keep checking... there is something that you have incorrectly set... nothing to do with the vst2 (if there was, you wouldn't be the only one with this issue)
- it may be something as simple as being sure the Input for 2A is set to None (instead of Host)
I have been using SAVIhost as the wrapper for a "standalone" of Helix Native vst without any issues in Windows10-64... it allows for a one-click launch of Helix Native.
Not sure why they wouldn't have had some kind of notice at their home page... as a new member, I have spent the last few days wondering what was going on, thinking it was at my end...
