VST3 Loads in Reaper/Steinberg editorhost but not Cubase (10.5)

Developer VST 3 SDK
1

Hi,
I am developing a new framework for making plugins.
With this I have made a prototype VST3 plugin, it loads OK into a few hosts, like Reaper and the Steinberg editorhost. It also passes the Steinberg validator 100% and the Traction plugin validator 100%. But it does not load in Cubase 10.5, it seems to be scanned and identified OK, but when I try to insert it as a send effect, nothing happens.

If anyone at Steinberg has the time to try this plugin and identify the problem I would really appreciate it.

You can get the Windows plugin here from github:

(“Artifacts” at bottom of page)

You can also get the source code if that helps:

Thanks!,
Jeff McClintock

Hi Jeff,

Hi Jeff,
I looked at your Gain example without UI and with this plugin you have implemented IComponent::getControllerClassId() and you return a UID that is not a class you export in your plugin factory.
And the other problem is, that Cubase doesn’t load plugin’s that don’t have an IEditController.

I hope this helps.
