twinVCFilter

Two identical state-variable filters in 24 HP, each with lowpass, bandpass and highpass, a preamplifier with a clip lamp before it and resonance up to stable self-oscillation, from below 2 Hz to about 16 kHz.

Key features

• Two 12 dB/octave filters (6 dB/octave in bandpass), each with its own MODE switch
• GAIN drives the input from slight saturation to heavy overdrive, its red lamp marking the clip
• ROUTING: serial, dual or parallel; LINK sets both filters from section ●'s CUTOFF and RESO
• Two CV inputs per cutoff, one with an attenuator, and two for the MIX between the filters
• Outputs for each filter and a MIX output; the tVCF-Extension adds an output per mode and a notch
