Additional Setup<br />

Hardware<br />

Playback<br />

This section covers general preferences and<br />

adjustments you can make to improve the<br />

per<strong>for</strong>mance of <strong>Scratch</strong> <strong>Live</strong>. From the top of the<br />

main screen, click on SETUP to get to this area.<br />

USB Buffer Size (Latency)<br />

<strong>Scratch</strong> <strong>Live</strong> processes audio in small chunks.<br />

When smaller chunks are used, the movement<br />

of the record is translated into audio more often,<br />

which results in a lower overall system latency.<br />

However, this requires more processing and<br />

there<strong>for</strong>e a higher CPU load, so lower buffer size<br />

settings require a more powerful <strong>com</strong>puter to<br />

produce uninterrupted audio. If you want tighter<br />

control, try decreasing this setting. On the other<br />

hand, if you experience audio dropouts, you<br />

need to increase this setting (or use a more<br />

powerful <strong>com</strong>puter).<br />

Track End Warning<br />

Enable this option to flash the Virtual Deck as<br />

you approach the end of the track. The label will<br />

start flashing 20 seconds from the end of the<br />

record. The Track end warning does not apply to<br />

any tracks under 1 minute long.<br />

Playback Keys Use Shift<br />

When this option is checked you must have the<br />

shift key pressed <strong>for</strong> the playback keys to trigger.<br />

This applies to all keyboard shortcuts, including<br />

cue points, INT mode shortcuts, and the sample<br />

player shortcuts.<br />

Updating Firmware<br />

If a firmware update is available after installing a<br />

new <strong>Scratch</strong> <strong>Live</strong> software release, an Update<br />

Firmware button appears in the Hardware<br />

screen.<br />

The firmware upgrade takes approximately 10<br />

seconds, during which time the <strong>SL</strong> 2 will not be<br />

usable.<br />

Audio Input Level<br />

The input level currently set on the <strong>SL</strong> 2 is<br />

displayed. To change the input level setting, use<br />

the CD / PHONO switch on the <strong>SL</strong> 2. Choose CD<br />

<strong>for</strong> Line level and PHONO <strong>for</strong> Phono.<br />

Recording Bit Depth<br />

Choose to record in either 16-Bit (CD quality,<br />

smaller file size) or 24-Bit (high quality, larger file<br />

size). see “Recording” on page 29.<br />

Sample Rate (kHz)<br />

Choose your sample rate from either 44.1 kHz<br />

or 48 kHz. Use 44.1 kHz by default if you are<br />

not using 48 kHz audio files, as 48 kHz will use<br />

more CPU.<br />

TIP: You can also turn on Caps Lock instead<br />

of using Shift.<br />

Lock Playing Deck<br />

Every DJ’s nightmare used to be lifting the needle<br />

off the wrong turntable in the middle of a set.<br />

This setting helps to avoid the digital equivalent;<br />

loading a new track to the wrong deck. When<br />

this option is checked, you can only load a track<br />

if the target deck is stopped.<br />

Sort Cues Chronologically<br />

The five cue points can be placed in any order,<br />

and can be dragged up and down if you wish<br />

to reorder them. If you prefer to lock them to<br />

chronological order, turn this option on.<br />

Enable Hot Cues<br />

When Hot Cues are enabled, you can set cue<br />

points simply by pressing the number keys 1<br />

through 0 (no ctrl modifier required) from your<br />

keyboard. You can only add cues this way if the<br />

cue point slots are empty. See “Cue Points” on<br />
