[chuck-users] chugin tutorial or docs?

[Steve Morris]

Cool. Thanks. "Katja's helmholtz~ pitch tracker in Pd;" Even the math is
well documented which is unusual.

I also see no reason that ChucK can't be a serious music tool. It is
already pretty sophisticated as well as being quite mature in the sense of
showing very few bugs. I was hoping to do serious things with it.
Unfortunately want I want to do amounts to extensions to the core model
more than using existing features. It is unfortunate that there is so
little support for people who want to do so. Dynamic library support is
probably what I need. It has already been implemented but like ChuGins is
basically undocumented.

ChucK has been around for a long time so it is not clear that things will
change. This may be paranoia but ChucK seems to have all the stigmata of a
project tightly controlled by a small group that wants to maintain control
for their own narrow purposes and vision. I'm sure it is not malicious. It
is just that a small group has limited resources and need to stick with
their priorities. There's nothing wrong with that. They're doing the work.
ChucK is free and open source so it is hard to complain. But it makes it
less valuable to people who want to push in different directions. In a
different project those people would be implementing things that the core
group might not have time for. Other groups support their superusers
because they give back. Here they are ignored.
