Troubleshooting and Frequently Asked Questions

Scratch LIVE hardware is not recognized

It takes ﬁve seconds for Scratch LIVE to detect the hardware. e hardware can be unplugged at any time; you do not need to exit

Scratch LIVE before disconnecting the hardware. Use the supplied USB cable, longer lengths are not recommended.

On some Windows machines each USB port is treated separately, so you will need to install the driver separately for each USB

port.

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 page Manual–5 for details.

You should also try increasing the

USB audio buﬀer size

if your computer is close to the minimum spec.

Clean your needles! is 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 the

estimate

button. 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

relative

mode over

absolute

mode.

The tracks are playing backwards!

e inputs (from the turntables or CD players) are the wrong way around.

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. You may also order these in the online store at www.rane.

com if you are in the USA.

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 (lo-

cated to the left side of the

estimate

button) to the right until the noise stops.

The ﬁrst time I play a new track, it takes a while to load

Scratch

LIVE has to read the entire ﬁle and create a ﬁle index the ﬁrst time it is loaded. is may take a few seconds for longer

ﬁles. After the ﬁrst load, it should load instantly. See Build Overviews on page Manual-18.

I have a particular MP3 that won’t play / plays badly / takes a long time to load / crashes the program. What should I do?

e ﬁle may be damaged. Please go to the forum at scratchlive.net and notify the support team that you have a bad ﬁle. By report

ing damaged or corrupt ﬁles, you will help the developers to improve Scratch LIVE’s ability to play damaged MP3 ﬁles in the future.

My USB will only output audio for about ten seconds then quit. I can still control Scratch

LIVE with the control records, but I get

no audio output

is is a known Windows XP bug. Included in the Windows Update SP1 (Service Pack One) download is a ﬁx for the XP USB

1.1 bug. For more information visit www.support.microsoft.com

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 ﬁles 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 correction will be built into Scratch LIVE in the future.

I get a loud screeching sound like a fax machine and no music, what am I doing wrong?

at is the sound of the control signal — make sure you are listening to the line outputs of the hardware interface.
