Control Vinyl Spares

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.

Control CD Download

Four 15-minute control CDs are included with the SL 4.

You can burn your own control CD if you have a burner and the right software after downloading the big control file (132MB). Scratchlivecontrol.zip requires an unzip utility to open, and includes two files. Scratchlivecontrol.wav is a stereo 44.1 file that you can drop into any burner application -- however, the track select portion at the end of the audio file reqires a special start time on a second track to function correctly. If you have Sony CD Architect(TM), you can load the scratchlivecontrol.cdp file and it will incorporate the correct second track timing. When using any other application, do not adjust the levels, make sure no auto-levelling is turned on, don't downsample or try another format, or the control signal won't function.

Rane Serato Scratch Live

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 current 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. zZounds is an authorized dealer of Rane products.
