automation in VST is quite simple, when you want your UI tweak to be automated by the host, you just send a command. I see no headache here.

You're not gonna let the host automate every single message the plugin needs to send to its processing anyway, most won't even be automatable things.


yes you can. The simple fact that the UI & processing are in separated *threads* means that a dual CPU system will spread both CPU's on timeslices of both threads at the same time. Under windows that is.

I think that you are missing another very very important aspect of having the GUI communicate with the DSP through the host. It gives the host the ability to record the entire communication between the GUI and the DSP, with the opportunity to then display that in some sort of editable form for the user. The fact that a lot of VST plugins GUI-DSP links are completely invisible to the host means that the automation capabilities of VST plugins are all over the map, and a major headache for host developers.
