I just listened to the video demo of the Audia, and it brought a couple questions to mind, if you are at liberty to answer them.
Do the live player phrases stream from the harddrive, or are they considered part of the 300 meg wave rom?
Do all styles use live players, or is it only 1 or 2 styles per genre? A couple Latin phrases use real guitar while most use synth guitar, a couple pop styles use live drummer while most don't, etc..
How do the live players respond to odd or unusual chord voicings? Mostly what I heard on the video demo was major and minor. What happens if I play a Flat 9 sharp 11 chord?

Has electric guitar been provided as live players? I heard a lot of acoustic demos, but is there electric as well?

Can we make our own styles with live players? This would only be possible I guess if the live players streamed from the harddrive and weren't part of onboard wave rom.

As you can tell, this whole real musician thing in an arranger really resonates with me, and I'm just trying to figure out exactly how in depth this feature can be manipulated/utilized.

Thanks,
Rory
