Doepfer A-122 24dB Low Pass 2

Doepfer A-122 24dB Low Pass 2 filter module is based on the Curtis chip, which was also used in the game-changing Oberheim synthesizers. Thanks to the plenty of FM (and resonance CV!) inputs, you can achieve really complex FM (frequency modulation) with it too. Beware: this filter cuts like a surgeon knife.

Doepfer A-122 24dB Low Pass 2 is a voltage-controlled low-pass filter, which filters out the higher parts of the sound spectrum, and lets lower frequencies pass through. The cut-off frequency determines the point at which filtering takes effect. You can control this manually, or by voltage control (filter modulation, for instance by an LFO). Two CV inputs are available. The cut-off slope is -24 dB/octave. The circuitry uses a Curtis chip, and is very similar to the classic Oberheim filter sound. Because of its different circuitry and controls, the A-122 has a considerably different sound to the A-120 'Moog-like' filter, especially in the way the resonance behaves. Voltage controlled resonance: on the A-122, resonance can be controlled not just manually, but by voltages as well, right up to self-oscillation. In this case, the filter behaves like a sine wave oscillator.
