This is a PCB/Panel set in the Eurorack format.

Availability: In stock




From Yves Usson/YuSynth:

This is my latest take at the Steiner-Parker VCF, in which I tried to improve the design in order to correct some flaws of the original design : scratchy resonance potentiometer, untamed auto-oscillation.

From Timo Rozendal:

Changes from original design: 
- no switch but separate buffered input for every mode (LP,HP,BP), 
- lowpass input is normalled to highpass and bandpass, so you can e.g. transition smoothly between high and lowpass with the knobs 
- 'tweak' resistors are replaced by trimpots 
- added decoupling capacitors for ic's 
- added a flexible footprint for the matched transistors, I tested it with THAT300, AS394 (Letvian LM394 clone), 2n3904 and BC547 (I don't hink the original 2SC1583 will fit) 
- provided panel pcb, so no wiring required 

The inputs have enough gain to overdrive a normal signal in the filter. 
The resonance is still a bit untamed and chaotic and not so useful for melodies (plus it won't self resonate at low frequencies, a known trait of this filtertype)

Blown away!Review by Gregor
I was extremely pleasantly surprised by this badass filter! I always mess with the MatrixBrute when visiting Guitar Center for something and IMHO this sounds as good or better than the MB’s Steiner. Highly recommended! (Posted on 6/17/2018)
