[filtergraph~] edit spots?...

howdy y'all,

been a while since i messaged on here that was related to maxing, so here goes.

i am messing with [filtergraph~] and i love the thing, i think it is great, especially with [cascade~].
but one thing i was wondering about are some editing spots i could put at the ends of each [filtergraph~] point. very much like the filters you see on daw software, where you can grab the points of different filters and move them around. instead of grabbing the filter and then expanding them etc.

if this does not make any sense. if you look on say, the ableton 'eight eq'. i would like to implement something like that to the [filtergraph~].
i have tried using function and working something out bit by bit, but can not figure it out. maybe it is all this maxing has me boggled, but i am sure i have seen something like this a while ago.
its either that or all this crack smoking is clouding my thoughts. but it does keep the evil monkey off my back for a few hours :)

that is what is on the plate. the patch idea, not the crack :)...
