RANE TTM 57SL MIXER FOR SERATO SCRATCH LIVE • OPERATOR’S MANUAL 2.4.4

Troubleshooting and

Frequently Asked Questions

The audio playback is dropping out /

clicking / popping

Scratch Live is not getting a clear signal

from vinyl, or your computer is not able to

process 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 true,

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 33.

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.

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 left of the Estimate button)

to the right until the noise stops. See

“Calibrating Scratch Live” on page

12.

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 to be 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.

In the USA, you may order these from the

Rane Factory Store at rane.com.

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.

The le may be damaged, and may need

to be deleted from your library. Please go

to the forum at serato.com 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.

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.

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 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\_Serato_ on a

Mac, and My Documents\My Music\_

Serato_ in Windows XP, and Libraries\

Music\_Serato_ in Windows 7. If your

library contains tracks that are stored on

a drive other than your boot drive, a folder

called _Serato_ 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. See

“Scratch Live Backup” on page 31.

I have pink ﬁles which don’t play

These are les which Scratch Live thinks

are missing. You can use the Relocate

Lost Files feature in the Ofine player to

re-associate these with their new location.

To do this you can either: drag the le

itself from Finder/Windows explorer onto

the button to relocate an individual le,

drag an entire folder onto this button,

or press the button (this will search all

connected drives for all the missing les in

your library).

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 36.

To keep up with the latest tips, visit

the Ofcial Scratch Live Forum online at

serato.com.
