Thanks for checking, I really have the feeling I'm missing something
small here :)

Yep, missing something small seems to happen to me frequently.  I'm jumping over to my Linux machine and will give it a go.
 

The SVN is here:
svn checkout svn://svn.code.sf.net/p/avwlv2/code/trunk avw.lv2

(Ingen is the host I use to test them)


First things first.  Your plugin, after modifying ttl files, works fine in Jalv.   For ingen support, your best bet might be to add a Trac ticket on  drobilla.net.

Ok, so I figured out the problem...   the GUI ttl file should look something like this (with a portNotification setting)

<http://avwlv2.sourceforge.net/plugins/avw/scope/gui>
        a guiext:GtkUI ;
        guiext:binary <scope_gui.so> ;
        guiext:portNotification [
            guiext:plugin <http://avwlv2.sourceforge.net/plugins/avw/scope> ;
            lv2:symbol "notify" ;
            guiext:notifyType atom:Float
        ] .


the Port definition in the plugin's turtle :
          ... [

                a lv2:OutputPort, atom:AtomPort ;


		atom:bufferType atom:Sequence ;
                atom:supports atom:Float ;   # <<<<<< NEED THIS (i think)


		lv2:index 1 ;
		lv2:symbol "notify" ;
		lv2:name "Notify" ;


              ] .


I also added more debug output to the GUI...  all relevant changes were committed in a git mirror on Github (its just easier for me to do that)  The only files I modified were  scope*.*  files

You'll want to look at the GUI code, because I also show you how to 'un-package' the atom in the port_event method.
