The Sallen-Key VCF pcb is a classic Multi-Mode (LP/HP) voltage controlled filter design, commonly found in synths like the MS-20. Agressive, Gnarly, and a must have in your Modular System.
1.Cutoff – This sets the cutoff frequency of the filter.
2.Cutoff CV – This attenuates the voltage from the control voltage input.
3.Resonance – This controls how much of the filters output is fed back to it's input. At maximum the filter will oscillate without an input.
1.LP IN – Signal inputted here will be low-passed through the filter. DC coupled.
2.HP IN – Signal inputted here will be high-passed through the filter. AC coupled. Both inputs can be used simultaneously.
3.CV IN – Control voltage for cutoff frequency.
4.OUT – Signal output for both Low pass and High pass modes.
