The Virtual Deck
shows everything
about the speed and
position of a track.
As the vinyl rotates,
so does the line on
the label. The circular
progress bar around
the edge is a visual representation of the position
within the song, and can be set to ash to warn
you that the track is nearing its end. The time
and remaining time are displayed in minutes
and seconds. The pitched BPM (BPM with pitch
adjustment multiplier added) is shown on the left
of the Virtual Deck, and the turntable speed as
a percentage pitch shift is shown on the right
of the Virtual Deck. If the track has no BPM
information, pitched BPM will not be shown.
If you are playing regular vinyl, notice the
Virtual Deck behaving strangely as Scratch Live
attempts to decode the incoming signal. This
will not cause any problems, but you may nd it
distracting. You can unload the currently loaded
track using the Virtual Deck eject button.

Each Virtual Deck in
Scratch Live has a
unique input / output
source, which you
can change to suit
the layout of your DJ
setup.
To set a USB
Source in Scratch
Live, click the USB Source dropdown box above
the Virtual Deck.
E.g: If a Virtual Deck has “Channel 1” selected,
this means it is controlled by the turntable / CDJ
plugged into Input 1 on the SL 4, and the audio
from Scratch Live will be sent to Output 1. The
same applies to the other channels: 2, 3, and 4.
You may want to change your display to
4-Deck Stack Mode to assign all the Decks at
once. 

When the track is playing several waveforms are
displayed. Each shows a different aspect of the
track being played.
tempO matching diSpLay
The Tempo Matching display area provides a
helpful tool for beat matching. Scratch Live
detects the beats within the track, and places
a row of orange peaks (for the track on the left
side) above a row of blue peaks (for the track
on the right side) in the Tempo Matching display
area. When the two tracks are matched to the
same tempo, the peaks will line up. The tempo
display is aligned with the beginning of the bar,
so the peaks keep their relative position as the
track plays. This display does not show the
relative timing of the beats, only the tempos of
the tracks. The peaks will still line up when the
tracks are playing at the same tempo, but are
out of sync.

This view provides a complete overview
of the track waveform, and includes
a marker to show the current position
within the track. This view is useful for
nding transitions within the track. The
waveform is colored according to the
sound spectrum – red representing
low frequency bass sounds, green
representing mid frequency sounds and
blue representing high frequency treble
sounds.
You can jump to different positions
within the track by clicking on the Track
Overview display (disabled in ABS
Mode). Grey lines behind the overview show
the length of the track – a thin grey line every
minute, and a thick grey line every 5 minutes.
The overview will be lled when you load the
track onto a Virtual Deck. On slower computers,
you should disable   in the

This view provides a close-up
of the track, including color
coding to show the frequency
of the sound; red representing
low frequency bass, green
representing mid-frequencies
and blue representing high-
frequency treble sounds.
You can also switch to a
three-band spectrum view
by holding the ctrl key and
clicking on the waveform. Click
on the waveform to ‘scrub’ or
make ne adjustments to your
position within the track. This applies to INT
Mode only, and may be useful if you wish to set
cue points in your tracks without your turntables
or CD players connected. The Main Waveform is
zoomed around the current position in the track.
