Notes: Sometimes your ears are not enough and you really need to see the sounds and control voltages you are generating. Zeroscope's two channel design lets you display and compare both control voltages and audio. It's a good old fashioned sci-fi light show!

The Zeroscope 1U is an adaptation of the excellent 3U Zeroscope by VPME.DE.

Three Modes Packed Into 1U:

- Scope: Standard graphical display, with time displayed on the X-axis and voltage displayed on the Y-axis.
- X-Y: Alternate graphical display with CH 1 driving the X-axis and CH 2 driving the Y-axis.
- Tune: Alphanumerical tuning display, which you can configure to show either Hz values or note names.

The Scope displays have adjustable display offset for each channel and an adjustable trigger threshold, while the tuner has options for reference pitch and average update speed.
Ins & Outs

The inputs are DC coupled and accept signals between -10V and +10V. The Signal on the input is normalled to the output below; this allows you to monitor or tune a signal without a mult or re-patching.

Notes: Mighty oscillations, mini size.

An analog oscillator and LFO with pure waveforms and precise tracking in a compact package. Perfect as a utility modulation source but equally capable to be used as a primary sound source. Patch it up and let it rip!

Features
Four simultaneous pure waveforms: Sine, Triangle, Square and Sawtooth
Pitch input for 1V/Oct tracking and FM
SYNC input for Hard Sync. This input has a comparator so that you can use a variety of waveforms as triggers.
Switch to select VCO (audio) or LFO range of operation
Three position Octave switch to jump pitch up or down by two octaves

Notes: This is the version II of the original uVCA.

This module was adapted from a design by David G. Dixon

Notes: Triplatt is a three-channel active/buffered attenuverter and summing mixer. Each channel has a knob, which can function as a unipolar attenuator or a bipolar attenuverter, depending on the setting of its corresponding two-position polarity switch.

Each input is normalled to a built-in precision +5V DC voltage source. With nothing plugged into the jacks, each knob controls a voltage range of 0 to +5 V or -5 to +5 V depending on the position of the channel polarity switch. Outputs A and B are also capable of a range of 0-10 / -10 to +10 when using the special function switches.

Each output is normalled to mix into the output of the channel below, making it possible to do sub mixes in groups of two or three.

In addition, each channel has a "special function" switch to alter its input voltage in a specific way. Channel A has a 2x voltage multiplier switch, allowing you to double the voltage sent into Channel A. Channel B has a +5V switch, allowing you to add 5V to whatever voltage is sent into Channel B. Channel C has a mute switch, allowing you to completely turn off the signal being sent into Channel C.

Notes: SVF 1U

Multimode State Variable Filter

The perfect 1U, multimode, voltage-controlled filter for sweet-sounding subtractive synthesis duties or to form the basis of more complex patches. Punchy, clean, and precise. Explore new sounds through the dual modulation inputs and dedicated low pass, high pass and band pass/notch outputs. This filter responds beautifully to audio rate FM and you can self-patch to get even more interesting filter responses. Adjust the Q for a sharp howl or use it as a sine VCO.

Features:

Dedicated 2-pole Low pass filter (LP) and 2-pole High pass filter (HP) outputs.
Switchable Bandpass filter (BP) and Notch filter (N) output.
Optional +6dB input boost and asymmetric clipping circuit.
PITCH input tracks 1V/Oct accurately over 4+ octaves.
FM CV input with attenuverter.
Capable of generating very low distortion sine waves from 2Hz to 20kHz when driven to self oscillation (Max Q).

Size: 20HP
Depth: 35mm
Power: 27mA @ +12V 30mA @ -12V

Notes: Outs enables your modular system to output both professional and prosumer compliant audio, and send it to external amplifiers, mixers, recording devices, or DAW interfaces. Using the L+R Level knob, it scales modular-level voltages down to the level required to drive external gear at either the +4dBu balanced professional line-level standard or the -10 dbV unbalanced standard.

Headphone monitoring is also provided via a low noise built-in headphone amp (with its own independent level control), capable of driving a wide range of impedances - from studio grade headphones to portable style earbuds.

To use Outs, simply connect the final output of your patch to the 1/8" inputs (where the built-in activity LEDs light up to indicate the presence and intensity of the input signal). The left input is normalled to the right, so you can create a stereo signal from a mono source. Or if you have an Intellijel Mixup, you can remove a jumper from its rear panel, and connect it to the Outs module using the 3-pin link cable included with the Mixup.

Notes: Noise Random Tools comprises a collection of useful utility blocks that you could use in many of your patches - Clock, Random Pulse, Analog Noise, Sample and Hold, and Slew.

Features:

- Clock and Random pulse source with adjustable rate
- Analog pink and white noise source with very accurate spectrum
- Analog sample / track and hold with very low droop
- Analog slew with adjustable slew rate

Notes: Get Amped

Amps comprises two precision linear VCAs that have been carefully designed to offer a wealth of flexibility and additional functionality. The front panel controls and signal normals allow these two VCAs to also be configured to function as: line level boosters, crossfaders, ring modulators, mixers, and much more. They can also be chained together by way of an included cable to form larger, more complex systems.

Amps features cascaded CV inputs and cascaded mix outputs allowing it to be used in a number of versatile configurations. A boost switch enables you to amplify each VCA's input by either +6dB or +20dB i ideal for boosting low amplitude signals or pleasingly overdriving audio. The addition of a phase inversion switch for the second channel allows Amps to function as a ring modulator. The CV normalization, which can also be inverted and offset, also allows for VC-Crossfader functionality.

Features

Manual LEVEL slider per VCA i convenient when using the module as a mixer, or for biasing the signal for CV (such as when modulating the VCA with a bipolar LFO).
Dedicated CV attenuators with dual color LEDs for monitoring bipolar CV signals.
Linear response curve.
Input and CV normalling of VCA A to VCA B to allow a single source to feed and/or control both VCAs.
Output normalling of VCA A to VCA B to allow both VCAs to feed a single output.
Each VCA has a boost switch that can increase the output level by either +6dB or +20dB.
Phase Invert switch on VCA B allows for ring modulation capabilities.
CV Invert switch on both VCAs allows for crossfading one signal into another.
4-pin link connectors on the rear panel allow for multiple AMPS modules to be chained together to create a 4-channel mixer; 6-channel mixer; etc.

Notes: Lovely little mono filter module in a compact desktop format. Based on the classic Prophet 5 filter, ideal for processing synths and signals, hooking up to Eurorack or other Hungry Robot modules.

Supplier's Notes:

The Hungry Robot VCF is an all analog, 4-pole low pass filter with a self-oscillating resonance control. It is a close replication of the filter circuit found on the famous Prophet 5. It uses a HM2040 which is a high quality, faithful replication of the original SSM2040 chip. This resonant filter has a beautiful tonal quality. The over-sized knobs provide a satisfying tactile response. The cutoff frequency can be controlled by external control voltage. It has a built-in attenuator and invert switch for the incoming CV. CV input does not track at 1V/Oct, but is scaled to act as a VCA when a 5V signal is applied to CV input. As with all Hungry Robot "Modular Boxes" the VCF can be powered by a simple 9V DC, Negative Center power supply.

KNOBS
-FREQUENCY: Sweeps the cutoff frequency of the filter.
-CV: Attenuator for incoming CV input.
-RESONANCE: Sets resonance of filter. Small volume drop is to be expected. Will self-oscillate at higher settings.

SWITCHES
-INVERT: Inverts the incoming CV input. Toggle to the right to invert incoming CV

PATCH POINTS
-IN: Patch Audio Signal In
-CV: CV input for Frequency. Allows for CV control of this parameter.
-OUT: Patch Audio Signal Out

Dimensions: 4.7" x 2.6" x 1.5"
Power: 9V DC - Negative Center - 2.1mm Barrel

Notes: The Hungry Robot Sample & Hold provides basic S&H functionality with some added bells and whistles. It uses an internal clock dialed into a very useful range. If the internal clock rate is not to your liking, you can bypass the Rate knob by patching a clock signal into Clk In. The Sample & Hold has a built in attenuverter giving a bit of added control over the random voltages that are outputted. White noise out for uses elsewhere. Traditionally a S&H samples voltages from chaotic white noise, but E.In allows you to bypass the white noise and patch in your own sample source (i.e. patching an LFO in for a bit crushed LFO). As with all Hungry Robot "Modular Boxes" the Sample & Hold can be powered with a simple 9V DC, Negative Center power supply.

KNOBS
-MINUS/PLUS: Attenuverter for output. Allows you to sweep between positive and negative voltage outputs.
-RATE: On board clock source ranging from approximately 25ms to 1000ms.

PATCH POINTS
-E.IN: Bypasses internal white noise as a sample source. Patch in any CV source that you want to sample from
-STATIC: Taps into white noise output (0-5V range)
-CLK IN: Bypasses internal clock with your provided external clock
-S&H OUT: Two buffered outputs of S&H voltage

Notes: You've been up all night in a bidding war on eBay to win a prized 80s rack effect unit - you can't wait to add some serious cheese to your tracks, and the sound of gated reverbs ring in your ears. Your heart pounds, and your pulse rises to crescendo as you win the auction! But there is one problem: your Eurorack system runs way too hot to simply plug straight into your stereo FX units. Your heart sinks, as you realize there is not much you can do that doesn't involve a lot of messing around with complicated and weird mono modules. That is, until now: introducing the Herzlich SFXI.

The Stereo FX Integrator was designed in response to my own need: owning several cool stereo FX units, and having no easy way to integrate them with an easy send and return, in my Eurorack system. Attenuate your Eurorack signals down to line level, or even all the way down to instrument level, and get a nice, clean boost back up to modular levels, with this dead simple and highly useful device from the R&D department at Herzlich Labs.

You can even use it to integrate external stereo line level signals into your Eurorack, which is both nice and convenient, and also useful. Finally, you have an easy way to get the sound of your JV1080 into your Clouds.

The scientists have been working overtime to produce this unit, and were fed extra rations of maize and millet gruel just to bring you this circuit. Every SFXI sold will grant the poor souls at Herzlich Labs another serving of maize and millet gruel. Please think of the poor scientists at Herzlich Labs.

Notes: HN VCF is a state variable filter having 12 db Low Pass, 12 dB High Pass, 6 dB Band Pass plus 18 db Low Pass marked as "LP!", because it has extra drive. All three parameters: "Freq", "Resonance" and "Drive" have dual knobs with outer knobs controlling bipolar CV amount. These affected CVs are then shown by the relative green/blue LEDs.

The possibility to have CV over "Resonance" and "Drives" makes it a very capable 6 HP filter.

"LP!" output has 6 dB steeper slope (18 dB) compared to ordinary 12 dB "LP" output. Plus it has much more drive.

Notes: Clever FM module that does digital-style through-zero FM using analogue circuits. Use any signals from other modules as your carrier and modulator, then phase modulate or wavefold in the FM Aid.

Supplier's Notes:
FM AID is a module designed to perform through-zero linear Frequency Modulation (FM) in the analog modular world. Any arbitrary signals can be used as a Carrier and Modulator. The module copies FM in how it is done in digital implementation, but in a completely analog circuit free of digital aliasing artifacts. Digital or software FM oscillators are mainly based on a ramp waveform which is then shaped to other waveforms. This is also represented in the FM AID module: sawtooth signal is expected on the Carrier input to give the indicated sine, triangle, sawtooth and square waveforms on the respective outputs. However the user is not limited to only use sawtooth for the Carrier and any other signal can be plugged giving many complex waveforms at the outputs.

All known FM tricks from digital implementation are also applied - you can endlessly experiment with the Carrier/Modulator frequency ratios, Modulation index (FM knob), Modulator's amplitude shaping (CV knob), feedback FM (output is fed back to the Modulator's input) and many other.
Carrier input has normalled connection to the Modulator's input. This internal routing is disconnected each time a plug is inserted in the Modulator's input. That is a handy option which allows the module to be used with only one signal source - this single signal will act as Carrier and Modulator at the same time. There won't be any frequency differences between Carrier and Modulator in this case, but many interesting wave folding sounds will be available anyway.

Technically speaking FM AID uses Phase Modulation, not Frequency Modulation. The sonic difference is that the produces sound is brighter.

SPECIFICATIONS

Carrier input level: -5V ... + 5V (can also accept inputs ranging from -1V ... +1V] to [-12V ...+12V] / [-15V ...+15V] using onboard trimmer)

Modulator input level: preferably -5V ... + 5V

CV input level: preferably -5V ... + 5V

outputs level: -5V ... + 5V

Notes: Dual xFade is a compact voltage controlled crossfader suitable for both audio and CVs. Smaller knobs set manual crossfade between A<>B, and bigger knobs are CV attenuverters. LEDs show the adjusted positive and negative CV sides for easy monitoring.

Upper inputs (section 1) are normalled to lower inputs (section 2). Thus the same signal pair A&B can be differently crossfaded in both sections.

The switch clones section's 1 controls to the section 2, which is useful to make stereo Dry/Wet adjustment or stereo VCA.

This module can be used as:

two independent crossfades

two independent VCAs

stereo crossfade or Dry/Wet control

stereo VCA

panner

Four jumpers on the back can give optional 5x amplification for each A or B input. Sot it is easy to crossfade modular level with linear level from pedals. Installed jumpers give 1x amplification, removing jumpers gives 5x amplification.

Output 1 is mixed with output 2 if left unconnected.

Notes: Mix up to four stereo channels in just 4hp, or chain multiple modules together to add channels. Inputs are normalled for mono operation. Simple, compact and high quality at a reasonable price.

Supplier's Notes:
4xSt.Mixer is 4 HP quad stereo mixer.

Notes: 3xVCA offers three high class amplifier circuits with linear characteristic. Thanks to AC / DC compatibility, a very low noise floor and basically no distortion, the module is not only a great partner for control voltages, but audio material as well. Besides a signal input and output, each VCA has its own CV input. The dual potentiometers regulate levels and bipolar CV attenuation values of all amplifiers. Using these rather unusual, yet very practical components, it was possible to equip the 3x VCA with a front panel that is only 6 HP wide. Switches allow the user to feed the results of one amplifier to the output of the next amplifier, so we can get 1+2, 2+3, and 1+2+3 outputs mix. Two-colored LEDs visualize CV and output signals.

Notes: Shapes is a wide ranging and fully analogue oscillator which can perform duties as both auxilliary VCO* as well as VC-LFO. Shapes can be configured to cycle continuously, or to provide one-shot shaped outputs. When set to one-shot mode, Shapes may be used as an ersatz envelope generator.

Using the Time knob, Shapes can cycle from as low as 8 seconds (whale song) to as high as 19500Hz (bat beeps).

Shapes has 3 simultaneous outputs:

sawtooth (+/-5V, 10Vpp)
ramp (+/-5V, 10Vpp)
triangle (+/-5V, 10Vpp)
Additional waveforms may be derived courtesy of the Shape knob. Anticlockwise from 0 achieves progressively logarithmic sawtooths and ramps, whereas clockwise from 0 achieves progressively exponential sawtooths and ramps. The effect of the Shape knob on the triangle waveform is asymmetric, anticlockwise from 0 achieves progressively logarithmic leading edge, whereas clockwise from 0 achieves progressively exponential falling edge. Progressively exponential triangle waveforms can be achieved using the Time CV knob (set Shape knob to 0) providing there is no jack in the Time CV input socket

Time CV input provides wide ranging control of time. It is possible to dial in something approaching 1V/oct over a limited range, although Shapes has not been designed to perform as an accurately tracking VCO. In the audio range, Shapes comes into its own when used as a 'daughter' VCO to an external 'mother' VCO by patching the 'mother' VCO into Shapes' Gate In input socket - some impressive oscillator sync style effects can be achieved.

Gate In can also be used to initiate waveforms in one-shot mode, where a pulse of any length will cause Shapes to complete one cycle.

*Shapes has not been designed to perform as an accurately tracking audio VCO.

Notes: The 333 is a summing and distribution module for Eurorack modular systems.

It is composed of three identical sections, the red, yellow and green, each of those featuring three inputs summing amplifier with three independently buffered outputs.

Derived directly from the CGM creative mixer series, the sum section is DC coupled, allowing the sum of control voltages as well as audio signals.

With an extremely low tolerance in both sum and output sections, it is suitable also for summing quantized voltages like the ones coming out from the quantized outputs of the SAPEL.

In case CVs or audio signals are particularly hot, the 6dB attenuator might be helpful to reduce exactly by 50% the incoming signals.

Red and yellow output are also normalled to the 1st jack socket of the yellow and green input: in this way this module can also work as a 1 to 9 buffered multiple.

Notes: The "uMM" combines a MIDI merger and two independent THRU distributors in a module that is only 4 HP wide. All sockets on the module are in MIDI TRS-B format.

At the heart of the two-input MIDI merger is a small, powerful ARM processor with plenty of buffer memory. Two MIDI streams are mixed to one output and can also be tapped via an additional second output. Two LEDs signal the operation of the merger: one LED indicates MIDI activity at the inputs, and a second LED warns of too much data at the inputs.

The second group of functions consists of two independent, separate MIDI THRU distributors. The MIDI data at the respective MIDI input can be picked up and distributed at the three THRU outputs. If required, a 1-to-5 distributor can be created from the two units by connecting an output of the left group to the input of the right group.

Features:

4x MIDI IN (TRS-B)
2x MIDI-OUT (TRS-B)
6x MIDI-THRU (TRS-B)
Powered via Doepfer connector

Notes: The C-1U module is a one-channel module for recording and playing back movements of controller. Those can be recorded with channel's knob. The movements will be output as control voltage. The record time amounts to one minute maximal.

The track can be played once only (one shot) or in loop. The speed of the play back or the output offset is controllable with the pot. There are an additional CV input for CV recordings and a reset input.

The track data remains permanently stored when a 3V battery is used to buffer the RAM. When the module is switched on, the recorded data is available again. The module can be operated unipolar or bipolar (set by jumper on the back).

Note: The C-1U KnobRekorder uses a standard 3v lithium backup battery , type CR2032. The battery is needed to keep recordings and settings stored when the Eurorack case is turned off.

Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, we did not economise on the module width, we put design and usability first. Big knobs are assigned to functions that make difference in sound. Together the Erica Black series are a range of modules that make an entire synthesizer.

Notes: Take a DJ-mixer-style combined high-pass and low-pass filter, cram it into Eurorack and you have the DJ VCF. A simple formula, but one perfected by Erica's attention to detail, with CV control and adjustable resonance.

Supplier's Notes:
As its name suggests, the Erica Synths Black DJ VCF provides sound treatment functionality typically found on DJ decks - it is fully open when the cutoff knob is set to 12:00. When turned counter-clockwise, lowpass filtering is applied and when turned clockwise, highpass filtering is applied. The filter also has a nice-sounding resonance parameter. This module provides hands-on control over the sound during the performance, as well as unconventional timbre modulations that are hard to achieve with conventional state variable filters. The Black DJ VCF is a fully analogue design and consists of two VCFs - highpass and lowpass in series and the filter management is done by complex CV routing.

CUTOFF
This is the main control of the module - manual cutoff frequency adjustment with a twist - it's fully open when the cutoff knob is set to 12:00. When turned counter-clockwise, lowpass filtering is applied and when turned clockwise, highpass filtering is initiated

AUDIO LVL
Adjust the audio signal level

RESONANCE
Adjust the resonance level manually. On settings over 1PM, the filter will start to self-oscillate. The resonance is incoming audio signal-sensitive - a signal of greater amplitude may reduce the impact of resonance on the resulting sound

CV1 LVL
This is the cuto CV attenuverter. Adjust the CV level to your taste! Notice that the cutoff CV works differently compared to conventional state variable filters - it sweeps the filter from closed lowpass through fully open to closed highpass

CV2 LVL
This is another cuto CV attenuator

CV2 IN
This is the cuto CV2 input, which is controlled by the attenuator knob

Speed : speed of the LFO, range from 0.1 Hz to +/-200 Hz
Wave (LFO 1 & 2) : 16 Syncable waveforms

The ZONE B.F. (black edition onwards) now features an additional mode. On the back of the PCB you will find two jumpers, marked as JP1. CV1 is LFO channel 1 and CV2 is LFO channel 2. By moving the jumper so it sits on one leg (rather than 2 as when you have received the module), the Sync input for either LFO channel now becomes LFO speed input, controllable via CV.

Notes: VCA 3X is a simple yet great solution for synth users looking to add more VCAs to their setup in a single and compact module. This module features 3 VCAs with individual Signal and CV inputs and outputs.

Notes: 4-input VCA stereo mixer w/ pan, stereo out, metering

Notes: Incredible sounding VCO module that helps you get incredibly rich signals out of your synthesizer. The Dreadbox Hysteria VCO features a huge frequency range of 16hZ to 32kHz. This gives you a lot of functional pitch to work with, allowing you to explore the sounds capable from this module.

The sounds themselves rest on a variable waveform selector - meaning you can scroll through the waveforms and blend them together. This can even be CV controlled, so you can obtain an evolving sound that changes over time. The modules in the Chromatic series give you a great starting point in the world of modular synths and are a must-have for beginners and professionals alike.

Notes: Module A-199 is a spring reverb module. The reverb effect is electronically simulated by means of 3 spiral springs. Spring reverb systems have a very characteristic sound that is based on the (insufficient) mechanical properties of the springs like signal delays, audio resonances, limited frequency range, acoustic feedback behaviour, sensitivity to mechanical shocks and others.

The 3-spring system used in the A-199 ensures a "dense" reverb because of the different properties of the three springs.

The A-199 implies some special features that are not self-evident for spring reverb units:

The reverb signal can be fed back to the input using the Feedback control. Even self-oscillation of the springs similar to the self-oscillation of filters is available. The feedback loop can lead even via external modules like VCA, VCF, phaser, frequency shifter, vocoder, distortion/waveshaper, ring modulator and others. In this case the reverb output of the A-199 is connected to the input of the external module(s) and the output of the external module(s) is fed back to the Ext. Feedback In socket of the A-199. This socket contains a switch that interrupts the internal feedback loop as soon as a plug is inserted.

Another feature is the Emphasis control. This enables the adjustment of the accentuation of middle frequencies (around ~ 2kHz).

With the Mix control the relation between original and reverb signal appearing at the mix output is adjusted.

Using all these features very extreme and unusual effects can be generated with the A-199.

Notes: Module A-192-2 contains two independent CV/Gate-to-Midi/USB interfaces. For each of the two sub-units these inputs are available:

- Gate Input (min. +5V)
- CVN Input (defines the Midi note number), 1V/octave standard, range 0...+10V (i.e. 10 octaves)
- CVV Input (defines the velocity value assigned to the Midi note message), can be used alternatively for Midi volume (CC#7), range 0...+5V
- CVC Input (free assignable to any Midi control change number), range 0...+5V

For both sub-units a common CV Transpose input is available (1V/octave, range 0...+10V). The voltage applied to this input is added internally to CVN before the Midi note number is generated. It can be used e.g. to transpose two sequences simultaneously by one voltage.

How it works:

Whenever the rising edge of the Gate input is recognized a Midi note on message is generated. The note number corresponds to the sum of the voltages applied to the CVN input and the common CV Transpose Input that is present at the rising edge of the gate signal.

Notes: USB/MIDI to clock interface that allows for synchronizing clock-driven modules with the MIDI environment. It processes only the Clock, Start, Stop and Continue MIDI commands. It has several clock divider outputs, each one start, stop and reset outputs for controlling sequencers and also an interesting wait function. Input is either a 5-pin DIN socket or USB.

Notes: A-180-9 is another simple but useful tool. It can be used to connect up to 14 signals between different cases by means of standard network cables (RJ45). These cables are available all over world smoothly in different lengths and colours. From the factory two black network cables with 0.5 m length are enclosed.

The upper network connector is wired to the eight sockets 1-8, the lower to the six sockets A-F. That way it's possible to pre-patch different cases and connect signals, that are required in all cases (e.g. clock, start/stop, master CV) by means of one or two cables only instead of 14 individual patch cables. When only eight signals are required only the upper network connector is required and the sockets 1-8 are used. When more than eight signals have to be patched both network connectors have to be used. It's also possible to wire the upper and lower network to different cases (i.e. signals 1-8 to external case #1 and signals A-F to external case#2).

The module is fully passive (no power supply required) and simply wires the 14 sockets to 14 pins of the network connectors.

The A-180-9 comes in pairs for combining two modular systems.

Notes: Module A-174-4 modules outputs three control voltages generated by a spring-loaded X/Y cross potentiometer (so-called joy stick) and a Gate signal. The control voltages for X and Y are controlled by the X and Y position of the joystick in the usual way. The third control voltage Z is controlled by the rotation of the spring-loaded joystick knob. The Gate signal is generated by a button at the center/top of the joystick knob.

For each control voltage the non-inverted signal (X, Y, Z) as well as the inverted signal with adjustable offset (-X+XO, -Y+YO, -Z+ZO) are available. The generic joystick control voltages are bipolar, i.e. they range from typ. -5V (lowest position) via 0V (center position) to typ. +5V (highest position). The "Overlap" switches can be used to add a fixed offset voltage of typ. +5V to the non-inverting output in question so that the output voltage range changes to typ. 0...+10V (rather than -5...+5V). That's necessary if e.g. a VCA has to be controlled, which requires a pure positive control voltage range. The switches are named "overlap" because they allow the overlapping of the non-inverting CV output (X, Y, Z) with the inverting output (-X+XO, -Y+YO, -Z+ZO) for crossfading applications. With the overlap switch "on" and appropriate setting of the offset control it's possible to obtain a control voltage range of 0...+10V for the non-inverting output and +10V...0V (i.e. same range but opposite direction) for the inverting output.

The offset voltages which are added to the inverting outputs can be adjusted by means of three small potentiometers. That way different kinds of control voltage ranges are possible, e.g.
-5V ... +5V for the non-inverting output and +5V ... -5V for the inverting output ( Overlap = off, Offset = 0)
0 ... +10V for the non-inverting output and +10V ... 0V for the inverting output ( Overlap = on, Offset = max)
-5V ... +5V for the non-inverting output and +10V ... 0V for the inverting output ( Overlap = off, Offset = max)
0 ... +10V for the non-inverting output and +5V ... -5V for the inverting output ( Overlap = on, Offset = 0)
On top of this the four quadrant voltages Q1, Q2, Q3 and Q4 are available. A quadrant voltage becomes positive when the joystick is positioned in the quadrant in question.
Each CV output is equipped with an LED that displays the present voltage.

Because of the construction height of the joystick (about 7 cm) the module cannot be installed into the cases A-100P6, A-100P9, A-100PMS6, A-100PMS9 and A-100PMS12 during transportation as the depth of the case cover is not sufficient. Into the base cases A-100PB and A-100PMB as well as in all other cases without cover the module can be installed without problems.

Notes: Module A-171-2 is a voltage controlled slew limiter with a lot of additional features beyond a simple slew limiter. It's mostly a licensed copy of Ken Stones VCS which is in turn based on the Serge VCS.

Typical applications:

- VC Slew Limiter / VC Portamento / VC Low Pass Gate:

Cycle switch = off, no trigger signal applied to Trig socket: Voltage controlled Slew limiter or portamento generator: the signal applied to the signal input is "slewed". The slew up and down times are controlled manually by means of the Up and Down controls, the effect of the CV Up and CV Down control voltages are controlled by the CV Up and CV Down controls, in exponential mode these controls also affect the slew shape (see symbols at the CCW and CW positions of the controls).

If an audio signal is applied an short slew rates are chosen the module works as a simple VCF/VCA combo.

- A/D Envelope Generator / Pulse Delay / Subharmonic Generator:

Cycle switch = off, trigger signal applied to Trig socket, no input signal: Simple Attack/Decay envelope Generator, the rise and fall times are controlled like the slew up/down times above, including the shape of the falling/rising slope of the envelope, the exp. CV input can be used to change both attack and decay simultaneously.

At the End output a pulse appears as the end of the envelope is reached (less than about 20mV), this can be used as a pulse delay.

If a series of triggers are applied to the VCS faster than the total rise and fall times, the module will divide the incoming signal by a whole number. In the audio range the output will be the sub-harmonic series.

- VCLFO / VCO:

Cycle switch = on, no trigger signal applied to Trig socket, no input signal: Voltage controlled LFO/VCO, the rise and fall times of the waveform are controlled like the slew up/down times above, including the shape of the falling/rising slope
the exp. CV input can be used like the CV input of a VCO or VCLFO, the response is exponential but not exactly 1V/oct.

Notes: Module A-160-5 is a voltage controlled clock multiplier. The incoming clock signal (socket Clock In) is multiplied by a factor that depends upon the control voltage on socket CV In (0...+5V) and the position of the Mode switch. The multiplied clock signal is available at the socket Clock Out. According to the position of the Mode switch different clock multiplying factors are assigned to the control voltage. With 0V CV no clock output is generated. This state is indicated by "all LEDs off". With increasing CV integer factors (left position of the mode switch), power of two factors (middle position) or a mix of both (right position) are obtained. Nine LEDs are used to show the currently selected multiplying factor. In addition two LEDs are used to display the incoming and outgoing clock signal.

A manual control is used to adjust the clock multiplication factor manually without the need of an external control voltage. The voltage generated by this control ("Manual") is normalled to the CV In socket. As long as no plug is inserted into the CV In socket the clock multiplication factor is adjusted by means of the manual control knob and displayed by the LEDs. For dynamic applications (like the ratcheting function described below) the manually generated CV is overwritten by the external CV which has to be fed into the CV In socket.

The module can be used for all kind of clock multiplying applications. One important example is the generation of so-called ratcheting sequences. The band Tangerine Dream is famous for this kind of sequences. A normal sequencer generates only one gate signal per step. A ratcheting sequence may have also more than one gate pulses per step. This function can be obtained by using the A-160-5: one CV output of the sequencer is used to define the number of gate pulses per step. If the control of the step in question is fully CCW the generated CV is 0V and no gate signal is generated (mute of the step). When the control of the step in question is turned clockwise one, two or more gate pulses are generated depending upon the position of the mode switch and the voltage generated by the CV at this step.

Technical note: Due to the nature of clock multiplying it takes a few input clock pulses until the clock output is stable. One has to average a few input clock pulses to generate the multiplied clock output signal. Even when the input clock frequency changes it will take a few cycles until the output clock signal is correct as the module cannot foresee the future of the clock input signal. The generated clock output signal is derived from the last few cycles of the clock input signal. Consequently the module should be driven only by a clock signal with constant or slowly changing frequency.

Notes: Module A-160-2V is an enhanced version of the standard clock divider A-160. The module is a frequency divider for clock/trigger/gate signals, designed to be a source of lower frequencies, particularly for rhythm uses.

The Clock input will take any digital signal from, eg., an LFO, MIDI sync, or the gate from a MIDI-CV interface. At the outputs, you have access to three sets of seven different sub-divided clock signals, from half the clock frequency down to 1/128. The low/high levels of the output signals are 0V and about +10V.

The A-160-2V also has a reset input. Whenever a reset signal is sensed, all outputs are set to certain levels which depend upon the selected mode.

Notes: Module A152 is a very useful switching and T&H module. It combines a voltage addressed 1-to-8 multiplexer and 8 fold T&H that can be used as kind of an analogue shift register too. The active in/output is displayed by a LED. The digital output of the currently addressed step outputs "high". The remaining digital outputs are low.

Instead of voltage control even clock/reset controlled addressing of the active step is possible. The rising edge of each clock signal causes an advance to the next state. The rising edge of the reset signal resets to step 1.

The sum of the voltages coming from the manual Address control and the CV input define the currently addressed step of the 3 sub-devices. If the module is controlled by clock and reset the control voltage has to remain unchanged as the CV control has priority over the clock/reset control (e.g. simply turn the CV control fully counter-clockwise and do not touch the Address control knob).

Sub-device #1 is the bidirectional 8-fold multiplexer (kind of an electronical 8-fold rotary switch). Bidirectional means that it works into both directions like a mechanical rotary switch: the common socket may work as an output that is connected to one of the 8 inputs that are e.g. connected to modulation or audio sources. But the common socket may even function as input. In this case the signal applied to the common socket is output to the currently addressed single socket. The voltage range of the in/outputs to be switched is the full A-100 voltage range -12V....+12V. All A-100 signals can be switched without any restrictions.

Sub-device #2 is the addressed 8-fold T&H. The signal at the common T&H input is connected to the addressed T&H output. As soon as a new output is addressed the last voltage is stored at the output (Track&Hold function). The T&H section of the A-152 allows the emulation of the "toggling T&H" function of the Buchla module 266 "Source of Uncertainty". Only the first two T&H outputs of the A-152 are required for this application. This unit can be used also as kind of an analogue (shift) register. The difference to a "real" analogue shift register is that the sampled output voltages are not shifted to the next output but remain allocated to the same output. But in some cases (e.g. controlling the pitch of 3 VCOs by 3 output voltages of the A-152) the result is the same.

Sub-device #3 is the digital output section. The digital output of the currently addressed turns to "high". All other digital outputs are low. The digital outputs can be used to trigger e.g. envelope generators or to control the reset input in the clocked mode to reduce the number of addressed stages.
