Synthrotek Drum Synth Module: DS-M Time Lapse Build

Play Video

We take on the Synthrotek Drum Synth Module otherwise known as the DS-M in our latest Eurorack Modular Build. The DS-M is a full featured drum synth that can emulate virtually any drum sound with a twist of a few knobs.  It is a complex, modifiable analog drum synth loosely based on the Coron DS-8 according to the Synthrotek website.  It a relatively moderate build with stand up resistors and intricate soldering points needed.  We recommend if you are new to soldering, to start out with something other then this.  

During our build, we made sure to double check each resistor prior to populating the board.  As usual, diodes and caps are directional based whereas the resistors are not.  This 8hp module packs a big punch just like its predecessor the DS-8.  Changes to the original DS-8 include the following:

  • VCA-like trigger input (more voltage = louder output)
  • Trimmer-adjustable attack
  • LED trigger indicator
  • 1v/o tracking (C0-C4)
  • Triangle core oscillator
  • Additional noise color switch setting (3 settings instead of 2)
  • More distinct noise timbres
  • Louder, improved noise circuit
  • Really LOW bass frequencies 
  • Total range ~4Hz to 2.6kHz

As well as being an amazing little drum synth, this module is also a fully functional monophonic synth that has the following features:

  • 1v/o tracking (C0-C4) 
  • Adjustable attack and decay envelope over the VCA 
  • Built-in LFO circuit
  • Sweep circuit
  • Noise circuit

You can plug in your CV or keyboard directly from your MIDI-2-CV converter and you are ready to go!  You can also use it stand alone as a monophonic synth if you choose to do so.  

DS-M Features:

  • Width: 8hp
  • Depth: 1.75″ (44mm)
  • Power connection: 10 Pin Keyed Eurorack
  • Current Draw: +12V: 20mA, -12V: 10mA (5V not used)

Hint:  The magic really happens when you connect 2x DS-M’s together….
