About This Listing

SEMSVF Noir Edition is a black panel version of my Eurorack adaptation Oberheim SEM State Variable Filter in 12HP.  The module is identical to my white panel Tribute edition apart from the color of the front panel. Each module being meticulously handmade in limited quantities, with a sound to die for and a look paying homage to an icon. 

SEMSVF is the king of 3080 OTA  filter designs.  A characteristic resonance feedback circuit and accept-no-substitutes obsolete NOS FETS at each stage yields an absolute creamy and silky filter response.  LP/HP and BP outputs.  A pair of signal inputs with mix pots.  That frequency MOD input with signal inverting.  That LP/HP/Notch mix sweep control that is CV modulated!  You’re welcome. 

FREQUENCY | the initial Cutoff Frequency of the filter

RESONANCE | the depth of the peak frequency resonant feedback.Res will not self-oscillate without an input signal present.

IN#1 & IN#2 | Mix together 2 different audio signals, each w/ their own mix pot.

MOD | Modulate the Cutoff Frequency w/ any polar/bi-polar signal.  At 12 o’clock, the pot has no modulation.  In the Counter-Clockwise direction it can invert the incoming control signal.

KB | Modulate the Cutoff Frequency w/ a V/oct signal or any other polar/bi-polar mod.  Self-oscillation resonance will track v/oct when KB is set to 100%.

NOTCH | Sweep the response from Lowpass, through Notch, to Highpass on the LP|HP Output.

LP|HP CV | Use external modulation to control the mix of the LP|HP|Notch.  The LP|HP CV knob amount is summed with the NOTCH knob (initial mix setting) above it.

LP|HP OUT | the audio output jack of the LP|HP|Notch filter tap.

BP OUT | the audio output jack of the BP filter tap.


Includes a 10-pin to 16-pin Eurorack ribbon connector. M2.5 or M3 (Doepfer standard) Phillips-head basic zinc rack screws are only provided on special request. Why do I do this? To cut down on rack screws that are wasted in the universe. You're welcome :D
