Another point. Parameter changes are timestamped. (or we need a clear understanding of exactly when they affect the audio). VST is so vague about when a parameter change actually happens (at the start of the next block, or immediatly?, or when?). They arn't even sample-accurate. You can't even be sure what thread they happen in (user interface or audio).
