DUSG3It contains all components required for a complete build, right down to rack screws and power cable. We selected and used the high quality parts as specced by Random*Source.

Most of the components are already soldered! The back board is already fully populated and soldered with SMD components, this is therefore a very quick build that mainly requires soldering of pots, jacks, trimmers, LEDs and headers.

SERGE MODULAR FOR EURORACK – Under licence from Serge Tcherepnin

“Serge Modular” is an analogue modular synthesizer system developed by French composer and electronic designer Serge Tcherepnin in the 1970s at The California Institute of the Arts. Serge’s vision to create a “people’s synthesizers” led to a unique modular music system with an iconic design.

In collaboration with and under licence from Serge Tcherepnin, Random*Source offers a range of Serge modules, combining the original Serge circuits with the advantages of today’s technology. The modules on this page are in Eurorack (3U) format – modules in the classic Serge dimension (“4U” panel height) and the typical banana jacks can be found here.


DUSG4The Serge Dual Universal Slope Generator (DSG) is probably the most versatile module of a Serge Modular system, incorporating a wide range of functions for both CV and audio. Some functions for which one Slope Generator can be used: VC Transient Envelope Generator, VC LFO, VC Portamento device, Envelope Follower (Detector), VC Pulse Delay (Monostable), Sub-Harmonic Series Generator (Divider), Audio Oscillator with variable waveform symmetry (saw to triangle), Non-Linear Audio Processor (low-fidelity VCF).

From the catalog: “The Universal Slope Generators are unity gain voltage followers with voltage controllable slopes. The range of control is exponential, extremely wide, and the Rise and Fall times can be controlled independently. The range of the Slope Generator is from sub-sonic to high audio frequency. Trigger inputs and trigger outputs allows each section of this dual module to function as a transient (envelope) generator, pulse delay, or in a “cycling mode” (to produce an LFO or clock). Since the Rise and Fall times are voltage controllable, this adds another dimension to the above functions.

The DSG mk2 version has been optimized for audio performance and speed/precision. The top section covers a frequency range up to more than 10kHz. It also offers improved tracking and some temperature compensation.

Now – for the first time and licenced by Serge – the DSG is available as an updated (mk2) version kit for Euro.

Some details of the Random*Source Serge DSG kit:

  • Under licence from and in cooperation with Serge Tcherepnin
  • Separate VC inputs for Rise and Fall
  • improved tracking (up to 4 octaves)
  • Pulse out with 50% duty cycle in the top
  • Uses selected audiophile parts for superior audio performance (up to >10kHz)
  • DSG mk2 board in SMT, manufactured in Germany
  • No wiring needed
  • Eurorack format (3U), 26 hp
  • Power consumption: 90mA @ +12V, 80mA @ -12V
  • Module depth: < 40mm (1.5″)
