This series is indeed a 2-in/2-out mixer; all the channels get mixed down to stereo (hence 2-in). I'd say it's great for live performances, where all you need to master is a stereo mix, but it is very annoying, I find, for studio recording for this reason: the monitor outs listen to both USB return and master mix at the same time, and one dial controls the gain of both. This means that, when you are recording a new track while listening to already recorded tracks, you can't take the instrument you're presently recording out of the monitor mix.

I think the Edirol UA-25 is a much better interface for home studio recording. Only two channels, but you can turn direct monitoring off. It's also not quite as noisy as the MW-10/12, as someone already mentioned.

And of course, if you want to record multi-track (e.g., drums or a live performance that you're mixing later), you'll want to look at a FireWire or PCI interface. Presonus Firebox and Firepod are good FireWire machines, and the M-Audio Delta 1010 is a good PCI one.

Wow, I don't know whether to vomit or pee myself. Maybe I'll do both. That is some really neat stuff.

I wonder if it's available as a retrofit for '90 VWs? probably not. I'll have to make my own, I guess :)
