LOGIC 8: Converting Stereo Panning to LCR with discrete Center

[grooveroom]

Well.. it's all in the headline. I did the pre-mixing of a movie-project in Logic (and will never try that again, i guess)... all stereo, with stereo-panning automation.

Now, the studio i'm gonna work with, needs my submixes in LCR-format - with a discrete center.

First, i tried sending my stereo-tracks directly to a surround-bus... result: The stereo-panning (and automation) on this tracks were ignored

Then, i tried sending them to a stereo-summing-bus first, and this bus into a surround-bus: panning worked fine, but i had no _discrete_ center... i always had signals on L and R, even, if the signal was completely centered
It was somehting like stereo + center.

And finally, when changing the diversity (see picture) to zero, i ended up with stereo again...

Is there any way to convert my stereo projekt to LCR? Any hints? I need this center! It looked so simple, at first... aaarh

if you pass it through a Dolby Encoder and then decode into LCRS you could get a LCR output of sorts. Not nearly what you get by mixing that way in the first place, but . . .

Here's an example of two files, one stereo and one LCR (both in LCR format) to see what I'm talking about.

My suggestion would be to drop back and make yourself a surround capable mixer, then open your project in it and re-bus for 5.1. Easiest thing is to make a bus for the C (dialog etc) then stereo buses for music and fx that then you use panners to bleed off into the rears. You could probably do this relatively quickly, and then be able to make 5.1 stems from this project. The resulting 5.1 is pretty simple and ambient but it does work and will make a decent LtRt. You will have to make some level changes, but probably not too many.
