3.STARTING PLAYBACK - Figure 11
Insert  an  audio  CD  as  describe  on  page  10  (LOADING/EJECTING  DISCS).  
Pressing  the PLAY/PAUSE  BUTTON  (15)  with  an  audio  CD  inserted  will 
immediately start playback. The PLAY (41) indicator will glow as soon as playback 
begins. The  point  at  which  playback  starts  (cue  point)  will  automatically  be  stored 
in  the  memory  as  the  cue  point. The  unit  will  return  to  this  cue  point  (the  point 
at  which  playback  started)  when  the CUE  BUTTON  (13) or  the  BOP  BUTTON 
(20) is pressed.
4. AUTO CUE
When  a  disc  is  loaded,  the  unit  will  automatically  set  a  cue  point  to  the  first 
audio  source,  usually  the  beginning  of  track  1.  If  a  new  track  is  selected  before 
the PLAY  BUTTON  (15)  is  pressed,  a  new CUE  POINT will  be  set  to  reflect 
the new starting point.
5.STOPPING PLAYBACK - Figures 11 & 12
Stopping  playback  will  not  stop  the  drive  mechanism,  but  merely  pause  or  cue  the 
track,  this  functions  allows  the  unit  to  begin  play  instantly.  The  drive  mechanism 
will  only  stop  if  a  disc  is  ejected  or  the  unit  has  gone  in  to  sleep  mode. There  are 
two ways to stop (pause) playback:
1)Press the PLAY/PAUSE BUTTON (15) during playback. This will pause playback 
    at the exact same point the  PLAY/PAUSE BUTTON (15)  was pressed. 
2) Press the  CUE BUTTON (13)  during playback. This will pause playback and 
     return the track to the last set cue point.  
6. PAUSING  - Figure 11
This  function  pauses  playback  at  the  exact  same  point  the  PLAY/PAUSE  BUTTON 
(15)  was  pressed.  Pressing  the  PLAY/PAUSE  BUTTON  (15)   will  switch  between 
play  and  pause  modes. When  the  unit  is  in  pause  mode  the  PAUSE  INDICATOR 
(46)   in  the  LCD  DISPLAY  (1)   will  glow.  The  green  PLAY/PAUSE  BUTTON 
(15)  LED will also begin to flash repeatedly.
7. FRAME SEARCH 
This  feature  allows  you  to  scroll  through  a  track  frame  by  frame,  allowing  you  to  
find  and  set  a  starting  cue,  sample,  or  loop  point. To  use  the  scroll  function  you  
must  first  be  in  Pause  Mode  (see  section  5)  or  Cue  Mode  (see  section  7). Once  
you  are  in  Pause  or  Cue  mode,  turn  the  JOG  WHEEL  (14) to  scroll  through 
the  track  (Figure  13). Turning  the  wheel  in  a  clockwise  direction  will  advance  the  
frame  search  and  turning  the  wheel  in  a  counter-clockwise  direction  rewinds  the  
frame  search.  When  you  use  the  JOG  WHEEL  (14)  the  monitor  (headphone 
level)  function  allows  you  to  here  what  you  are  scrolling  through. Once  you  reach  
your  desired  starting  point  you  can  set  a  cue  (starting)  point  by  pressing  the  
PLAY/PAUSE BUTTON (15)  as in Figure 11. Pressing the  CUE BUTTON (10) as 
in Figure 12 will now return you to the point you just set.

This  function  gives  you  a  fast  search  through  a  disk  or  track.  Turn  the 
SEARCH  WHEEL  (5)  in  clockwise  direction  for  fast  forward  or  turn  the 
wheel  counterclockwise  for  fast  reverse.  You  can  scan  in  four  different 
forward  and  four  different  reverse  speeds  depending  on  how  much  you 
rotate the wheel.
9.  SETTING and STORING a CUE POINT:
Setting A Cue Point:
A  cue  point  is  the  exact  point  playback  will  begin  when  the PLAY/PAUSE  (15)  is  pressed. You  may  set  your 
cue points anywhere on a disc or in a track. You may set up to four independent cue points per disk. Three cue 
points are stored in the FLASH BUTTONS 1-3 (6) and one in the IN BUTTON (12). Figures 15 and 16 will detail 
the procedures for setting your custom cue points. There are two (2) ways to set a CUE point:
American DJ® AUDIO • Pro Scratch 1™  •  INSTRUCTION MANUAL • PAGE 12
 BASIC OPERATIONS (CONT.)
1)You  may  press  the IN  BUTTON  (12)  on  the  fly  (while  the  disc  is  playing).  This 
    will set a CUE Point without music interruption. Pressing the  CUE BUTTON (13) will 
     now return you to the same point that you pressed the  IN BUTTON (12). You may 
     now store this CUE Point in any of the  FLASH BUTTONS 1-3 (6). Pressing the
     CUE BUTTON (13), BOP BUTTON (20)  or the IN BUTTON (12)  will now return 
     you to this exact point. 
2) You may also use the JOG WHEEL (14) to set a cue point. While a disc is in 
     PAUSE or CUE mode, use the  JOG WHEEL (14) to scroll through a track to find 
     your desired starting point. Once you have found your desired position press the 
     PLAY  BUTTON  (15)   to  set  your  cue  point.  Pressing  the  CUE  BUTTON  (13) 
     or the  IN BUTTON (12)  will now return you to this exact point.

							Storing A Cue Point:
Once  you  have  set  your  CUE  Point  by  one  of  the  two  means  listed  on  page  12,  you  may  store  your  cue  point 
in one of the FLASH BUTTONS (6). Either a CUE POINT or a SAMPLE (See creating a sample loop on page 
14)  can  be  stored  into  a FLASH  BUTTONS  (6),  not  both. Once  you  store  this  cue  point  in  memory  you  may 
recall  it  at  any  time  and  you  may  even  recall  if  the  disc  has  been  remove  or  power  had  been  disconnected. 
You  may  store  a  maximum  of  three  cue  points  per  a  disc  and  maximum  of  384  cue  points  can  saved 
in  unit's  memory.  The MEMORY  BUCKET  (53)  on  the LCD  DISPLAY  (1)  will  approximate  the  available 
memory. To Store a cue point:
1)Press the MEMORY CUE BUTTON (12), as in Figure 17. The red Memory Cue LED will glow indicating 
    memory  is  ready  to  be  stored. You  may  now  press  any  one  of  the  three  FLASH  BUTTONS  (6) to  store 
     your cue point into memory (Figure 18). After pressing one of the  FLASH BUTTONS (6), the corresponding 
     Flash Button LED will flash briefly. The LED will remain lit indicating either a sample or cue point is stored 
     in memory. The red Memory Cue LED will now shut off.
2) Repeat  the  above  steps  to  store  up  to  three  Cue  Points.  Once  all  your  three  cue  points  have  been 
     stored you may access them at any time. The cue points will instantly start without any music interruption.
     Please note in order to access these cue point, the disc used to create the cue points must be in the drive.
10. CREATING AND PLAYING A SEAMLESS LOOP 
A  seamless  loop  is  a  sound  loop  that  plays  continuously  without  sound  interruption. You  can  use  this  loop  to  
create  dramatic  effect  in  your  mixing. This  loop  has  no  time  limit  and  you  could  actually  loop  the  entire  length  
of disc. You create a seamless loop between two continuous points of a disc.

11.  EDITING A LOOP:
Please  note  you  can  only  edit  the  ending  point  of  the  loop. You  may  make  your  loop  shorter  or  longer. Before 
you  can  edit  your  seamless  loop  you  obviously  must  first  have  created  a  seamless  loop  to  edit. If  you  haven’t 
created  a  SEAMLESS  LOOP,  follow  the  instructions  in  step  10.  If  a  SEAMLESS  LOOP  has  already  been 
created,  press  the RELOOP  BUTTON  (19)  to  activate  your  SEAMLESS  LOOP  (Figure  23)  if  it  is  not  already 
playing. To edit your seamless loop’s ending point:
1)Press the OUT BUTTON (18) to return to normal play from the loops cue point. (Figure 20). This will 
    disengage the SEAMLESS LOOP mode and allows you to edit the loops ending point.
2) Press the  OUT BUTTON (18)  again when you reach your new ending point (Figure 21).
     - FOR A SHORTER LOOP:  Press the OUT BUTTON (18 ) at sooner point in the track (Figure 21).
     - FOR LONGER LOOP:  Press the OUT BUTTON (14)  at later point in the track (Figure 21).  
 BASIC OPERATIONS (CONT.)
3)Press the OUT BUTTON (18) to set the ending point for your SEAMLESS 
    LOOP (Figure 13). The  IN BUTTON (12) and OUT BUTTON (18)  LEDs will 
     begin to flash indicating SEAMLESS LOOP mode has been activated.
LOOP INDICATORS - During a seamless loop, the  LOOP (44) and RELOOP 
(45) INDICATORS  will light in the LCD DISPLAY (1)  indication a loop is active.
    
EXITING  A  LOOP  -  To  exit  a  SEAMLESS  LOOP,  press  the 
OUT  BUTTON  (18) .  The IN  BUTTON  (12)  and OUT  BUTTON 
(18)  LEDs  will  remain  on,  but  will  stop  flashing. Music  playback 
will  resume  normal  play  (Figure  13). The  IN  BUTTON  (12) and 
OUT  BUTTON  (18)   LEDs  will  remain  on  to  remind  you  that  a 
loop is stored in memory.
REPLAY  LOOP  -  The  RELOOP  (19)   function  allows  you  to  return  to  your 
stored  loop  at  any  time. The  IN  BUTTON  (12) and OUT  BUTTON  (18)    LEDs 
will  indicate  a  loop  is  stored  in  memory,  and  may  be  played  at  any  time.  To  
replay  the  loop,  press  the  RELOOP  BUTTON  (19). The IN  BUTTON  (12)   and 
OUT BUTTON (18)  LEDs will again begin to flash indicating SEAMLESS LOOP 
mode  has  been  activated  (Figure  14)  and  your  stored  loop  will  immediately  
begin to play.

							12. Using the Built In Sampler:
Your  Pro  Scratch  1  comes  with  a  built  in  sampler. You  may  store  up  to  three  samples  on  the  three FLASH 
BUTTON |b). Your sample can be a maximum of 6.5 seconds in length. A sample can be recalled while a CD is 
playing|f WHILE THE #$ DRIVE IS IN 0!53% -/$%\f or even without the CD in the player. You may play your sample 
at  anytime  without  music  interruption. If  you  play  your  sample  when  the  unit  is  already  in  playback  mode  you 
sample will over lap the current music source. You can also play your sample once or in a continuous loop. As 
with cue  points  y ou  m ay store  a  maxi mum  of  128*3  sample  per  in  a  d riv es  memo ry . The  MEMO RY B UCKET

							Changing the Sample Parameters:
Changing  the  sample  parameters  allows  you  to  change  the  sample's  volume  and  pitch.  The 
parameters values for both the pitch and volume settings range from 00:00 to 20:00, 00:00 being the 
lowest value. A higher value will increase the pitch percentage or volume. It's important to understand 
that  the  pitch  value  is  basic  a  speed  adjustment  and  has  nothing  to  do  tonal  quality. The  values  can 
be  either  a  momentary  change  or  set  adjustment.  The  sample  values  are  changed  in  three  easy 
steps, while in sample playback mode:  
 BASIC OPERATIONS (CONT.)
American DJ® AUDIO • Pro Scratch 1™ INSTRUCTION MANUAL • PAGE 16
Figure 28
Figure 29
Figure 30
Changing the Sample Parameters - Step 1:
While  a  sample  is  playing  tap  the PARAMETERS  BUTTON  (28). One  tap 
will display SP 10 00 in the LCD DISPLAY (1). If you tap the PARAMETERS 
BUTTON  (28)  again, SV  10  00 will  read  out  in  the LCD  DISPLAY  (1). SP 
will  signify  the  pitch  percentage  and SV will  signify  the  sample  volume. 
10  00  is  your  default  setting  -  Normal  playback.  Any  adjustments  will  be 
based on this default setting.
Changing the Sample Parameters - Step 3:
Use  the  JOG  WHEEL  (14)  to  change  your  selected  parameters. Turning 
the  wheel  in  a  clockwise  rotation  will  increase  your  parameters  -  this  will 
wither  increase  the  volume  or  increase  the  pitch.  Turning  the  wheel  in 
counter-clockwise  direction  will  decrease  the  parameters  value  -  either 
decreasing  the  volume  or  decreasing  the  pitch.  If  you  turn  the  HOLD 
BUTTON  (2)  in  the  previous  step,  you  would  turn  the  hold  function  off 
to save your settings.
Changing the Sample Parameters - Step 2:
Hold  Function  - This  mode  will  allow  you  to  save  and  lock  your  parameter 
adjustments,  if  the  hold  function  is  not  activated  all  your  parameter 
adjustments will be momentary. Once you are in the parameters mode you 
can begin to make your adjustments.  American DJ¤

							13. Reverse Play:
Reverse  play  allows  you  to  play  a  track,  loop,  or  sample  backwards. This  function  is  activated  by  pressing  the 
REV/PLAY BUTTON (26) as in figure 31. This function will react differently to different playback modes:
 - Reverse track/disc play. In this mode the unit will playback in reverse until 
   the reverse function is turned off. If the reverse function is not turned off 
   the unit will continue to play the remainder of the disc in reverse mode until it
    reach the begging of the disc. When the unit comes to the beginning it will 
   automatically cue to the first track. If the unit is paused in this mode it will 
   continue to play in reverse when playback begins again.
 - Reverse loop play. In this mode the loop will play in reverse once and turn off.
     If the reverse function is turned off at this point, the loop will continue in regular 
   play. If the OUT BUTTON (18) is pressed during reverse loop playback mode, 
   playback will continue in reverse until the reverse function 
 - Reverse sample play. In this mode the unit will play the sample in reverse 
   continuously, until the reverse function is turned off. If another sample is 
      selected that sample will also play in reverse mode. If a sample is activated 
      over a track both the track and the sample will play in reverse until the 
   reverse function is turned off.
14.  Creating a BOP Effect:
The Bop Effect is a stutter effect that is similar to turntable scratching. You can use this effect to create tricks in 
your mixing. Creating a BOP effect is a simple process:
 
 4) When you discontinue the BOP effect normal playback 
     will resume from the point you initial started your BOP.

							15.FLASH START BUTTONS (6): 
These  button  are  used  to  store  your  samples  and  cue  points.  Only  a  sample  or  a  cue  point  can  be  stored 
in  to  each  of  these  three  banks. When  a  sample  is  store  in  to  these  banks  you  may  use  the  sample  starting 
point    as  a  cue  point.  The FLASH  BUTTONS  instantly  recall  and  play  any  of  your  stored  samples  or  cue 
points  without  interrupting  music  playback.  When  in  sample  mode  (see  "Using  the  Built-In  Sampler"  on 
page  15)  during  playback,  pressing  any  of  the FLASH  BUTTON  that  has  a  sample  stored  in  it  and  your 
sample  will  immediately  begin  to  play  without  interruption  of  music.  If  the  unit  is  sample  mode  and  the 
drive  is  in  pause,  pressing  any  of  the FLASH  BUTTON  that  has  a  sample  stored  in  it  will  immediately 
begin to play the sample.
16.CHANGING THE TIME DISPLAY (49 & 50)/TIME BAR (51):
DURING  NORMAL  PLAYBACK,  pressing  the  TIME  BUTTON  (25),  will  change  the 
time  display  information  (49,  50,  56,  &  57)  in  the  LCD  see  figure  35. The  following  is 
a break down of the time settings and their definitions:    
1)ELAPSED (57) - This describes the time in the LCD (49, 50, &52) as the current 
TRACKS Elapse running time.
2)REMAIN  (56) - This describes the time in the LCD (49, 50, &52) as the current 
TRACKS remaining running time.  
3)TOTAL REMAIN (56) - This describes the time in the LCD (49, 50, &52) as 
    the disc total remaining running time.   
TIME BAR INDICATOR  - Details the time defined in the  TIME METER (49 & 50) as a 
visual bar icon. As with the  TIME METER (49 & 50) this bar is also dependent on the 
selected  time  function  [TOTAL  REMAIN  (56), REMAIN  (56)  OR  ELAPSE  (57)] . This 
bar  will  begin  to  flash  when  a  track  is  ending  regardless
 of  which  time  function  you 
are in. Use the flashing bar as a visual reminder that a track is ending.
17. FLIP-FLOP™
This  feature  is  kind  of  “auto  pilot”.  When  you  are  using  two  Pro  Scratch  1™  players  and  an  American  DJ  
“Q” Deck™  mixer,  you  can  have  one  player  begin  playback  when  the  other  ends. You  can “Flip  Flop™” single  
tracks, the entire disc, or a combination of the two.

							17. PITCH BENDING:
This function will momentarily increase or decrease the tracks playback speed. There are two ways to operate 
this  function  with  the  |b
	  &  |b	  PITCH  BUTTONS  |b  &  22)  or  with  the JOG  WHEEL  |b).  The  maximum 
pitch  bend  percentage  allowed  is  +/-  100%. The  pitch  bend  function  will  work  in  conjunction  with  the PITCH 
SLIDER |b) pitch setting. The PITCH SLIDER |b) adjustment can be changed to range from +/-8%|f 
\f 
or  +/-16%  |b3EE  changing  "PITCH  SLIDER  PERCENTAGE  RANGE"  on  page  20).  For  example|f  if  the PITCH 
SLIDER  |b)  is  set  to  a  2%  pitch  gain  the  pitch  bending  process  will  begin  at  2%  and  will  continue  to 
the maximum of -/+100%.
PITCH BEND BUTTONS |b  	:
The |b	  PITCH  BEND  BUTTON |b	 will  provide  a  speed  bump  and  the |b
	  PITCH  BEND  BUTTON  |b)  will 
provide a slow down. The extent to which the speed changes is proportionate to the amount of time the button 
is  pressed. For  example|f  if  the  |b	  PITCH  BEND  BUTTON  |b)  is  held  down  continuously|f  the  disc  speed  will 
increases and will continue to increase until reaches a maximum of 100% speed gain. When you release the |b	 
PITCH BEND BUTTON |b) the disc speed will automatically return to it’s previous speed.

Using  the  Pitch  Slider  (17): To  use  the  pitch  slider  (17)  slide  the  slider 
up  and  down.  Down  will  increase  the  pitch  and  up  will  decrease  the  pitch. 
When the slider is in the center position, a green LED just left of the slider will 
glow. When this slider is glowing there is zero pitch being applied to the track, 
regardless if the pitch function is on or off. 
Adjusting  the  Pitch  Slider's  Range  (17): You  may  change  the  pitch  slider's 
(17) operating range. To change the operating range be sure the pitch function 
is  turned  on,  see  figure  39. The  pitch  percentage  can  be  changed  between 
8%,  12%,  and  16%.  8%  will  allow  the  least  amount  of  pitch  manipulation 
and  16%  will  allow  the  most  amount  of  pitch  manipulation.  To  adjust  to  the 
different  values  tap  the  8%  12%  16%  button  (23). The  LED  above  the PITCH 
PERCENTAGE  BUTTON  will  indicate  which  pitch  percentage  mode  you  are 
in  by,  glowing  green  for  8%,  glowing  orange  for  12%,  or  glowing  red  for  16%. 
Note, the pitch percentage must be activated to get a LED reading.
Activating  the  Pitch  Slider  (17): To  activate  the PITCH  SLIDER  (17)  you 
must  turn  on  the  pitch  adjustment  function.  Press  the ON/OFF  BUTTON 
(24)  located  in  the  pitch  control  section.  The ON/OFF  BUTTON  (24)  LED 
will  glow  when  the  function  is  activated.  If  the  pitch  function  is  not  activated 
the PITCH  SLIDER  (17)  will  not  function,  however  the  pitch  bend  buttons 
will function normally.American DJ¤
