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
