I think we are really approaching the desire to be able to insert effects on Files and/or Clips.
So a plug-in could be applied to the whole File in the Pool, adjusted and done.( eg Noise Reduction or EQ on a long Interview.) Adjusting settings at the file level would filter down to all Events in the Project.
If the Plug-in was applied to an Event in the Project, the option would be there to apply it to just the Event, to all events which referenced this audio, or to the whole file. Settings adjustments to the Plug-in in a single Event would have to give the option of making the adjustment just to that event (a new instance of the Plug in ) or making the adjustment wherever that File is used. I find that different pieces of a single ‘take’ need different settings especially if microphones are in motion ( boom, wireless ) or people are moving around.
Its not that different to the idea ‘Processing’ material, just easier to adjust in the context of a mix. It would save having dozens of Tracks … one per Plug-in setting. Indeed it still could be “processing” ( i.e. not real time) if the list of applied Plugins still appeared in a list of Clip Inserts so they could be adjusted … moved, deleted etc like they were Track inserts!
The now forgotten application SoundTrack Pro by Apple could do this more or less … and it was very, very powerful in that respect. Of course it didn’t run for more than 30 minutes without crashing … but the realtime-for-tracks, and rendering-for-clips effect structure was great IMO.
This type of capability is exactly what I want from Nuendo. It isn’t exactly a music-making feature, but Nuendo shouldn’t be a music-making app. That’s Cubase!
Oh… and Track Sorting by Role ( character name, shot size, element type … ) .
