Calibration
cAlIBRATIng ScRATcH lIVe
When setting up Scratch Live in a new
location, calibrate the software to the
background noise picked up by needles,
cables and CD players. Play music
through the system from any source.
1. Put one Virtual Deck in InT mode, load
a track, press the play button, and turn
up the mixer volume and sound system
as loud as you will be playing your
session.
2. With audio playing through your
speakers:
a. When using a turntable, place the
needle on the record with the motors off
and switch to the
SeTUP screen.
b. When using CD players, pause the CD
and switch to the SeTUP screen.
3. Press and hold the estimate button
for each side, letting go when the
threshold setting is stable (usually about
one second). In situations with lots of
background noise, the threshold will
need to be higher.
4. Start the motors, and adjust the l/R
balance and P/A balance next to each
calibration scope to adjust the shape
of the inner ring. Use the scope zoom
slider (
1x to 16x) to zoom in or out as
necessary. Note: If you have trouble
getting the rings circular, try cleaning
or changing your needles. If the image
appears as a line, then one channel
of the turntable is not working. See
examples of SCOPE READING AND
FIXES in the manual.
5. Check the percentage (%) in the bottom
right corner of each calibration scope,
indicating the percentage of readable
signal — this number should be 80% to
100% when your system is calibrated
properly.
These are the basics of calibrating. If
you run into any problems or questions,
we really recommend reading the
CALIBRATING SCRATCH LIVE in the
manual. If you aren’t seeing good circles,
refer to the SCOPE READING AND FIXES
pages in the manual.
After your setup is calibrated properly
you are ready to import music. See
IMPORTING AND PLAYING MUSIC in the
manual to get started.
Since Scratch Live is controlled by an
analog signal, there is no guarantee of
what state that signal will be in by the time
the software gets to interpret it. Therefore,
Scratch Live needs to be able to handle a
wide range of signals, and be configurable
to use them optimally. Calibrating is just
configuring the software to your situation.
calibration is equally important for both
vinyl and cD users of Scratch live.
