There's no way I'm gonna be able to swing the bucks for a MPB , especially with the added cost of an interface, recording drive and software. Not that I haven't done research....the problem is 50% say you can do this while 50% say you can't. Maybe i can get a clearer picture here. I'm not looking to record 16 simultaneous tracks at once...more like anywhere from 1 to 4. Bone of contention #1: You can't daisy chain audio devices. (ei, interface and recording hd) Macbook has 1 fw port. Some say (and some interface manufacturers say) don't daisy chain. On the other hand, some say that they haven't had problems. Also, some say that using one of those external fw hard drives that has a usb/fw hub built in allows the use of interface and hd together into the computers single fw port. Bone of contention #2: Don't record on the internal application/system drive. Well, sure..ideally, but it doesn't mean you can't, right? Just don't expect super performance, yeah? I've recorded on the my bands pc using only the system drive alright. Others say they record on the macbooks/minis/imacs system drive alright too. Bone of contention #3: Don't use USB for audio interface. (sure USB 1.0..never. But what about USB2.0?) Well, manufacturers DO make them, so they must work, right? Again, some say..."stay away". On the other hand, keyboard magazine claims its a myth that USB 2.0 doesn't work well for audio. Granted they max out at 4 simultaneous recording inputs, but if thats all you need.....? Thanks for any input.
