Note: The SL 1 model has been discontinued.
Note: If this table does not display correctly, see the Scratch Live Data Sheet PDF.
Scratch Live supports all these file formats: Fixed and Variable Bit Rate MP3, AIFF, AAC, ALAC, WAV, OGG Vorbis, CD Audio and direct from the mixer. Record from your mixer's Aux output and immediately scratch as if it was on vinyl. Record direct from vinyl or CD and save as a 24-bit 48 kHz or 96 kHz stereo file.
Easily import your playlists and iTunes library. You can drag from Explorer (Windows) or the Finder (Mac) into the Scratch Live library. The crate and subcrate system helps organize your library and sets. Hot-swap external drives with fast automatic library merging and retention of crates. Browse your music collection by album, artist, BPM, or genre, with optional album art display. Intuitive search function can be applied to any field to find things quickly. Edit ID3 tags with full Unicode support.
Preprocessing of MP3 files is not required except to detect corrupt files or use the auto-BPM and auto-gain functions. Auto-BPM detects tempo information for tracks without it, saving it with each file. A tap tempo button allows you to enter your own. Auto-gain lets you set a target gain on any or all songs in your library. You can also manually adjust individual gain, remembered in each song file.
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. The time and remaining time are displayed in minutes and seconds. The turntable speed as a percentage of pitch shift is on the left, and the pitched BPM is on the right.
Different operating modes can be assigned to each Virtual Deck:
Absolute Mode — exact reproduction of record movement, needle drop through tracks – just like normal vinyl. The beginning of the track is mapped to the start of the record.
Relative Mode —
skip-free scratching, jump to cue points, and pitch bend buttons combined with turntable control. This mode observes the relative forward and backward movement of the record, but does not regard the position within the record.
Internal Mode —
mix with just your laptop using features modeled on DJ CD players. Rewind, Bend down, Play / pause reverse, Play / pause forward, Bend up, Fast forward.
Auto mode — play a sequence of tracks automatically.
With Key Lock on, the key or pitch of the song stays locked at what it would be if the track was playing at normal speed, regardless of the platter speed of the turntable or CD player. Key Lock has scratch detection, so it automatically turns off when scratching for a natural scratching sound.
Variable zoom waveforms centered around current position display horizontally or vertically. Waveforms are colored by frequency so you can distinguish instruments visually. Full track overview lets you quickly find where the beat drops, find breakdowns and choruses, and jump to any part of the song. The tempo display assists with rapid tempo matching of tracks. When the two tracks are matched to the same tempo, the peaks will line up. Beat display emphasizes the transients in tracks -- these are matched up when the two tracks are beat matched. Visual markers can be set for up to 5 cue points per song and triggered from the keyboard. Save up to 9 loops per track -- these loops are saved in the file, and will be present when you reload. Censor expletives on the fly with an instant quick-reverse and catch-up with no loss of timing or pitch.
MIDI control can interface USB controllers with Scratch Live. DJ controller support will vary. Check the latest notes at serato.com for supported controllers.
Built-in help and tips in multiple languages are accessible anytime. There is even a low power warning when running off a laptop battery.
Scratch Live is licensed exclusively to Rane.
PLEASE NOTE: These are the minimum requirements to run Scratch Live with the SL 4. For best performance and for use in professional situations we recommend you buy a higher spec computer. We also recommend Intel processors.
Mac
Windows
*If you have a large library, you will benefit from having more RAM.
Note 1: If you are using Scratch Live's more system intensive features such as DJ-FX or multiple virtual decks and are having issues, you may need a higher spec computer for best results, or make sure you have optimized your system: Windows 7 and Vista / Mac OS X.
Note 2: If you are planning on using HID devices on Mac OSX 10.5 (Leopard), then you must use OSX version 10.5.6 or up. HID devices include Rane mixers such as the Rane Sixty-Eight or TTM 57SL and some 3rd party controllers such as the Pioneer CDJ-400, CDJ-900, or CDJ-2000 CD players.
Note 3: Please read this FAQ if you are looking at buying a computer with an AMD processor: Problems with PCs using AMD processors.
The Rane SL 4 is only sold as part of a complete package. The display box includes:
To get the most from your SL 4, use a mixer that provides four or five line-level input buses.
The Rane MP 2016S Mixer is a good candidate, shown here.
The SL 4 Aux input can record your entire set from your mixer's Aux output.
Continuous control signal on vinyl allows smooth accurate scratching. Scratch Live has the lowest latency vinyl emulation system on the market. It has advanced vinyl groove and stylus modeling algorithm for a sound indistinguishable from the real thing.
Innovative positioning system allows fast and accurate needle dropping. The record has thin marks every minute, and a thicker mark every 5 minutes (played at 33 RPM). These marks assist you when using needle dropping to move through the track.
The Vinyl Scroll track allows you use your turntable or CD to scroll through your crate and pick the next song without touching your laptop.
Four copies of black vinyl are included with the SL 4. Side A: 10 minutes plus Vinyl Scroll track. Side B: 15 minutes.
Four 15-minute control CDs are included with the SL 4.

The RS 6 universal power supply only works with the Rane SL 3 or SL 4.The supply includes different input plugs for the USA, Europe, UK and Australia. The USA plug is attached at the factory — you may need to replace it in your country. To remove a plug, push the button while turning the outer rim counterclockwise. To attach a plug, rotate it to fit into the supply and turn clockwise until it locks in place. This power supply is regulated 7.5 volts DC, 1 amp, using a P6 type barrel plug.
This supply does not work with the SL 1.
Serato Video is a software plug-in for Scratch Live which adds the ability to playback and mix video files. Manage a variety of video clips from within the Scratch Live library and load them onto a virtual deck for control with either vinyl or CD.
The controls allow you to mix clips with a variety of transitions, as well as apply exciting effects to each video clip. The mixed output can be sent to your computer's secondary display for connection to external monitors or projectors.
Serato Video is only available from Serato.
Video-SL Software and Support are no longer available from Rane.
Please contact Serato for purchases or technical support on video products.
Perform your beats: Drag your Ableton Set onto a Virtual Deck in Scratch Live, then use the Deck to control Ableton Live's tempo and playback.
Ableton View: Live's Session View shows up inside Serato Scratch Live. You can launch clips and scenes, control instruments and effects, mix, mute and solo from within Scratch Live. The Ableton View also syncs automatically with your Akai Professional APC40, APC20 or Novation Launchpad.
Sync Player: Sync your Ableton Live Set to an MP3 in Scratch Live and free up a Deck. Ableton Live locks to the groove and timing of the track on that Deck.
Intelligent audio routing: Ableton Live's audio is intelligently routed to your Serato audio hardware; no secondary audio interface is needed.
Important Notes: Free for registered owners of Serato Scratch Live hardware and Ableton Live/Suite 8 (and above). You may use The Bridge with the Trial version of Ableton Live, however after 30 days, a license is required to save, export or use The Bridge. The Bridge is not available for Live Lite, Live LE, Live Intro, APC or Launchpad Edition.
To activate The Bridge: Download Scratch Live 2.1.1 and Ableton Live 8.2. Open both programs at the same time with Rane hardware attached to activate The Bridge online.
The SL 4 is a dual personality device. When using Serato Scratch Live, proprietary Serato Audio Research drivers are used in place of Rane ASIO (Windows) and Core Audio (Mac) drivers. These Rane drivers are used when Scratch Live is not running. The Control Panel for the installed driver is shown above.
The SL 4 has two USB ports, allowing simultaneous connection of two computers. Each port is completely independent. It is possible to run Scratch Live using proprietary drivers on one port while running third-party software using ASIO or Core Audio on the other, in any combination.
Rane ASIO and Core Audio drivers allow the SL 4 to act as a 10-in 10-out external USB sound card for use with multiple third-party software applications supporting Core Audio or ASIO. These drivers are multi-client, meaning they allow multiple applications on a computer to share the device at the same time.
The ASIO and Core Audio drivers are included in the Scratch Live installer as an option.
