So I just go myself a scarlett 2i4 and when I try and use it with my mac everything is distorted. Apparently it’s using an ASIO driver, however this device does not come with ANY drivers. So I’m thinking I need to somehow get Cubase to use the device with Core Audio rather than ASIO.
According to focusrite site, it does come with drivers, and there you can also find a tipps and tricks concerning audio glitches under MAvericks - and still Mavericks is not supported by Steinberg yet.
