The Sara VCF is a fully voltage controlled state variable filter with dual

“opposing” self oscillating cores. The tone capabilities can range from

delicate to outrageous and all stops in between. Everything from classic

vintage twin filter setups, oscillator into filter (quasi-lpg), self oscillation

and formant style soundscapes. The Sara VCF does well both in classic

duties and experimental sounds (just try self patching the state control

from one of the core outs).

With CV over every control the modulation possibilities open the palette of

sound even further.

Each core features:

 Control voltage for cutoff -12/+12v

Control voltage for Q 0/+5v

Control voltage for State 0/+5v (shared)

Self oscillation, tracking 1v/oct for around 4 octaves

Key features:

 Dual “opposing” cores where each core is a mirror state of the other

When one core’s state is swept fully low pass the other core is fully high

pass

Control voltage for state works well into audio range

Additional features:

 Eight simultaneous outputs from various stages of routing

Core two input is normalled from core one notch output

Can also be used as two independent filters

Each core has a different input/output response
