The PowerWave died again. Rather than get all ticked off, I decided to replace it. I wound up getting an M-Audio Firewire Solo. The drivers that came with the unit weren't good for Tiger and wound up crashing my G5. Uninstalling the drivers and downloading the new ones fixed the problem.
So now I have the mixer, mics, pre-amp, and software. I haven't decided if I'm going to use Garage Band or Soundtrack yet.
We start recording tomorrow.
