Ok, here’s something that showed up in Wavelab 10, and hasn’t been fixed yet (as of 10.0.7):
When multiple clips are assigned to a group together, trimming any edge of any clip in the group results in the same edge getting trimmed in every other clip of the group.
I have an intro clip intercut with a verse 1 clip, intercut with a chorus-to-end clip. I group the three clips so I can slide my edited song around in the montage as a single element. If I trim the front of the intro to a later start, the front edge of the verse 1 clip, and the front edge of the chorus-to-end clip will also be moved later and I now have two holes in my song. (undo). If I slide the back edge of my intro clip earlier, the end time of clip 2 and clip3 will likewise be offset. I’ll have a hole after the verse 1 clip and my fade will be cut off.
This grouping problem is avoided by creating a super clip, but I’ve run into some unpredictable timing behaviors when opening a superclip and swapping the associated files, and I haven’t had time to suss those out yet.
