that's why i added the montage part after i though more about it. the peak data is saved in a separate file but i'm not sure how the montage is saved. i'm going by the wording. save to file sounds like a wave file is being saved, while save mixdown as, sounds like it's adding the mix info as well.
plus i'm only guessing.
<edit> because i was writing during the last post
it could be saving pointers, markers, and references to to original waves if i'm right about the wording deal.
