Intellijel has made the already awesome Thru Zero VCO Rubicon even better! In addition to the seven waveforms plus sub-oscillator of the first version, the second generation offers a new Warp stage, which generates a hybrid of complex pulse and other waves. – You can even use external audio material. In order to keep results in the range of 10 Vpp, there is a wave folder called Squish. On top, the FM capabilities were expanded.
