32HP metal enclosure for Eurorack modules with built-in power supply - Beta version
Notes: Limited Beta version of the popular Pod32. These are new, fully tested and functional units. The only difference between the Pod32 Beta and the regular Pod32 is that the Beta version has fewer holes to screw in modules. Most common Eurorack sizes will fit from 4HP to 32HP, but some odd sizes and combinations won't fit. Please refer to the product image, or visit the 4ms website for possible module combinations.

This Pod requires a power brick (not included). Or, if you already have a Pod and power brick (or a Row Power module) you can use a barrel cable to daisy-chain power supplies.

Pods are a perfect way to get started in Eurorack module, or add a couple more modules to your monster system!

Made from 100% anodized aluminium, Pods are light, tough and perfect for on-the-go set ups. Mix and match your Pods with desktop synths, effect pedals, drum machines or any musical gear for a flexible modular system. Need to add another module? Just add a Pod! Need to pack light for a live set? Just grab the Pods you need and go!

25W Eurorack power supply
Notes: The Row Power 25 is a clean, regulated, and protected power supply module for Eurorack systems. It requires a barrel-style power brick (15V - 20V DC) and supplies power to modules via flying bus cables, direct connection, and/or bus boards.

The Row Power 25 provides 25W of power for any Eurorack modules (typically 4-10 modules*):

+12V @ 1.4A maximum, 1.0A recommended
-12V @ 0.8A maximum, 0.5A recommended
+5V @ 1.0A maximum, 0.8A recommended

*number of modules can vary depending on each module's power consumption.

Simply plug a universal power supply (laptop style) into either of the barrel plugs on the 4HP panel. Connect your modules via flying-bus cables or the Bus Stick.

Multiple Row Power modules can be powered from a single power brick by daisy-chaining with an inexpensive barrel cable. The Row Power 25 can also be daisy-chained to Pods. Each Row Power and Pod will be independently regulated and protected for ultra-low cross-talk between rows.

Smart, versatile controller with 25 high quality keys, travel-friendly features & powerful software included - black & white edition
Notes: A new controller keyboard from Music tech pioneers Arturia that excites both new users and experienced professionals alike. MicroLab is a small-scale MIDI keyboard with smart design features that you can take anywhere.

THE KEYS:

MicroLab features the same professional slim-keys as their industry standard KeyStep controller. The keybeds found on budget controllers are often not very inspiring, but the 25 expressive, velocity-sensitive keys on MicroLab are simply a joy to play. The hold button gives you instant sustain, and by holding the shift key, you can access the "Chord" mode, letting you program in a chord and replay with just one finger.

THE FEATURES:

The rubberized shell protects MicroLab from and bumps and scrapes when you're on the move, and also features a recess that perfectly fits the USB cable, letting you store or pack it easily. MicroLab also includes capacitive mod and pitch controls that work in the same way that touchscreens do, these also let you swipe through and select presets with a tap. You can also quickly switch MIDI channels via the dedicated knob and numbered keys.

THE SHAPE:

Arturia have designed this controller to work with you, and not get in the way. Because the cable is recessed, you can push it right up against other gear in your studio without cables getting in the way. It's the width of the average plane and train tray table, and the shell stops it from sliding around. The keys are also recessed slightly into the body, nothing sticks out, so there's nothing to catch when you slip it into your backpack.

THE SOFTWARE:

MicroLab includes 3 great software titles for free:

- Analog Lab Lite - Explore 600 fantastic presets taken from Arturia's award-winning V Collection series. Analog and digital synths, classic organs and pianos.

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.

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.

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

VCA with exponential response for low level sensitivity - 8HP
Notes: Module A-131 provides voltage-controlled amplification. For audio signals, you would normally use the exponential VCA (A-131), and for control voltages, the linear VCA (A-130). It doesn't always have to be that way, though.

The amount of amplification the VCA's provide is determined by the voltage at the CV input, and the position of the gain control, which sets the overall gain in the system.

The VCA has two audio inputs, each with an attenuator. They are amplified by an amount determined by the combination of the gain and the two CV controls.

Multi-featured mixer - 6HP
Notes: Module A-138i is a four channel mixer with an additional mute switch for each input. On top of that it is equipped with two types of single outputs and a dual mix output. All inputs and outputs are DC coupled. Consequently the VCAs can be used to mix both audio and control voltages.

Each input is - apart from the mute switch - equipped with the usual attenuator.

The single outputs offer the attenuated and possibly muted signal of the channel in question. Two version of single outputs are available:

Single Output A: If a plug is inserted into the single output "A" socket the channel in question is removed from the sum signal.

Single Output B: If a plug is inserted into the single output "B" socket the channel in question is not removed from the sum signal. This type of single outputs is available only for the channels 1 and 2.

The output is twice available (two sockets, hard-wired like a multiple).

The distances between the controls and sockets are smaller as for the standard A-100 modules and rubberized small-sized knobs are used. In return the front panel has 6 HP width only. The module is primarily planned for applications where only limited space is available.

Versatile module that can also be used as a modulation device - 8HP
Notes: Module A-140-1 is an envelope generator, and, since it puts out control voltages, counts as one of the modulation devices in a modular system. As soon as the gate input receives sufficient voltage, the ADSR generates a variable voltage, changing in time, called an envelope. This varying voltage is output in normal (positive) and inverted form, and can be used, eg. for voltage controlled modulation of a VCO, VCF, or VCA, or for processing other modules' inputs and outputs.

The shape of the envelope is governed by four parameters: Attack, Decay, Sustain and Release.

The envelope is started (triggered) by a gate signal either from the INT.GATE voltage on the system bus, or, if a signal is put into it, from the gate input socket.

The envelope can also be re-triggered, i.e. start from scratch again, each time a trigger signal is sensed at the Retrig. input socket, when the gate is still open.

Module A-140 has available a three-position toggle switch to select one of three time ranges. The time ratios for the three ranges are about 1 : 20 : 1000. The absolute Attack times are about:

20uS ... 100ms (switch position L)
400uS ... 2s (switch position M)
20ms ... 120s (switch position H)
The Decay and Release times are about 3-4 times more. Because of the exponential slope and the gradual asymptotic approach to the zero level the exact specification of the decay and real times is a bit difficult.

The voltage ranges of the ADSR outputs are about 0 ... +8V for the two normal outputs and 0 ... -8V for the inverted output.

In combination with the Comparator module A-167 a free-running "ADSR-LFO" can be realized.

Voltage controlled envelope generator with decay parameter - 8HP
Notes: Module A-142-1 is a voltage controlled envelope generator. The only time parameter is decay (like TB303). Decay may be adjusted manually and via voltage control input (with attenuator). The envelope output is displayed with LED control. Additionally from the envelope signal a Gate signal and an inverse Gate signal with adjustable threshold is derived. LED control for Gate output. Thus one obtains a voltage controlled Gate additionally or alternatively to the envelope signal with voltage controlled duration.

The attack time is fixed to about 0.2 ms, the shortest decay time is about 2 ms. By changing the value of a capacitor the shortest time can be modified (details can be found here: A100_Capacitors.htm).

Typical applications: dynamic control of decay e.g. in combination with the Analog/Trigger Sequencer A-155, voltage controlled trigger delay functions (like A-162, but voltage controlled).

Voltage controlled sine-LFO with four separate, phase shifted outputs - 8HP
Notes: Module A-143-9 is a derivative of our planned thru-zero quadrature VCO. It is a voltage controlled sine LFO with 4 outputs. The phase shift between the outputs is 90 degrees. The sine shifted by 90 degrees is also called cosine, the sine shifted by 180 degrees is nothing but the inverted sine, and the sine by 90 degrees is nothing but the inverted cosine.

The frequency range is from some minutes to frequencies beyond audio with three ranges selected by a toggle switch:

- Switch position H: about 30 Hz ... 3.5 kHz with the manual frequency control ("Frq."), beyond 20 kHz with additional external CV
- Switch position M: about 1 Hz ... 150 Hz with the manual frequency control ("Frq.")
- Switch position L: about 0,1 Hz ... 10 Hz with the manual frequency control ("Frq."), down to several minutes with additional external CV

Two exponential frequency control inputs are available: CV1 without attenuator and CV2 with polarizer. Consequently the module can be used even as an experimental sine VCO but does not feature an exact 1V/oct CV input! The precision CV input will be left to the thru-zero quadrature VCO.

Two LEDs display the positive and negative share of the sine output.

The core of the module is a so-called quadrature circuit that generates a sine a cosine signal with very low distortion. The quality of the sine/cosine signals are much better than those generated by a waveform converter with a sawtooth or triangle signal as starting point.

The output levels are about 5 Vss (+/-2.5V) but can be adjusted internally by a trimming potentiometer (P5 "Shape").

Typical applications:

- External sine/cosine oscillator for the frequency shifter A-126
- Modulations with pure sine/cosine waveforms
- Quadrature/barberpole effects (e.g. with the voltage controlled mixer A-135)
- Experimental sine/cosine VCO (e.g. for FM sounds)

Many users suggested to add a common output level control, i.e. four VCAs with one common control (manual + CV without attenuator + CV with polarizer) for the output levels. This is why we also designed the Quad VCA module A-132-2 with the possibility of an internal default connection to the four outputs of the A-143-9 (no soldering required, short 10 pin flat cable with removable connectors on both ends).

The A-143-9 is also a meaningful addition for the Frequency Shifter module A-126. It enables frequency shifting even below 50 Hz generating e.g. these mellow beat sounds with a few Hz frequency shifting only. The following document describes how to connect the A-126 and the A-143-9: A126_A143_connection.pdf.

The thru zero version of the A-143-9 with temperature compensation is the module A-110-4.

Low frequency oscillator featuring 5 different waveforms - 8HP
Notes: Module A-145 is a low frequency oscillator, which produces cyclical control voltages in a very wide range of frequencies. Five waveforms are available: sawtooth, inverted sawtooth, triangle, sine and square wave.

The LFO can be used as a modulation source for any number of modules - for instance modulating the pulse width or frequency of a VCO, modulation of the cut-off frequency of a VCF, or amplitude modulation with a VCA.

A three-way switch lets you select three frequency ranges, spanning from one cycle every several minutes at the lowest, to moderate audio frequency at the highest (about 4-5 kHz).

The LFO signal can also be synchronised, via the reset input.

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.

Low frequency oscillator with adjustable waveform - 8HP
Notes: Module A-146 (LFO 2) is a Low Frequency Oscillator, which produces periodic control voltages over a wide range of frequencies.

The LFO can be used as a modulation source for a series of modules (for instance pulse width and/or frequency modulation of a VCO, modulation of a VCF cut-off frequency, amplitude modulation with a VCA).

Three outputs are available, with different waveforms: sawtooth / triangle; square wave, and positive-voltage square wave.

The waveform is continuously adjustable from rising sawtooth, through triangle to falling sawtooth. The same control affects the pulse width of the square wave.

A three-way switch can select one of three frequency ranges, spanning from one cycle every few minutes, at the lowest, up to audio frequency at the highest.

Two sample & hold units in one module for generating stepped random voltages or slicing signals
Notes: Module A-148 (Dual S&H) has two identical sample & hold modules, designed to produce 'staircase' voltages. The signal present at the sample input is sampled at a rate set by the signal at the trigger input, and held at that voltage at the S&H output.

The exact shape of the staircase depends on the sort of waveform at the sample input: NOISE or RANDOM signals produce random patterns; an LFO produces rising or falling staircase patterns.

Two LEDs for each S&H indicate the voltage (positive or negative) of the sampled signal.

Expansion module to the A-149-1
Notes: A-149-2 is an extension module for A-149-1. It makes available 8 digital random voltages (i.e. only low/high states like a gate signal). The outputs are controlled by the "Quantized Random Voltages" section of the assigned A-149-1 and correspond to the 8 digital outputs of the shift register that is used to generate the Quantized Random Voltages. As the alteration of the A-149-2 outputs is clock controlled by the Clk In of the "Quantized Random Voltages" section of the A-149-1 the A-149-2 can be used to create random rhythmical sequences.

The A-149-2 requires the A-149-1 and has to be mounted directly to the left or right of the A-149-1 as an internal ribbon cable connection has to be established between A-149-1 and A-149-2.

Two independent voltage controlled switches in one module - 4HP
Notes: Module A-150-1 (Dual VCS) contains two separate voltage-controlled switches.

Each switch has a control voltage input, a common Out / Input, and two In / Outputs. The switches are bi-directional: they can work in both directions, so can connect one input to either of two outputs, or either of two inputs to one output. Voltages in the range -8V...+8V at the O/I resp. I/O sockets can be processed by the module.

Two LEDs show which in / output is active (i.e. which is connected to the common out / input).

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.

Simple & effective voltage-controlled frequency divider - 8HP
Notes: Module A-163 is a voltage controlled audio frequency divider. The frequency of the input signal (preferably the rectangle output of a VCO) is divided by an integer factor N (N = 1, 2, 3, 4 ... up to 32). N can be adjusted manually and modulated with an external control voltage (e.g. from LFO, ADSR, Random, MIDI-to-CV, Theremin, Light-to-CV, analogue sequencer) with attenuator. The control input has polarizing function, i.e. the manually adjusted dividing factor can be modulated upwards or downwards. The basic idea of a polarizer is described in the modules A-133 Voltage Controlled Polarizer and A-138c Polarizing Mixer.

The output waveform is rectangle with 50% duty cycle. Unlike the A-115 with fixed dividing factors (2, 4, 8, 16) the dividing factor of the A-163 is voltage controlled and can be any integer value between 1 and about 20 (but only one output). In contrast to A-113 the dividing factor of the A-163 is voltage controlled and the output waveform is rectangle (the A-113 has 4 sawtooth outputs with 4 adjustable but not voltage controlled dividers).

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)

Pulse-width generator - 4HP
Notes: Module A-168-1 is a pulsewidth modulation generator (PWM Module). It derives a rectangle signal with adjustable pulsewidth from an external triangle, sawtooth or sine wave. The external signal can be an LFO, VCO or any other signal with falling/rising slopes (e.g. ADSR). In addition, the pulsewidth can be modulated by a CV signal (e.g. LFO or ADSR). The typical application is the generation of a rectangle signal with PWM from VCOs or LFOs which do not yet have this feature (e.g. A-110-4, A-145, A-147-2, A-143-4, A-143-9).

The module is equipped with these controls and in/output:

- Manual PW control (PW)
- PWM CV Input with attenuator (PWM)
- Signal input (In)
- Output with LED control (Out)
- Inverted Output with LED control (/Out)
- Internal trimming potentiometer for PW (is adjusted for symmetrical 50:50 rectangle when the manual PW control is at centre position)
- Internal trimming potentiometer for PWM range (is adjusted so that the manual PW control covers the full PW range 0 ... 100%)
- The trimming potentiometers are required to adjust the module for best operation for signals with different DC offsets (e.g. unipolar/bipolar signals) and different signal levels
- Normally the module is assigned to another module because the trimming potentiometer have to be readjusted when the input signal changes (unless the signals have nearly the same DC offset and level)

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.

Module for processing/mixing of control voltages - 4HP
Notes: A-172 is a minimum/maximum selector module and is equipped with four analogue inputs and two analogue outputs (minimum, maximum). The main application of the module is the processing/mixing of control voltages, e.g. random voltages, ADSR, LFO, S&H, ribbon CV, theremin-CV and similar, but even for audio signal processing the module can be used (e.g. several outputs of the same or different VCOs).

The module permanently picks the maximum resp. minimum voltage out of the four input signals and outputs these voltages to the maximum resp. minimum jack socket.

To adjust offset and amplitude for each input independently (i.e. to bring the signal into the right "position" with the desired level) we recommend combining the module with the A-129-3 Slew Limiter/Attenuator/Offset Generator (see patch example below). The other sketch below shows the basic principle of the max/min module by means of three sine waves (e.g. three LFOs) with different frequencies and different levels.

The module can be used also as a simple half-wave rectifier.

Modulation wheel module with two wheels - 14HP
Notes: A-174-2 is a modulation wheel module with two wheels. The factory setting is a spring loaded wheel at the left side with bipolar voltage output (i.e. 0V in centre position, positive voltage in the upper range, negative voltage in the lower range, voltage range about -5.5 V ... 0V ... +5.5 V) and a wheel without spring at the right side with positive voltage output (i.e. 0V in the lowest position and positive voltage when operated, voltage range about 0...+8 V). For the spring loaded wheel a voltage "plateau" around 0 V is preset (jumper) so that the output voltage is 0 V in a small area near the centre position.

By means of jumpers the factory settings can be changed. For each wheel two jumpers are available: one for the voltage range (positive or bipolar) and one for the voltage plateau around 0 V. If these settings are changed even the wheels have to be re-adjusted mechanically. Therefore, such modifications should be carried out by a qualified person only. By request the module is available from the factory even with two wheels both with or without springs (additional charges Euro 10.00 for each change).

Important note for module mounting: As the potentiometer of the left wheel projects about 10 mm the rim of the front panel a 2 or 4 HP blind panel has to be mounted left from the module - unless the module left to the A-174-1 has sufficient space in this area (e.g. A-174-1).

Three independent voltage sources - 8HP
Notes: Module A-176 (Control Voltage Source) provides three voltage sources, to use wherever an extra CV is required. The top two voltage sources (CV 1 and CV 2) have controls for coarse and fine control of the voltage output; the third source (CV 3) just has the one control.

The range of the voltages output can be preset, either to 0 to +5 V or to -2.5 V to +2.5 V depending on your likely requirements. There is a jumper on the circuit board for each of the three voltage sources.

A typical use for the module would be to provide fine as well as coarse tuning for an A-110 standard VCO, (which, unlike the A-111, only has one tune control).

In general, this module will be useful whenever you need a manually controllable CV on a module which doesn't itself have a built-in control.

Foot controller interface - 8HP
Notes: 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. Even a single foot switch can be used if only one gate signal is required.

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 is compatible with the foot controllers FP5 and double foot switch VFP2. The Foot controller and double foot switch are not included with the module. If you want to use another foot controller or foot switch it has to be compatible to FP5 or VFP2.

If the foot controller FP5 is used the CV output range is about 0...+8V. The gate output levels are 0/+12V in combination with the VFP2 (foot switch not operated = 0V, foot switch operated = +12V).

Theremin controller module - 8HP
Notes: Theremin module for generating a variable control voltage by approaching/removing hand to/from an antenna. The distance range is about 30-40 cm. Additionally the module is equipped with a Gate output with adjustable threshold level. Controls/Inputs/Outputs: antenna input, offset (knob for zero adjust), 2 x CV out, 2 x LED (for CV control positive/negative and zero offset adjust).

To simulate the original Theremin two A-178, a VCO (e.g. A-110) and a linear VCA (e.g. A-130 or A-132) are required. But of course the A-178 can be used to control other functions in the A-100 (e.g. filter frequency, modulation depth and/or speed, tempo, attack/decay time and so on).

The CV output voltage of the A-178 can range - according to the setting of the front panel controls - from -10V...+10V. The gate output switches from 0V to about +10V.

Applications:

- Controlling any voltage controlled parameter of the A-100, e.g. pitch or pulsewidth (VCO A-110), loudness (VCA A-130/131/132), panorama (A-134), filter frequency or resonance (A-120/121/122/123), phasing (A-125), frequency shift (A-126), resonance peaks (A-127), envelope parameters (A-141/142), tempo (A-147)

- Triggering of A-100 activities via gate with adjustable threshold, e.g. starting an envelope (A-140/141/142), Start/Stop of a sequence (A-155), any switching function (A-150/151)

- Conversion into MIDI control change messages is possible with the A-192.

If two or more A-178 are used the distance between the modules/antennas should be at least 40-50 cm. Otherwise the antennas may affect each other.

Sine converter/VC crossfader - 4HP
Notes: Module A-184-2 is the combination of two functions and planned primarily as an expansion module for VCOs or LFOs (e.g. A-110-1, A-110-2, A-145, A-147-2).

Triangle-to-Sine Waveshaper:

The upper section is a very precise triangle-to-sine converter (thanks to Tim Stinchcombe who recommended this circuit). It can be used to convert any triangle waveform into a (nearly) perfect sine. The converter is much better than the simple diode converter used in the A-110-1, A-111-1, A-145 and A-147-2. Two trimming potentiometers are used to optimize the sine shape. The converter should be assigned to one VCO or LFO because the trimming potentiometers have to be re-adjusted if the input level or DC offset of the input signal changes. If the trimming potentiometers are deliberately mis-adjusted it can be used also as a waveshaper for non-sine waveforms (e.g. sine-shaped at the top of the signal and a peak at the bottom, even voltage controlled by applying an additional voltage to the waveshaping circuit, "circuit-bending" notes will be available).

The waveform converter is DC coupled and can be used also for low frequencies (e.g. LFO triangle waves).

Voltage Controlled Crossfader:

The lower section is a voltage controlled crossfader. It has two inputs A and B. The two signals are mixed together with variable percentage. When the manual control CF is fully CCW only signal A appears at the CF Out socket. When the manual control CF is fully CW only signal B appears at the CF Out socket. In the centre position of the manual control both signal appear with the same level. In addition a control voltage input CV with attenuator is available to enable voltage control of the crossfade.

Two LEDs display the crossfading shares of input A and B.

The crossfader uses two high quality VCAs (SSM2164). Inputs and outputs are DC coupled. Consequently it can be used for audio signals and slowly varying control voltages as well.

The sockets of the upper section (triangle and sine) are normalled to the inputs A and B of the crossfader section. That way the crossfader is used to fade between triangle and sine of the VCO or LFO connected to the waveshaper. If other signals are plugged into the input sockets A and B these signals are used for crossfading.

The main application is to fade between two different waveforms of a VCO or LFO or two different VCF outputs. But the module can be used for any other signals too as the waveshaper and crossfader sections are independent apart from the normalled sockets.

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).

Eurorack phase locked loop module, featuring voltage-controlled oscillator, phase comparator & low pass filter
Notes: Module A-196 contains a so-called phase locked loop (PLL). The basic PLL system is shown in the sketch at the bottom of this page. A PLL consists of three parts: voltage-controlled oscillator (VCO), phase comparator (PC), and low-pass filter (LPF). All parts are normally connected to form a closed-loop frequency-feedback system.

This is how a PLL works: The output of the internal VCO (linear CV control, rectangle output) is compared with an external signal (e.g. the rectangle output of a A-110 VCO) in the so-called phase comparator (PC). The output of the phase comparator is a digital signal (low/high/tristate) that indicates if the frequency resp. phase difference of the two input signals is negative, zero or positive. The output of the phase comparator is processed by a low pass filter (LPF) to generate a smooth voltage that is used to control the frequency of the internal VCO. The 3 units VCO, PC and LPF form a feedback loop that works like this: The control voltage (output of the LPF) increases as long as the external frequency is higher than the frequency of the internal VCO und stops increasing when both frequencies become identical. The control voltage decreases as long as the external frequency is lower than the frequency of the internal VCO und stops decreasing when both frequencies become identical.

But there are some stumbling blocks: Different types of phase comparators with advantages and disadvantages can be made. Some phase comparators e.g. even lock at harmonics, i.e. if the two frequencies to be compared are integer multiples. But for some applications this can be used to create interesting effects. The A-196 contains 3 different types of phase comparators: PC1 is a simple exclusive OR, that even locks at harmonics. PC2 is a so-called RS flipflop and PC3 a more complex digital memory network. The user can select one of the three phase comparators with a 3-position switch. When PC2 is used a LED displays the "locked" state, i.e. when the frequency of the internal VCO is identical to the external frequency.

Special attention has to be directed to the frequency of the LPF. To obtain a smooth control voltage for the VCO the frequency of the LPF has to be much smaller than the lowest frequency of the internal or external audio signal. Otherwise the frequency of the internal VCO will jitter or wobble around the correct frequency. But for special effects this frequency jitter can be used intentionally. Example: frequencies in the range 50Hz...1kHz have to be processed with the PLL. Therefore the frequency of the LPF has to be about 10Hz or even less. Such a low frequency of the LPF causes a noticeable slew of the internal VCO. When the frequency of the external signal jumps e.g. between 500Hz and 1kHz it takes about 0.1 second until the internal VCO reaches the new frequency (like portamento). So one has to find a compromise between frequency jitter and portamento. But these remarks are valid only for the "ideal" working PLL. As the A-196 is used in a musical environment the "problems" and disadvantages with jitter and slew time lead to additional musical applications like portamento effects, wobbling frequencies or harmonic locking according to the type of frequency comparator and time constant of the PLL low pass filter. Instead of the internal manually controlled low pass filter the voltage controlled slew limiter A-171 can be used to obtain voltage control of this parameter. Normal audio filters (e.g. A-120, A-121) cannot be used for this job as the minimum frequency is to high (down to a few Hz or even less necessary) and the signal has to be DC coupled due to the low frequencies. Audio filters are normally AC coupled.

Another very important application of a PLL is frequency multiplication in combination with an external frequency divider. For this the output of the PLL-VCO is processed through an external frequency divider (e.g. A-163, A-160, A-161, A-115) before it is fed to In1 of the phase comparator. In this case the frequency of the PLL-VCO will be a multiple of the master frequency. E.g. if the A-163 is used and adjusted to dividing factor 5 the frequency of the PLL-VCO will be 5 times the frequency of the master VCO. Consequently, frequency division (A-163) leads to frequency multiplication with the PLL circuit. In combination with the PLL low pass frequency several effects can be realized (frequency multiplication with portamento or wobbling). The frequency multiplication can even be used to drive a graphic VCO. If your graphic VCO e.g. has 8 steps (e.g. A-155) and you use a frequency divider with factor 8 in the PLL feedback the output of the graphic VCO has the same frequency as the master VCO. Another application is the generation of pseudo-harmonics (not real harmonics as only rectangle waves are available) or clock generation for switched-capacitor filters.

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
