The whole history of this thing was based around Cubase not having an equivalent to Protools playlists.
The old workflow for stacking multitrack recordings people had to contend with in Cubase way back when was putting all your record tracks into a folder track and then duplicating the Foldered tracks for each take.
Using Audio ‘Parts’
Most people I know, opted for the FolderTrack duplication when working with something that is live band recording, or drum takes… Because ‘Parts’ can only show and edit one track at a time which is only useful for solo-source editing like lead vocals.
The secondary function of ‘Parts’ is to have finished comps/edits/arrangements/beats in which you maybe don’t want to bounce the edits, and or, have event-muted variations at hand that you can duplicate/copy around the project and create ‘Shared Copies’.
This has now become the primary function of audio ‘Parts’ with the introduction of Track Lanes, which is the more logical and efficient way to work in conjunction with TrackVersions. There really wouldn’t be a reason to still be doing editing in parts, unless you’ve ‘Shared Copied’ a bunch of multi-take rough material/loops you need to edit… But honestly, even then, I’d probably break it out of the ‘Part’ and edit in TrackLanes and then re-shared-copy it to what it was before.
Do it how you want, but if you were working for me, you’d be doing your primary editing on TrackLanes. Completed edits of musical material that consists of multiple broken events (like a drum beat) or musical lead ins like fills that aren’t a full bar, would become parts.
