Hello Hermann,
  In the mean time some work have been done on this. A
couple of bugs been
 ironed out, and a couple of features been implemented. Also a pre-build
 x86-64 linux binary package, ready to copy over to ~/.vst3 is provided
 on the project page.
 Since Ardour have updated there tool chain (7.3) it also works flawless
 in Ardour.
 In case you haven't checked it out already, now is a good time to do so.
 In case you've some time ago, it's a good time to update.
 
Got around trying out the plugin. Looks good! How to load your own
presets though? I now edited dirlist.js but that's probably not the
right way I guess. And got Ardour 7.3 to crash a couple of times when
selecting presets :(
