Thanks Peter,
Since the latest update 607, the Plugin does now show up in Sonar/Cakewalk plugin manager as a VST3i which it did not before the current patch.
You say you have it working in Cakewalk/Bandlab 2018.11 build 25
This does not help me since I have a fully functioning Sonar X3 Producer (X3e Build 352) - x64 running Win 7 Professional
Have you actually tested it on Sonar X3 Producer?
Perhaps you could suggest what settings I might need to make to run this plugin successfully?
