RANE SL1 FOR SERATO SCRATCH LIVE • OPERATOR’S MANUAL 2.5.0

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 area.
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,
and includes 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 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 filled when you load the track onto
a Virtual Deck. On slower computers,
you should disable
Autofill overviews
in
the Library tab of the Setup screen.
See
“Preparing Your Files” on page 10
and “AutoFill Overviews” on page 32.
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.

Modes” on page 15.
TIP: Use the + and – keys to zoom in
and out.
TIP: Waveform can be either vertical or
horizontal. See “Display Modes” on page
14.
Kick Drum
In this example, the red part
of the wave represents a kick
drum, while the purple part
represents a snare drum.

Overview
Virtual Deck
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 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.
