Hudba is a project mainly written in JAVASCRIPT and PYTHON, based on the GPL-3.0 license.
node + music
node + coffee script + music + you
Hudba was originally a Tornado based project. In this form, it made its way to a pretty useful alpha state.
I decided to port it to node, however, before working any more on it (primarily to take advantage of asynch/socket.io stuff).
The node version is not yet usable.
