APIs & Application Integration

Hi, I’m looking to create a closer integration with Cubase and Nuendo for a 3rd party application.
Nothing particularly complex just an ability to send an audio file to a new track in an open project kind of thing.
Are there APIs exposed for this kind of task? I’ve been looking at the VST3 vst3_pluginterfaces repo but it doesn’t seem containing anything that suggests this API is available via the VST3 SDK.

Any pointers would be really appreciated. Thanks.

The VST3 SDK does not provide this functionality. The VST API is solely for processing audio either in realtime or offline, project or track management is not part of it.

Thanks for confirming my suspicions.
Are there any other ways this could be achieved?

Ahhhhhh, I’ve just discovered this the SKI Remote tools.
