This is about the 30th post (on various forums) I’ve seen asking about this process in Cubase. I posted one yesterday asking about simple group soloing, and why any fx tracks linked to the group’s source tracks aren’t solo’d. Answers were generally old school hardware type logic like “if the group channel doesn’t use the FX channel why would it be solo’d”. Well, because tracks going to the group DO use the FX channel, and when I solo the group I want the FX channels linked to its sources to come along with it. Simple concept that seems to be lost on some people. Solo defeat is an option (in the mixer / timeline…it is not an option with batch export) - but then that has it’s own downsides…like leaving the fX channel open when you solo other tracks that don’t use it. Not good.
What you’re talking about is the same thing. When you try to batch export, any tracks that are going to groups, that are also using their own fx send settings, won’t have those FX included in the export. It’s the same line of thinking here, that FX channels aren’t directly used on the group channel, so they are ignored. It is clear that all through the Cubase programming structure, FX channels are excluded from consideration with batch export / soloing etc. when it comes to tracks routed to groups.
This needs to be remedied, as it pretty much negates the use of batch export unless you have a very limited type of FX channel setup - i.e. fx channels are only used on groups, or tracks that aren’t grouped. This is definitely problem (more like PITA) in projects like film scoring, where groups often encompass entire instrument sections like voice or strings. So when you batch export the strings, brass, voice groups…you won’t get any associated FX channels UNLESS they are on the group. And when you have 50 different FX channel settings for all the various individual tracks (various levels of reverb send on each percussion or string type for example) you will have to export every one of those tracks individually in order to get the whole signal path. As others have pointed out, there is a way to batch export the entire signal path in other DAWs.
So you are correct in what you’re seeing - you CANNOT do what you want to do without manually exporting, or rendering each track independently. This most likely makes batch export useless to you. Which is unfortunate, because it seems like a preference setting, or batch export option that could literally save you hours of time with one preference /setting click.
