Dark Energy: Monophonic Analog Synthesizer with USB and Midi
Dark Energy is a monophonic stand-alone Synthesizer with USB and Midi interface. The sound
generation and all modulation sources are 100% analog, only the USB and 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 potentiometers 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.
Dark Energy is made of these components:
VCO
•
•
•
•
•
•
•
•
•
•
•
Triangle based VCO core
manual tune control (by means of an internal jumper the range can be set to ~ +/-1 half an
octave or ~ +/-2.5 octaves)
range switch -1 / 0 / +1 octave
frequency range about 10Hz ... 12kHz
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 / triangle)
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), normalled to the CV output of the internal
USB/Midi interface
external CV input for pulsewidth of the rectangle
VCF
•
•
•
•
•
•
•
•
24 dB low pass
~ 12 octaves frequency range
manual frequency control
tracking switch half - off - full (internally connected to the frequency CV input of the VCO,
i.e. the VCF tracks to the VCO if the switch is set to "half" or "full" position)
XM: exponential FM (frequency modulation) control with modulation source switch (LFO2 /
off / ADSR)
LM: linear FM (frequency modulation) control to modulate the VCF by the triangle of the
VCO in a linear (!) manner
manual resonance control (up to self oscillation)
external audio input (this signal is added to the VCO signal)
•
•
external CV input for filter frequency, normalled to the auxiliary CV output of the internal
USB/Midi interface
1V/octave tracking for usage of the VCF as a sine wave oscillator (not as precise as the
VCO but much better than most of the other filters)
VCA
•
•
•
•
manual amplitude control
AM (amplitude modulation) control with modulation source switch (LFO1 / off / ADSR)
external CV input for VCA amplitude
special control scale: exponential scale in the range from about -20dB to -80/90dB, linear
scale from about -20dB to 0dB
Remark: this special control scale results in a loudness behaviour that is a bit different from
pure linear or exponential VCAs
LFO1 and LFO2
•
•
•
•
•
•
manual frequency control
waveform switch (triangle / off / rectangle)
range switch: low (up to several minutes period) / audio (up to ~ 5 kHz) / medium (usual
LFO range)
LED display (dual yellow/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)
an internal jumper can be used to select between the LFO1 signal or the inverted LFO1
signal
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 to the Gate output of the internal 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 threes CVs and the gate signal are also available at the rear panel as jack sockets
Remarks:
•
•
•
As the LFO frequencies include the audio range even audio FM effects of VCO (pitch and
pulsewidth), VCF and VCA are possible !
If the VCO is turned off (waveform switch = center position, pulsewidth control = fully CCW)
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 !
from the factory the socket labelled "LFO1" outputs the inverted LFO1 signal. But as the
module has several internal pin headers available even another signal may appear at this
socket by changing the internal module patch. These six pin headers are available: LFO1
output, LFO2 output, ADSR output, inverter input, inverter output, output socket. The
internal default patch is LFO1 -> inverter input, inverter output -> output socket (i.e. socket
= inverted LFO1). But even another signal can be patched to this socket (e.g. inverted
ADSR, non-inverted LFO1, inverted or non-inverted LFO2).
Dark Energy is also available as module A-111-5 for usage within the modular system A-100. The
only differences are the missing power supply and USB/Midi interface and the module uses the
standard distances between the controls. The VCO frequency CV input (1V/octave) and the Gate
input are normalled to the corresponding signals of the A-100 bus via jumpers. The jumpers can be
used to interrupt the internal bus connections.
Prices and availability:
Dark Energy: ~ Euro 400.00, Release date: June 2009
A-111-5:
~ Euro 300.00, Release date: May 2009
A-100 News
A-100 Monster Cases 6U and 9U
With angled mounting support
6U and 9U versions of the Monster Cases,
economically priced because only two power
supplies (instead of four) are required,
additional support for angled mounting of the
cases available (like the upper case in the
picture), in this case a Monster Base frame
fixed to the lower monster case is required
to avoid overturning of the complete
assembly.
Prices:
9U Monster Case: ~ Euro 850.00
6U Monster Case: ~ Euro 700.00
support for angled mounting: ~ Euro 30.00
Release date: ~ May 2009
A-187-1 DSP Effect Module
DSP based effects module with voltage
control of four parameters of the selected
digital effect (with manual control and CV
input with attenuator for each parameter).
The effect (e.g. reverb, delay, pitch-shifter,
distortion, equalizer) is selected by a 16position rotary switch. A detailed list with all
effects and the voltage controlled
parameters is available on our website. The
final version of the module may be equipped
with two audio inputs and two audio outputs
because the DSP board used in the module
features stereo audio processing. In this
case there is no more room for the audio
input attenuator. If necessary external
attenuators or VCAs could be used. The
final decision will be made after the Frankfurt
Musikmesse 2009.
Price: ~ Euro 200.00
Release date: ~ summer 2009
A-190-3 Polyphonic USB/MidiCV Interface
Four voice USB/Midi-to-CV/Gate interface.
For each voice a pitch control voltage (CV1,
to control VCOs), a gate output (to control
envelope generators) and two additional
control voltages (CV2, CV3) are available.
The two additional CV outputs are probably
controlled by velocity/volume and a free
assignable Midi controller. The mode is
selected by means of a rotary switch. These
modes are planned (without obligation):
unisono, four voice monophonic (i.e. to
control four monophonic voices by four
succeeding Midi channels), four voice
polyphonic (i.e. to control four monophonic
voices by one Midi channel). In the
polyphonic mode different assign algorithms
are planned. The final version will be
probably equipped with both USB and Midi
interface (USB socket is not shown).
Price: ~ Euro 200.00
Release date: ~ summer 2009
A-138m 4 x 4 Matrix Mixer
Matrix mixer with four rows (1 - 4) and four
columns (A - D), switches for
unipolar/bipolar mode for each column.
Unipolar means that the controls of the
column in question work as attenuators.
Bipolar means that the controls work as
polarizers. In this mode the amplification is
zero in the middle position of the
corresponding control. Turning the knob
counterclockwise from the center position
the signal is subtracted from the output sum
with increasing amount (i.e. negative).
Turning the knob clockwise from the center
position the signal is added to the output
sum with increasing amount. As the module
is DC coupled it can be used for both control
voltages and audio signals.
Price: ~ Euro 120.00
Release date: ~ June 2009
A-183-1 Dual Attenuator
Two passive attenuators. Passive means,
that each unit is made of two sockets and a
50k linear potentiometer only. There are no
active parts like amplifiers or buffers and no
power supply is required. This is how the A183-1 works: At the output socket appears
the attenuated input signal, i.e. zero level at
the fully CCW position and max. level and
the fully CW position.
Applications:
Adjustment of the level of CV or audio
signals to control other modules that do not
have attenuators or modules of other
manufacturers).
Price: ~ Euro 35.00
Release date: ~ June 2009
A-183-2 Offset/Attenuator
Voltage offset generator combined with an
attenuator/ polarizer for the input. A switch is
used to select attenuator or polarizer
function for the input control. At the output
appears a DC voltage that is adjusted with
the Offset control in the range 0...+5V or 5V...+5V (selectable by an internal jumper).
The DC voltage is overlaid by the attenuated
or polarized voltage that is fed to the In
socket. When the switch is in the Attenuator
position the control works as an usual
attenuator. When the switch is in the
Polarizer position the control works as a
polarizer, i.e. zero level appears at the
center position. Right from the center
position the In signal is added to the offset
voltage, left from the center position the In
signal is subtracted from the offset voltage.
Price: ~ Euro 40.00
Release date: ~ June 2009
A-183-3 Amplifier
DC coupled voltage amplifier that can be
used for both CV and audio signals. The
maximal amplification can be switched
between 1, 2 and 4 (in position 1 the module
does not work as a real amplifier but only as
attenuator). The level can be adjusted by
means of the Level control between zero
and the chosen maximum amplification
(1/2/4). Two overload LEDs indicate if the
output signal goes beyond +10V or becomes
less than -10V. Input and output are
equipped with miniature 2-fold multiples.
The main application of this module is to
adapt differing audio or CV levels between
different modules or systems. For example
VCO, LFO, ADSR or Gate levels between
modules of different manufacturers can be
increased or attenuated.
Remark: Not a preamplifier for microphones
or electric guitars !
Price: ~ Euro 40.00
Release date: ~ June 2009
A-174-2 Wheels CV Source
Modulation wheel module with two wheels,
factory setting: one spring loaded wheel with
bipolar voltage output (i.e. 0V in center
position, positive voltage in the upper range,
negative voltage in the lower range) and one
wheel without spring and positive voltage
output (i.e. 0V in the lowest position and
positive voltage when operated), the factory
setting can be changed by means of
jumpers (e.g. 2 unipolar wheels without
spring or two bipolar spring-loaded wheels)
Price: ~ Euro 60.00
Release date: ~ summer 2009
A-177-2 Foot Controller Module
Economically priced module for connecting
one foot controller and one double foot
switch for control A-100 functions by means
of the feet. For example the frequency of a
filter or the loudness can be controlled by a
foot controller, but even other parameters
like LFO frequency, modulation depth,
phasing, pitch or any other voltage
controlled parameter. The gate outputs
controlled by the double foot switch can be
used e.g. to trigger an envelope generator or
to start/stop a sequencer. A special
application of the A-177-2 is the usage
within a Trautonium replica. The foot
switches can be used to switch the mixtures
of the subharmonic oscillator A-113. The
foot controller can be used to control the
overall loudness in combination with a VCA.
A-177-2 is compatible with the
footcontrollers FP5 and double foot switch
VFP2.
Price: ~ Euro 40.00
