It is not 100% solved. In fact I never could get the Dell Vostro 420 as described to work properly. I ended up getting a Dell Vostro 430 with i7 cpu, 8gb, solid state primary drive, Pyro Firewire card, hybrid secondary drives, and still using the NVS 285 cards with 3 monitors. Even with that I had to do Black Viper’s tweaked mods to Windows 7 64 bit to get a useable performance from Cubase with the MR816’s. It’s been suggested I go to the new UR series USB interfaces but I’ve heard they’re just as bad. Thinking about starting from scratch but haven’t made up my mind yet. Perhaps Dell computers are just not DAW friendly.
