Scratch Live

Rane Serato Scratch Live (SL or SSL) is a so-called vinyl emulator and a component of a digital vinyl system, by the companies Rane Corporation (hardware) and Serato Audio Research (software ) was developed. In this case, a control signal is supplied in the form of an analog audio signal from a record or CD to the software. This converts the code to the control of various audio and video signals. A change of the signal by a forward or backward movement of the record or CD (eg by scratching ) affects this 1:1 to output the audio signal from. In addition, the software includes features such as Loop, cue points, etc. The audio signal generated by the control signal is given by the computer via the USB port on the Rane audio interfaces and output from these as an analog signal. The hardware is sound card and dongle for the software at the same time.

Software

Scratch Live can be, even before you have the necessary hardware to download from the official website. So you have the opportunity to organize their music and configure the software. However, the user interface in this case has only one player to listen to music directly in the software can and put eg CUE points or Loops. In addition space of the integrated songs can be scanned to detect possible defects and incompatibilities. Only when you connect the hardware, two virtual decks appear to work. A complicated registration, activation or binding to an account is not necessary, because the hardware dongle ( and copy ) is. Scratch Live has a speed counter ( BPM), real-time speed adjustment, up to 5 cue points and 9 loops per song and the integration of iTunes playlists. Other functions such as ID3 tag search, sorting by various criteria and a cover display in its own browser also available. Every feature of Scratch Live can also be controlled with a MIDI device, and so facilitate the operation.

With the official expansion Video -SL (VSL ) is the output of video files is also possible. The plug-in uses QuickTime and can therefore largely use all of QuickTime-supported formats. In addition, Rane TTM 57SL called a blender appeared that the legendary TTM 56 connects with Scratch LIVE. The mixer has the necessary hardware built right and makes it easy to control the software with various potentiometers and buttons. In September 2012, published a new version of Serato extension named Serato Video ( SV). The performance of the extension has been improved on the one, and enlarged the scope of effects and control options. Users of Video -SL had the opportunity to convert their license for free in order to access the new features of Serato Video.

Hardware

USB audio interface

With a USB audio interface to the computer, the control signal fed from the turntable or CD player. The signals from the computer are here converted back into an audio signal to pass these on to the console. With Serato Scratch Live compatible audio interfaces are manufactured by Rane SL1, SL2, SL3 and SL4, which can be installed in any existing setup. Furthermore, also the sound mixer from Rane ( Sixty Eight, Sixty Two, Sixty One and TTM 57SL ), in which an audio interface is already installed, compatible with Serato Scratch Live. For this no additional audio interface is needed.

With the Thru mode of audio interface is the ability to pass the analog audio signal of the plates or CDs directly to the audio mixer. The content of existing recordings can be continued to be used.

Noisemap records and CDs

The records and CDs contain a special code that Serato Noisemap. It is not here as comparable products at a time code, but a LFSR -based pseudorandom code maximum length, which is used for position determination. To this end, the audio signal is similar to the fax or data cartridge, acoustically picked up and interpreted as a data stream.
