GMU:Performance Platform Introduction/Etienne Colin: Difference between revisions

I thus established that the Root position (x coordinate) in the space will control the carrier frequency of a ring modulation, and that the Head position (x coordinate) in the space will control the center frequency of a notch filter. In that way, when the listener moves on the platform, frequency modulation and a sweep effect will result.

Besides,

The elevation of the left arm (y coordinate) controls the speed of a metronome that generates a fixed frequency subjected to an envelope generator.  The elevation of the right arm (y coordinate) controls the feedback of a delay applied to the same source. When the arm is down, there is no delay (feedback=0) when the arm is raised to the maximum the feedback goes up to 0.7. The association of interactions with both arms was supposed to have a really playful effect on the listener who literally controls the "instrument" like a conductor.
