7.  REPEAT  BUTTON  - When  the  REPEAT  function  is  active  only  the  tracks  within  the  folder  that  is 
playing will repeat. When the REPEAT function is deactivated all tracks within the memory device will 
play.
8. IN, OUT, & RELOOP BUTTONS - 
IN  BUTTON  - “CUE  ON  THE  FLY”  - This  function  allows  you  to  set  a  CUE  POINT  (see  CUE  POINT 
page 15) without music interruption (“on the fly”). This button also sets the starting point of a seam-
less loop (see SEAMLESS LOOP on page 16).
OUT BUTTON - This button is used to set the ending point of a loop. A loop is started by pressing 
the in BUTTon, pressing the OUT BUTTON set the loop ending point. The loop will continue to play 
until the oUT BUTTon is pressed once again.
RELOOP  BUTTON - If  a  SEAMLESS  LOOP  has  been  made  (see  setting  a  SEAMLESS  LOOP  on 
page  16),  but  the  player  is  not  actively  in  SEAMLESS  LOOP  mode  (a  loop  is  not  playing),  pressing 
the RELOOP  BUTTON will  instantly  reactivate  the  SEAMLESS  LOOP  mode.  To  exit  loop,  press  the 
oUT BUTTon. LOOP and RELOOP will appear in the lcD DiSplA y (4) when the RELOOP function 
is available.
9.  TEMPO  LOCk  FUNCTION  -  This  button  activates  and  deactivates  the  TEMPO  LOCK  function. 
This  function  allows  you  to  use  the piTch knoB  (11)  to  speed  up  or  slow  down  playback  speed 
without altering the tonal pitch of the track. When this function is not engaged the original tonal pitch 
of the track will be altered giving you the "chipmunk" effect when a track is played at a high rate of 
speed, or the "James Earl Jones" effect when a track is slowed to much.
10. PITCH ON/OFF BUTTON - This button is used to turn the piTch ADjUSTmEnT knoB (11) on 
and  off.  The  pitch  percentage  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  manipulation.  To  adjust 
to the different values please see page 22. 
11. PITCH  kNOB - 
This  knob  is  used  to  adjust  the  playback  pitch  percentage.  The  knob  is  a  set  adjustment  and  will 
remain  set  until  the  pitch  knob  is  moved  or  the  pitch  function  has  been  turned  off.  This  adjustment 
can be made with or without a digital source loaded. The pitch adjustment will remain even if the digi-
tal source has been removed and will reflect on any other digital source loaded into the player. That is 
to say, if you set a +2% pitch on one digital source, remove that source and load another, that source 
too will have a +2% pitch. The amount of pitch being applied will be displayed in the lcD (4).
12. PITCH BEND BUTTONS -
(-)  PITCH  BEND BUTTON -  The (-)  pitch  bend  function  creates  a  momentary  “Slow  Down”  in  the
