
will automatically return to it’s previous speed.
• The pitch can be changed from +/- 8%, +/- 12% or +/- 16% range. See changing PITCH PERCENTAGE.
• The jog wheel will temporarily bend the pitch if a track is in play mode. Rotating the wheel clockwise
will speed up your track and rotating the wheel counter-clockwise will slow the track down. The speed
that you rotate the JOG WHEEL determines the percentage (%) of the PITCH BEND.
16. TRACK PROGRAM PLAY

MATCHING THE BEATS PER MINUTE (BPM)
Matching the Beats Per Minute (BPM)
This function allows you to match the beat of two separate music sources.
• With the unit, there are two ways to adjust the playing speed and match the BPMs of the two CDs:
• Use the pitch slider to adjust the BPM statically.
• Use the PITCH BEND buttons to change the BPM temporarily.
1) Pitch Slider - To adjust the BPM by sliding the pitch slider up or down, press the PITCH button to
turn on the PITCH adjustment function before use. The BPM decreases when the pitch slider is moved
upward and increases when the pitch slider is moved downward. The adjustment range is +/- 10%.
2) Pitch Bending - The BPM increases or decreases respectively while the PITCH BEND+ or PITCH
BEND- button is pressed. The BPM increase depends on how long you hold the button. If you hold the
button for about 1/2 second, the BPM will go either to +16% for PITCH BEND+ or -16% for PITCH
BEND-. If you tap the button, the BPM will only change a little so you can change the beat slightly
without audible changes in the music. The CD will return to the tempo indicated by the Pitch slide
when you let go of the PITCH BEND + or -. Figure 15 shows an example of how to use the pitch bend
