I agree with st10ss, if I’m reading them correct. If you currently have one effect that covers for example both dialog and effects, say a reverb, then best practice is to duplicated the verb and have two of them, one receiving from dialog and outputting to the dialog group, and one receiving music only and outputting to the music group (etc).
There are several benefits to this and one of them is the ability to export proper stems. In addition to that you also don’t have to do it in multiple steps in a queue since it’s all in ‘parallel’; you just do a batch export with all stems simultaneously. And on top of that you won’t need to create a solo arrangement for each queue and send to/ set that in Export Audio Mixdown’s queue list - you just do the selection of sources instead.
Btw; I take it this is for music, not post, right?
Sure. We did discuss this earlier this year - or something similar - and I think there are some caveats worth remembering when working that requested way though.
