Hi, I'm just looking to record vocals with a condensor mic and MIDI and was wondering if anyone had any experience with this product. I'm not really looking for professional grade, because I'm only using it for a hobby. It just has to be decent and sound nice on my headphones http://www.musiciansfriend.com/product/EMu-0404-USB-2.0-Recording-Interface?sku=242516 I'll be using my Macbook which is running Leopard with an external firewire drive connected. The one thing that stuck out to me with the 0404 is the ability to use an external power source. I figure that would help make my laptop run better becuase there's less stress on the USB, is that right? Any other product suggestions would be nice also.. thanks.
