I remembered looking at the Rise and Fall gate outputs on After Later Audio Tilt and Joranalogue Contour 1 slewing modules and finding unexpected behaviors. Recently I remarked about this … Read More

Filling out my 4U Serge rack project is a Serge design based Dual Negative Slopes plus Hills and Valleys from Low-Gain Electronics. Of course the original Serge module names were … Read More

I’ve finished building the Slightly Nasty Model 2331 Asymmetric Slew Limiter. Here I’ll describe the build and show scope photos of the various operating modes. Features The ASL is another … Read More

I scored this very cool VC SLEW LIMIT/LOCK module from Hale for my 4U Serge project. The VC SLEW LIMIT/LOCK is a dual channel, dual mode module that can accurately … Read More

This post discusses scope trace pics of New Systems Instruments Inertia, in the Low rate mode. The Low rate mode is useful for envelopes, LFO, and slew limiting. Attack-Decay Envelope … Read More

My recent build of a Befaco Rampage prompted me to revisit several variations of the Serge Dual Universal Slope Generator that I have in Eurorack: Befaco Rampage, Random*Source DUSG, Steady … Read More

I built this Rampage from a kit. Notice the red and black Befaco jack nuts. The kit included a special tool for them, but I have a better one. One … Read More

The Serge Dual Universal Slope Generator is a legend in modular synthesis.  It is the basis of most voltage controlled slew modules, including Make Noise Maths.  I have built a … 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
