The whole GUI part is still unclear, I think I'll borrow some idea's for
it from hydrogen too, and supply Traverso with a "standard" way of editing
ladspa plugins via the well known "plugin settings dialog" :-)

The graphical representation in the TrackView, and AudioClipView ....
Will see how that goes.

Sounds good, all this copying stuff is rather expensive!
I had a look (only very quickly) to the ardour ladspa plugin code, and
there the primary audio is piped to the plugins, at least from what I
could makeup from the code :-)

Ehm, yes and no :-)

I actually forgot about it. Investigating...
