These unpredictable core oscillators are related to each other and their charge and discharge cycle creates complex rhythmic sound textures that can be controlled and triggered with external CV inputs to add more contamination.
With this circuit we can obtain rhythmic textures- intended as rise pulses – and different tone heights by mixing the colors of the LEDs and the values of the capacitors. The waveform of a single oscillator, unfiltered, is basically a sawtooth. The result of the FM modulation of the whole sound engine is chaotic.
