Hi Michael

Sorry for the late response and thank you for feedback.  I've updated
lvtk to use  -Wl,-z,nodelete in Git.

What git are you referring to? I pulled git://lvtoolkit.org/lvtk but cannot see the changes there.
 
I haven't had a change to try avw.lv2 quite yet.  Is this a synth plugin
by chance?  If so, I'll add some other changes to lvtk that are floating
around...

I recently discovered the Synth wrapper isn't exactly frame-accurate
when triggering MIDI note-on/off events.  Good thing is I know exactly
why and where to resolve it.  I should have a chance to roll those in
later this afternoon.
 

the avw.lv2 plugins are not exactly synths, they are modules to create synths in Ingen.
I ported them from the internal modules of AlsaModularSynth.

So they don't use MIDI but Control Voltage ports - and now Atom ports thanks to your work and David's :)
