Ok, so......
I'm working on a session and during tidyup I accidentally delete the vocal track in it's entirety.
I'm currently working at data recovery but forget that for now.
Now, it's not the end of the world; I can have the chap re-sing it, but I'm thinking smart and realise that I have a recent stereo bounce with vocals and a session save point from exact that moment which is now missing vocals.
The bounce region is still selected in the session and everything!
So I rebounce the stereo wav but this time without vocals.
Line up the two wavs in a daw, flip polarity of one and BAM..I've got my vocals back, right?
Well...All acoustically recorded instruments cancelled out as expected and left nothing but vocals, but virtual instruments that come in later don't cancel!?
I can't get my head around this at all.
The virtual instruments appear to be out of time by about 9ms in the vocal-less bounce and even if I manually compensate, they still don't null. It's like they're just slightly different somehow.
I can completely rule out changes to the session. Even the file properties show date created and date modified as being identical.
I'm using ProTools 10.
I know everything is lined up perfectly and the volumes are perfect etc.
Any thoughts, chaps?
