Stereo Mix not cooperating

I am trying to output a mix that came from FCP – I like what I have in STP and want to send an aif for import to FCP.

When I export my aif it does not contain the same tracks as I last heard (mixes in lavs as dominant instead of shotgun, etc.). When I return to the STP mix the tracks previously fine are now simply wrong – hearing seemingly the opposite tracks (R, when I want L). It seems to have something to do with the routing. I suspect it has to do with surround settings embedded in the output as my last project was my first to use surround sound.

I am looking at this because when digging through menus for a solution I see that the multitrack menu gives me an option to add a surround panner, but not the ability to add a stereo panner (the original XDCAm files had L,R audio). It sounds like STP is choosing the wrong channels in the final mix. All sounds fine before I output a mix.

I am looking for how to make sure the project is set as a stereo project and not a surround project, but seem to be missing something. Any thoughts appreciated.

Make sure the output of Submix 1 is set to Stereo 1-2 and not Surround 1-6

Thanks for the response. I do have the submix set to go to stereo. Though the default was to surround (1-6). The system now defaults new submixes to a surround setting (1-6). I hadn't created any surroubnd

A few more details. The project began in FCP. I normally put the shotgun on track 1, lavs on track 2. This came across to STP. When I listen to the mix all sounds as intended. It's not until I export a mix that the track routing changes. After the mix when I listen to the mix in STP or review the aif in FCP (or quicktime) channel 1 now has the lavs and are dominant. Odd. I've had to go with my mix from FCP and forgo the sweetening I've liked in STP as I can't seem to solve this issue. Tomorrow I'll see if I get the same behavior in the desktop G5.

The only other thing I can offer is that sometimes whacky things happen when (some of the) elements, project setting and mix output file are not the same sample rate.

I'm having the same type of problem.

I shoot with an HMC150, Log & Transfer in FCP, add my footage to the timeline and split the stereo pair, keep the track I want, pan to center, continue.

Then I send my sequence to STP. Everything comes in fine. I finish the mix and export a stereo file to bring back to FCP. No matter what I do, whatever was on channel 2 of the camera master will not come through in the final mix. It's like the track is muted. Channel 1 is not coming through instead of channel 2, just nothing coming through where there should be sound from the shotgun.
