Additional Setup; Playback; Track End Warning; Playback Keys Use Shift - Rane MP4 Operation Manual

addItIonaL Setup

This section covers general preferences and
adjustments you can make to improve the
performance of Scratch LIVE. From the main
screen, tick setup to get to this area.

pLayback

track end WarnInG

Enable track end warning to flash the virtual
deck as you approach the end of the track. The
label will start flashing 20 seconds from the end
of the record. The track end warning does not
apply to any tracks under 1 minute long.

pLayback keyS uSe ShIft

This is checked by default. Unchecking this
option will enable all of these keys without
pressing shift or having caps lock on. This
applies to all cue points (1...0) and cue controls
(QWERTY etc).
See keyboard ShortcutS.

Lock pLayInG deck

Every DJs nightmare used to be lifting the needle
of the wrong turntable in the middle of a set.
This setting helps to avoid the digital equivalent;
loading a new track to the wrong deck. When
this option is checked, you can only load a track
if the target deck is stopped.

Sort cueS chronoLoGIcaLLy

The five cue points can be placed in any order,
and can be dragged up and down if you wish
to reorder them. If you prefer to lock them to
chronological order, turn this option on.

auto GaIn

Auto gain enables you to set a uniform volume
level for the tracks in your library. When a track is
in auto gain mode, the track gain knob appears
depressed.
To enable auto gain, go to the setup menu,
select the playback tab, and then check the "use
auto gain" check box. Provided you have built
your overviews, your tracks will now be loaded
with the auto gain applied.

modIfyInG the auto GaIn LeveL.

Next to the "use auto gain" check box, there
is a drop down menu that sets the target gain
volume level. Use this to adjust the level of your
auto gain.
To find the optimum setting, load a track with
an average volume level onto one of the virtual
decks. Now play the track, and note the volume
and LED lights inside the software.
The idea is to have the track volume sit just
under the clipping point (indicated by the LED
meter red lining). If the track is too quiet, unload
the track, then go to the setup screen and boost
that auto gain db value more.
Once you've made that adjustment, load that
same track onto the virtual deck again.
Notice that the volume knob has turned up and
the volume is louder.
Keep making those adjustments on that
particular track until its just below the clipping
point. Once that is set you don't need to adjust
the target gain level ever again.
Because the track you used had an average
volume level, most of the other tracks in your
library will be around the same volume. You may
still need to turn up the separate track volume
when you load a quieter track onto the deck and
turn down the louder tracks but once you've
made those adjustments Scratch LIVE will
remember them the next time you load the file.
tIp: Slightly too quiet is always better than
too loud. If your Led meter is in the red, it is
likely that it is clipping. not only does clipping
not sound very nice, it can damage your
equipment.
note: your overviews need to be built by
version 1.7.2 or later for auto gain to work.

hI-fI reSampLer

This significantly reduces digital distortion at very
slow or very fast record speeds, increasing the
CPU load slightly. This option is off by default,
the old resampler is used when switched off.

pLay from Start

If this setting is not enabled, freshly loaded tracks
will continue to play from the point the last track
was at. This option is on by default.

InStant doubLeS

This allows you to quickly match the playhead
position of two tracks. With this option set,
when you load a track on one virtual deck that is
already loaded on the other virtual deck (it must
be the same file), the playhead will jump to the
position of the track that was loaded first, with
the keylock state and looping settings copied.
This setting overrides the play from start and
play from first cue point options.

pLay from fIrSt cue poInt

Enable this option to start all tracks from the first
cue point. This setting overrides the play from
start option.

audIo output

By default the output of Scratch LIVE is stereo.
You can also select mono output. This setting is
saved when you exit Scratch LIVE.
