Electronic music vividly illustrates other worlds in a process of discovery, re-interpretation and expression: energy, technology and imagination at the helm.

XaVCF Eurorack OB-Xa Filter Adaptation Now Available
The XaVCF is a faithful adaptation of the OB-Xa filter in Eurorack with added features. As with the original, the XaVCF has two filter circuits to choose from! The heart of both designs having each its own Alfa reissue AS3320 chip. The XaVCF has the original Modes: a 4-Pole standard Lowpass circuit, and a 2-Pole Lowpass derived from a State-Variable circuit. Additionally there are 1-Pole Bandpass and Lowpass modes not available on the original!
Caution! Aggressive resonant peaks ahead, watch your levels.

XaVCF Test Filter Circuit [Audio Only Demo]
I've been getting requests for demos of my upcoming XaVCF module.
It will be a eurorack adaptation of the OB-Xa filter.
More info at Modular Grid
You know this sound from Rush Tom Sawyer and Van Halen's album 1984.
While we're all eagerly awaiting the module prototype I thought
I would share a brief sampling from a mini-lab test circuit.
A more thorough overview of the module will happen when it gets built.
So be on the lookout for that one in the near future.
The XaVCF will sound pretty far out.
We're talking about full on intergalactic blast off here.
Headphones recommended. BUT!...
Watch your levels, thick resonant sweeps ahead!
Prepare for ignition...
