Awesome. That clarifies a whole bunch.
BTW, what Mackie board are you using?
Right off the bat, you're going to have a tough time finding 16 analog i/o on a firewire interface. The only one I'm aware of off the top of my head is the
EgoSys HexaFire, which isn't shipping yet.
audioMidi has it for
preorder at $799. Even then, 8 of your analog channels have to be routed via DB25 connectors. Also, as I have never used EgoSys products and therefore have no opinion of the stability of their drivers or gear. YMMV and you should definitely scour the MacOS X audio forums I mentioned earlier for any feedback. Otherwise you might throw a pile of cash down only to learn that the drivers are crappy, which would leave you without functional gear.
If it turned out that they
were spot on reliable, you could pick up two of those units and have a few hundred dollars over for an audio DAW. But that's a whole other pickle.
cpjakes metioned
Motu's offerings, namely the
828 MkII and the 896. Again, you're going to have to cascade multiple units in order to manage 16 multiple analog ins, and the 828 runs approx. $750 which would fit in your budget. The other plus of going with Motu is that it includes a multitrack software package called
AudioDesk. Again, I've not used it and have personally never taken to the Motu/Digital Performer interface, but it would get you started without needing to also purchase additional software. The even bigger bonus is that if you choose to explore your software options in the future, the Motu interfaces will continue to work just fine; they've got CoreAudio drivers, which means that they'll function with any audio software that supports CoreAudio.
Unlike
Digidesign's ProTools.
If you choose ProTools, you're buying in to the entire package: both hardware and software. They do offer a CoreAudio driver, but I've used it with both an MBox and a Digi002. At the moment, it leaves a lot to be desired. However, if you've already had experience using ProTools software and find it to be preferable, you might consider daisy chaining two Digi002 Rack units, or even 1 Digi002 R and 1 'insert_brand_name_here' interface that offers an ADAT 8-ch optical out.
So, how are we doing? Is this helpful? Are you finding yourself with greater or fewer question? Is there any particular DAW that you've heard of or seen that you were really hoping to use?
Best,
