I already wrote about
Jeskola Buzz,
several times.
It's a software music studio. You add different machines and effects to your workspace, connect them the way you want, add the musical patterns for those machines, and insert the patterns in the tracker to make a music track.
It's very easy to learn how to use it - it has a wonderful help.
I made a new track - "void star" (like in void *).
