I'm having a problem with a project that has been recorded on both Pro Tools and Vegas. I've discussed this problem with a couple of engineers (including a former Chair of Berklee's Engineering and Production Dept.) and we just can't figure this out. If anyone here has any thoughts on this I would greatly appreciate it.
Here's the problem:
We recorded basic tracks on a mac w/ Pro Tools.
The tracks were copied to a mac formatted external drive, which I took home and copied the files from to my PC, using a program called Trans-mac to convert the files to Wav.
The wave files were then copied to CD as PC data files, and loaded into various band members' PCs using a few different versions of Vegas (one guy used Vegas 1 & 2 for some of the overdubs, until I made him get Vegas 4, and I used Vegas 3 for awhile, now I'm using Vegas 5) to record overdubs. Soundcards used were a Delta 1010, an M-Box and I'm not sure what the third one was. No external clock was used for OD's, unfortunately.
Then we went back to the first studio and loaded our Vegas-recorded overdubs into Pro Tools. However, on playback in Pro Tools the overdubs start out in sync, but they become progressively more out of sync as the playback continues, and yet there is no detectable pitch shift. By the end of the song the overbubs are waaaayyyyy off (like many measures off - not even slightly subtle).
I can take all of the very same project files and open them up on my PC in Vegas 5 and they are perfectly in Sync for the duration of the song.
All recording was done at 44.1kHz, some at 16 bit, most at 24 bit.
We've gone home, carefully checked for any possible problems and found none (everything lines up and locks in perfectly when opened in Vegas) and then recopied the files and brought them back to try to get them to work correctly in Pro Tools on 3 seperate occasions now,and sure enough, the same thing happens every time. The stuff overdubbbed on the PC has a different tempo than the stuff recorded in Pro Tools when all are played back in Pro Tools, and yet there is no difference in pitch (aaaarrrgggghhhh!!!!!).
And just to keep things interesting, this is only happening on about half of the songs, and despite many hours of troubleshooting I can't really find anything particularly in common with how either half of the songs' overbubs or basics were recorded.
I have a workaround that'll get me through the project, so that's not a problem. I'm presuming there's user error here somehow, but damned if I can figure out what it is.
I'm just wondering if anybody out there might have a clue as to what's going on, because I sure don't. This seems like an impossibility to me.
This is making my head spin!!! I need a coupl'a aspirin....
