See this important circuit update for a fix to the noise floor. Befaco A*B+C is a dual four-quadrant multiplier with VC offset, a Eurorack utility module with a distinctive design. … Read More

This diagram shows a generic quantussy cell, as I call it. See What Is The Quantussy for more information. It’s the name of the five oscillator cluster in Peter Blasser’s … Read More

Peter Blasser’s Sidrassi circuit was the first incarnation of an evolution of his design for a seven-oscillator organ.  Others have told the story well. Fans of the Sidrassi/Sidrazzi/Sidrax have never … Read More

I am nuts about voltage-controlled slewing modules, which all stem from the Serge Positive and Negative Slews, and the Dual Universal Slope Generator (DUSG).  In Eurorack I have Make Noise … Read More

Improvised with modules arranged in new rack.  Yes, it’s Clouds into Rings! Mostly Mutable Instruments, but with a delay from Black Hole DSP.  

In my previous post I mentioned a case idea for the Swoop Spokes PC board. I made it of two pieces of 1/8 inch clear acrylic, which were cut to … Read More

The paper circuit, shown above, is the only information that we have that pertains to the Swoop Spokes.  It was a kind of mystery circuit that no one else (that … Read More

Here’s the result of a light bulb going off in my mind a few days ago.  I have several different cases for Eurorack modules, and I’ve found that patching across … Read More

L-1 Stereo VC Mixer replaces the Verbos Scan & Pan for my output mixer. Features 4 stereo channels with voltage controlled level and panning Voltage controlled sum out level Stereo … Read More

Ever since that time, in 2012, that I was captivated by the Ciat-Lonbarde Cocoquantus oscillator cluster, which Peter Blasser called the Quantussy, a Nabra or analog brain, I have sought … Read More
