I want to have an external process handle some of the processing for a VST. Is there some way to inform hosts that my plugin processes data asynchronously and then inform the host when it has been done?
I found wantAsyncOperation() function from VST2 SDK that can solve this issuer. But it was deprecated in VST 2.4.
No, there is no such feature in VST3… a way to do it is to use a ring buffer, with a latency reported to the host, it should be possible to handle such use case… This is done by plugin sending and receiving audio through ethernet…
