I'd be interested.

It would likely take me some time though, and maybe some guidance, but
it's something I want to learn. I dabbled in C but can only read simple
code. I start to study computer science next week, which will give me
access to the library at least, to K&R and a bunch of others.
The lectures at university are mostly in java but C is required at some
point, and I guess it's better to start learning it sooner rather than
later, besides, it seems to be needed for all the neat audio stuff ;)

So yeah, I guess I should get the code, put it in a git repo and just
start hacking...
