Four Point FM

Four Point FM

Four Point FM is a frequency modulation sound that uses 5 oscillators per voice, 4 modulators and 1 carrier. Each modulator is mapped to a quadrant point of the Continuum’s Y (front to back) and Z (pressure) space, such that a performer can play into each quadrant point by varying finger position from front to back and from minimum to maximum pressure.

Since each quadrant point has a different modulator oscillator with discrete frequencies and amplitudes, a wide variety of timbral morphing can occur. Four Point FM uses an aspect of FM synthesis technology that to date has been unexplored.
