Something I used to use the layers for was creating many layers of a single "part" of a multi-part harmony or even several layers for each of a number of these vocals. This way I was able to use the one bus, the one EQ, the one comp - whatever and collapse the whole thing so I didn't have to look at it if I didn't want to. I sometimes would use layers to comp a part together, but at least as often use a number of layers to create and overall single/multi part, whether layering a bunch of guitar notes to create a harmony Brian May style or a vocal stack or whatever.
I must be missing something. What about the current structure doesn't allow you to do this? You can record clips directly into lanes, or bring clips from tracks into the different lanes for processing by a single effect/bus. Clips within a lane can be slip-edited, have fades added, be split, you can insert effects into individual clips, etc. If multiple clips are selected, you can do things like add a fade to one of them and that fade will be added to all selected tracks. The only real limitations I'm seeing are:
1. If clips overlap on the same lane, only the top one is audible. However, you can add another lane and move the overlapping clip into it if you want to hear that clip
and the clip it overlapped.
2. The composite waveform shown in the main track is the sum of all clips that play simultaneously, which means it looks like it's clipping. (When you hide the take lanes, as far as I can tell the display gives priority to whatever clips are selected, and if no clips are selected, it shows the lowest take that's not muted.)
3. You cannot create a folder and put the Lanes in it, but as you can fold/hide the Lanes into the main track, this doesn't seem particularly useful anyway as the main track is already a "folder track" of sorts.
What am I not seeing? I realize pretty much everyone understands the benefits of the current structure for comping, but I am genuinely confused about what makes Take Lanes unusable for the kind of functionality you describe.
