Ah, thanks for the .png. That is very helpful.

Well, I'm going to try to use it to prove the point that no GUI is
needed at all. :) I'll see what I can get it to do. I'm also thinking of
using it as a model for a stripped down, simpler version. Probably with
a single Osc->Dist->Filt->Delay->Out signal path to start.

I figure that will make debugging some issues easier. Who knows, I might
even come up with something useful to others. At the very least it will
be a good learning experience.
When I first heard about your xml build system for lasdpa plugins I
thought it sounded like a crazy idea. Now that I've actually looked at a
number of the .xml files and compared them briefly with the generated
.so.c I realize I was simply ignorant. It looks like this system
significantly lowers the bar for getting into DSP programming.
Previously I thought it would be several years more before I knew enough
about programming before I would be able to start contributing. With
your xml system and LADSPA it appears I might be able to dig in and
start off focusing on learning about and comprehending the core DSP
algorithms. I can learn all the housekeeping, gui and systems
programming stuff more gradually. DSP programming is really what I'm
most interested in. The rest of it seemed like a lot of dull drudgery I
would have to learn first before I got around to the fun stuff. Using
ecasound as my host I avoid a whole layer of GUI issues, too. Of course
there is still the midi CC interface, but a GUI host would have to
handle that as well and ecasound's implementation allready seems to work
fairly well. At least for now, I'm not concerned about note events.
In short, I'm pretty excited. :)
Thanks Steve,
Eric Rz.
