DARK ENERGY II
Monophic Analog Synthesizer
with USB and Midi Interface
As the Dark Energy I had to be discontinued because an
important electronic part (CEM3394) is no longer available
we decided to do a redesign of the Dark Energy. The new
Dark Energy II looks like the Dark Energy I at first sight. But
the basic sound of Dark Energy II is clearly different from
version I because of the new circuits for VCO, VCF and
VCA. In the following description of the Dark Energy II the
differences to Dark Energy I are marked blue:
Dark Energy II is a monophonic stand-alone synthesizer
with USB and Midi interface. The sound generation and all
modulation sources are 100% analog, only the USB/Midi
interface contains digital components. Dark Energy is built
into a rugged black metal case with wooden side plates.
High quality potentiometers with metal shafts are used and
each potentiometer - except the filter mode control - is fixed
to the case (no wobbly shafts and knobs). The distance
between the controls is a bit wider compared to A-100
modules and knobs with vintage look are used.
VCO
· Sawtooth based VCO core
· manual tune control (with an internal jumper the range can
be set to ~ +/-1 half an octave or ~ +/-2.5 octaves)
· range switch -1 / 0 / +1 octave
· FM (frequency modulation) control with modulation source
switch (LFO1 / off / ADSR)
· manual pulsewidth control for rectangle waveform
· PWM control with modulation source switch (LFO2 / off /
ADSR)
· waveform switch (sawtooth / off / clipped/inverted
sawtooth) the sum of the waveform chosen by this
switch and the rectangle is fed into the VCF (to turn the
rectangle off the PW control has to be set fully CCW)
· external CV input for VCO frequency (1V/octave)
· external CV input for external PWM of the rectangle
· internal CV input for frequency (1V/octave) connected to
the CV1 output of the built-in USB/Midi interface
· because of the pure analog circuit and the temperature
control it may take up to 30 minutes until the VCO is in
tune.
VCF
· 12dB multimode filter with lowpass, notch, highpass and
bandpass mode control for continuous transition from
lowpass via notch to highpass and along to bandpass
· manual frequency control
· tracking switch half - off - full (internally connected to the
external frequency CV input of the VCO, i.e. the VCF
tracks to the VCO if the switch is set to "half" or "full"
position)
· exponential frequency modulation control (XFM) with
modulation source switch (LFO2 / off / ADSR), the XFM
control has polarizer function, i.e. the modulation source
(LFO2 or ADSR) selected by the Source switch may affect
Doepfer Musikelektronik GmbH
Geigerstr. 13 82166 Graefelfing/Germany
the filter frequency in a positive (right half of the control
range) or negative way (left half of the control range)
· manual resonance control (up to self oscillation)
· external audio input (this signal is added to the VCO
signal)
· external CV input for filter frequency
· 1V/octave tracking for usage of the VCF as a sine wave
oscillator over a few octaves (not as precise as the VCO
and not temperature compensated, but much better than
most of the other filters)
VCA
· manual amplitude control (initial gain)
· AM (amplitude modulation) control with modulation source
switch (LFO1 / off / ADSR)
· external CV input for VCA amplitude
· exponential scale.
LFO1 and LFO2
· manual frequency control
· waveform switch (triangle / off / rectangle)
· range switch (low, audio, medium)
· LED display (dual green/red color for positive/negative
share of the signal)
· the LFO1 signal is available as an additional socket (to
use the LFO1 signal for external modules)
ADSR
· manual controls for Attack, Decay, Sustain, Release
· range switch (long, short, medium)
· blue LED display
· ADSR signal is available as an additional socket (to use
the ADSR signal for external modules)
· External Gate input (normalled via switching contact of the
socket to the Gate output of the built-in USB/Midi
interface)
USB/Midi-Interface
· Midi channel and reference note are adjusted by means of
a learn button and LED at the rear panel
· The interface generates the gate signal that controls the
envelope generator and three analog control voltages:
CV1 is used to control the pitch of the VCO, CV2 the VCF
frequency (free assignable Midi controller) and CV3 is

available as an additional socket at the rear panel
(controlled by volume/velocity). It can be patched e.g. to
the VCA control input.
· The three CVs and the gate signal are also available at
the rear panel as jack sockets
· In/Outputs (all monophonic 3.5 mm jack sockets, except
USB, Midi and power supply)
· power supply (12...15V AC, min. 400mA)
Additional remarks and specs:
· As the LFO frequencies can go up to moderate audio
range (~ 5kHz) even audio FM effects of VCO (pitch and
pulsewidth), VCF and ADSR are possible !
· If the VCO is turned off and the VCF resonance is set to
maximum the module can be used as a sine oscillator.
The sine can be modulated in a linear manner from the
triangle wave of the VCO and by LFO2 in an exponential
manner at the same time !
· Weight: about 1.2 kg (without power supply)
· Distance between the knobs (center - center): ~ 25 mm,
diameter of the knobs: ~ 16 mm
· The metal case is made of 1 mm steel, black coated with
white printing
· Overall dimensions: about 185 x 145 x 75 mm
Doepfer Musikelektronik GmbH
Geigerstr. 13 82166 Graefelfing/Germany
· Dimension of the metal case only (without side plates and
knobs): about 145 x 135 x 55
· Side plates dimensions: about 145 x 65 x 12.5 mm The
wooden side plates can be removed if desired. They are
mounted by means of two screws to the metal box. The
holes in the metal box can be used also to mount several
devices together (e.g. with common wooden side plates
on both ends).
· The device can be positioned horizontal (desk top) or
vertical
· These parts are included: power supply (12 AC/min.
800mA) for 230V mains voltage with European mains
plug, one adapter cable 3.5 mm - 6.3 mm /1/4" jack plug
(1.5 m length), one USB cable (type A-B, 2 m length) and
two A-100 patch cables (50 cm length)
· Powering the device via USB is not possible, because the
analog circuits require a dual voltage (+/-12V).
· A lot of additional functions are available as internal pin
headers (e.g. VCO outputs, linear FM input for VCO, hard
SYNC input for VCO, VCF outputs, LFO outputs, LFO
connections for optional reset/direction features, ADSR
outout, inverter input and output).

DARK
TIME
2 x 8 Analog
Sequencer
with USB
and Midi
Dark Time is an 2 x8 steps analog sequencer with CV/Gate,
USB and Midi interface. It is planned in the first place as an
add-on for the Dark Energy but may be used even in
combination with other Midi, USB or CV/Gate equipment
too. Here is a list of the most important Features:
· two rows with 8 controls each
· for each step:
· one rotary control (same knob type as Dark Energy)
· one three-position toggle switch: On/Off/Skip:
· On = trigger signal is active for this step
· Off = no trigger output for this step
· Skip = step is skipped
· one three-position toggle switch: Stop/Continue/Jump:
· Stop = sequence stops here
· Continue = sequence continues
· Jump/Reset: if only one of the switches is in the Jump
position a Reset is carried out (jump to stage 1), if
two or more of the switches are in the Jump position
the sequence jumps to the next step with the switch
in the Jump position and then continues from this
position (until another step with the switch in the
Jump position is reached and then the same
procedure is carried out again)
· several operating modes:
· 1x16 (the two rows are daisy-chained)
· 2x8 (both rows run in parallel)
· Custom (user defined mode, e.g. three times row 1 and
the once row 2, not yet available in the first firmware
version !)
· several running directions
· forward
· backward
· random
· three voltage / tuning ranges: 1V, 2V, 5V (corresponding
to 1/2/5 octaves)
· quantization on/off/custom scale (custom scale not yet
available in the first firmware version)
when quantization is "off" the resolution is still 10 bit (i.e.
1024 steps over the full rotating range of each
potentiometer), from this the term "quantization off" is not
fully correct, with quantization "on" the resolution is
13/25/61 steps for 1/2/5 octaves

MIDI/ANALOG CONTROL KEYBOARDS
INTERFACE
R2M
MIDI RIBBON/
TRAUTONIUM
CONTROLLER
R2M is a ribbon controller that generates control signals by
moving the finger on the ribbon manual. The output signals are
generated as Midi and CV/Gate control voltages simultaneously.
Consequently R2M allows to control both Midi and CV/Gate based
equipment (e.g. analog synthesizers or analog modular systems).
R2M is the abbreviation for Ribbon to (2) MIDI.
R2M is made of two parts: the manual and the control box. For
the manual the same type as the for the modular version A-198 is
used. It includes a 50 cm position sensor and a pressure sensor.
The control box converts the data coming from the manual (finger
position and pressure) into the corresponding Midi data resp.
CV/Gate voltages. The control box is available even without
manual to make use of an already existing A-198 manual and take
advantage of the additional features of the R2M control unit
compared to the comparatively simple A-198. These are the most
important R2M features:
1. Manual
·precise and sensitive position sensor (length 50 cm) that
responds even to light finger touch
·pressure sensor located below the position sensor
·solid metal frame (double U-shape profile), silver-grey color
·several M3 threads on all sides (e.g. to mount the manual on a
base or to mount several manuals together or ...)
·measures: ~ 600 mm length x 30 mm width x 18 mm height
·weight: about 900 g
·connection to the control box via 4-pin cable (same as used for
USB connections but no USB function), 1m cable included
2. Control Box
·receives the analog resistance data coming from the position and
pressure sensor of the manual and converts these information
into Midi date resp. CV/Gate voltages
·operation via 10 buttons, 6 blue LEDs and illuminated 2 x 16
character LCD
·these MIDI messages can be assigned to the two sensors:
·note on/off without pitch bend
·note on/off with pitch bend
·pitch bend, after touch, any control change number
·program change
·"Trautonium" mode: in this special mode only a single note on
message is generated when the position sensor is touched. After
that only pitch bend messages are generated until the finger is
lifted off. Attention! This mode requires that the MIDI receiver
offers a sufficient pitch bend range (5 octave for max. R2M use)
and resolution so that no steps are heard over the complete
range. For details about the Trautonium please look at our web
site.
Doepfer Musikelektronik GmbH
Geigerstr. 13 82166 Graefelfing/Germany
·complete range. For details about the Trautonium please look at
our web site.
·Adjustable pitch bend width to adjust the R2M pitch bend to the
receiver's pitch bend
·12 bit pitch bend resolution
·MIDI channel, control change number and pitch scale can be
adjusted
·quantization option, i.e. only certain notes resp. control voltages
(e.g. only major or minor notes) are generated. For details please
refer to the A-100 quantizer module A-156 as the quantization of
the R2M is very similar.
·adjustable manual scaling (i.e. which length of the manual
corresponds to one octave, full length is max. 5 octaves)
·inverse scaling is possible (important if e.g. the manual is put on
with a strap)
·MIDI output
·resolution of the analog manual data: 12 Bit
·simultaneous output of MIDI data and CV/Gate voltages
·2 CV outputs:
·CV1 outputs the position sensor data (1V/octave standard,
0...max. +5V, i.e. max. 5 octaves)
·CV2 outputs the pressure sensor data (0...+5V)
·Gate output (corresponds to CV1)
·Gate can be configured as voltage gate (0/+5V) or switched
trigger (jumper inside the box)
·adjustable gate polarity:
·normal: 0 -> +5V when the sensor is touched
·inverse: +5V -> 0V when the sensor is touched
·CV output resolution: 12 Bit
·all settings (e.g. scaling, quantization, arpeggio and so on) affect
both MIDI and CV/Gate outputs
·CV hold and active Gate are possible at the same time (was not
possible for the A-198)
·no CV drift in hold mode (A-198 has a small CV drift in hold
mode)
·16 user defined presets (i.e. non volatile memory for 16 complete
settings of the unit)
·solid, silvergrey metal case (desktop shape)
·measures: about 128 width x 91 depth x 26 height (front) resp. 42
height (rear, because of desktop shape, measures in mm)
·weight: about 400g
·external power supply (7-12V DC / min. 250mA required)
·same manual as A-198 (if you already own an A-198 only the
R2M control box is required)
·from middle of 2011 the case color is changed to black (for both
the manual and the control box)

MIDI/ANALOG CONTROL KEYBOARDS
MAQ16/3
INTERFACE
MIDI Analog Sequencer
special edition with black
front panel and Dark Energy/
Time knobs
Designed in Cooperation with the German Band KRAFTWERK
Fans of vintage analog sequencers will be glad of the
MAQ16/3. It combines the creative potential of an
analog sequencer with the advantages of MIDI.
MAQ16/3 outputs the sequencing data both as control
voltages (CV) and as MIDI data. MIDI Out of the MAQ
may be connected to MIDI In of any sound generating
MIDI device (synthesizer, sampler) or to a computer
sequencer recording the MAQ data. Additionally 3
control voltage and gate outputs are available for
controlling vintage synthesizer equipment (e.g. the A100 Analog Modular System). The main feature of the
MAQ is the real time access to the sequence via 48
rotary potentiometers grouped in 3 rows of 16 dials
each. All important parameters like first/last step, MIDI
event, MIDI channel,
forward/backward/random/pendulum mode, gate time,
tempo and so on are independently assigned to each
row and can be changed in real time while the
sequence is running. This enables very complex
sequences. The rows may not only be used for
generating note events but also other MIDI events or
for controlling the length of time for each step. Of
course the MAQ allows the synchronisation via MIDI
Clock, Start and Stop either as master or as slave.
