No sound when loading Omnisphere VST

Hi,

When an instance of Omnisphere (2.6.4c) VST (not VST3) is created, it doesn’t produce any sound until either:

  • The instance GUI is opened
  • OR the instance setStateInformation is called with a valid state.

I’ve verified this behaviour with the AudioPluginHost (juce 6.1.6).

Is it required in the VST protocol to call setStateInformation on a new instantiated plug-in before it can produce sound?
