Thanks for your interest, sorry for not being clear... Here is a condensed version of the idea:
A new Effect to put in the chain, that would have one Param: Sensitivity, and an editable list of assignments.
It would sense (= measure, as a "Sensor" ;-) the signal passing through it, and control any Param from any other Model/Effect in the chain, from the measured value...
Example signal chain: IN---[Sensor (Sensivity = 50%, assigned to "Phaser / Phase" and "Drive / Gain")]---[Phaser]---[Drive]---OUT.
It would make the Phaser effect, and the Drive Gain, "respond" to the intensity of the playing.
