Overview

2. Overiew

Dark Energy‘s architecture ties up with a classic monophonic modular synthesizer. It‘s signal paths are 

wired internally, thus Dark Energy is very compact and easy to use. The most importand modulation paths 

can be set via toggle switches, additional sockets deliver control voltages and allow the connection of

 

external modulation sources. The internal MIDI/USB interface allows the easy use within a MIDI setup. 

Dark Energy can also be used as a MIDI to CV/Gate interface.

triangle waveform based VCO 

- tuning knob

- range switch -1 / 0 / +1 octave 

- FM (frequency modulation) knob with selectable

  modulationsource  (LFO1 / off / ADSR) 

- pulswidth knob for squarewave

- PWM (pulswidth modulation) knob with selectable

  modulationsource  (LFO1 / off / ADSR)

- waveform switch (saw / off / triangle)

The sum of the squarewave signal and the waveform 

selected with the waveform switch is fed into the audio 

in of the filter module (to disable the squarewave both 

PW- and PWM-knobs have to be turned fully counter-

clockwise).

VCO CV inputs

- VCO frequency (1V/octave)

- pulswidth of squarewave

24 dB lowpass VCF

- cutoff knob (freq.) 

- tracking switch half / off / full

  (internally connected to the VCO control

  voltage)

- XM: exponential frequency modulation

  knob with selectable modulationsource

  (LFO1 / off / ADSR)

- LM: linear frequency modulation knob;

  modulationsource is the VCO‘s

  trianglewave (resp. the VCF gets linear

  FM from the VCO with adjustable

  intensity)

- resonance knob (up to selfoscillation) 

audio input

(the connected signal is 

mixed into the VCF input) 

VCF CV input

- VCF frequency (1V/octave)

VCA

- amplitude knob 

- AM (amplitude modulation) knob

  with selectable modulationsource 

  (LFO1 / off / ADSR) 

VCA CV input

- VCA amplitude

LFO1 and LFO2

- frequency knobs

- waveform switches (triangle / off /

  square) 

- range switches: low (up to several

  minutes per cycle) / audio (up to

  5 kHz) / medium (normal LFO range

  from some seconds up to several

  10th hertz)

- dual LEDs yellow/red show positive

  and negative halfs of the LFO waves

LFO1 CV output

(inverted)

ADSR

- knobs for Attack,

  Decay, Sustain and

  Release 

- range switch long / short /

  medium 

- blue LED for envelope

  activity
