Voltage controlled bit modifier module for the Eurorack A-100 system
Notes: Module A-189-1 is a voltage controlled bit modifier. It offers several voltage controlled algorithmic functions like voltage controlled bit crunching, bit shifting (with/without carry over), bit exchange, rectifying, absolute value and calculating operations like addition, subtraction, multiplication or division.

The module has two control units both with manual control and CV input with attenuator:

- One for the algorithmic function according to the selected mode (e.g. number of shifted bits): BC and BC CV
- One for the sampling rate (SR and SR CV).

The signal input is equipped with an attenuator. As the module is DC coupled even control voltages can be processed.

The mode (e.g. bit crunching, bit shifting, bit exchange) is selected by a 16-position rotary switch.

Module for controlling the Trautonium ribbon controller - 8HP
Notes: Touching the sensor with a finger generates a control voltage CV1 that is proportional to the position of the finger. The scale (i.e. the relation between position difference and voltage difference) is adjustable with a potentiometer at the front panel. A hold switch is used to determine if the CV voltage is held after removing the finger (hold = on) or if the CV voltage jumps to 0V (hold = off). In the last case (hold = off) a gate signal is derived from the CV voltage whenever a finger touches the sensor (e.g. for triggering an envelope generator).

A sensitive pressure sensor located below the position sensor generates a second control voltage CV2 that increases with higher pressure of the finger. Even for CV2 the scale is adjustable. A second gate signal is triggered as soon as the pressure exceeds a certain value. The gate threshold is adjustable at the front panel.

The sensors are located in a separate metal frame (length about 600 mm, width about 30 mm, height about 18 mm, weight: about 900 g, colour: silver-grey). The connection between the module and the sensor frame is made by a 4 pin cable (same as used for USB connections).

Typical applications:

- Trautonium manual, the string is replaced by the position sensor that is much easier to use and cheaper than the string. In combination with the Subharmonic Oscillator A-113, the Trautonium Filter A-104 and some auxiliary modules a complete Trautonium replica may be realized. In combination with the Quantizer A-156 exact semitone intervals are possible.

- Ribbon Controller for any A-100 parameter

Complete miniature monophonic synthesiser module - 10HP
Notes: VCO:

- Tune: manual tune control (with an internal jumper the range can be set to ~ +/-1 half an octave or ~ +/-2.5 octaves)
- Oct: range switch -1 / 0 / +1 octave
- Mod: modulation depth (attenuator wired to the Mod. socket)
- Dest: switch that is used to address the modulation to frequency modulation (position FM) or pulsewidth modulation (positon PM), in centre positon no modulation
- PW: manual pulsewidth control for rectangle waveform, PW can be also modulated by the Mod. input as mentioned above
- Wave: 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 or fully CW)
- 1V/Oct. (socket): external CV input for VCO frequency (1V/octave)
- Access to internal bus CV (via jumper, optional, please remove the bus jumper if this feature is not used to avoid unwanted frequency modulation as then the unused CV line of the bus works as a kind of antenna)
- Triangle core VCO, frequency range about 32Hz ... 8kHz

Balance unit:

- The balance unit is made of two VCAs which are controlled by the sum of manual Balance control and the balance CV input in the opposite direction.
- The audio input of VCA1 is hard-wired to the VCO output, audio input 2 is connected to the socket Ext.In.
- The output of the balance unit is used as audio input for the VCF
- Bal.: manual balance control, fully CCW the internal VCO is used, fully CW the external signal (Ext.In) is used, at centre position both signals have about the same level
- CV Bal.: CV input for balance (range about 0...+5V)
- Ext. In: external audio input for VCA2, about 5 Vpp level required for similar loudness as the internal VCO
- This socket is normalled to the internal VCO suboctave f/2 signal (rectangle with half the frequency), if no external signal is applied the suboctave signal is used as the second signal for the balance unit

VCF:

- 24 dB low pass
- Frq: manual frequency control
- FM1: frequency modulation depth (attenuator wired to the VCF FM1 socket, the socket is normalled to the internal Envelope signal and then FM1 controls the modulation depth of the internal envelope applied to the filter)
- FM2 (socket) : second CV input for VCF without attenuator (about 1V/octave), can be used e.g. for VCF tracking by connecting the same CV which is used also for the VCO frequency
- Res: manual resonance control (up to self oscillation)
- If the VCO is turned off (waveform switch = centre position, pulsewidth control = fully CCW or CW) and the VCF resonance is set to maximum the module can be used as a sine oscillator, the tracking at socket VCF FM2 is about 1V/octave (not as precise as the VCO but much better than most other filters)
- ~ 11 octaves frequency range (~ 10 Hz ... 20kHz)

VCA:

- Gain: manual amplitude control (initial gain), can be used to open the VCA without envelope signal
- VCA (switch): used to switch between gate and envelope as control signal for the VCA, in centre position the VCA is not controlled by envelope or gate
- Note: when gate is used the VCA is controlled directly by the gate signal (i.e. hard on/off), this may lead to clicking noise under certain conditions (especially with low VCO/VCF frequencies)
- 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
- Out: audio output of the module (= VCA output)

Envelope:

- Gate (socket): Gate input (min. +5V), can be normalled to the bus gate signal by means of a jumper
- Att: manual control for Attack
- D/R: manual control for Decay/Release
- Env. (switch): used to switch between A/D, ADSR and A/R mode of the envelope generator, in centre position (ADSR) the sustain level is fixed to about 50%
- Envelope (socket): envelope output (about +10V)
- CVT (socket): CV input for time control, by means of two internal jumpers one can select which time parameters are controlled by the CVT input (e.g. A only or D/R only or A/D/R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question)
- Envelope LED display
- Attack time range: ~ 1ms ... 5 sec (can be extended by using the CVT input)
- Decay/Release time range: ~ 1ms ... 15 sec (can be extended by using the CVT input)

Analogue delay module - 14HP
Notes: The A-188-1 series bases on a co-called bucket brigade device (BBD) that has been used in the pseudo-digital BBD-delays.

The version with 256 stages provides a delay time of 0.51 - 256ms and is great for Karpluss-Strong synthesis.

The module is not an entire delay but only its core with all anomalies (e.g. cross talk of the internal clock frequency), and its very independent spacey and raw sound.

There are modulation possibilities with invertible polaritiy, a dry/wet control, feedback up to self-oscillation and a feedback loop with insert.

Midi/USB-to-CV/Gate interface - 6HP
Notes: Module A-190-3 is a Midi/USB-to-CV/Gate interface that allows the integration of the A-100 system into a USB or Midi environment. It has available 4 analogue control voltage outputs (CV1...4) and one Gate output. A-190-3 is the modular version of Dark Link.

In/Outputs and controls:

- USB
- Midi Input
- Learn button
- Gate Out (with LED for Gate display and learn function), 0/+5V
- CV1: controlled by Midi note messages, 1V/Octave, 0...+5V
- CV2: controlled by Midi pitch bend, ~ -2.5...+2.5V or ~ 0...+5V (can be selected by an internal jumper)
- CV3: controlled by Midi velocity, 0...+5V
- CV4: controlled by Midi control change messages, free assignable controller in learn mode
- Glide control (portamento function for CV1)

Other Features:

- Midi channel, reference note and Midi control change number for CV4 are adjusted by means of a learn button and LED.
- By means of two jumpers CV1 and Gate can be connected to the corresponding lines of the A-100 bus. That way the VCOs A-110 or A-111 and the envelope generator A-140 can be controlled directly via the A-100 bus, i.e. it's not necessary to patch CV and Gate with cables between the front panels. In addition, CV1 is buffered, i.e. even several VCOs can be controlled by the A-190-3 without the need of an additional bus buffer (e.g. A-185-1 or A-185-2).
- The gate voltage can be set to +5V or +12V by means of two jumpers. For modules of the A-100 both voltages can be used. For modules or devices from other manufacturers the gate voltage has to be set accordingly.
- If you want to connect the gate output to devices that use S-Trig a special S-Trig cable is available. For details please refer to our FAQ page
- By means of the precise CV adder A-185-2 CV1 and CV2 can be added to obtain an adjustable width of the pitch bend. For this CV2 of the A-190-3 is connected to the upper input of the A-185-2 which has an attenuator available. CV1 of the - A-190-3 is connected to one of the other inputs without attenuator.

Bucket Brigade Device module, 0 Stages - 14HP
Notes: Module A-188-1 is a so-called Bucket Brigade Device module.

BBDs have been used to delay audio signals before digital delays dethroned the BBD based effect units. But BBDs have some very unique advantages (or disadvantages dependent on the point of view) over the digital counterpart which result from the special properties of the BBDs. BBD circuits can be treated as a chain of Sample&Hold units (S&H) which pass on their voltages to the next S&H in the chain at each clock pulse.

In any case the sounds generated by module A-188-1 are very special. Typical applications are: Flanger, Chorus, Analog Delay or Karplus/Strong synthesis. But as the A-188-1 has a lot of very unique features (voltage controlled clock rate / delay time with extreme range, polarity switches for the CV inputs, feedback and BBD out/mix, clock and CV output of the high speed VCO, BBD clock input, feedback insert, feedback up to self-oscillation) a lot of unusual applications can be realized with the module (e.g. delay controlled by ADSR, envelope, random or sequencer with positive or negative effect).

The A-188-1 also has no built-in anti-aliasing filter in order not to limit the possibilities of the module. For this the CV out is intended.

This module comes without BBD circuit. The final adjustment is possible only with the BBD circuit used in the module. Electronic experience and measuring equipment (digital multi-meter, oscilloscope, frequency meter) are required.

Miniature PSU/bus board
Notes: The A-100 MNT (Mini power supply/bus) is composed of a miniature power supply and system bus, with connectors for four modules. It's designed to be used with a small set-up of just a few modules, in your own custom-designed case. The idea is that then you can use individual A-100 modules - for instance the filters, the filterbank, frequency shifter, sampler, MIDI interface, etc. - as free-standing pieces of equipment, which can easily be integrated with your other instruments or recording equipment.

The power supply provides the usual A-100 system requirements of +12 V and -12 V, and an additional +5 V supply, for the few modules (for instance A-190, A-191) which need it. The maximum current loading capacity totals 100 mA for +/- 12 V and/or 50 mA for the +5 V supply.

The system bus provides connections for four System A-100 modules. As well as the power supply, it also carries "INT.CV" and "INT.GATE" connections (see A-100 manual, main introduction, chapter 3, 'The A-100 signal flow'.).

The A-100 MNT is supplied as standard with an external power supply, which has to be connected to the socket on the MNT's circuit board.

Bucket brigade delay module - 30HP
Notes: A-188-2 is another module that is based on a so-called Bucket Brigade Device (BBD). If you are not familiar with BBDs please refer to the A-188-1. There you can find some details about this special type of circuits.

The main difference between A-188-1 and A-188-2 is the type of BBD circuit that leads to completely different module principles and sounds. The A-188-1 uses different single BBD chips with one signal input and one signal output only. In contrast the A-188-2 uses as so-called tapped BBD that has available six outputs - the so-called taps after the BBD stages 396, 662, 1194, 1726, 2790 and 3328. In the A-188-2 we use this special BBD circuit (MN3011) to obtain these module features:

The module has available two separate mixing sub-units. For both mixers the levels and polarities of each BBD output can be adjusted to obtain two different mixtures of the BBD outputs. A new type of potentiometers with centre detent and centre terminal is used for the BBD mixing controls to have a better feel for the neutral position. Each mixer has a wet/dry control at its output that allows choosing between the pure input signal (original), the BBD mix or anything in between. The two outputs can be treated as stereo outputs but it is also possible to use one of the outputs for other applications (details in the next paragraph).

The A-188-2 has a feedback section available that is very similar to the one in the A-188-1. But as we now have 6 different BBD outputs available 6 different feedback types are possible. The feedback input socket is normalled to the "396" output (not to "1194" as shown in the scheme, the front panel is correct). But by patching the feedback socket to any of the single output sockets another BBD tap can be used for the feedback to obtain different sounds. Even external feedback processing is possible (e.g. with a VCA for voltage controlled feedback). The feedback control has polarizer function, i.e. the neutral position is at the centre. Left from the centre the feedback signal is subtracted from the input signal, right from the centre it's added (negative/positive feedback). Even for this potentiometer the new version with centre detent is used.

A special feedback can be obtained if one of the mix outputs is used for the feedback function. In this case for each tap the positive or negative feedback share can be adjusted. This leads to multiple peaks and/or notches in the frequency response of the module.

For each tap of the BBD a separate output socket is available. These sockets can be used for changing the feedback loop - as mentioned above -, for voltage controlled mixing of the taps - e.g. with the voltage controlled mixer A-135 or other applications that require access to each single tap.

The A-188-2 uses the same high speed VCO (HSVCO) for the BBD clock as the A-188-1. The clock and consequently the delay time can be controlled manually (delay control) and by the two control voltage inputs CV1 and CV2. The sensitivity of CV1 is approximately 1V/oct. CV2 is equipped with a polarizer (a new type of potentiometers with centre detent). The HSVCO has a clock output available that is normalled to the clock input socket. These sockets can be used to link different BBD modules and to run them with the same clock. But even other applications with frequency dividers (e.g. A-163) or PLL (e.g. A-196) are conceivable. A voltage composed of the manual delay control, CV1 and CV2 is available at the CV out socket, e.g. to control an external clock suppression filter as the A-188-2 is not equipped with such a filter (same as for the A-188-1).

Midi/USB-to-CV/Gate interface - 6HP
Notes: Module A-190-3 is a Midi/USB-to-CV/Gate interface that allows the integration of the A-100 system into a USB or Midi environment. It has available 4 analogue control voltage outputs (CV1...4) and one Gate output. A-190-3 is the modular version of Dark Link.

In/Outputs and controls:

- USB
- Midi Input
- Learn button
- Gate Out (with LED for Gate display and learn function), 0/+5V
- CV1: controlled by Midi note messages, 1V/Octave, 0...+5V
- CV2: controlled by Midi pitch bend, ~ -2.5...+2.5V or ~ 0...+5V (can be selected by an internal jumper)
- CV3: controlled by Midi velocity, 0...+5V
- CV4: controlled by Midi control change messages, free assignable controller in learn mode
- Glide control (portamento function for CV1)

Other Features:

- Midi channel, reference note and Midi control change number for CV4 are adjusted by means of a learn button and LED.
- By means of two jumpers CV1 and Gate can be connected to the corresponding lines of the A-100 bus. That way the VCOs A-110 or A-111 and the envelope generator A-140 can be controlled directly via the A-100 bus, i.e. it's not necessary to patch CV and Gate with cables between the front panels. In addition, CV1 is buffered, i.e. even several VCOs can be controlled by the A-190-3 without the need of an additional bus buffer (e.g. A-185-1 or A-185-2).
- The gate voltage can be set to +5V or +12V by means of two jumpers. For modules of the A-100 both voltages can be used. For modules or devices from other manufacturers the gate voltage has to be set accordingly.
- If you want to connect the gate output to devices that use S-Trig a special S-Trig cable is available. For details please refer to our FAQ page
- By means of the precise CV adder A-185-2 CV1 and CV2 can be added to obtain an adjustable width of the pitch bend. For this CV2 of the A-190-3 is connected to the upper input of the A-185-2 which has an attenuator available. CV1 of the - A-190-3 is connected to one of the other inputs without attenuator.

Analogue delay module - 14HP
Notes: The A-188-1 series bases on a so-called bucket brigade device (BBD) that has been used in the pseudo-digital delays of the 1980s.

The version with 512 stages provides a delay time of 1.02 - 512 ms.

The module is not an entire delay but only its core with all anomalies (e.g. cross talk of the internal clock frequency), and its very independent spacey and raw sound.

There are modulation possibilities with invertible polaritiy, a dry/wet control, feedback up to self-oscillation and a feedback loop with insert.

Electronic switch with up to four steps - 4HP
Notes: Module A-151 (Quad Sequential Switch) is like an electronic four-position rotary switch.

It includes trigger and reset inputs, four in / outputs, and a common out / input. Each time a pulse is received at the trigger input socket, the common out / input is connected to the next in / output. After the fourth in / output, the next trigger makes it step back to the first again, and so on. A positive pulse at the reset input switches the out / input immediately back to the first in / output (see Fig. 1). Voltages in the range -8V...+8V at the O/I resp. I/O sockets can be processed by the module.

Four LEDs indicate the active in / output (i.e. the on that is connected to the out / input at any particular time).

12dB multi-mode filter - 8HP
Notes: Module A-106-5 is a 12dB multimode filter that is based on the filter circuit of the Oberheim SEM module.

The filter is equipped with a band pass output and a combined low/notch/high pass output. For this output a control knob defines the relation between low and high pass signal. If both signals appear at the same level (i.e. middle position of the Mix knob) one obtains a notch filter. Otherwise the low or high pass signal predominates.

The module does not feature self-oscillation in contrast to most of the other filters of the A-100 system.

The module generates a distorted audio signal if the level control is set to about 50% (i.e. centre position) or more with A-100 standard signals like VCOs.

Quad low frequency oscillator - 4HP
Notes: Module A-145-4 is a simple quad LFO (Low Frequency Oscillator). Not a very "exciting" module, just a bread-and-butter device and a simple demon for work. Virtually in every modular system several LFOs are required for modulation purposes. The module contains four simple LFOs with the waveforms triangle and rectangle. A dual colour LED (red = positive / yellow = negative output voltage) indicates the triangle output of each LFO. The frequency range can be chosen for each LFO individually by means of a jumper between about 50 Hz ... 0.04 Hz (about 20 seconds, jumper removed) and about 2Hz ... 0.002 (about 8 minutes, jumper installed).

The module can be treated as a slimmed version of the quad LFO A-143-3 as it has similar features available. But the distances between the controls are smaller and rubberized small-sized knobs are used. In return the front panel has 4 HP only which is less than one third of the A-143-3. The module is primarily planned for applications where only limited space is available. The functional difference compared to the A-143-3 are the missing sawtooth outputs and frequency range switches.

Examples:

- All switches in left position or all switches in right position: 8-fold multiple

- Four switches in left position and four switches in right position: two 4-fold multiple

- X switches in left position, Y switches in right position and Z switches in centre position: two separate multiples with some sockets turned off

Envelope module with two ADSR voltage controlled enevelope generators - 8HP
Notes: The module contains two ADSR type voltage controlled envelope generators with exponential curve shapes (charge/discharge curves of a capacitor) behind a front panel with 8 HP only.

Each ADSR provides these controls and in/outputs:

- LED (displays the envelope output)
- A: manual Attack control
- D: manual Decay control
- S: manual Sustain control
- R: manual Release control
- Gate Input
- Retrigger Input
- CVT Input with attenuator (CVT = CV Time)
- Envelope Output 1
- Envelope Output 2

The output voltage range for each envelope is 0 - 10V (10V = attack peak).

The time range of Attack/Decay/Release is about 1ms to 30s.

By means of internal jumpers one can select which time parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question).

Socket CVT can be normalled to an internal fixed voltage (i.e. the switching contact is connected to an internal fixed voltage). That way it's possible to change all time parameters simultaneously by means of the CVT control.

Another jumper is used to set output 2 to normal or inverted envelope.

And another jumper is used for the normalling of Gate 2 to Gate 1 (i.e. ADSR#2 is also triggered by Gate 1).

Two more jumpers are used for the optional bus access to the gate signal of the bus for each ADSR.

Precision adder (mixer) and buffer for control voltages - 6HP
Notes: Module A-185-2 is a precision control voltage adder/buffer. Precision means that the amplification of the inputs without attenuators is exactly 1.00 and is suitable to add control voltages for the pitch control of VCOs (e.g. from keyboard + sequencer 1 + sequencer 2). Summing resistors matched to 0.1% are used to obtain an accuracy of 0.1% for the added voltages.

The module is equipped with four CV inputs: one with attenuator and three without attenuator. Each input is normalled to +1 V (i.e. if no plug is inserted the input contributes 1 V to the sum appearing at the output).

The input with attenuator can be used for common modulations (e.g. from an LFO, ADSR, Theremin, Pitch-Bender) for all VCOs connected to the output. The Lev.1 control is used to adjust the depth of the modulation, the first switch selects the polarity of the modulation. If no signal is connected to the first socket the attenuator works as a (fine) tuning knob because a voltage in the range 0...+1V (right position of the switch) or 0...-1V (left position of the switch) is added to the CV output.

The inputs without attenuators are planned to add control voltages coming out of keyboards, sequencers, Midi-to-CV interfaces, ribbon controllers or other CV sources that follow the 1V/oct standard. For example the CV of a keyboard can be used to transpose the CV coming from a sequencer, or the CV of a slow sequencer can be used to transpose the CV from a fast sequencer.

Each input is equipped with a three-position switch that determines if the corresponding voltage is added (right position), subtracted (left position) or if the input has no effect (centre position). If no plug is inserted the corresponding switch works as an octave switch for the lower three sections as the default 1 V are added or subtracted to the output voltage according to the switch position. The first switch can be used to add a variable voltage to the sum output. The variable voltage is adjusted with the Lev.1 control and the knob works then as kind of a (fine) tuning control.

The module is equipped with 4 outputs: three non-inverting and one inverting ouput. An internal jumper can be used to connect the non-inverted or inverted output to the CV line of the A-100 bus. That way the module can used to control several VCOs that are connected to the same bus board as the A-185-2 (same functionality as A-185-1).

Compact two-channel VCA - 4HP
Notes: Module A-130-2 is the slim version of module A-132-3 and offers essentially the same features. But the distances between the controls are smaller and rubberized small-sized knobs are used. In return the front panel has 4 HP only which is half the width of the A-132-3. The module is primarily planned for applications where only limited space is available.

The module is composed of two identical voltage controlled amplifiers (VCA). Each VCA has a manual gain control (also named Initial Gain) and a control voltage input with attenuator. The character of the control scale can be switched to linear or exponential. All inputs and outputs are DC coupled. Consequently the VCAs can be used to process both audio and control voltages (e.g. for voltage control of the level of LFO or envelope signals). The signal input has no attenuator available but is capable to process up to 16Vpp signals (i.e. -8V...+8V) without distortion. For the processing of higher levels an external attenuator (e.g. A-183-1) is recommended.

The amplification range is 0...1. Even with a higher external control voltage the amplification remains at 1 (kind of "amplification clipping" at 1).

Controls (for each of both units):

- Gain: manual gain control (Initial Gain) in the range 0...1
- CV: attenuator for the CV input
- Lin/Exp: switches the VCA characteristic to linear or exponential, in center position the VCA is off (mute function)

Inputs and outputs (for each of both units):

- CV: control voltage input, min. +5V required for max. amplification (1) with CV control fully CW and Gain fully CCW
- In: signal input, max. 16Vpp (+8V...-8V) without distortion
- Out: signal output

Dual trigger modifier, consisting of two trigger inverters for gate, clock or trigger signals - 4HP
Notes: Module A-165 (Dual Trigger Modifier) contains two separate trigger modifiers, to use with logical/digital levels (gate, clock, trigger). Each half of the module enables signals generated by the A-100 to communicate with other instruments (such as an external sequencer) or is simply used where you want to reverse a trigger polarity.

Whatever signal is patched into the input, inverted by the module, and fed out of the Inv. Out (inverted output) socket. At the same time, a trigger signal of roughly 50 ms is generated every time an edge of the trigger pulse is sensed (negative as well as positive). This trigger signal is available at the +/- output.

Two LEDs act as indicators showing the level of signal available at the two outputs.

When both units are daisy-chained the module can be used as level shifter for gate/trigger/clock signals (from min. +2,5V up to +12V)

Noise/random generator - 4HP
Notes: Module A-118-2 is the slim version of module A-118-1 and offers essentially the same features as the A-118-1. But the distances between the controls are smaller and rubberized small-sized knobs are used. In return the front panel has 4 HP only which is half the width of the A-118-1. The module is primarily planned for applications where only limited space is available. The functional difference between A-118-1 and A-118-2 is the additional T&H/S&H unit which is not included in the A-118-1.

The module generates the signals white noise, coloured noise, continuous random voltage and stepped random voltage (derived from the continuous random voltage by means of a S&H/T&H unit).

The noise signal is generated 100% analogue by amplification of the noise of a transistor. White and coloured noise are usually used as audio sources. The random voltages are normally used as control voltages (e.g. for filter frequency or any other voltage controlled parameter).

The A-118-2 gives you the ability to mix the relative amounts of Red (low frequency component) and Blue noise (high frequency component) in the coloured noise output.

For the continuous random voltage the rate of change (Rate) and amplitude (Level) of the random voltage can be adjusted. The continuous random voltage is derived from the coloured noise signal by low pass filtering. Consequently the settings of the controls for the coloured noise (Blue, Red) affect the behaviour of the random voltage! A dual colour LED (red = positive / yellow = negative output voltage) indicates the continuous random voltage.

The continuous random voltage is used as source for the S&H/T&H unit. The type of operation can be set to S&H (sample and hold) or T&H (track and hold). When T&H is chosen the output signal follows the input signal (= continuous random voltage) as long as the Clock input is "high". As soon as the clock signal changes to "low" the last voltage is stored. When S&H is chosen the input signal (= continuous random voltage) is sampled at the rising edge of the Clock signal.

For the Clock signal a "digital" signal (e.g. Clock, Gate, rectangle output of an LFO) is required. It does not work with slowly changing continuous CV signals. Another dual colour LED (red = positive / yellow = negative output voltage) indicates the stepped random voltage.

Voltage controlled 12dB/octave filter - 8HP
Notes: Module A-121-3 is functionally nearly identical to module A-121-2. Only the distances between the controls and sockets are smaller and rubberized, small rotary knobs are used. Therefore the front panel width is only 4HP compared to 8HP of the A-121-2. In the first place it is planned for applications where only limited space is available. The only functional difference compared to the A-121-2 is the missing attenuator for the resonance CV input CQ.

These are the most important features of the module:

- Voltage-controlled multi-mode filter with a cut-off slope of -12 dB / octave (identical to the filter of the Dark Energy II/III but has been expanded by the voltage controlled resonance feature)
- Four simultaneous outputs are available, each with different characteristics: low-pass (LP), high-pass (HP), band-pass (BP) and notch (N)
- Manual control Frequ. for the cut-off frequency of the filter (the cut-off frequency determines the point at which the respective filter effect appears)
- Two inputs for frequency control by means of external control voltages (frequency modulation, e.g. by ADSR or LFO):
- Control voltage input CV1 without attenuator, about 1V/octave sensitivity
- Control voltage input CV2 with attenuator FCV2 for the adjustment of the modulation depth of input CV2
- Frequency range about 10Hz ... 20kHz
- Manual control Q for the resonance of the filter
- Control voltage input CQ without attenuator for voltage control of the resonance
- Resonance up to self-oscillation, in which case the module will behave like a sine wave oscillator even without audio input signal
- Audio input In with attenuator Level for the adjustment of the filter input level (beyond about pos. 5 clipping/distortion occurs with typical A-100 audio levels)

Simplistic quad LFO module with intuitive front panel - 14HP
Notes: Module A-143-3 is a low-cost four-fold modulation oscillator, often called LFO (low frequency oscillator). Like the other modules of the A-143 series (A-143-1 and A-143-2) not a very "exciting" module, just a bread-and-butter device and a simple demon for work. The module contains four simple LFOs. Each LFO is equipped with three waveform outputs: triangle, rectangle and rising sawtooth. The frequency of the sawtooth output is twice the frequency of the other outputs. A three-way switch is used to select one of three frequency ranges mid-low-high, spanning from about two cycles per minute at the lowest, to moderate audio frequency at the highest (about 5 kHz).

If other waveforms or additional LFO features are required (e.g. reset input, adjustable waveform, voltage controlled frequency) the LFO modules A-145, A-146 and A-147 are available.

Compact module for attenuating control voltage signals - 4HP
Notes: Module A-183-2 is a voltage offset generator combined with an attenuator/polarizer.

This is how the A-183-2 works: At the two output sockets (simply two connected sockets) appears a DC voltage that is adjusted with the Offset control in the range 0...+5V or -5V...+5V. An internal jumper is used to select the offset range (0...+5V or -5V...+5V). Other ranges are possible by changing a resistor on the pc board (e.g. 0...+10V or -10V...+10V). The DC voltage generated by the Offset control is overlaid by the attenuated voltage that is fed to the In socket. The function of the attenuator control can be set to Attenuator or Polarizer by means of a toggle switch. When the switch is in the Attenuator position the control works as an usual attenuator, i.e. zero level at the fully CCW position and max. level and the fully CW position. When the switch is in the Polarizer position the control works as a polarizer, i.e. zero level appears at the centre position. Right from the centre position the In signal is added to the offset voltage, left from the centre position the In signal is subtracted from the offset voltage. In other words: at the fully CW position the non-inverted In signal is added with the full level to the offset voltage, at the fully CCW position the inverted In signal is added with the full level to the offset voltage.

The amplification range for the input is about 0...+1 in the attenuator mode, and -1...+1 in the polarizer mode. The amplification range can be modified by replacing a resistor by another value.

Applications:

Generation of adjustable DC voltages overlaid by control voltages with adjustable level and polarity to control other modules that do not have attenuators or offset controls, e.g. Sampler A-112 (mainly for the wavetable mode), dual VCA A-132-1, VCLFO A-147-2 for waveshaping and ring modulator applications, Quantizer A-156, Theremin A-178, CV-to-Midi interface A-192 and modules of other manufacturers).

Analogue sequencer for CV's & trigger/gates
Notes: The Doepfer A-155 has two CV rows, each with selectable voltage range, glide and sample & hold options. Three trigger rows and a one gate row. Logic inputs for clock, reset, start and stop. It's even possible to insert external signals per step instead, overriding the CV generated by the 2nd row's potentiometer. The A-155's functions can be expanded by the A-154 Sequencer Controller, as it's an entire control unit with step number limitation, voltage controllable clock generator, variable gate length and a number of playback modes.

Features of the analogue rows (knobs):

- 8 potentiometers (knobs)
- Lower row: Scale (knob), voltage output range 0 ... ~ +6,5V
- Upper row: 1V/2V/4V (octave range switch for exact VCO control), voltage output ranges 0 ...1.0V / 0 ...2.0V / 0 ...4.0V
- Glide time (knob), same as portamento or slew limiter
- Glide Control (control input for switching glide on/off)
- S&H Control (control input for internal S&H, works like A-148)
- Pre Glide/S&H-Out (analogue output before S&H and glide unit, especially required when external audio signals are used as inputs of the lower row)
- Post Glide/S&H-Out (analogue output after S&H and glide unit)
- Lower row: external inputs for the 8 steps (switched jack sockets), control signals or audio signals may be used as inputs (allowed voltage range -5V...+12V), the knobs of the lower row are working in this case as attenuators

Features of the trigger rows (switches):

- 4 Trigger/Gate tracks with 2 rows of switches
- Toggle switches of 1-0-1 type (with middle position), which can be used to send a trigger/gate to the track above or below or to send no trigger/gate (middle position)
- 3 trigger rows (i.e. short pulse for each step set, pulse width corresponds to the pulse width of the clock/step input signal)
- 1 gate row (i.e. a high signal is applied during the length of the step set)

Control inputs and buttons:

- Step (defines the tempo of the sequence, same as clock or trigger input)
- Reset (resets all rows to step 1)
- Start (starts the sequence at the momentary position)
- Stop (stops the sequence at the momentary position)

Step and Reset are compatible to the MIDI interface A-190, i.e. in combination with the A-190 the A-155 may be synchronized via MIDI. The quantizing module A-156 can be used to quantize the infinite analogue voltages coming from A-155 into discrete semitone steps (multiples of 1/12V). Without MIDI interface e.g. a LFO rectangle output can be used to define the tempo of the sequence.

The sequencer controller A-154 adds a lot of new functions to the A-155 (e.g. voltage controlled addressing, forward/backward/pendulum/random mode, voltage control of first and last step, voltage controlled clock and gate length, step skipping, combination of several A-155 in parallel/serial mode and many more).

Notes: The A-100LC1v is a smaller version of the A-100LC3 with 48 HP of space. It is made out of raw wood, a black coating gives the Eurorack frame a vintage look. The built-in power supply, type A-100SSB, delivers up to 380 mA at +12 V and -12 V as well as 100 mA at +5 V.

The A-100LC1v comes equipped with one 48 HP measuring row for 3U modules. Its power supply features eight connectors for oscillators, filters and so forth. The case is connected to the grid via an IEC power socket.

Two separate slew limiters for generating portamento effects - 8HP
Notes: Module A-170 contains two separate slew limiters, also known as portamento controllers or integrators. The first SL has just one joint control, which sets both rise and fall times (c. 0 ...10 sec). The second SL has separate controls for rise and fall times, and can therefore be used as a simple AR envelope generator. Over and above this, you can set the overall range for these parameters, with a three-position switch, as on the full ADSRs.

Both slew limiters have two LEDs each, to show the state of the rising and falling voltages.


Additional technical remarks: If the upper slew limiter is used for precision applications (e.g. portamento/glide of one or more VCOs) a buffer (e.g. A-185-1 or A-185-2) is recommended between the A-170 output and the VCO(s) input(s). The reason is a small voltage drop that is caused by the protection resistor at the A-170 output. An A-185-1 or A-185-2 connected between the A-170 and the VCO(s) avoids that voltage loss. For all A-170 manufactured later than May 2009 (recognizable by the label "Version 2" on the pc board) this remark is not valid as these modules are equipped with an additional voltage buffer at the output.

The lower slew limiter cannot be used for precision applications because of the voltage loss caused by the diodes of the circuit.

8HP dual trigger delay for Eurorack
Notes: Module A-162 contains two identical circuits that generate a trigger signal with adjustable delay and length from an incoming rectangle signal (e.g. gate, trigger, rectangle output of an LFO or VCO). The rising edge of the incoming signal is used to trigger the new trigger signal. This module makes it possible to delay the onset of a trigger pulse, and also change its length.

On each of the two units, two controls can alter the onset time and duration of triggers, from about 2 ms up to more than 10 seconds. A control LED shows the generated signal.
