Can I use Focusrite Scarlett with Audacity?
In short, you can use your Focusrite interface with Audacity, but you will only be able to use the first two inputs and outputs. As OS X's inbuilt audio driver (Core Audio) is able to support multichannel input/output, Audacity will see all inputs and outputs of any Scarlett / Saffire / Clarett interface.
