HostPluginDemo does not produce sound?

I am trying to load the Dexed synthesizer plugin into HostPluginDemo. It can be loaded, but it does not produce any sound?

The HostPluginDemo is a bit “curious”, it doesn’t actually implement processing the sound at all. I guess that is because of the complexities that arise from the ability to change the hosted plugin on the fly, which could have made the example more complicated than what they wanted to deal with.

Isn’t the point of the examples to show how something is done? What good is an example that doesn’t work…

As you can see, there’s already a lot of code needed to just load the plugin and show its GUI, the example shows how to do that. But it’s indeed odd they didn’t make any effort to implement the actual audio processing in that.
