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
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 slightly different input/output response
