Hey fellas. So, this is the last major piece of the puzzle for me. I've decided on a Mac Powerbook G4 for my computer, Logic Pro 7 as my sequencing software, and now I need to pick a i/o hardware unit with firewire connection I've been looking at the M-Audio 410, but would appreciate some advice based on my needs: -4 inputs (at least two need to be mic preamps...XLR, 1/4 balanced, 1/4 unbalanced)..... -? outputs (I guess I need 2 for sending to speakers...not sure if I need more....not doing surround sound). -Firewire connectivity -Excellent sounding preamps -Phantom power -Headphone outs (obviously) -Maybe some effect loops/aux. sends for rack units??? Not sure... -Midi connection....or should I just connect my midi keyboard to the powerbook via USB? ....I think that's it.
