If you really want 'sample accurate' control for bandlimited 
controls then the host must provide future values. Which is not
more difficult than providing latency compensation for audio
signals, at least not if the control rate is fixed. It's not
at all an issue for the plugin code and you certainly don't
need two versions of it.

and hysterically inflated market opportunities. (Cory Doctorow)
