Dual Opposing Core SVF
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
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
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 slightly different input/output response
