Great news. So you finished the release, didn't you? ;-)

I am just casting transparent shadows on QSynth knobs. It was easier to do 
than with povray. Of course the effect is not the same but it is cool. Check 
the last screenshots.

Not 3D but almost ;-)

Modifier keys are really a good idea.

Did i tell you we are also very much interested in mixing Qt and VST. Sure, i 
did. We want to extend the prototyper idea to VST plugins. We have the 
processing part solved but we lack a way of running the Qt interface. Drop us 
a line as soon as you start addressing such problem.

Definitely. :-)
