VISUAL AIDS
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.
When the two tracks are matched to the same
tempo, the peaks will line up. Note that 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 track
tempos. The peaks still line up when the tracks
are at the same tempo, but are out of sync.
TRACk OVERVIEW DISPLAY
This view provides a complete overview
of the track waveform, including a
marker to show the current position
within the track. This view is useful for
finding transitions within the track. The
waveform is colored according to the
sound: 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 filled when you load the
track onto a Virtual Deck. On slower computers,
you should disable
Autofill overviews
in the
Setup screen – with this setting disabled, the
overview will be filled as you play the track.
SEE “PREPARING YOUR FILES” ON PAGE 14 AND
“AUTOFILL OVERVIEWS” ON PAGE 35.
MAIN WAVEFORM DISPLAY
This view provides a close-up
of the track, including color
coding to show the frequency
of the sound; red representing
low frequency bass sounds,
green representing mid-
frequency sounds 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
fine 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.
See
“CUE POINTS” ON PAGE 21 AND “SCRATCH LIVE
MODES” ON PAGE 19.
TIP: Use the + and – keys to zoom in and out.
TIP: Waveform can be either vertical or horizontal.
SEE “DISPLAY MODES” ON PAGE 18.

wave represents a kick drum, while
the purple part represents a snare
drum.

BEAT MATCHING DISPLAY
This view shows the position of beats
within the track. When beat matching,
this helps align the downbeats of the
two tracks. The markers are matched
when the two tracks are beat matched.
Example:
The following is a
demonstration of using the visual aids
to help beat match. In this example,
the track that is playing is on the Left
Deck, and the track to be mixed in is
on the Right Deck.
VIRTUAL DECk
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 flash
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 that the
Virtual Deck behaves strangely as Scratch Live
attempts to decode the incoming signal. This
will not cause any problems, but you may find it
distracting. You can unload the currently loaded
track using the eject button next to each Virtual
Deck.
TIP: Use the keyboard shortcut shift-alt-
arrow to unload a track from the Virtual Deck.
