I often get requests to export around 8-10 stems (Drums, Guitars, Synths etc.) for the music I mix and master. I remember this working flawlessly in Nuendo a few months back. I previously worked in Logic and used to solo each track stack and export individually which was very time consuming but worked reliably.
In Nuendo, I usually set up Groups for each Stem I need to export. So I’ll have a Group for Drums, Bass, Guitars etc. I also have FX Tracks for sends such as Parallel Compression, Reverbs, Delays etc. All of these are then sent to a MASTER Group track, where I usually have my mastering plugins. And this finally goes to the Stereo Out.
When the client requests for stems, I would then use Batch Export to select these Groups and it would render out in one go with all the correct FX Tracks assigned/sent to each Group/Stem.
I’m on the latest version of Nuendo and for the past two songs, this method doesn’t seem to work correctly. The levels are all out of place. When I solo the Group track, it doesn’t seem to solo the compression or reverb sends assigned to the individual tracks. They stay muted. Individually hitting solo on the track/folder seems to work. I don’t know if this is how it’s always worked.
I’m not sure if I’ve messed up the routing somehow or if this is a bug? Since I had no choice, I Solo’d each group of tracks separately and rendered the stems individually. But, here’s the issue, when I compare the sum of all the stems against the stereo master file, it seems to be louder by a couple of dB. Almost as if the final limiter isn’t being applied.
Any thoughts on what I could be doing wrong or how to improve the batch export workflow?
