Voltage Controlled State Variable Filter Cinnamon is a unique sounding filter. The presence of drive and character switches makes it a multi-flavored spice for your sound! Voltage Controlled Cutoff and Character Switches to Spice Up Your Sound!Combining the input volume with the character switches affects the output sound drastically. Features voltage-controlled cutoff frequency CV input with attenuator volt per octave CV input audio input with gain control drive switch to overdrive the input of the filter low pass output (12db/oct – 2-pole) bandpass output (6db/oct – 1-pole) high pass output (12db/oct – 2-pole) resonance control character switches to change the resonance response (character switches might break V/Oct tracking) with maxed resonance works as an oscillator (0°, 90°, and 180° phased sinewave at LP, BP, and HP outputs) character switches change the waveform when self-oscillating and might also break the V/Oct tracking front panel from aluminium or oak wood with custom knobs handmade locally by Bastl Instruments in Brno, Czech Republic
