Overview
2. Overview
The layout of Dark Energy II is that of a classic monophonic modular synthesizer. Its signal path is hard-
wired internally, thus Dark Energy II is very compact and easy to use. The most important modulation
routings can be set via toggle switches, additional sockets take or deliver control voltages and allow the
connection with external modulation sources. The internal MIDI/USB interface makes easy use within a
MIDI setup possible. Dark Energy II can also be used as a MIDI-to-CV/Gate interface. Wow!

saw 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
12 dB multimode VCF
- cutoff knob (freq.)
- tracking switch half / off / full
(internally connected to the VCO control
voltage)
- XFM: exponential frequency modulation
knob with positive and negative
modulation depth
- source switch selects modulation
source LFO2 / off / ADSR
- mode knob continously crossfades
between filter modes lowpass / notch /
highpass / bandpass
- resonance knob (up to selfoscillation,
depending on mode setting)
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
