Re: [LAU] mackie onyx blackjack

This is good news! I'm looking for a good USB 2-channel audio
interface for christmas and I was almost decided on the M-Audio Fast
Track Pro, which should be working out of the box with a 3.1 kernel,
too. But I reckon the Mackie is a way better device. It only lacks
96kHz recording, but I think I can go without that.
