Additional setup
This section covers general preferences and adjustments you can make to improve the performance of the ScratchLIVE software. From the top of the main screen, click on setup to get to this area.
Audio cache (seconds)
Use the slider to set the amount of audio that is loaded into memory. A small audio cache will place less load on your com- puter, and the tracks will load faster. A large audio cache will give you a bigger view of the waveform when the main waveform view is zoomed out.
Horizontal waveforms
Check this option to display the main waveform view horizon- tally. The waveform will expand to fill available screen space. If you are using a widescreen computer, increase the audio cache
size to make the waveform bigger.
Maximum screen updates (per second)
This feature allows you to throttle back the screen refresh rate.
Users with slower computers might like to do this if they are hav- ing performance issues. It could also be useful if you want to limit Scratch LIVE’s processor usage, for example if you are running a recording program at the same time. The default setting is 60 Hz, or refreshed 60 times per second. This setting applies to the entire screen (i.e. the Virtual Decks, the Waveforms, the library, and the setup screen).
Playback
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 theplay 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.
Play from start
Enable this to start all tracks from the beginning. 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.
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.
Track end warning
Enable track end warning to flash the virtual deck as you ap- proach 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 page
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.
Braking
This controls how fast the deck stops when play is stopped.
Counterclockwise, the stop is immediate. Clockwise rotation in- creases the stop from a finger grab all the way to a slow turntable
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.
