I am trying to create a patch for a project that will gradually change the EQ of a live signal over time. Is there a way to automate the [filtergraph~] object (perhaps with the [line~] object?) to go to specific values at specific times? Basically, I would like to do what is possible when you click on the filter graph itself and change the filter with the mouse, except I would like to program this activity to happen on its own without using the mouse.

as you mentioned the [line~] object, you're no doubt aware that this object will respond to multiple 'target/time' pairs, for example [0., $1 $2 $3 $4 $5 $6] start at 0 go to $1 in $2 etc, much like the [function] object which might also apply here; and of course, you can use any signal/function generator for custom ramps: cycle~, rand~, trapezoid~ etc etc - but for real detail on LFO automation, look at Gregory Taylor's extensive but accessible tutorial:

Have you considered [filtercoeff~]? It is not graphical, but it can be controlled by any kind of automation signals.

Sorry I haven't responded --- Thanks for the advice! I got the patch to work with [line~] after all. Thanks for telling me about Gregory Taylor's tutorial!

use autopattr and pattr storage to drive tendency masks in the controlling of the filters

automated [filtergraph~] ?
