What a hell to deal with USB devices like the EMI 2/6. And what a strange idea from Emagic to have spent so much energy for promoting USB audio gear. It's true that their latest Mac drivers are more reliable and offer better latency (especially on LAM 5.3 for OSX, if you don't mind dozens of CPU peaks at the smallest buffer settings...) but they are far from being comparable to the Audiowerk Mac driver in terms of CPU hunger and software monitoring quality - and this even at lowest latency under OSX 10.1.5. What we need from Emagic is a more powerful Audiowerk with an even smaller latency, and its compact Firewire declination with midi in/outs and some good preamps for example. No more USB. I have bought my EMI 2/6 in February, have tested it in many Logic configs - Win Me, XP, OS9 and now OSX on a G4 DP 800 - and 6 months later I can certify one thing : selling USB audio devices to professional musicians is simply a nonsense today. Yann le Bihan PS : before answering "no problem here", just make a comparative test if you have access to both AW8 and EMI on a Mac...
