The strong action of devices for sound transformation and abstract-shaping occurs when these devices impose too much of their own characteristic effects, sometimes fooling composers into believing that the result obtained is due to characteristics belonging to the input sound or his or her imagination. The same can be said when an exaggerated use of devices marks sounds or events with a presence that overwhelms the sounds (and events) themselves.
Even though acknowledging the difficulty of the terrain, I believe that there is something political in the strong action of devices. Strong action is not only responsible for imposing on musics the language of the device, but also, by supporting a musicality based on the device's power. (Source - Rodolfo Caesar (1992).
