I tend to use a lot of phantom sequenced and there is few thing that are a waste of time and could be easily solved.
1. Making an unique copy of a group of small clips.
Sometimes you have a sequence that are lots of small sequences, and you need to do a change to all of them (ie, add a hihat to all those drum parts). Nowadays if you do an unique copy from them you get a copy with all the references lost. It would be a lot of pleasant you could create a unique copy without lose the phantom copies:
2. Making copies with Insert key of bundled event (maybe this is a bug)
If you duplicate few bundled events with insert keys, the new ones won’t be linked. I discovered this because I usually bundle Curves&Notes… and surprise 😳
3. I already suggested this, but it fits well in this post. I will help a lot that we can see where are other phantom copies, so you won’t screw up your project easily, ie, editing a part that you think that there wasn’t there, or editing a clip you thought you did an unique copy.
