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:
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.
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.
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.
NOTE: It is normal for the tracking
indicator to be red when cueing or
scratching.
Tap Tempo
For tracks with no BPM
information, there is a tap tempo
button displayed where the BPM usually
is, in the song info area. Pressing alt-
space bar activates the tempo tapper
(press alt-space bar a second time to
activate the tempo tapper on the Right
Virtual Deck). Tap the space bar along
with the beat. After you’ve tapped the
first beat, you can switch to double time
tapping, half time, start of each bar etc.
The range is set by the first two taps, after
that you can switch to any steady rhythm
you feel comfortable with – quarter notes,
half note, whole notes. Esc resets the
BPM, Enter saves the BPM to the track.
You can use the mouse if you prefer.
Your CD player or turntable’s pitch slider
doesn’t need to be at zero, we do the
math for you. You can also use the tempo
tapper when no song is loaded, for finding
the BPM of regular records, for example.
Key Lock
When Key Lock is on, the key or
pitch of the song stays locked at
what it would be if the track was playing
at normal speed, regardless of the platter
speed of the turntable or CD player. Key
Lock has scratch detection, so that it
automatically turns off when scratching
for a natural scratching sound. Turn Key
Lock on or off by clicking the button to the
top right of the Virtual Deck.
TIP: F5 and F10 will turn Key Lock on
and off for the Left and Right Decks
respectively.
Repeat
Use the Repeat function to repeat
the song across the entire length of
the control record.
TIP: Short “loop” samples can be
turned into a continuous track using
the Repeat function. The loops must be
less than 10 seconds long, and cut at
the start and end of a bar.
Censor
Use the censor button to “mask”
parts of a song, or use as a special
effect. When you press the censor button,
the track starts playing backwards from
that point. When you release the censor
button, the track plays forward from the
point you would have been, had you not
pressed the censor button. Censor is
available only in REL and INT Modes.
Eject
This ejects the track playing or
loaded from it’s Virtual Deck.
Autoplay
Click the
Auto
button to enable
autoplay. With this setting turned
on, when one track finishes playing, the
next track starts automatically. Load from
a crate to play through the songs in that
crate, or from your library to play through
your library. Autoplay works in both REL
