Using a Scarlett Interface on OS X 10.9 Mavericks
Why is my Set playing at the wrong Tempo/Pitch?
Live does not support using multiple audio interfaces, but some workarounds are possible.
General guide for optimizing Windows for audio.
If your audio stream is interrupted, distorting, drop outs and crackles verify, please find here some hints in order to get audio back to normal.
When both programs are open, the Serato Driver Type and Serato Scratch Live Audio Output will automatically be selected once The Bridge is authorized.
Your buffer settings in Serato Scratch Live and Ableton Live will depend on your particular computer and hardware setup.
When trying to run Live as a ReWire slave to Logic I get the following error: "Detected problems with ReWire master application. Live will not behave correctly."
The problem may be a sample rate mismatch between Logic and Live. As a workaround, please try the steps below to let Live know the correct sample rate.
Please check the Preferences Audio tab in Live and make sure you do not have the buffer size of the audio device set high.
This is only possible if there's a standalone ASIO or CoreAudio driver available for your Rane hardware.
