transferring between Garage Band to Sonar (or recording with standalone units)

Hi All!

I don't really know if this belongs in the 'getting started' section, but I don't know where else to ask this.  I use Sonar X1 at home.  My girlfriend, who lives a few hours away, has a MAC with Garageband.  I sometimes find myself there on weekends when I don't have to work and she does, and am trying to figure out if there is a way I can record during those days and bring the files back to Sonar.  My estimation, from digging online, is that I can record and simply export each track to it's own wav file and import them into Sonar.  I'm guessing that as long as I set the bpm in sonar to the same as Garageband before I import the files, things should match up correctly.  This would be a necessity, since I would likely be using Ezdrummer on both maches and so I would need the midi to line up perfectly.

Does anyone know of a better method to do this?  The other thing I was contemplating was if there is a standalone unit for relatively cheap ($300 or so) that would work better for this.  I'm just looking for any feedback from folks who have done this type of thing before.

Thanks!

Thanks for your reply.  Yes, i was talking about a standalone unit like a Tascam or Zoom, but wondering if there are any that would seamlessly and quickly allow me to come back and import into Sonar.
