Notes: Module A-160 is a frequency divider for clock/trigger/gate signals, designed to be a source of lower frequencies, particularly for rhythm uses. The Trigger input will take clock signals from, e.g. an LFO, MIDI sync, or the gate from a MIDI-CV interface.

At the outputs, you have access to the sub-divided clock signals, from half the clock frequency down to 1/64. The low/high levels of the output signals are 0V and about +10V.

The A-160 also has a reset input. Whenever a reset signal is sensed, all outputs are set to zero, until the reset voltage disappears.

The Clock Divider can be used in combination with the A-161 Clock Sequencer to produce stepped sequences with a length of from one to eight events.

Notes: The only module named after a Swedish botanist? Possibly. Relentless synth innovator Dave Rossum pushes the boundaries again with a state-variable stereo filter offering through-zero frequency modulation. Sounds complicated. Sounds good.

Supplier notes:
Following in the tradition of Evolution and Morpheus, LINNAEUS represents yet another Dave Rossum innovation in filter technology.

LINNAEUS is a stereo state-variable filter that provides the unique ability to linearly modulate its resonant frequency through zero into negative frequency, while maintaining stability. With extensive voltage control of nearly every parameter, Linnaeus lets you manipulate the filter's natural response curve in new ways, to create both subtle and dramatic timbral effects. And with a "one-knob-per-parameter" interface, LINNAEUS inspires sonic creativity that invites (and rewards) real-time interaction.

LINNAEUS's cutoff/resonant frequency is exponentially voltage controllable from sub-audio to ultrasonic frequencies, while its resonant gain (Q) is exponentially voltage controllable from 0dB to greater than 60dB.

LINNAEUS's channel output response characteristics are independently and continuously variable from Lowpass, through Bandpass, Highpass and Notch, to Low and High Shelving characteristics. Voltage control of the response characteristics are independently selectable for each of the two channels.

The linear thru-zero modulation is provided by an integrated modulation oscillator and/or an External Linear FM modulation input.

The voltage-controllable modulation oscillator can track the filter's exponential frequency or operate independently. The modulation oscillator's output waveform is continuously variable from Off through Sine, Triangle, and Sawtooth, to Square. The modulation oscillator output is summed with the external linear FM input and applied to the modulation index VCA, which controls the linear thru-zero modulation index from zero to 8X. The modulation index is, of course, also voltage controllable.

Notes: Erica Pico VC EG is versatile looping AD/ASR envelope generator with voltage control over attack and decay times. It has automatic Trigger/Gate detection, as well as "drone mode" - at full CW setting of the Decay knob, the envelope is full open. In the LOOP mode you can re-trigger envelopes for even more interesting modulations.

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 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.

Notes: Stereo effects processing for Tangible's affordable AE modular system. Offers a total of 15 digital effect programs with CV control over three parameters each. Can run in Eurorack via an optional adaptor frame.

Supplier notes:
The MULTIFX module offers 15 different stereo audio FX programs, a wide variety from common FX like reverb and delay to unique effects like Ring Crusher or Glitch delay. Also a nice shimmer effect is onboard.

Each program has 3 parameters that can be adjusted and additionally be CV-controlled.

With a switch the sample rate can be reduced to half the normal rate, resulting in doubling the effect times (with reverb, delay...) and introducing a nice portion of aliasing.

It is based on the FV-1 DSP chip that is well-known from other FX-modules in the Eurorack world; the MULTIFX module offers the 7 factory programs of the chip plus 8 new and unique ones created by Tangible Waves.

Notes: The LOPAG is the lowpass gate module for AE. It is based on a Vactrol (like all good lowpass gates) and has two inputs: IN (audio signal) and TRIG. A pulse on the TRIG input opens the signal path shortly and via the characteristics of the Vactrol the audio signal is filtered and attenuated in a plucked, percussive way. Additional GATE and CV inputs allow more control over the way the module works.

Notes: 4ATTMIX offers four input channels which can be level controlled / attenuated by the corresponding knobs. The attenuated signals are sent to four outputs.

Additionally, each channel can be sent to an internal mixer by the switches beside the knobs. The mix signal is then sent to the mix output.

An additional switch selects the general operation mode for the mixer, for DC/CV signals or for audio signals.

Notes: Each of the three USB-A sockets on the USBPOWER module can be used to charge your mobile phone, connect a USB lamp or supply power to any other USB device. Furthermore, the output socket provides +5V and ground to supply e.g. DIY circuits on a breadboard.

Please note: This is only a power source via USB sockets; no USB data communication is possible here.

Includes additional USB lamp!

Notes: The 2OSC/d module contains two 1V/octave hybrid oscillators. Each of them features:

- One frequency knob plus a range switch +2 octaves
- CV input (1V / octave)
- PWM input
- SYNC input
- Sawtooth/Square/Sub-octave output

The pulsewith knob controls either the pulsewidth of the first oscillator (with the second one having a fixed pulsewidth), or via a switch the second oscillator is also controlled by the pulsewidth knob. Both oscillators can be pulsewidth-modulated independently by their PWM inputs.

The module is designed as a hybrid digital/analogue module; the oscillator frequencies are determined digitally and are therefore quite stable and have a good tracking; the output wavefom itself is created analogue. It's a new idea/concept that I have implemented here; the design causes the waveform to get a bit gritty at higher frequencies (but not "digital noise") - it's the character of this thing!

Notes: 4I/O offers four minijack sockets that are connected to the AE sockets for connecting external audio sources, CV's and Eurorack modules. Sockets 1 and 3 are stereo sockets; if a stereo cable is inserted here the signal is available on sockets 1/2 and 3/4. With mono cables the four sockets can be used independently.

All sockets have an overvoltage protection (as AE modular is limited to 5V) and can be switched between audio and DC/CV signals.

Notes: This module is best if you need an oscillator for primary musical / melodic use.? It offers:



- two CV inputs 1V/octave

- Modulation input with Level-knob, switchable to frequency or pulsewidth

- PWM input

- Coarse / Fine knob for frequency

- Pulsewidth knob for square wave

- Square / Triangle / Sawtooth output

Notes: 2ENV is a dual attack - decay envelope; it can be switched between full sustain (the output remains at full level as long as the GATE input is on) and zero sustain (for percussive envelopes). Another switch (SLOW/FAST) allows selecting the time range.

For manual triggering there is a button for each envelope.

CV control: Both attack and decay time can be CV controlled; the CV "multiplies" the time by 1...approx. 8 times.

Notes: Ultra-simple 16-step Eurorack CV sequencer with randomisation option and storage for up to 16 patterns. Straight to the point business, all in just 4HP of rack space.

Supplier notes:
Small, easy-to-program sequencers are a bit of a rarity. Vox Digitalis is our answer to this issue. With intuitive displays and simple controls, VD is perfect for all your pitch CV needs. Set your sequence length, dial in each note, randomize, save and load 16 sequences -- VD does all the stuff the big sequencers do, just in 4HP.

Notes: Row Power is a clean, regulated, and protected power solution for eurorack systems. Row Power 35 provides 35W of power, suited for any typical eurorack row (84HP to 168HP):

+12V @ 1.4A
-12V @ 1.25A
+5V @ 1.0A

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.

Daisy-chain multiple Row Powers to use a single power brick for multiple rows (typically 3-5 rows per power brick). Each row will be independently regulated and protected for ultra-low cross-talk between rows. Rows can also be hot-swapped (plugged/unplugged without powering the whole system down).

Notes: Erica Pico LFO/S&H is full analogue modulations source - LFO with simultaneous triangle and pulse wave outpus and Sample and Hold - to provide some controlled randomness to your modular setup. It can also work as clock source.

Features:
Full analogue circuit
LFO with triangle and square wave outputs
Highly stable S&H circuit based on AS1100CK2 IC
Input and output protection against overvoltage
Protection against reverse PSU connection

Dimensions

Notes: Pico BBD is surprisingly great sounding (we were surprised ourselves), full analogue 4092 stage bucket brigade delay module; the smallest BBD in Eurorack. Besides nice and clean flanger and delay effects, at full CW settings of TIME and feedback knobs it can produce extreme sonic artefacts. Tweak knobs and enjoy!

Notes: Pico Mixer is simple 3 channel DC coupled mixer intended to mix audio signals and CV signals in order to obtain complex modulations. Also it may serve as CV and audio attenuator.

Features:
3 inputs
Diode protection against overvoltage

Technical specification:
Mixer gain: 1
Power consumption +4mA, -4mA
Module width: 3HP
Module depth: 35mm

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: 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: This module has 1/8" jacks to accept either mono or stereo audio signals from your modular gear.

It features input level indicator LEDs, and contains all the gain control circuitry necessary to drive external audio gear at the proper levels.

A ribbon cable is included for connecting it to either the Stereo Out Jacks 1U module, or a compatible Intellijel case with 1/4" jacks (e.g. 7U x 104HP, 7U x 84HP, or Palette 62).

Notes: Clouds, the granular synthesis module from Mutable Instruments, was discontinued in 2017. Supercell brings back Clouds in a more accessible 34 hp form factor, offering an improved user interface and several additional features:

- Each of the Blend parameters (Feedback, Panning, Mix, and Space) have dedicated knobs with their own CV inputs and inverting attenuators (attenuverters).

- The inputs and outputs now have mute switches, stereo VCAs, and separate VU meters. The knobs act as offset controls when their respective VCA inputs are patched.

- A stereo output gain control has been added, providing an additional +6 dB of gain to compensate for low output levels when using certain parameter combinations.

- The complex process of changing the sampling time and managing presets has been simplified with dedicated switches and status LEDs.

- Extensive modulation options for all parameters including direct patching of external CV, distribution of one CV to all parameters via the AUX input, or an internal smooth random CV that is normalized to any unpatched inputs when AUX is also unpatched. The attenuverters control the modulation depth in all three cases. As of firmware v1.01 the internal modulation rate can be adjusted within a range of 1 to 100 Hz.

- The inputs and outputs now include stereo VCAs and separate VU meters. The knobs act as offset controls when their respective VCA inputs are patched.

- Pitch is now controlled by two separate inputs: the V/Oct input is exponential and the Pitch input is linear. When both inputs are used, their voltages are summed.

- A manual Trig switch (for capturing individual grains) has been added, in addition to the Trig input that was present on Clouds.

All other features of the original Clouds remain intact, including access to the alternate modes. Thanks to Olivier Gillet for making the original Clouds hardware and firmware available under open-source licenses. Third-party firmware such as Parasites (by Matthias Puech) and Beat Repeat (by Julius Kammerl) will be supported in future firmware updates after the initial release of the module.

Notes: Eight channels of audio and CV sampling with real-time editing and processing. Does basic sampling well but quickly gets creative and weird.

Supplier's notes:
The 'Squid Salmpler' is a Eurorack 8 channel audio & CV sampler. It is designed for immediate real time sampling, editing and mangling within a modular context.

Taking influence from early hardware samplers, The Squid Salmple focuses on usability and instinctive operation, incorporating a proven Pamela's Workout style user interface for minimal screen dependence and a fun, hands on experience.

With support for sampling and playback for both audio and CV, as well as CV control of all parameters, on-the-fly bank loading and saving to USB, The Squid Salmple brings a unique take on old school sampling into the modular realm.

The Squid Salmple comes with a USB Stick containing approximately 90 banks of original carefully curated royalty free samples. This includes a wide range of sounds from classic drum machines and weird synths to field recordings and CV modulations. Banks are provided by both ALM and some of our favourite artists and friends including Mumdance, Solid Blake, Russell Haswell, Lauren Flax, Dave Burraston (NYZ), Sue Zuki, Dungeon Acid, Sasha Lewis and Andrew Duff.

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.

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.

Notes: The module can record the joystick movement up to a length of over a minute. The sequence remains stored in the battery-backed RAM after switching off. When playing the sequence, it can be manipulated in speed and playback direction.

There is a FREEZE function to hold the current joystick position plus an external reset input. In addition, a GATE is set during movement and a CV voltage is output as a function of the joystick movement. The ranges of the X / Y output voltages are bipolar +/- 5v or unipolar from 0 to + 10v. Both channels X and Y have a passive attenuator potentiometer, so that the voltage range can also be set lower.

Notes: Viol Ruina is an all-analogue distortion and lowpass filter with an internal envelope follower and self-modulating cutoff. The four-pole design is reminiscent of the classic filters we all know but with a completely new and slightly ridiculous twist. The independently addressable distortion circuit takes VR into overdriven paradise with a shocking amount of drive. Built-in envelope following makes an easy way to create dynamic patches with the flick of a switch, and feedback FM takes VR to a whole new realm of filthiness. Run a sound through VR, you'll get something cool out of it.

Notes: X-PAN is a compact and powerful 5 channel Voltage Controlled Stereo Mixer with Low Noise and High Headroom allowing for creation of complex panoramic audio imagery in just 10hp.

X-PAN is highly responsive to control signals allowing for exploration of the fluctuating stereo sidebands possible with Audio Rate Crossfading and Panning. X-PAN is Direct coupled for use as a CV Processing and Routing toolbox.

X-PAN consists of two full featured Channels and one simpler Channel. The top two Channels each have voltage controlled cross-fading and panning while the third Channel is a stereo aux input with stereo VCA. All three Channels are combined together at the stereo SUM outputs.

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

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.

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, colored 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% analog by amplification of the noise of a transistor. White and colored 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 colored 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 colored noise signal by low pass filtering. Consequently the settings of the controls for the colored noise (Blue, Red) affect the behavior of the random voltage! A dual color 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 color LED (red = positive / yellow = negative output voltage) indicates the stepped random voltage.

Controls:

Blue: share of the high frequencies in the the colored noise output
Red: share of the low frequencies in the the colored noise output
Rate: rate of change of the continuous random voltage
Level: amplitude of the continuous random voltage
TH/SH: switches between T&H and S&H

Inputs and outputs:

RND: continuous random voltage output (with LED display)
TH/SH: stepped random voltage output (with LED display)
Clk: Clock input of the S&H/T&H unit
C Noise: colored noise output
W Noise: white noise output

Important notes:

After power on it takes a few minutes until the two noise signals and the random signals are generated. The module is not faulty when after power on the signals do not appear immediately!

The S&H/T&H function is realized by pure analog circuitry (electronic switch followed by a holding capacitor and buffer). Consequently the output voltage drifts a bit in the holding state because the capacitor is discharged by parasitic resistors. The drift depends also upon environmental conditions like humidity or temperature.

Notes: Module A-138n is a simple four channel mixer, which can be used with either control voltages or audio signals. Each of the four inputs has an attenuator available. The output is twice available (two sockets, hard-wired like a multiple).

The module is the slim version of module A-138a and offers nearly 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-138a. The module is primarily planned for applications where only limited space is available. The only functional difference compared to the A-138a is the missing attenuator for the (dual) output.

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).

Notes: KR is based off of the concept of a guitar tonestack: you get a gnarly drive on the top and a super clean two-band shelving EQ with switchable midpoint after that. There are separate ins and outs, too, so if you want to EQ a thing and distort the other thing at the same time you can!

Kith Ruina's inspiration comes from the world of guitar amps. A drive into an EQ is an extremely common configuration for shaping guitar tone, and we find that it works extremely well for synths as well. A grungy drive into a pristine EQ gives excellent tone control, and with separate ins and outs for the two sections KR can be configured to fit into any patch you throw at it.

Notes: Fusion VCO2 is a full analogue sound source with lots of distinct features.

The core of the module is highly stable AS3340-based VCO with three simultaneously available waveforms, transistor-based suboscillator and detune function - two BBD delay lines that make frequency shifter that is mixed back to the principal oscillator in order to emulate two detuned VCOs. Tube crunch - distinct tube overdrive - is added on the top of the mix. Furthermore, Audio input mixes an external audio signal with the principal oscillator which results in crazy sonic experience. Fusion VCO2 is exactly what you need, if you wish to get really low frequencies and have a sound that sets your modular system apart from mass!

Features:
" Full analogue design
" Great tracking over 8 octave range
" Detune function for thickening the sound
" -1 oct transistor based suboscillator
" Tube overdrive circuit
" External audio input
" VCO synchronization
" Simultaneous waveform outputs

Notes: Terci Ruina combines three classic distortions in 4 hp. Distortions are reinterpreted in classic NE style and routed through each other for complete sonic annihilation of any sound. Patch in and out anywhere in the signal chain to pick the best sound for your purpose (because modular). Looking for a pretty distortion? This is probably not your module. Unapologetically gross and dirty.

Notes: Polyphony is back!

Chord v2 is a plug and play solution for bringing musical polyphony to your system. It contains four oscillator voices, a multitude of waveforms, and intelligent tuning functionality. This new version features an expanded sonic palette and feature set in half the size of the original.

It features three primary modes of operation: Chord, Free Running, and Unison. These three modes allow the oscillators to be tuned as diatonic chords, run independently of each other, or be tuned to the same internal frequency for external v/oct sequencing through independent CV inputs.

The timbral possibilities of the Chord v2 bring its polyphonic tones to life. The module ships with eight banks of waveforms encompassing traditional shapes, vocal synthesis, organ emulation, and chiptune sounds. You can also load custom wavetables using the SD card slot on the front panel.

From harmonic drones to Switched On Bach, the Chord v2 is an unparalleled addition to any Eurorack modular.

Changes from v1:

- Half the size! 14HP down from 28HP
- Eight banks of waveforms
- Full polyphonic mode
- Harmonize in minor mode
- Custom wavetable compatibility
- Expanded chord types
- Improved synthesis engine

Notes: The Spherical Wavetable Navigator (SWN) is a six-channel synthesiser that makes it easy to create slowly morphing drones, polyphonic melodies, evolving sequences, and rich textures.

The SWN features six wavetable oscillators with independent pitch, level, and waveform controls. Six LFOs (Low Frequency Oscillators) can be used as modulation sources and/or envelopes, making it easy to add dynamic motion to your patch. Each channel is a full voice and can be "played" using the top row of buttons, the internal LFOs, or note-change detection on the 1V/oct jacks. The SWN ships with 12 three-dimensional (spherical) wavetables and an easy interface which allows you to record and edit custom wavetables from live audio. Open-source software for Mac, Windows, and Linux called SphereEdit can be freely downloaded and allows you computer to create, edit, and convert .wav files into Spherical wavetables to transfer into the SWN with an audio cable.

New firmware available which adds extra features, visit https://4mscompany.com/p.php?p=820&c=5 for details.

Notes: An expander for Zadar, adding one more assignable input for each Zadar channel and manual triggers.

Notes: MISO is a multipurpose utility module, a laboratory for synthesizing control voltage signals and audio. MISO combines multiple CV tools into one module for making complex CV shapes at the output stage. The name comes from the four main functions available: Mix, Invert, Scale, and Offset.

MISO's 2 sections (1/2 IN and A/B IN) are identical. Each section has two inputs that can be used to Mix signals, Invert polarity/shape, Scale magnitude and Offset voltage. Each function can be used independently or simultaneously with the total shape summed to the mix output.

At the centre of the module is another processor, an accurate smooth linear voltage-controlled crossfader that mixes equally between the outputs of the top and the bottom MISO sections. Feed the MISOs with envelopes, LFOs, Sequences to create new shapes and then crossfade them manually or with CV using the centre section for even further complexity of shapes and animation of control signals. Crossfade between the waveforms of a VCO or audio samples with CV for more motion.

There are an endless number of ways to patch MISO with unexpected and inspiring results. MISO is the kind of module that gives modular synthesizers its incredible replay value, rewarding hours of creative explorations and its experimental and non-traditional mixing.

MISO offers a lot in a small comfortable module that matches Tiptop's system look with clean white faceplate styling. A red/yellow indicator light next to each section makes it easy to see signals and visualize polarity.

Notes: The Control Voltage Processor from Verbos Electronics GmbH is a suite of control voltage processing possibilities divided into 3 sections in a slim 18HP package. The lower 2 sections are DC coupled mixers that allow mixing, inverting, offsetting, scaling, multiplying, dividing, crossfading or a combination of these functions. The top section is a voltage controlled slewing processor with independent control of Positive and Negative slew rate, with some unique tricks. The Positive and Negative slew, or Rise and Fall rates if you like, have reversing attenuators. The slopes can be blended from linear to RC curves (starting all slides fast and ending slow, like a proper "East Coast" Portamento) without a change in speed. It can be triggered like an AD envelope and has a Gate out that goes high when the CV out is below 100mV. Of course it can loop by patching the Gate out to the Trigger in. The Bounce control adds a unique flare of overshoot to CV changes, a bit like the effect of stopping a tape reel from turning and then letting it go. The combination of multiple voltage processors offers the user the functions of analogue computer.

Notes: Module A-197-3 is a control unit for RGB LED stripes. The LED stripe is glued e.g. to the inner edges of the cases A-100P6/P9/PMS6/PMS9/PMS12 to illuminate the modules and patching statically or dynamically. Especially during live events the dynamic illumination in sync with the sound is an eye-catcher. Each colour (red, green, blue) has available a manual control for the background brightness and a CV input with attenuator that enables the dynamic brightness controlled by other control voltages of the modular system. For example three envelopes can be used which also control the loudness or filtering of sound processing modules. But even other control applications are possible, e.g. LFO, random voltages, clock/gate/trigger signals, sequencer, Midi-to-CV.

Notes: The 2hp Buff is a buffered multiple capable of splitting an input signal to multiple outputs. Due to its active architecture, inputs retain their full integrity as they are copied to multiple destinations. One input signal can be copied to six outputs, or two inputs can be copied to three outputs each. The Buff is especially great for splitting pitch or audio signals where signal integrity is critical. Keep your signals in shape with Buff.

Notes: Metron is a 16-channel trigger and gate sequencer for Eurorack with extensive functions, expansion possibilities and the tools you need to create long sequences with many variations in a very short time.

The sequencer allows pattern lengths of up to 256 steps, and the number of steps per channel can be varied to create interesting and varied rhythmic structures. These patterns can be quickly stored and exchanged between units via the SD card slot. Metron also offers a random function per step and a ratcheting function.

With the optional WMD Voltera, Metron can be expanded with four additional bipolar voltage outputs.

Notes: Scales is an 8hp dual-channel note quantizer and step sequencer. Fundamentally, it takes an input voltage, quantizes it to notes in a user-defined scale, and sends that quantized voltage to an output, where you can use it as a melodic pitch source for oscillators or any other module that expects to see discreet note values at its input.

Scales goes far beyond the fundamental, allowing you unprecedented control of the pitches and intervals hiding inside your control voltages; turn LFO's into arpeggiators; random voltages into harmonic counterpoint; and unquantized external CV sequencers into chromatically tuned note sequencers.

Quantization can be locked to an incoming trigger. There are a number of trigger output options as well, ranging from no triggering (good for pitch shifting drones); through triggers that sync with either of the two outputs (or both); to a trigger or gate transmitted in sync with one sent to the module's TRIG input.

Shift:

Scales features two independent outputs, enabling you to create shifted harmonic intervals within your chosen scale using only a single pitch input. Using the SHIFT input you can modulate changes on OUT A and/or OUT B.

You can also use the shift input to switch between scales or to change the root of any existing scale pattern or split Scales into two quantizers - each conforming to a common scale, but fed entirely different voltage sources.

Sequence:

Scales also features a 128-step SH-101 style step sequencer (complete with storage for up to 35 fully programmable patterns) - allowing you to feed OUT B with sequenced notes and rhythm patterns, while OUT A continues to function as a standard pitch quantizer for external voltages. You can even sync the sequencer to quantizer events on OUT A.

Notes: Steppy is a 4-track programmable gate sequencer with eight internal memory slots, external clocking, numerous tweakable parameters, and a performance-first design aesthetic.

Each track features numerous independent parameters that govern its playback independently of the other tracks. Specifically:

- Each track has its own length, which can range from 1-step to 64-steps, allowing for polyrhythms, fills, or constantly evolving gate interactions between tracks.
- Each track has its own gate length, which ranges from very short to very long, with tied gates possible at the extreme setting.
- Each track has its own clock divider, allowing patterns to play out over completely different periods of time.
- Each track has its own swing setting, which offsets the timing of every other step.
- Each track has its own delay setting, which offsets the timing of every step.
- Each track has its own probability control, which sets the likelihood that each programmed gate will fire when called upon by the pattern.
- Each track can be shifted (or 'rotated') forward or backward by a number of steps. So if you've created a pattern that 'feels' like it has its downbeat on step 3, you can shift that pattern two steps to the left, so that the downbeat sits on step 1.

Tracks can be programmed by entering active steps on the grid or tapped in live as the sequence is moving. Tracks can be selected and modified in real time as the sequence plays. A select button allows you to directly access each track (and each page of 16 steps within that track) directly through Steppy's intuitive multifunction buttons array.

Tracks can be individually muted and unmuted, and a special performance mode (called "Loopy") enables you to touch any two gate steps and instantly create a performance that loops between those steps.

Track patterns can be cleared without clearing its playback parameters, and all track patterns (along with their individual playback and performance parameters) can be saved as a preset to one of eight internal memory slots.

Notes: Kickall is a 6HP compact synth voice that features everything needed to make a big fat Kick sound. A stable VCO that tracks V/Oct, a couple of VCAs, envelopes for volume and pitch and an aggressive waveshaper.

The module has been designed with a kick synthesis patch in mind.

The audio path consists of a sinewave oscillator that passes across a Square Waveshaper and two VCA's. The first VCA is for the Volume envelope. The second VCA is dedicated to general volume. Thanks to his CV input, it is possible o apply accents or affects the dynamics of notes. Feeding this input with audio generates a basic AM operation expanding the sonic range of the module.

In the control path, KickAll has two envelope circuits to modulate the first VCA oscillator's pitch. Both envelopes are fired at the same time manually or via dedicated trigger input.

Through its Tune input, KickAll tracks eight octaves with high accuracy. Plug your favourite sequencer or CV source to create patterns out of the kick range, or feed it with an audio signal, for frequency modulation Fx.
