New Module: Farb Highpass - Analog Transistor Highpass Ladder Filter with Tilt EQ

video upload by Making Sound Machines

"Here's another neat little jam with a module from our brand new Farbfilter series!

This time introducing Farb Highpass - an #analog transistor ladder highpass filter, with a few tricks up its sleeve! It is a lovely sounding eastcoast subtractive synthesis filter topography that is often somehwhat overlooked and distinct from the classic lowpass ladder circuit.

We tweaked the #circuit and added CV controlled resonance to the feedback path. We also added a Tilt EQ. It lets you either bring some of the warmth back in, or double down on the #highpass effect and go all sizzly.

In this patch, we're using Stolperbeats to sequence the @WeAreElektron modelcycles, its audio processed through the left #FarbHighpass. The module receives resonance CV from Stolperbeats' envelope out, generating a pulse whenever the kick drum is playing. You can hear the filter's lovely self-resonance kick in with the sweep at the start of the video.

The bass is a Sharktooth wave from @apolloview9305 awesome #Allscillator complex VCO (kits available from Thonk). Its output is folded using the right hand Farb Highpass, with Stolperbeats sending a CV ramp to the filter cutoff with every bass drum. With CV patched, the cutoff knob becomes an offset for the incoming voltage.

At the drop, the voltage controlled resonance is expertly wobbled using @Befacosynth Rampage, good news! We have a small batch of DIY kits packed - you can solder the DIY version with our lead #engineer Enrica and be the first to get your hands on one of these modules! If you can't make it, the kits will become available after Superbooth via our friends at @ThonkSynthDIY and @explodingshed5542 .
