I'm William Kalfelz - aka Wusik - and I started this project several years ago (2001 to be more exact). Wusik Station (now in version 9 for both Win/OSX) is a fantastic synth and my leading product. Wusik 8008, my second major release, is a sample playback modular synth featuring an easy-to-use interface. My other products include a great VST/AU sequencer/host called Wusik SQ200 and a chainer called Wusik P2000. I also work (as a hobby) with Arduino DIY based projects at Beat707.com. Finally, if you want to know more about me, you can watch this video where I talk about myself and discuss Bipolar Disorder.
