It features two discrete voltage-controlled oscillators (plus sub-oscillator) per voice with continuously variable waveshapes (sawtooth and variable-width pulse, plus a triangle wave on oscillator 2). The classic Oberheim-inspired 2-pole, state-variable, resonant filter provides low-pass, high-pass, band-pass, and notch functionality. Voltage-controlled amplifiers complete the all-analog signal path.\u003c\/p\u003e\t\t\n\t\t\t\t\t\u003ch1\u003eDual Effects\u003c\/h1\u003e\t\t\t\t\n\t\t\u003cp\u003eThe dual effects section provides studio-quality reverbs, delays (standard and BBD), chorus, flangers, and faithful recreations of Tom's original phase shifter and ring modulator.
