eowave Domino Synthvoice


The Domino is a discrete analog monophonic synthesizer with a VCO in the tradition of the MS20 and TB303. VCO, filter and VCA are transistor based, and the filter is a 24db low-pass resonant filter. Transistor based architecture gives the Domino a unique sound, simultaneously raw and rich.

  • Saw/Square wave VCO
  • Low-pass filter
  • Decay envelope
  • Switchable gate/envelope to VCA
  • 2 external audio inputs
Functions: Oscillator , Synth Voice , VCA
Height: 3U
Width: 10hp

The Domino is a redesign of its desktop synth bigger brother. Packing a full-featured synthesizer voice into 10HP, the Domino includes a saw/square wave oscillator, ladder type low pass filter, decay envelope and VCA. A plethora of patching possibilities makes this module a keen choice for portable systems, and those looking for deep sonic crafting within a tight HP space. Pair with a sequencer for instant basslines and acid lead lines, add some modulation to unlock the full sound design potential

Using the pitch knob, the tuning range is 1 octave, designed to be used primarily in lower ranges. Middle position of the pitch knob is 110khz (A2) after calibration - this can be adjusted at home using the vco_tune trimmer
