TROUBLESHOOTING
AND FREQUENTLY
ASKED QUESTIONS
THE AUDIO PLAYBACK IS DROPPING OUT /
CLICKING / POPPING
Scratch Live is not getting a clear signal from the
record, or your computer is not able to process
the information quickly enough. Go to the setup
screen and check the scope views. When the
record is playing, the circles should be round,
and the value in the bottom right corner should
be 100%. If this is not the case, you need to
calibrate.
SEE “CALIBRATING SCRATCH LIVE” ON
PAGE 12.
Try increasing the USB audio buffer size if
your computer is close to the minimum spec.
SEE “USB BUFFER SIZE (LATENCY)” ON PAGE 30.
Clean your needles! This is the most common
cause of audio drop-out. Because you are
playing the same record over and over, the
needles will get dirty more quickly than usual.
THE THRESHOLD GOES TO THE FAR RIGHT
WHEN I CLICK THE ESTIMATE BUTTON
Make sure the needle is on the record and the
record is stopped when you click estimate. If
the slider goes hard right and stays there, you
most likely have an earthing problem with your
turntables/mixer. If you cannot eliminate this
problem, use rel mode over abs mode.
THE TRACKS ARE PLAYING BACKWARDS!
The inputs (from the turntables or CD players)
are the wrong way around. Try swapping red and
white wires at one end.
I CAN’T GET THE SCOPE VIEW TO SHOW
NICE CLEAN CIRCLES
Select phono as the audio input level in the
setup screen if you are using vinyl. Check
your needles and make sure they are clean. If
the circles look fuzzy, try cleaning your control
record. If the Scope View shows a line instead
of a circle, Scratch Live is only receiving a signal
from one channel — check all your cables, and
the connection between your cartridges and the
tone arm. You can order replacement control
records from your local distributor. If you are in
the USA, you may order these online from the
Rane Factory Store at rane.com.
SCRATCH LIVE MAKES A STRANGE
“DIGITAL” NOISE, EVEN WHEN NO TRACK
IS PLAYING
Scratch Live is interpreting background noise as
record movement. Go to the setup screen and
move the threshold slider (located to the left
side of the estimate button) to the right until the
noise stops.
SEE “CALIBRATING SCRATCH LIVE”
ON PAGE 12.
THE FIRST TIME I PLAY A NEW TRACK, IT
TAKES A WHILE TO LOAD
Scratch Live has to read the entire le and create
a le index the rst time it is loaded. This may
take a few seconds for longer les. After the rst
load, it should load instantly.
SEE “PREPARING
YOUR FILES” ON PAGE 14.
I HAVE A PARTICULAR MP3 THAT WON’T
PLAY / PLAYS BADLY / TAKES A LONG TIME
TO LOAD / CRASHES THE PROGRAM. WHAT
SHOULD I DO?
The le may be damaged, and may need to be
deleted from your library. Please go to the forum
at scratchlive.net and notify the support team
that you have a bad le. By reporting damaged
or corrupt les, you will help the developers to
improve Scratch Live’s ability to play damaged
MP3 les in the future.
SCRATCH LIVE FREAKS OUT WHEN I USE
THE MASTER TEMPO (KEY CORRECTION)
FUNCTION ON MY CD PLAYER
Scratch Live interprets the signal coming out of
the CD player, and uses this information to control
the play back of the les on your computer. Any
audio processing performed on the signal before
it reaches the hardware interface, such as key
correction, will scramble the signal making it
illegible to Scratch Live. Key lock is available in
Scratch Live.
SEE “KEY LOCK” ON PAGE 17.
I GET A LOUD SCREECHING SOUND LIKE A
FAX MACHINE AND NO MUSIC, WHAT AM I
DOING WRONG?
That is the sound of the control signal — make
sure you are listening to inputs D1 and D2 when
using Scratch Live.
I WANT TO BACKUP MY LIBRARY AND
CRATES OR MOVE THEM TO ANOTHER
MACHINE, SO WHERE ARE THEY STORED?
Your database and crates are stored in the
folder Home\Music\ScratchLive on a Mac, and
My Documents\My Music\ScratchLive on a PC.
Crates have the le extension .crate. If your
library contains tracks that are stored on a drive
other than your boot drive, a hidden folder called
_ScratchLive_ will be created in the root of that
drive, and a separate database will be made in
this folder. If it is a removable drive, the tracks
will only appear in your library when the drive
is connected.

I HAVE CUE BURN AT THE BEGINNING OF
MY CONTROL RECORD, DOES THAT MEAN
I NEED TO REPLACE IT?
No, use the track start offset function (in the
setup screen) to move the point at which tracks
begin to a position further into the vinyl.
SEE
“VINYL START OFFSET” ON PAGE 32.
