Hi, we're looking to buy an audio interf for (jazzy/warm) vocals mainly. Needs to be compatible with Windows XP as well as MAC OSX.5.7, preferably firewire or USB 2. It's been recommend we buy a POD Studio™ UX2  with two mic inputs. We really want 4 mic inputs and also wonder if protools is compatible with that particular POD? to record 3 voices/guitar simultaneously). We understand that incompatible software can spoil the recording experience. Our budget is $1000 or 1200 max and we were told that an economical way to purchase protools is to buy one line input M audio mini which comes with protools for around 4 or $500. But then we have only three mic inputs (2 from POD and 1 from M Audio) which probably can't be used simultaneously, or can they? Also we don't know if the protools software is compatible with the POD studio and POD software with M Audio?

Thank you.

Mimi
