random filter setting on keyboard press

[The girl next door]

Me personally....
I would open maybe 4 or more virus tracks (depending on how often your filter settings change) if each note has a different setting on each keypress/Note then assign note 1 to track 1,2 to track 2,3 to track 3,4 to track 4
and then start over again note 5 back to track 1...
If you have to many parts in your project open for this then bounce to audio.
we had this problem with VSTi?s in past projects as the Filter sweep was to quick and you could hear it going wwwwwwuuuuppppppp.and that isn't what you want is it !!!
Abit of advice,it gets quite complex so don?t have a beer while doing it
