Doepfer Quadrature Thru Zero Voltage Controlled Oscillators with double frequency modulation

A demonstration of cross frequency modulation with Doepfer modules A110_4 and A110_6. Each oscillator receives the other's sine wave as LFM modulation input signal. It results in the creation of a rich variety of new timbres. It can get really wild and noisy. If only you appreciate it, or maybe learn to appreciate it.
