Random*Source Serge Dual Universal Slope Generator Mk2 (DSG)

¥72,900 (Tax excluded ¥ 66,273)
Serge's original "army knife" module, which is also a powerful oscillator!

Format: Eurorack
Width: 26HP
Depth: 40mm
Current: 90mA @ + 12V, 80mA @ -12V, 0mA @ + 5V

* A range switch has been added since 2021. (Image is being prepared)

To protect the original signal voltage range of Serge, the signal handled by Random * Source Serge is smaller than the standard Eurorack module, which is 5V at Peak to Peak.It is not as small as the line level, but when using it with other companies' products, pass it through a signal booster or attenuator as needed.


The Serge Dual Universal Slope Generator (DSG) is the most versatile module in the Serge system that can provide a wide range of functions for both CV and audio.Many Eurorack function generators are affected by this module.

The functions of the two slope generators that make up the DSG are as follows.Although it plays various roles by patching, R * S DSG has Rise and Fall time.0.1 ms or lessBecause it reaches the high frequency of 10kHz or more in terms of frequencyAudio rateBut it works great.

  • When a signal is input to "IN", the change in input voltage is delayed at the speed specified by Rise when the input voltage rises and at the speed specified by Fall when the input voltage falls (lag processor, slew). With this function, if you enter the pitch CVPortamentoIf you enter the gate, 100% sustainASR envelope, If you input the soundEnvelope follower,Low resolution filterCan be used as
  • When a gate or trigger signal is input to "TRIG IN", the voltage movement that rises at the time specified by Rise and falls at the time specified by Fall is triggered once. With this function,AD envelopeCan be used as
  • When Cycle is turned on, a voltage that rises during Rise time and falls during Fall time is output repeatedly, and becomes the oscillator. With this function, if Rise or Fall time is short,VCOAnd if longLFOCan be used as

Furthermore, if you use the "END" output that is output as a signal of the end of Fall, the trigger input to Trig In will be output after being delayed by the time of Rise and Fall,Trigger delayWill be. Also, when the AD envelope is rising, it is not retriggered by the signal to Trig In, so input the clock to Trig In and set the Rise and Fall times longer than the clock time interval.Clock dividerWill be. For the same reason, if you input a pulse wave to Trig In, you can output subharmonics such as integer octaves lower (Subharmonic generator).
Especially in DSG mk2, the function as audio has been enhanced.Tracking about 4 octavesIs possible.
