One track won't follow group edits.

Hi Everyone.

I've recorded 3 tracks of bass using Logic's groups feature. We had one bass playing through a DI, with the through output split through an amp and pedal separately, so 3 simultaneous tracks = 1 performance.

I used the group feature to group all three tracks and set "record" as active in the group settings, so as to insure all the recordings would be identical.

I've checked editing and quantize-locked audio as well, and one of the 3 tracks isn't responding to the group edits.

I've used this same method on several other songs with no issues. Can somebody help me out with this problem?

How do I resolve this? Would unpacking and repacking the folders make any difference? I'd like to avoid that unless absolutely necessary because it would be a pain.

Thanks,

Lorenzo
