Variable Character Ladder Filter enhanced from the Moog ladder filter from the original E-mu Systems 2100 LPF module

• A Genus control that allows continuous voltage control of the number of filter poles (from 3 to 6 poles), essentially allowing real-time variation of Evolution’s effective cutoff slope from 18dB/oct to 36dB/oct. LEDs give continuous indication of the current slope.
• A Species control that lets you vary the signal level into the ladder, letting you control the intensity of the filter’s characteristic distortion. When in self-oscillation mode, this control modulates the amplitude of Evolution’s output.
• Voltage controlled resonance with a variable Q Level Compensation control that controls the balance of the resonant peak and the frequencies below the cutoff frequency (which would otherwise be attenuated as the resonance is increased).
• An extremely accurate and temperature-stable frequency control exponential generator (accurate over 10 octaves), rivaling the specifications of the best analog VCOs.
