When Key Lock is on, the key or pitch of the song stays locked at what it would be if the track
was playing at normal speed. Key Lock has scratch detection, so that it automatically turns off when
scratching for a natural scratching sound.
The Key tag for the current track is displayed (if available).
Playback allows you to select which playback mode you want. Single means once the end of the
track is reached you will hear silence. Cont means when the end of the track is reached the next
track in the playlist will be loaded and playback will continue.
Tap Tempo
If a track has no BPM information stored, the tap tempo box is displayed where the BPM is usually
displayed in the track title bar.
Pressing alt + space bar activates the tempo tapper for the left virtual deck (press alt + space bar
a second time to activate the tempo tapper on the right virtual deck). To calculate, tap the space
bar along with the beat. After you’ve tapped the rst beat, you can switch to double time tapping,
halftime, start of each bar etc. The range is set by the rst two taps, after that you can switch to any
steady rhythm you feel comfortable with – quarter notes, half note, whole notes. The esc key resets
the BPM, the enter key saves the BPM to the track. You can also use the mouse if you prefer by
clicking in the tap tempo box and clicking the mouse button in time.
NOTE: You don’t need to be at Zero on the pitch slider, Serato DJ Intro does the math for you.
Track Overview Display
This area provides a complete overview of the waveform of the track and includes a marker to show
the current position within the track. This view is useful for nding transitions within the track. The
waveform is colored according to the spectrum of the sound; red representing low frequency bass
sounds, green representing mid frequency sounds and blue representing high frequency treble sounds.
You can jump to different positions within the track by clicking on the track overview display. Grey
lines behind the overview show the length of the track; a thin grey line every minute, and a thick grey
line every 5 minutes. If you have not analyzed your les the overview will be lled when you load the
track onto a virtual deck.
TIP Analyze les before you play.
Main Waveform Display
This area provides a close-up view of the track, including color-coding to show the frequency of the
sound; red representing low frequency bass sounds, green representing mid frequency sounds and
blue representing high frequency treble sounds. Click and hold on the waveform to ‘scrub’ or make
ne adjustments to your position within the track. The main waveform is zoomed around the current
position in the track.
NOTE: The waveforms scale with the pitch slide on your Serato DJ Intro controller to make it easier to
see when beats are aligned and in time.
