i have the manual for both. I assume the Tascam will be able to do this easier than the Otari...as the tascam is much newer than the otari. 
 

Oh good. Someone smarter than I will have to help you with the syncing though. I'm a little confused as to how if the original drum tracks and the mixdown of the drum tracks ended up different if there was a clock in play or how to correct it but there's gotta be a way. As far as syncing there is a section in the manual on syncing to external devices. Good luck.

thanks for you help. there was no sync track used when tracked initially. I'll look into it and post when I figure it out. it will be a bit before I can dive fully into this.

However without any syncing from the tape decks I think unless you can figure out what Rail was referring to that you may want to just try the map/audiosnap procedure I mentioned. I couldn't see the drift being THAT bad so it should be rather simple. Unlike what I'm trying to do which is correct WILDLY fluctuating tempos. Now that is a pain.
 
Cheers.

Now that I think about it more here's something else that might make it easier. If the mixdown of the drums and the overdubbed tracks are in sync import all of it so you can use the stereo drum tracks as your guideline. Then you if you set your snap grid settings to snap to transients you can simply pool the transients of the multi tracked drums and snap them to the transients of the stereo drum tracks either by hand or with some luck automatically. I've only briefly looked at some of the auto quantize for stuff like this but you may be able to extract the tempo from the stereo drums to use as your snap grid and just quantize the multi track drums to that. It's a little involved but it would save time if you can figure it out.

I think what you've just suggested is genius...and likely the solution. I'll try it...it makes good sense as the exact transients are on each set of recordings....just not in sync. 
 
Thanks again and I'll let you know how it goes this week I hope. 

Right on. Please do. I'm sure others may want to perform this same function so it's good to have it archived. Cheers.
