my plug-in’s need to store per-instance state such as UI settings etc.
In the VST3 version I use
when the state changes to notify the host a save prompt should be displayed (* appended to project filename). This works fine in conforming hosts.
However in VST2 I cannot seem to find anything similar. I’ve tried
as a workaround but that doesn’t work.
Is there any solution / hack I might employ ?
I could add a dummy parameter to notify the host, but that seems like a messy way to do it, also potentially confusing to users.
