Wow. That's really cool. It's exactly what I wanted to do ages ago.
The best names I thought of were JackBay and MetaModular - you're
welcome to either.
Here are some GUI ideas I thought might be cool or useful:
The wires would look even cooler if they were splines, so that they came
out of their ports horizontally and gracefully curved their way to their
destination :) It looks cool and feedback loops display better. (if
you're using something like a GTK canvas it's pretty easy too)
When ardour is in use I imagine a feature where the output ports of a
program can appear as a seperate module from the input ports would be
handy (so that [ardour output]->[effects chain]->[ardour input] can be
drawn without a loop).
Being able to shift-drag to move all the wires connected to one port
directly to another would be really handy sometimes, as would click-drag
to copy connections (I often find myself doing these things by hand in
other apps).
Another potentially handy idea is to make it so that if a module is put
next to another so that the input ports of one line up to the output
ports of another, they automatically become connected.
A very ambitious idea would be to allow LADSPA plugins to be embedded
into the UI so that to the user it looks as if they've been put straight
into the JACK graph. In reality they would not be connected via JACK at
all of course.
Anyway, it looks great, I can't wait to try it out.
