10. PITCH bEND:
This  function  will  momentarily  increase  or  decrease  a  tracks  playback  speed.  There  are  two  ways  to  operate 
this  function  with  the  (-)  &  (+)  PITCH BUTTONS  (14)  or  with  the JOG  wHEEL  (1).  The  maximum  pitch  bend 
percentage  allowed  is  +/-  16%.  The  pitch  bend  function  will  work  in  conjunction  with  the PITCH SLIDER  (3) 
pitch setting. 
PITCH bEND bUTTONS (14):
The (+)  PITCH  BEND  BUTTON (14) will  provide  a  speed  bump  and  the (-)  PITCH  BEND BUTTON  (14)  will 
provide  a  slow  down.  The  maximum  range  of  the  PITCH  BEND  BUTTONS  is  16%.  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 (14) is held down continuously, the disc speed will increases and will continue to increase until 
reaches a maximum of 16% speed gain.  when you release the (+) PITCH BEND BUTTON (14) the disc speed 
will automatically return to it’s previous speed.
Holding  down  or  tapping  on  the 
(-)  PITCH  BEND  BUTTON (14) will 
provide  a  slow  down  in  the  play-
back pitch.
