Rane SL4 SL4 Owners Manual for Scratch Live 2.5.0 - Page 13

Main Screen Overview Virtual Deck The Virtual Deck shows everything about the speed and position of a track. As the vinyl rotates, so does the line on the label. The circular progress bar around the edge is a visual representation of the position within the song, and can be set to flash to warn you that the track is nearing its end. The time and remaining time are displayed in minutes and seconds. The pitched BPM (BPM with pitch adjustment multiplier added) is shown on the left of the Virtual Deck, and the turntable speed as a percentage pitch shift is shown on the right of the Virtual Deck. If the track has no BPM information, pitched BPM will not be shown. If you are playing regular vinyl, notice the Virtual Deck behaving strangely as Scratch Live attempts to decode the incoming signal. This will not cause any problems, but you may find it distracting. You can unload the currently loaded track using the Virtual Deck eject button. TIP: Use the keyboard shortcut shiftalt-arrow to unload a track from the Virtual Deck. USB Sources & Analog Inputs Each Virtual Deck in Scratch Live has a unique input / output source, which you can change to suit the layout of your DJ setup. To set a USB Source in Scratch Live, click the USB Source dropdown box above the Virtual Deck. E.g: If a Virtual Deck has "Channel 1" selected, this means it is controlled by the turntable / CDJ plugged into Input 1 on the SL4, and the audio from Scratch Live will be sent to Output 1. The same applies to the other channels: 2, 3, and 4. You may want to change your display to 4-Deck Stack Mode to assign all the Decks at once. See "Display Modes" on page 15. Visual Aids When the track is playing several waveforms are displayed. Each shows a different aspect of the track being played. Tempo Matching Display The Tempo Matching display area provides a helpful tool for beat matching. Scratch Live detects the beats within the track, and places a row of orange peaks (for the track on the left side) above a row of blue peaks (for the track on the right side) in the Tempo Matching display area. When the two tracks are matched to the same tempo, the peaks will line up. The tempo display is aligned with the beginning of the bar, so the peaks keep their relative position as the track plays. This display does not show the relative timing of the beats, only the tempos of the tracks. The peaks will still line up when the tracks are playing at the same tempo, but are out of sync. Track Overview Display This view provides a complete overview of the track waveform, and includes a marker to show the current position within the track. This view is useful for finding transitions within the track. The waveform is colored according to the sound spectrum - 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 (disabled in ABS Mode). 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. The overview will be filled when you load the track onto a Virtual Deck. On slower computers, you should disable Autofill overviews in the Library tab of the Setup screen. See "Preparing Your Files" on page 11 and "AutoFill Overviews" on page 34. Main Waveform Display This view provides a closeup of the track, including color coding to show the frequency of the sound; red representing low frequency bass, green representing mid-frequencies and blue representing high-frequency treble sounds. You can also switch to a three-band spectrum view by holding the ctrl key and clicking on the waveform. Click on the waveform to 'scrub' or make fine adjustments to your position within the track. This applies to INT Mode only, and may be useful if you wish to set cue points in your tracks without your turntables or CD players connected. The Main Waveform is zoomed around the current position in the track. See "Cue Points" on page 18 and "Scratch Live Modes" on page 16. RANE SL4 FOR SERATO SCRATCH LIVE • OPERATOR'S MANUAL 2.5.0 13
