I need to do some ambient background music soundtracks for a friend's visual arts movies. Wusikstation seems like a good fit for this, and it's only $50 right now.

So, I'm wondering--what else is it useful for? In addition to some really nice presets, it can also play samples. Most of my music is rock--will it be useful outside of electronic/ambient music? I'm always looking for good keys, drums, etc. for rock.
