Hi
Thank you for getting in touch.
Do you accept the controller device settings dialog window when you connect the SX 3 to your Mac?
The device is being used in external mixer mode and natively supported (as the device is an external mixer). Please make sure it is setup correctly as pre cueing is treated exernally by the device itself.
If you have any question please contact us right away via support@algoriddim.com
Cheers
Lukas E.
