Dark EnerGy DOEPFER 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
