Not that I can see. I wouldn't expect too much in this area, but I was disappointed to see no over all track level envelopes (unless I'm missing something). Each event has a Fade In/ Out and level envelope but IMO that's not enough even on an iPad.... and $50 is a 'real' app price.
Hope it comes later
