I think I'll stick with my Wavedrum for these sorts of noises. Cool to see something that physically does what the Wavedrum ostensibly physically models.
I have the current (rerelease) model. It's a lot of fun although I have only used it as an overpriced snare in any of my recorded tracks. I did use it in a couple live performances and it worked well there to give weird abstract percussive noises.
