Tracks out of sync AFTER recording
 
Hi guys,

I have this crazy problem with my Pro Tools station at the moment. Yesterday I recorded a drummer. There were ten drum tracks coming from the live room to the control room. On these tracks, in my PT mixer, I added sends back to the live room to control individual levels for the drummer's headphones. When recording, everything sounded fine. No latency problems at all. I'm using a 128 samples buffer. The drummer played spot on the click and everything sounded great.

However, when listening to the tracks AFTER the recording is done, and after I remove the sends from the tracks because the headphone feed is no longer necessary, the drum tracks seem to be off grid, as if they were moved slightly to the left in the edit window. How is this possible? All sends were set to PRE fader, of course. There are no plugins at all in the session that could provide any latency (or latency compensation for that matter). My system:

Pro Tools 12.5
Mac Mini 2.6GHz
OSX Sierra
Apogee Ensemble

Any help would be very welcome. In this session it is not really a big problem because I'm going to use the drums as the "new" click track and record everything else again, but when dubbing stuff in the future this could be a really big problem!

not being weird or condescending or anything here except trying to understand and help .. BUT !!!

1) can you Prove this ??
2) can you show us in a session that the Clips have moved .. ?? original position and now moved position ??
3) if you put the Sends back in place do the tracks "Move Back" to original position ??
4) how are you basing this observation ??
5) how can we help you figure this out without some physical Proof that this actually happened ??

am i making sense .. i have never seen this happen myself ..

Maybe you were just excited about how spot on the drummer was and how GREAT everything sounded that you didn't notice some of the flaws until you had a chance to listen without the excitement factor.

Pick any audio clip on the timeline and Spot it to original timestamp. If it moves, something is wrong, or you nudged something unintentionally. If it stays in the same place, then it just is what it is.

Yes Steve wins.....use Spot and you will be able to see......if it's moved.

You can also open up a backup session right after you recorded it to see how they laid out right after.

Hi guys,

Thanks for the help. I used the Spot function and indeed all tracks moved just a little bit into the correct recording position. This happened in all eight different sessions I worked with today. Very weird. At least it's fixed now, thanks.

And yes, although I admit I was excited, I could still keep an eye (ear) on the timing :D

there is a Timeline Lock Function that might help, this way you can edit your tracks but they will not shift on you ..

.. and you have 2 choices Timeline ONLY Lock and Timeline and Edit Lock .. please check them out

nice call steve

cheers john

That's funny. I just had nearly the exact problem today.

I recorded a simple guitar riff, and during playback, noticed that the playback was out of sync. I had to slip-slide the clip by a fraction of a beat to work around it.

Resetting the playback engine seemed to resolve the issue.

This seems like it could also be an issue of having latency compensation off, and/or having your playback engine set on a high number of samples

Hi - I don't operate at anything near the level of competency that you guys have, but I have such a similar problem (I believe) that I felt compelled to ask:

I have some bass and guitars that were recorded to a click (.WAV files) and when I bring them into Pro Tools they all start at the same time and are totally in sync

I have some drum tracks that were recorded elsewhere (of course to the same tempo and with a click). When I bring them in to the same session, the drums unfortunately start a few seconds sooner than the other tracks and it is a bit of a mess.

If I can just have the drum tracks start a few seconds later I think I'll be ok. I'm sure there must be a simple way to do this?

Thanks for your patience with me!

Hi Druins. If the drum tracks are all in sync with each other, select them all (and ONLY them) then go ctrl>G to group them. Then you can just nudge them into the correct position on the timeline.
