Ah... I see where the problem lies.

If I create a new project and put a single three minute CD file on a single track and render it as a stem with a reverb effect, it takes about 34 seconds.

If I put the same file into a project which has 12 tracks each with a CD song on a track, and render it as a stem (just the single track containing the same test file) it takes about 5 minutes 14 seconds!

Either I'm doing something wrong, or there's a bug here. I was pretty careful about settings (eg master mix is not ticked, bit depth is the same, etc etc).

While doing this test I did a quick check to ensure that procedures which should produce identical files (procedures being consolidate, apply FX as new take, and render) do produce identical files, by inverting the output of each method against the other. To which Justin would reply "of course they do!" but it's good to know that he's not kidding.

[EDIT:- Hmm, I think when you do a stems mix, it does the master mix whether you asked for it or not. That's the bug.]

[2nd EDIT:- Yup, testing confirms that is what is happening].
