Vinyl emulation in Pro Tools
Scratch Studio Edition has been Discontinued
Scratch Studio Edition has been discontinued. Serato is concentrating its engineering efforts on the award winning Scratch LIVE instead.

Pro Tools Hardware Requirements
The latency of Scratch Studio Edition is limited primarily by your IO hardware's buffer size, converter latency, and session sample rate. The following are the latencies that result from the different Pro Tools systems available:
- TDM / HD systems - 9ms latency.
- 001 systems - 9ms latency.
- 002 systems - not tested yet.
- MBox - works fine but has a 40ms latency and only supports one turntable.
- PT Free - works but has extremely high latency. This configuration is totally unsupported, as there is no control over the quality of the I/O hardware.
Setting Up Your Studio
Connect the stereo outputs of your turntables to the inputs of your audio interface (do not use a phono preamp, and don't connect it to your mixer). Next, connect the stereo outputs of your audio interface to the line inputs of your DJ mixer.
In order to be able to record your performance, you will also need to connect the outputs of your DJ mixer into another set of stereo inputs on your audio interface.
You may need to set your tonearms a little heavier than usual i.e. heavy enough that the needle never leaves the record, but not so heavy that it heats up significantly. Both produce poor tracking.
Note: if your sample plays backwards (in external mode) this means the inputs from your turntables are connected the wrong way round.
Earthing
It is extremely important that you ground your turntables. Do this by connecting the ground cables of your turntables to the ground posts of your DJ mixer. All DJ mixers with turntable inputs have built in grounding points for this purpose.
If you do not ground your turntables, the control signal will be noisy and the tracking of the record position will be erratic.
