# Scoofster SV Filter v0.9 ## What is it? It is a filter based on state variable filter code. The outputs are tweaked, so you have different working modes. ## Features: Stereo processing Adjustable frequency range Self-oscillation! Rare modes like resonant 6dB/Oct lowpass/highpass Different samplerates are supported Inertia control Reset command in case the filter blows up ## Parameters
| Cutoff | Controls the cutoff frequency of the filter. Default range is 20 Hz - 22050 Hz.
| Resonance | Controls the emphasis at the cutoff frequency. Warning: 100%=self oscillation.
| Type | Selects filter type:
LP6 |  | Resonant 6dB/Oct lowpass
LP12 |  | Resonant 12dB/Oct lowpass
BP |  | Bandpass
HP6 |  | Resonant 6dB/Oct highpass
HP12 |  | Resonant 12dB/Oct highpass
Notch |  | Notch
Peak1 |  | Peak
Peak2 |  | Peak (narrower bandwidth)
Peak+Notch1 |  | Something like resonant lowshelf
Peak+Notch2 |  | Something like resonant highshelf (sounds good on saw wave)
| Inertia | Controls the time the filter responds to cutoff changes.
## Attributes
| High quality | Selects whether the filter is double sampled or not. I suggest using only High quality mode. (You can save CPU by turning it off, but the filter won't be accurate at high frequencies).
| Resolution | Controls how often the filter is updated (in samples). For fast modulation, set it to 5-10. For economy, use larger values (20-40).
| Freq min (Hz) | Selects the lower frequency limit.
| Freq max (Hz) | Selects the upper frequency limit.
