Strange problem with audio/midi tracks after copy/duplicate
 

Hello!

I discovered a strange Problem on Protools LE 9.0.3/9.0.5!!!

independent of session or Computer:

After copying OR duplicating Audiotracks/Miditracks a few times (sometimes after the first, sometimes after more copies) the right end of the track is not on the Grid anymore. --> you can only see this when zooming to maximum!!

Settings are on "Grid", tried it with "Sample" based and "Tick" based too.

I also tried it on another Computer with PT 8 and a PT HD5 and the Problem did NOT appear! Its bad, because you cannot just copy/duplicate right on, you need to check every right edge of your Files manually, because if you just copy on, your sound will change after 3-4 minutes.

I checked it with a Click Audiotrack set perfectly on the Grid and put into a Group, with the Edges perfectly cut. After duplicating about 3-4 minutes you will hear its sound starting to change -> i have put it over a midi beat, which was set correctly "manually" until the end.

This means: your Music will NOT sound the same at the End.

Its very little but i think this is not ok. Its causing phase Problems and other Things because its happening randomly.

Any Ideas??

Thank you very much!! :)

I have the same problem with Pro Tools.. the bar doesn't reach the end of the grid after duplicating just a few bars twice!
Does anyone know if there is a fix for this?

From the manual:

Sample Rounding and Edit Operations

When audio material in Pro Tools is samplebased,
some amount of sample-rounding may
occur with some edits when the Main Time
Scale is set to Bars:Beats. This is most evident
when you need audio regions to fall cleanly on
the beat (as when looping) and notice that the
material is sometimes a tick or two off. With a
few simple precautions, this can be avoided.
To ensure that selections are precise aligned to
the grid for looping, copying, duplicating, or repeating,
consider the following:
