Whenusing Serato Scratch Live, proprietary SeratoAudio Research drivers are used in place ofRane ASIO (Windows) and Core Audio (Mac)drivers. The included Rane drivers are usedwhen Scratch Live is not running.The SL 4 has two USB ports, allowingsimultaneous connection of two computers.Each port is completely independent. It ispossible to run Scratch Live using proprietarydrivers on one port while running third partysoftware using ASIO or Core Audio on the other,in any combination.Rane ASIO and Core Audio drivers allowthe SL 4 to act as a 10-in 10-out external USBsound card for use with multiple third-partysoftware applications supporting Core Audio orASIO. These drivers are multi-client, meaningthey allow multiple applications on a computerto share the device at the same time.ASIO and Core Audio drivers are not availableon a machine while Scratch Live is running. Touse multi-client ASIO or Core Audio drivers with athird-party application while using Scratch Live,you can connect two computers to the SL 4 withone running Scratch Live and the other runningASIO or Core Audio application(s). Connectingboth USB ports to the same machine is notrecommended.The ASIO and Core Audio drivers are includedin the Scratch Live installer as an option. Theoption to install them is checked by default.ASIO (Windows)The SL 4 uses a low-latency, multi-client,ASIO device driver to interface with softwareapplications other than Scratch Live onWindows operating systems. Multi-client ASIOallows different audio software applications tosimultaneously stream audio to and from theSL 4. If the same playback channel is selectedin more than one application, the driver mixesthe audio from the different applications beforestreaming it to the device.The driver Control Panel may be launchedfrom the Windows Control Panel.
