Mixdown goes out of sync

I have 26 minutes of music, split into 8 section over 19 tracks. I'm using 1-4 vsts/DX effects per track. The sections play fine by themselves, but after I mix down, some things seem to go out of sync. If I mixdown (selected) each track seems fine, but I can't mix down the whole deal without it getting weird.

I'm not running anything but AA3 and the plugins, and I'm not even using 1/4 of my ram. Any ideas?

No I don't have any idea, but I think that at a bare minimum, we need more details. Could you tell us how far out of sync are we talking here? The other thing to ask is whether, if you mix this down without all the effects, the same thing happens? Is is just one track that seems to be wrong, or several?

Because on the face of it, this shouldn't happen. There have been reports of huge track placement errors when a lot of tracks are played at once, and a single one added, but I don't think that this is in any way related, judging from what little you've told us.

The reason for the 'mix it down without effects' question is to try to decide whether it's an effect that's causing this. If you play a track with an effect on it that causes it to play late, then when you do a mixdown of this, the playback error would be corrected - so the track would then appear to be early, if you see what I mean...

Thanks for the reply Steve.


I did try to mix down 100% dry and the problem still occurred, it was the 2nd tom and one of the overheads. I ended up locking every file in place, rebooted, and tried again. It worked this time around, so I'm wondering if it had to do with the files not being locked? I had the same problem monitoring the tracks as well, but I didn't think it would have affected a mixdown. Very weird.

I must admit that I'd assumed that you'd locked the tracks, and I should have mentioned that. Although really, this shouldn't make any difference - they ought to mix from the positions they're in regardless of whether they are locked or not. But if locking them works, well hey...

You would think, right? I'd never had problems like that in 1.5, and just recently went to 3, so I'm still about 2 months into learning it. I suppose I should have tried out 2, but the interface at the time seemed so laggy on my computer, it was completely unusable. Whether it was a clean reboot, or locking the tracks, I don't know, but it works.
