Hello, Migrating to vst3 appears to be ok. Waves,softube,etc,all plugins from this companies are migrated by their vst3 versión and Works ok!.
But voxengo plugins ,glisseq...not.
I have both plugins installed (vst2 and vst3) and vst2 is not migrated..
What can i do?
Any workaround?
Thanks in advance!
 

It's dependent on the plug-in manufacturer including enough information (in the VST2 plug-in at that) to enable SONAR to know what the VST3 equivalent is.

The plugin vendor has to "advertise" that there is a compatible VST2 plugin via the VST3.
We will be publishing a far more general way to handle persist compatibility very soon. Overloud is already using this mechanism for TH2 -> TH3 migration.

Thanks Noel
 

I am having the same problem with Amplitube 4. I'm reinstalling everything from scratch on a clean install of Windows 10. Sonar sees Amplitube 4 VST3 and shows it in Plugin Manager but I can't access it to insert in a project. I thought it was a Windows 10 thing but it may be migration-related.
Keep us posted, Noel!
Thanks. :)
