I'm not that great at C++ or Qt, but after having a look at the code  
I'm thinking along the lines of either:
- making the iterator in AutomationPattern::valueAt static or
- making the iterator a member of the object

...and then check something like ( iterator.peekNext().getTime() >  
_time && iterator.peekPrevious().getTime() < _time )  each time  
valueAt is called and unless so, iterate until it is true (most likely  
1 step forwards every now and then).
