PiTCh aDJUSTMENTS
Figure 32
Using  the PITCH  kNOB  (11): Be  sure 
the  pitch  function  has  been  activated  as 
described above. To use the piTch knoB 
(11)  turn  the  knob  either  clockwise  or 
counter-clockwise. Clockwise will increase 
the  pitch  and  counter-clockwise  will  de-
crease the pitch. 
1. PITCH kNOB (11):
This  function  will  increase  or  decrease  the 
tracks playback speed or "PITCH." The max-
imum  pitch  percentage  manipulation  in  this 
function is +/-16%. The piTch knoB (11) is 
used  to  decrease  or  increase  the  playback 
pitch. If the knob is turned counter-clockwise 
the  pitch  will  decrease,  if  the  knob  is  turned 
clockwise  the  pitch  will  increase.  The piTch 
knoB  (11) adjustment  can  be  changed  to 
range  from  +/-4%,  +/-8%,  or  +/-16%  (See 
changing  "PITCH  PERCENTAGE  RANGE" 
on the next page). The piTch knoB (11) will 
only  effect  normal  playback  and  loops  when 
the piTch  knoB (11) is active.

Figure 31
Activating  the PITCH  kNOB  (11): To 
activate  the piTch  knoB  (11) you  must 
turn  on  the  pitch  adjustment  function.  To 
activate  the piTch knoB  (11) press  the 
piTch  BUTTon  (10).  The pitch  indicator 
will  glow  in  the  LCD,  when  the  function 
is  activated.  If  the  pitch  function  is  not 
activated  the piTch  knoB  (11) will  not 
function.
PITCH ADjUSTMENTS:
The  different  pitch  adjustments  allow  a  track's  or  a  loop's  playback  speed  to  be  manipulated.  This 
speed manipulations is commonly used to beat match between two or more music sources. The play-
back speed may be increased or decreased by a factor of +/-16. The next section details the different 
pitch manipulation schemes.

2. PITCH BENDING: 
Unlike the piTch knoB (11) adjustment this function will momentarily increase or decrease a tracks 
speed  during  playback.  To  operate  the  PITCH  BEND  use  the  (-)  &  (+)  piTch  BEnD  BUTTonS  (12). 
The  maximum  pitch  bend  percentage  allowed  by piTch BUTTonS  (12)  is  +/-16%.  The  pitch  bend 
function will work in conjunction with the piTch knoB (11) pitch setting. For example, if the piTch 
knoB (11) is set to a 4% pitch gain the pitch bending process will begin at 4% and will continue to 
the maximum of +/-16%.
Holding  down  on  the (-) piTch   BE nD  BUT-
Ton (12) will provide a slow down in the play-
back pitch.
Figure 33
Using  the P ITCH   PERCENTAGE 
SELECTOR  (13): You  may  choose  a  pitch 
operating range at any time. To change the 
operating  range  be  sure  the  pitch  function 
is  turned  on,  see  figure  31.  The  pitch  per-
centage  can  be  changed  between  +/-4%, 
+/-8%, and +/-16%. 4% will allow the least 
amount  of  pitch  manipulation  and  16%  will 
allow  the  most  amount  of  pitch  manipula-
tion.  To  adjust  the  different  values,  press 
the piTch  pERcEnTAgE  BUTTon  (13) to 
change  the  percentage, until  your  desired 
percentage is reached. 
Figure 34
Holding  down  on  the (+)  piTch  BEnD 
BUTTon (12) will provide a speed bump in 
the playback pitch.
Figure 35
3. PITCH  BEND BUTTONS (12):
The (+) piTch BEnD  BUTTon (12) will increase track playback speed and the (-) piTch BEnD  BUT-
Ton (12) will decrease track playback speed. The extent to which the speed changes is proportion-
ate to the amount of time the button is pressed. For example, if the (+) piTch BEnD  BUTTon (12) is 
held  down  continuously  as  in  Figure  35,  the  speed  will  increases  and  will  continue  to  increase  until 
it reaches the percentage the piTch pERcEnTAgE BUTTon (13) is set to. When you release the (+) 
piTch  BEnD BUTTon (12) the speed will automatically return to it’s previous set speed.

aDD iN g   MUS iC  TO  yOU r  MED ia  DEV iCE
When adding music to your SD Card, USB Stick or Exteran Hard Drive the files must be in Mp3 
format. Make a folder for each artist, this will make it easier for you to find your desir ed songs. The 
file format is Mp3 only. 
Loading music into your SD Card, USB Stick, or External Hard Drive:
1. Insert your desired device into your computer. If there is no SD Card slot available, use an SD    
   Card reader and insert the reader into the USB connection on your computer.
2. The device will appear as "Removable Drive" when you access "My Compu\
ter".
3. Go to Windows Explorer or a similar program and simply "drag and drop" your music onto the    
    memory device (Removable Drive). Music will be recorded onto your memory device in the same     
 
    quality originally recored onto your computer. Note: Remember it is better if you make a folder     
 
    for each artist, and then drop that folder onto your memory device.
4. Once you are finished loading music, eject the memory device, and load it into the Media Opera-
tor.
