addItIOnaL Setup

This  section  covers  general  preferences  and 
adjustments  you  can  make  to  improve  the 
performance  of  Scratch  Live.  From  the  main 
screen, click on setup to get to this area.

pLayBacK

tRacK end WaRnInG

Enable  track  end  warning  to  flash  the  Virtual 
Deck as you approach the end of the track. The 
label will start flashing 20 seconds from the end 
of  the  record.  The  track  end  warning  does  not 
apply to any tracks under 1 minute long.

pLayBacK KeyS uSe ShIFt

This  is  checked  by  default.  Unchecking  this 
option  will  enable  all  of  these  keys  without 
pressing  shift  or  having  caps  lock  on.  This 
applies to all cue points (1...0) and cue controls 
(QWERTY  etc). 

See  “KeyBOaRd  ShORtcutS” 

On paGe 25.

LOcK pLayInG decK

Every DJ’s nightmare used to be lifting the needle 
off  the  wrong  turntable  in  the  middle  of  a  set. 
This setting helps to avoid the digital equivalent; 

loading  a  new  track  to  the  wrong  deck.  When 
this option is checked, you can only load a track 
if the target deck is stopped.

SORt cueS chROnOLOGIcaLLy

The five cue points can be placed in any order, 
and  can  be  dragged  up  and  down  if  you  wish 
to  reorder  them.  If  you  prefer  to  lock  them  to 
chronological order, turn this option on.

enaBLe hOt cueS

When  hot  cues  are  enabled,  you  can  set  cue 
points  simply  by  pressing  the  number  keys  1 
through  0  (no  ctrl  modifier  required).  Note  that 
you can only add cues this way if the cue point 
slots are empty. 

See “cue pOIntS” On paGe 16.

uSe autO GaIn

Auto gain enables you to set a uniform volume 
level for the tracks in your library. When a track is 
in auto gain mode, the track gain knob appears 
depressed.
  To  enable  auto  gain,  check  the  “use  auto 
gain” box under the playback tab. Provided you 
have analyzed your files, your tracks will now be 
loaded with the auto gain applied.

 

Next  to  the  “use  auto  gain”  check  box  is  a 

drop  down  menu,  in  which  you  set  the  target 
gain volume level.
  To find the optimum setting, load a track with 
an average volume level onto one of the Virtual 
Decks. Now play the track, and take note of the 
volume and LED lights inside the software.
  The idea is for the track volume to be sitting 
just  under  the  clipping  point  (indicated  by  the 
LED  meter  red-lining).  If  the  track  is  too  quiet, 
unload it, then go to the playback setup screen 
and boost the auto gain dB value more.
  Once you’ve made this adjustment, load the 
same  track  onto  the  Virtual  Deck  again.  You’ll 
notice  that  the  volume  knob  has  automatically 
adjusted itself.
  Keep making adjustments on the same track 
until it’s just below the clipping point. Once this 
is  set  you  won’t  need  to  adjust  the  target  gain 
level ever again.
  Because the track you used had an average 
volume  level,  most  of  the  other  tracks  in  your 

library should be around the same volume. You 
may  still  need  to  make  minor  adjustments  to 
some  individual  tracks,  but  once  that’s  done 
these will stay saved in the ID3 tag of the file.

tIp:  Slightly  too  quiet  is  always  better  than 
too loud. If your Led meter is in the red, it is 
likely that it is clipping. not only does clipping 
not  sound  very  nice,  it  can  damage  your 
equipment.

nOte:  your  overviews  need  to  be  built  by 
version 1.7.2 or later for auto gain to work.

hI-FI ReSampLeR

This significantly reduces digital distortion at very 
slow or very fast record speeds, increasing the 
CPU  load  slightly.  This  option  is  off  by  default, 
the old resampler is used when switched off.

pLay FROm StaRt

If  this  setting  is  not  enabled,  freshly  loaded 
tracks will continue to play from the point the last 
track was at. This option is on by default.

InStant dOuBLeS

This  allows  you  to  quickly  match  the  playhead 
position of two tracks. With this option set, when 
you  load  a  track  on  one  Virtual  Deck  that  is 
already loaded on the other Virtual Deck (it must 
be the same file), the playhead will jump to the 
position of the track that was loaded first, with 
the  keylock  state  and  looping  settings  copied. 
This  setting  overrides  the  play  from  start  and 
play from first cue point options.

pLay FROm FIRSt cue pOInt

Enable this option to start all tracks from the first 
cue  point.  This  setting  overrides  the  play  from 
start option.

BRaKInG

This  controls  how  fast  the  deck  stops  when 
play  is  stopped.  Counter-clockwise,  the  stop 
is  immediate.  Clockwise  rotation  increases  the 
stop  from  a  finger  grab  all  the  way  to  a  slow 
turntable power-down.
