We've uploaded a short video with me playing The Wiinstrument's Drumstiicks mode:

I'm not a drummer, but I think the instrument is real fun if you practice a bit.

We're still working on 0.2 – expect a release soon!
0.2 will be released with the following features (among others):
- Use pitch and roll rotation axes of Wii remote and Nunchuk as MIDI controllers
- A better graphical frontend
- a tiny sampler (load own WAV files into the Wiinstrument instead of a MIDI setup)
