Logic wont play back audio regions under certain tracks.

Hello! I am rearranging my audio files (throwing them all to my secondary hard drive, where I record to ). I did this, and now certain audio files to do not play back in my logic projects, but there is no warning that says the file cannot be found--which is what I am used to happening. At that point I would either hit the Search button, or the Manually Find button. Instead, the region appears as per usual, just with nothing playing back. I know I could import the audio back into my projects manually--which would be fine for those that start at a specific, clean-cut time, but what about all those spliced and diced regions that are cut up and laid out all over the place!?

I discovered new details to the weirdness . . .

It seems, in the few projects that I relocated audio, that the affected regions cannot be played back unless I move them to another audio track. What??? For example, the vocal track in one song, which is all set up with its plugins and such as Audio Track 2, will produce no sound unless I drag it to another audio track, say Audio Track 3 or 4. It is bonkers!! What the heck is that about?

This is what happened in all of the projects affected by my source audio rearrangement. Sure, I could easily just copy my channel strip settings to a new track, relocate my audio region to it, and hope all goes well thereforth, but I would much rather get to the root of this oddity so it doesn't somehow buck me later.

What do you think it could be?

Oh yea, in one of the projects, all the other audio tracks seem to play back fine, except for the recorded bass track. Okay, so just to check, I drag the bass audio to another track--yep, it does play back. But I realized that the track that held the bass region (Track 4) is actually playing back the vocals (which are also playing back normally in their intended track). I initially didn't notice the extra vocals underneath my normal vocals track, with their low-key bass plug-in settings. Funny thing is, there isn't even a region on Track 4 any more! How is it playing anything back at all?? Not that it makes any more sense that it would be playing back vocals with a bass region.

Also, the fact that Logic Pro keeps quitting unexpectedly does not inspire much confidence. This has just been lately, and I've only been playing with these projects lately, trying to figure this out.

Is my Logic haunted? =(

I welcome any and all objective suggestions! I am feeling just the slightest bit overwhelmed by this odd behavior.

Thanks!


(i checked, but did not see that the tracks were muted in anyway, including the region itself)
