RANE SL2 FOR SERATO SCRATCH LIVE • OPERATOR’S MANUAL 2.4.4
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. 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.
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 11
and “AutoFill Overviews” on page 34.
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, 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 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 18
and “Scratch Live Modes” on page
16.
TIP: Use the + and – keys to zoom in
and out.
TIP: Waveform can be either vertical or
horizontal. See “Display Modes” on page
15.
Kick Drum
In this example, the red part
of the wave represents a kick
drum, while the purple part
represents a snare drum.
Snare Drum
Beat Matching Display
This view shows the position
of beats within the track. When
beat matching, this view helps
align the downbeats of the two
tracks. The markers are matched
up when the two tracks are beat
matched.
Example:
Here 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.
1.
Start the track playing on the Right
Deck. After a few seconds, blue peaks
appear in the Tempo Matching display.
2.
Adjust the pitch of the right turntable
until the blue peaks sit under the orange
peaks in the Tempo Matching display.
Once they are aligned, the two tracks
have the same tempo.
3.
Next align the markers in the Beat
Matching display. Watch the color of the
items passing by in the Main Waveform
display. Remember that a kick or
bass drum will be red in color, and a
snare drum will be green or blue. This
technique will by no means guarantee
perfect mixes, but may help to speed up
the process of beat matching.
Master Gain
The master output of Scratch Live
can be controlled using the master
gain control. This adjusts the
output volume of all tracks played. Ctrl-
click the knob to reset it to 12 o’clock.
NOTE: For best results, set the master
gain to 12 o’clock, and adjust the
volume of individual tracks using the
track gain adjustment. See “Track
Gain” on page 14.
33 / 45 Speeds
Set this to match the speed
of your turntable for normal
playback.
Tracking Indicator
The tracking indicators
on the main screen show the quality of
the signal coming from the control record
or CD. The length of the bar indicates
the speed of the record or CD. The
color indicates the amount of position
information Scratch Live is receiving.
When you are playing the record at normal
speed, the tracking indicator should be
grey. If it is mostly red there is a problem
reading the control signal. Make sure
your needles are clean, and check the
calibration in the setup screen.
