Edit: nevermind. I think I've figured it out...

I just received strad and I love it so far, but I'm a bit confused on how the bow change is supposed to work.

How do I have to set up my sustain pedal exactly? (instrument options-> controller setting?)

when I step on the pedal, I have a feeling it just acts as a normal sustain pedal, which means I can release the key and it still keeps playing. but I can't make out any attack sound that I'd expect from the supposed reversion of the stroke direction of the bow.

All in all, I can't quite get my head around how this is supposed to work yet and would appreciate some clarifying hints.
