SVF

This is a traditional analog State Variable Filter (SVF) implementation that incorporates Vactrols.

Functionality#

• Ideal for creating ACID and LEAD sounds
• Features resonance control
• Simultaneously provides LOWPASS, HIGHPASS, and BANDPASS outputs
• CUTOFF frequency control via CV input
• Supports GATE signals as CV input thanks to Vactrol integration

Inputs#

1. Audio In
2. CV IN
3. MULT
4. MULT
5. MULT

Outputs#

1. LOWPASS
2. LOWPASS
3. HIGHPASS
4. HIGHPASS
5. BANDPASS

Controls#

• RESONANCE: Adjusts the filter's resonance level
• FREQ: Sets the CUTOFF frequency of the filter (CV input is limited to this maximum value)
• FREQ CURV: Reduces the filter's frequency range for more precise control (turn clockwise to decrease range)
