OBERKONN

via this auction
Click here and scroll for some prior posts featuring the OBERKONN including video.

Details:
"industrial VCF I call an OBERKONN. This is a very distinct vcf in which I focused on Sine Oscillation as it's main character.
Every input on the VCF has a big range. In otherwords you don't simply turn the knobs all the way up otherwise you will have crazy big big sound! This big sound only applies to Analog VCO signals. On Line level it will only bring it to Synth level, it will not push it as hard.You can either dial in clean or head into hard fat saturation (synth signals).
The Filter will self Resonate into a clean Sine Wave. As you go up the Sine Wave pushes harder and harder.

The panel is made of plexiglass and Actual Color is Yellow. The knobs are soft touch grey and green in color.
The jacks are switchcraft high quality 1/4 inch jacks.
The box is a blue Utility box, so the unit is lite weight. When you see it in person you think Lego.

THE FILTER IS NOT SEM OR CEM BASED. IT IS BASED ON DISCREET PARTS AND THE GOOD OLD LM13700. I LIKE THIS BETTER!


The filter is a 12db Variable state filter that offers LP, BP, HP outputs.
These are the features of the FILTER side:
-offers LP/BP/HP outputs
-has a bi-polar FM input
-has a normal cv attenuator
-has (2) audio inputs, there are (2) pre-amp trimmers inside the unit (i have them set to about 85%)
-has a Rez CV input with attenuator

The Audio inputs were intended for Analog VCO's. You can input Line level Sources but to achive the best Signal to noise ratio I recommend to use a Pre-amp to boost your signal. There are onboard
Pre-amps on the unit but they are not the cleanest or studio quality like your A&H mixer. Those onboard Preamps Fatten Analog Synth Signals(WAVE FOLDING!!), but on line level they only bring up the volume.
Out of the VCF's I have sold, this is a CLean sounding filter. Harsh is not it's main character.

Compared to the Steiner or LM4250 VCF, you can hear exactly when the Sine wave Whistle Begins."

"The signal is dry and demonstrates the Cutoff sweeps of the LPF/BPF/HPF.
An external Saw wave was used."

"This is a mixdown of the Pure Sine wave from the filter, an external Saw/Ramp wave, and an exernal midi to cv converter."

"Up for sale is an industrial VCF I call an OBERKONN. This is a very distinct vcf in which I focused on Sine Oscillation as it's main character. There is a switch to kick the vcf into hard big self oscillation.
Every input on the VCF has a big range. In otherwords you don't simply turn the knobs all the way up otherwise you will have crazy big big sound! You can either dial in clean or head into hard fat saturation.
In normal mode the Filter will begin Self oscillation at Mid level Knob location. As you go up the Sine Wave pushes harder and harder. If you like that smashed Sine wave sound you then can flip the switch to go even further.

The panel is made of 0.125" 6061 Aluminum. The panel is in frac rack standard measurements. The knobs are soft touch grey and yellow in color.
The jacks are switchcraft high quality 3.5mm jacks.
The unit is kinda heavy because of the wood.

I WIRED THE CV KNOB REVERSE, I ALREADY SHRINK TUBED IT SO I LEFT IT ALONE, THAT IS THE ONLY FLAW. SO IN OTHER WORDS THE CV KNOB FOR THE FILTER IS REVERSED (COUNTER CLOCKWISE). NO BIG DEAL.

THE FILTER IS NOT SEM OR CEM BASED. IT IS BASED ON DISCREET PARTS AND THE GOOD OLD LM13700. I LIKE THIS BETTER!

It has (2) Red VCA's that I was selling as a PCB also. The internal power supply is 15v based.
The power adapter is included in this auction. The box is made of pine wood and is very well constructed.

The filter is a 12db Variable state filter that offers LP, BP, HP outputs.
These are the features of the FILTER side:
-offers LP/BP/HP outputs
-has a bi-polar FM input
-has a normal cv attenuator
-has Linear FM input
-has (2) audio inputs, there are (2) pre-amp trimmers inside the unit (i have them set to half).
-has a Rez CV input with attenuator

EACH VCA offers:
-has a main volume out knob
-has an attenuated CV input
-has a direct CV input
-has an initializer knob like Arp VCA's"

Red VCO PCB Demo from BLCLONES on Vimeo.

"A midi to CV converter is used to play a Full Scale Sequence to show you the Excellent Tracking. First run is a SAW wave, then a Square Wave, next a Triangle wave, then (2) VCO's to show tracking, and finally a Linear FM patch between (2) red VCO's."

"HIS HAS SOME OF THE STUFF I HAVE BEEN SELLING LATELY:

HAS (2) RED VCO'S 1V/OCT BASED
-WAVES: RAMP, SAW, TRIANGLE, SQUARE
-(1)DIRECT LINEAR FM INPUT
-(1)DIRECT PITCH CV INPUT
-(1)ATTENUATED CV INPUT

HAS A SIMPLE MIDI-2-CV CONVERTER
-3 GATE OUTPUTS,
-3 PITCH CV OUTPUTS

HAS THE RECENT OBERKONN VCF COMBO UNIT
-12db FILTER WITH LP/BP/HP WITH BI-POLAR FM INPUT
-HAS A RED VCA WITH VOLUME OUT.
-HAS A NEW LFO WITH WAVES: RAMP, SIN, SQUARE, TRIANGLE.
-THE LFO HAS (2) SPEED'S SELECTED BY SWITCH

-HAS A TRIPLE ATTACK/RELEASE FRAC UNIT
-TRIG/GATE SWITCH
-QUICK ACTIVATE BUTTON (GREEN)"

ANALOG SYNTH 12X12 FULL MODULAR WITH MIDI CV

via this auction
"(1) TADPOLE VOICE PCB (VCO, AR GEN, VCA ALL ON (1) PCB)
(1)RED VCO (SAW,RAMP,TRI,SQUARE)
(2)VARIABLE SHAPE DUAL LFO'S
(1)MIDI CV CONVERTER WITH GLIDE
(1) MORE ATTACK/RELEASE GENERATOR (TOTAL OF 2 ON MODULAR)
(1)OBERKONN VCF WITH SINE WAVE AT FUL REZ.

BY DEFAULT THE TADPOLE WAVE OUT GOES DIRECT TO THE ONBOARD VCA, SO YOU WILL HEAR A BRIGHT UNFILTERED VCO WHEN YOU CONNECT FROM THE MAIN VOLUME OUT. JUST PATCH THE 'WAVE OUT' TO THE FILTER AND BACK INTO THE 'VCA IN' AND YOU WILL BREAK THE INTERNAL 'SWITCHJACK' WIRING I DID. IT'S LIKE A SEND/RETURN.

THE MIDI CV IS INTERNALLY WIRED UP SO YOU DON'T HAVE TO PATCH THAT. THE EXTRA SET OF PITCH/GATE OUTS ARE FOR EXTERNAL GEAR. THERE IS A SWITCH TO TURN OFF THE MIDI CV PITCH AND MAKE THE VCO FREE RUNNING TO MAKE NOISES AND NOT HAVE THEM TRACK."

"This is a modern machine I built for myself. It is what is called a drone Machine. But in this case it is more like an Extreme Sound Lab. It has 2 VCO's, (1) LFO, One Oberkonn VCF, and (1) Envelope Generator. There is a Volume out to control the big analog sound. I was influenced watching the Grendel Drone synths and figured I can build something with a little more power and features."
