Looked on the website. OK, looks like the Scarlett MixControl is a stripped down version of Saffire MixControl.
Another item of note is that Scarlett interfaces are generally USB whereas Saffire interfaces are Firewire.
So I can say for my USB 6i6 Scarlett, no issues. Since I don't have a firewire version I would not be able to test for you. I can only ASSume that you would be good since I was on USB.
