Not exactly. Your _GUI_ is a separate executable. A DSSI GUI is a 
separate process that transforms GUI events to OSC messages and 
viceversa, doesn't touch any audio data. The processing part of the 
plugin is within a .so library that is dl-opened by the host.

Yup, just a lot of boilerplate for discovery and communication, 
shouldn't be too difficult.

Send them to the list, maybe we can offer some advice.

Making it a qt-designer plugin makes it very easy to integrate it in 
other's projects.
