You can have oneshots play at speeds other than 1 in the timeline. That means that you can play loops that have been misplaced into the oneshots category at different tempos. I found some big room EDS loops in the oneshots section and play them at double, half, and various other tempos.
It's very useful. You can change the tempo of a track without changing the pitch of vocals using time stretching. Keeps the voice from sounding weird, and the poor quality of stretching isn't that noticeable with small bpm changes.
