LOL

I would _love_ to know how to do it right from the beginning, but isn't that 
supposed to only happen for version 2 ? ;-)

Would be great to have some brainstorming about this, that is expanding the 
existing one :-)

If it all possible, I'm really in to integrate it visually into the 
application, and making it accessible by key actions, and not by menu's, 
though every key action will automatically be added to the 'contextual menu' 
so that's no problem.

Jonatan tried to explain some time ago what he would like to have, that is 
explicit sharing of copied clips. When copying the 'base' clip, the new one 
will get most of it's parameters from the base one.
Editing the gain, edge and stuff will automagically update the copied ones.
This however doesn't work yet, though I lifted AudioClip management to Project 
level (see the project.xml format, and Project::load() and 
AudioSourcesManager class to get an idea)

Indeed!

The plugin 'framework'  (which for now compiles everything statically in) is 
somewhat based on the lv2 plugin structure. You might want to have a look at 
that, see if it also will work with csound, etc.
Plugins at this moment is just an object that can be placed into a 
pluginchain, which in turn can be placed into the audio processing path by 
objects like Song, Track, AudioClip etc.
Routing for this, as well for e.g. Tracks doesn't exist and it would be nice 
to make that work. It's not that hard to do, it's however a big question how 
to make it available for the user in the GUI....

No problem, just see what you can spend on it, and great to see you here!
Will explain some more in a reply on your next mail
