This filter module is a classic state variable filter. Compared to the wasp filter this filter has a significant self resonance and also a very quick response to cutoff frequency changes. For purchasing and other information please visit www.tangiblewaves.com/store/p61/SVFILTER_.html |

Can anyone provide any information on this filter?
What is it modeled on?
Is it a 2-pole filter I presume? The docs and wiki do not say.
I have a broken and old SV FILTER -- the CV knob barely has an effect -- and am purchasing a new one. But it'd be nice to see if there was some way to repair it.

When you say the CV knob has no effect, what CV are you feeding it (to CV1)? This is an attennuator on the CV input, so I wouldn't expect it to do anything without a CV source |

This is an attennuator on the CV input, so I wouldn't expect it to do anything without a CV source I really do appreciate the response but believe me, it doesn't work. If you set the CV1 knob to 100%, then feed in a big CV into CV1, say from an LFO, you get about 1/15 movement on the cutoff frequency if that. I have two Wasp filters to compare to, and they are radically better. CV2 is a little better but not by much. It could be a bad pot, but CV2 isn't amazing either. I'm guessing it's something else. [Here's hoping this broken behavior isn't *normal* for SV FILTER]. |

I get a good response from my SVFILTER… Apologies if my first reply came over as condescending, I am fresh from a work (my day job, not wonkystuff!) conversation where I thought the other person had tried the ‘obvious stuff’, but after 15 minutes it turns out they hadn’t!!! Good luck  |

I really like the SV filter. CV response is pretty moderate on mine, but it's perfect for smooth clean synth sounds.

I always assumed it was based on the oberheim sem, though if there's nothing written saying that perhaps I'm confusing with my old tinysizer? It doesn't sound like the sem, it's a fairly clean affair, though most 'classic state variables' are that way inclined. Interested to know myself now... |
