Recording vocals seperate from main music Mac
I can't keep lugging the Mac Pro about, so ideally I'd like to record the vocals in a suitable (different) space on to a laptop, then import the resulting audio files to the main project on my Mac Pro.
The idea is that I'd do a stereo reference mix of the music in Logic Pro, bounce it and copy that audio file to a project on the laptop (using Garageband or Logic Express to save cost).
With that project set up at the same tempo and sampling rate, I'd then record the vocals using the laptop. From there I'd copy the vocal audio file(s) and drop them into the music project on the Mac Pro, where I'd add any effects, processing and do the final mix.
First question - would this work? As long as I recorded the vocals in a project set to the same tempo and sampling rate as the music, would I have any timing or sync problems when adding the vocal audio files to the original music project?
Second question - if so, can anyone recommend any portable, Firewire 800 audio interfaces which would be suitable for recording the vocals on to the laptop? It would ony need to be 2 input channels maximum, but with at least one XLR input and phantom power.
Any advice gratefully received!
