As requested, I recorded 2 test clips last night; one on the Mac and one on the PC, but I didn't post them. The reason is because in exporting these clips from the recording program, I learned something. The final rendered file on the Mac comes out sounding great, and is exactly what I wanted. The only bad part is that while I'm still in any recording program on the Mac, the sound is not quite right. The sound still is different while monitoring in the recording software and even playing back what was recorded while still in the software. But when you render the file and listen to it, it sounds great. I still don't understand this, but at least I can work with it. Like I said, this happens with 4 different recording programs, so its not the software. The other problem with this is that it makes it hard to use the Gearbox or Podfarm plugin to edit any sounds in in an editing setting while listening to a recording, because the rendered sound will be different. If I want to know what something will sound like, I'll have to get the sound right in the stand alone Gearbox program first, then record unprocessed outputs 3&4, and finally apply the plugin using the sound I edited in Gearbox. The final file will come out right, so at least it's usable, but this is certainly not an ideal scenario for recording and editing after all of the moey I've spent between Line 6 and Apple. I'm wondering if the fact that the ASIO driver is not available for use on the Mac has something to do with it. This is the driver I use in Windows, which always works fine. Maybe someone at Line 6 could check into this. If it is possible to have the ASIO driver available for the Mac, it could very well fix this issue.
