Koma Elektronik SVF201

State variable multi-mode filter with optical components (vactrols) that provide for a good sound. Three filter types are available and you can blend between them. Voltage control of cutoff, resonance and mix.
The filter has a slope of -12dB/octave and three filter types: low pass, band pass and high pass, available at individual outputs. Besides this you´ll find the Mix parameter that will blend between the filter types manually and by voltages and send the result to the according Mix output. The Mix Out attenuator acts as a normalized CV source if nothing is patched into the Select CV input
The resonance can be voltage controlled as well.
Soundwise the filter is pretty nice as it has a very unique sound, somehow nasal and metallic; very interesting!
the cutoff controls is backlit with a white LED, this can be deactivated by a jumper on the back.
4 Audio outputs: low pass, band pass, high pass, mix
3 CV inputs for cutoff, resonance and mix.
