Hey people - I apparently shot myself in the foot and now I'm looking for some way to get out of the predicament. Here's what happened: I recorded some audio tracks to a click at 105 BPM. At some point a tempo change to 100 BPM was inserted into the project by mistake without my noticing. A bunch of other audio clips were then recorded at the new 100 BPM tempo but totally in sync with the tracks that were recorded at 105 BPM. When some MIDI drums were inserted into the project, the timing issue became very obvious because all the audio tracks were out of sync with the MIDI. So I tried removing the single tempo change so the entire project was at the original 105 BPM. After doing that, the MIDI drums and the audio tracks recorded at 105 seem to sync up okay but the audio tracks recorded at 100 BPM were totally out of sync with the 105 BPM audio tracks. I then tried changing the 100 BPM clips to groove clips so they would stretch with the tempo change. After that, not only were they out of sync but they also sounded like Diver Dan (that's "under water in a metal helmet" for you younger folks who never heard of DD... .) Anyone know how/if I can get all the tracks to sync up together at 105 BPM and sound like they did originally?

Select the clips you want to stretch from 100 to 105 bps and open the AudioSnap dialog. Click on "clip follows project tempo" button.

Thanks bitflipper - AudioSnap was worth a try but it produced some additional weirdness. I ended up changing the clip property from "musical" to "absolute" for all audio clips before deleting the tempo change. That seems to have done the trick so far. Audio is in sync with MIDI.

This is probably because you've only partially completed the process.

You need to bounce to clip any A/S clip - this will use a much more benign algorithm and eliminate most of the artifacts you're hearing.

Thanks Bristol_Jonesy - I'll give A/S more of a fair shake when I have some time to spend trying to figure it all out. I've tried a few times but it must be beyond my pea brain to comprehend. Actually, thinking about it, some A/S shenanigans could happen tonight... in the same song there is a section where the guitarist strayed from the click a hair. I understand that AudioSnap is good for tightening that up so this sounds like a good opportunity to learn something new.

Yes - A/S is, or should be, the perfect tool for nudging the odd note(s) into the correct place (timewise)

If the 2nd batch of audio clips were recorded truly in sync with the first, as you said in post #1, then they are already recorded at 105 bpm. You don't need to change the tempo of any audio tracks. Starting with the version of the project that has all audio tracks in sync, make sure none of the audio tracks are enabled for stretching (or "clip follows tempo"). Then you can delete the tempo change. Assuming the midi tracks were "inserted" as opposed to recorded, they should come back in sync with the audio. Then start nudging.

As may not be the solution you are looking for. If the tracks recorded at 100 bpm do not start at the 1st bar they will be offset once you removed the tempo change. You may need to slide them to the proper starting position to get things back into sync.

Yes, thanks - this is what I ended up doing. It took me a little while to figure out how to prevent the audio from stretching. For some reason I had to reinsert the MIDI to get it in sync - didn't even try to figure that one out...

Yes, initially the clips were offset after removing the tempo change. But, I didn't want to have to slide them around. Instead I issued UNDO of the tempo change and changed the affected clips from "Musical" time base to "Absolute" time base - then deleted the tempo change. That caused the clips to stay where they were in relation to the song.
