This is just a way to say "Thank you William, for creating such great products!"

Support Open-Source Projects
per month

I'm slowly starting to create projects that are open-source, and for that I need the support of fans. You will receive Binary files for those projects before I make those public.

All My Products
per month

New Products, Sounds and Music. You get it ALL. Plus early access to Alpha and Beta versions. The ultimate level on supporting my work. This is the same thing as the Rent-to-Own option from the Wusik site, so be sure to read that description as it explains how this works.

About William Wusik Kalfelz

Hello there, I'm William Kalfelz (WilliamK), founder of Wusik Dot Com, creator of several virtual synths and also other projects such as Beat707.com.

For details on all my music related products, visit the following site.


I have been doing live streams on Twitch, coding in C++ and JUCE. Be sure to follow up there using the link below.


Thank you all for collaborating.
Don't forget to visit my music site: http://www.Kalfelz.com

Who am I? I'm 44 years old and I have been working with music related projects since I was 10. I started to code nearly 20 years ago and haven't stop since that. This is a passion, not something that makes me rich, therefore I need all the help from the community in order to continue doing what I do best.

I also like to talk about some personal things that most people try to avoid: I'm Bipolar, with a Personality Disorder. Why I always talk about this? Is my way of trying to help others with the same problem, as, sadly, this is still a Tabu on our society. :-( Below is a link to a video where I talk about the problems I have faced and how I have recovered to a near steady pace.
