In Cubase 5, the default behavior for editing a track in Vari was for a section to auto-play when you selected. As you moved the note up or down, it played at that pitch and gave you a nice preview.
Cubase 5.5 doesn’t seem to do this, and I’m not sure how to turn it on. It’s probably a simple option I’m just overlooking but I’ve looked on the forums here and run a couple of Google searches and no luck. Working in Vari without this behavior is much much slower.
