ya it works, it has craped out on me a few times but it is useable, i would reccomend buying a new interface though, oh ya and i don't record through it (can't comment on that), just use it to mix, digidesign has some sub-par coreaudio drivers so don't expect the greatest stability

Can you tell me which new interface specifically?

Download the core audio drivers from the Digi site, reports are that they are not great, but some people use them.
