. as far as multi-audio-trax you may want to find DDClips
, the Win7 version; its free.
With it you can add up to 64 audio channels and sync them up to the video. Once
you get the Audio Tracks to line-up, you can THEN bring all those tracks into 10-Pro
and have "it" compress the sounds into Surround-Sound AC-5 -or- AC-7.
. One of the nice features about DDClips
is that "it was designed to work with multi-layered
tracks from its inception. ( its designed to work specifically with Audio Alignment issues. )
.. Pro-10 is not exactly a multi-audio nightmare but, it comes close T_T .. Primiere is the true nightmare with Audio!!DDClip Pro 3.67
