Notes: Euclid is a rhythmic pattern generator based on ideas originally presented by Euclid, the Greek mathematician. The Euclidean algorithm can be adapted to create rhythms by taking the total number of active steps in a sequence, and then distributing them across the entirety of the pattern.

This creates cyclical rhythms that are immediately musical and can be used for everything from EDM to IDM. Bring your patches full circle with Euclid.

Notes: Module A-118-2 generates the signals white noise, colored noise, continuous random voltage and stepped random voltage.

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 and Blue noise (low/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 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 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 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. Dual color LEDs are used to indicates the continuous and stepped random voltages.

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 und 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.

The level of the random voltage changes with the settings of the Blue and Red controls. Especially the Red control affects the random voltage level (which is derived by low pass filtering from the colored noise signal) because the Red control changes the share of the low frequencies in the colored noise signal. The effect of the Blue control is much smaller because it changes the share of the high frequencies in the colored noise signal which are filtered out by the low pass of the random circuitry.

Notes: Unlock the potential of the Quad LFO with the LFO Phase Expander. Each expander gives you three outputs that duplicate the LFO with a fixed phase difference. The first ranges from 0- to 180-, the second from 90- to 270-, and the last from 180- to 360-. Along with the original output, this gives you four phases of modulation. These are easily tuneable to quadrature (all knobs centred), but also any arbitrary phase relationship. You can attach up to four expanders, one for each LFO, giving you up to sixteen modulation sources.

A multiphase LFO is extremely useful for building rhythmic modulations, particularly when paired with analogue logic, such as provided by Babel. Further, regardless of the waveform selected on the Quad LFO, the output of the Phase Expander is always a sine wave. This gives you the useful possibility of having three rhythmically related phases of an LFO synced to a clock signal.

Other than rhythmic modulations, the most common use of a multiphase sine LFO is in creating panning and crossfade controls that sound correct using only one or more VCAs. This is useful in panning sounds back and forth, rotating a sound in quadraphonic space, creating Shepard tones, etc.

Even when you don't have a specific need for exact phase relationships, a multiphase LFO gives you a convenient way to expand your palette of potential modulators, adding three related but distinct waves.

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.

Notes: Two channel USB module.

Standard Mode - Send two channels into your USB device and receive two channels from USB.

Insert Mode - Send two channels to your USB device and get a copy of the sent signal in the outputs.

Toggle between the modes via a pair of jumpers on the back. The USB-B to USB-A cable is provided with the module. Why use the cutting edge USB-B? I felt the jacks were way more sturdy than mounting USB-C jacks vertically.

Expandable - Bartender, Barbacks, DVCA, Cast Iron, Mingles, and USB-2CH can all be connected with Dupont cables (aka female to female breadboard cables) via pin headers on the back of the modules. Connecting the in and out pins will send/receive the audio into the next module.

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: Analogue goodness awaits with the four-pole Low Pass Filter. Thanks to CV control over resonance and frequency, the Low Pass Filter can go from squelching leads to dynamic sweeps in an instant. In addition, 1V/Oct tracking allows it to double as a musical sine wave oscillator. Bring analog warmth to your system today in a compact, yet stand out package.

Notes: BLN is a 4 channel audio level converter designed to interface line or "pro" audio levels to modular audio levels. It features 2 independent converters with 2 channels each.

Converter 1: Line level/Balanced to Modular Level

The inputs for the top converter are for converting -10dB or +4dB signal levels (balanced or unbalanced) to +/-5V modular levels. Each channel can be set individually for +4 or -10 using channel 1 and 2 of the DIP switched

Converter 2: Modular level to Balanced Lined

The inputs for the bottom to converters accept a +/-5V modular audio level and converts them to a BALANCED +4 dB or -10 dB audio level. Each channel can be set individually for +4 or -10 using channel 3 and 4 of the DIP switched.

For balanced signals, simply use a 3.5mm TRS to 1/4" TRS Cable or 3.5mm TRS to 3.5mm TRS cable with a 1/4" TRS adapter. Unbalanced signals should use a 3.5mm TS cable

Notes: Rnd is a random voltage generator and random gate source with an internal clock.

The quantized and smooth outputs are completely independent, and each feature an attenuator to fine tune the output voltage between 0V and 10V. This allows for a musically useful range to be defined. When externally clocked, random gates erupt from the gate output.

Great for modulation and chaotic rhythmic events, Rnd is a universal solution for adding unpredictability to your system.

Notes: 6xMIX is a six channel audio (AC coupled ) mixer, channels arranged in three groups with separate outputs having led indicators. Each group can be switched to mix with the subsequent group, allowing for 2-2-2, 4-2, 6 mix configurations. The module can also be used to mix two stereo channels plus separate group of two mono channels. Perfect audio performance with the lowest noise and distortion amounts.

Notes: MIX7 is a seven channel analogue summing mixer module for Eurorack. It is designed for summing any of the different types of signals you'll find in a modular system: Audio, CV, Triggers, or Gate.

MIX7 gives ability to sweeten your mix with more headroom using the power of low noise analog summing. A compact 3HP Eurorack utility module, MIX7 is an attractive mixing addition to any rig, especially with the ability to also combine rhythms, note patterns or CV automations from different control sources. The main output of one section can be connected to the input of another MIX7 to create larger mixing groups and complex signal routes inside your modular.

The MIX7 summing mixing circuit is built with low-noise operational amplifiers, giving it an excellent sound quality for mixing audio, the beautiful texture of classic analog mixing with plenty of headroom to handle hot modular signals, and the versatility to sum non-audio signals in your system to open up new creative possibilities.

Each input is labeled with a number of dots, 1-7, yellow for input and green for output. The module matches Tiptop's system look with clean white faceplate styling.

At the back of the module is a user-configurable jumper allowing users to configure the MIX7 for either unity gain (OUT = IN) or give increased headroom (OUT = 0.4IN) for use with hot audio signals, which makes it a great pairing for Tiptop Audio percussive modules. A peak indicator light on the front panel warns the user of even the slightest audio clipping in the mix, helping to keep all the incoming sound sources at their full original quality.

Notes: MAR is a multichannel dual mixer module for the modular synthesizer. Both mixers are capable of mixing audio, CV and gate signals because they are DC coupled. MAR has two independent 4-channels mixers:

Mixer X: Is a four channel mixer with gain control for each channel. The potentiometers use logarithmic tape to have a good control with audio signals. This mixer features two outputs, the mixer output and its inverted. The output level is shown in the LED.

Mixer Y: Is a four channel mixer with gain control for the sum of the Y channels. If no jack is connected to the input Y1, the output of the Mixer X is normalled to Mixer Y. The potentiometer use logarithmic tape to have a good control with audio signals. This mixer features one output, the sum of the 4 channels. The output level is shown in the LED.

This Mixer can work as two 4-1 Mixer, or 7-1 Mixer with global gain control.

Notes: Module A-103 is a voltage controlled low pass filter with 18dB/octave slope. The circuit is based on a modified transistor ladder (Moog ladder) and is a reproduction of the legendary TB303 filter.

As for the rest the A-103 is identical to the A-120 Moog low pass filter (same controls, inputs/outputs) only the filter sound is different.

Notes: Following ADDAC System's T-Networks series, the importance of having the right input signal for firing drum modules or envelopes was realised. Gates and Triggers are often looked at as similar signals but at times it really makes a difference and results will change drastically depending if a Gate or a Trigger is fed to the input of such modules.

This led to the simple yet effective Gate to Trigger.
A four channel converter with bypass switch for each channel.

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-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 4 Channel Mixer is a basic DC coupled mixer with 4 inputs and 4 attenuators. DC coupled means that it will accept both DC and AC (Audio) signals. As with all Hungry Robot "Modular Boxes" the 4 Channel Mixer can be powered with a simple 9V DC, Negative Center power supply.

The Pico RND comes equipped with five outputs, they emit the following signals:

- Sine waves
- Pulse waves with varying width
- Random triggers
- Sample and hold material
- White noise

The speed of LFO and S&H circuit can be edited using the module's potentiometer (Range: 0.1 Hz to 20 Hz). For synchronizing the Pico RND with other gear, a clock input was implemented.

Notes: Unique, vintage reverb sound.

The SPRINGREVERB module brings the unique sound of this quite old (introduced in the 60's) technique for creating reverbs to the AE modular.

The reverb works by sending the audio signal to a set of 3 springs; at the other end of the springs the sound is picked up by a transducer, converting the mechanical movement of the springs back into an electrical signal. When the audio signal arrives at the end of the springs, the waves are reflected several times; these reflections create the reverb sound.

The spring "tank" (a metal box containing the springs and transducers, size approx. 24 x 9 x 3.5 cm) is connected externally by a cable.

The product contains all components: The module itself, the spring tank and the connection cable.

Note: The sound of a spring reverb is quite unique and has a strong vintage character; if you are looking for a more "clean", natural sounding reverb please take a look at the MULTIFX module.

Notes: The ADDAC213B is the second pair of modules from ADDAC's Eurorack Bridge system.

A pair of ADDAC213Bs can be used in standalone to send/receive 8 CV or audio signals between different points inside the same case or as an expansion to the main pair of Eurorack Bridge modules, the ADDAC213As.

Two ADDAC213B modules can be connected to each other with the use of a single ribbon cable and then used inside a case to carry signals between distant points without the need for long cables. Less clatter, less spaghetti- more space of your fingers on those knobs!

ADDAC213Bs always come in pairs. A single pair can send & receive up to 8 CV or audio signals between different points in your case at the same time. The modules can be installed in normal position or a 180 degree position to fit any need.

As an Expansion to an ADDAC213A.

Each ADDAC213B connected to the backside of an ADDAC213A adds 8 more channels to the main bridging functionality of the ADDAC213A.

Up to 2 ADDAC213B can be connected to an ADDAC213A module, expanding the bridging between two difference cases to a total of 24 channels.

If you're looking for a simple one-cable bridge between your various cases, then look no further than the ADDAC213A.

Between the ADDAC213A pair and the ADDAC213B, your cases never looked so elegantly connected together!

Each module can be installed in normal position or at 180 degrees.

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: This module offers a four-quadrant-control for CVs via its joystick.

The module can act either as CV source at its four outputs, or as four-quadrant attenuator for the CV inputs. Beyond this, a mix of the input CVs according to the joystick position is provided separately.

Another feature is a gate output that is controlled by pressing the joystick handle.

The joystick remains in each position - there is no automatic "return to centre".

The JOYSTICK module can operate in two different modes:

Quadrants independent: In this mode, all outputs are zero when the joystick is in centre position
Overlapped: In this mode, each quadrant output fades from full to zero over the whole range to the opposite corner.

Together with a quad VCA / mixer (available soon from tangible waves) you can use the JOYSTICK also for mixing/blending four independent audio sources.

Notes: ***B-STOCK: Box opened, product in perfect working order***


ADSR is a four stage linear envelope with two expressive ranges. Each stage can be modified independently allowing for the creation of complex, multi-segment envelopes. Great for modulating filters, VCAs, and oscillators.

Notes: SHTH - Sample and Hold - Track and Hold

Create stepped outputs using two different classic synthesis techniques, sample & hold and/or track & hold.

Sample & Hold

The top four jacks make up the sample and hold section. There is a noise output that is normalled to the input so you can pass a gate/trig signal into the SAMP input to get a stepped output at the OUT jack.

IN - Signal that will be sampled, normalled to NSE output
SAMP - When high updates the voltage being sent to the output
NSE - White noise output
OUT - The sampled output (freezes the value from the IN jack when the SAMP jack receives a high signal)

Track & Hold

The bottom four jacks make up the track and hold section. There is a walk signal (a randomish meandering voltage) that is normalled to the input. Track and hold is the opposite of sample and hold in that it will pass the IN value to the OUT jack until the TRACK input receives a high gate. While the TRACK input is high it will hold the value. After the TRACK input goes low, it will begin tracking the IN signal again.

IN - Signal that will be tracked
TRACK - When high the value will be held at the output
WALK - A meandering voltage
OUT - The track output (follows IN while TRACK is low, held voltage while TRACK is high)

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.

NB! This expander module can be connected only to Black VCO and Black VCO2. It will not work as a standalone eurorack module.

Notes: The Entropy Expander is a 3hp Analog Random Voltage Generator that expands upon the features of the Entropy Euroack Module. Available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

The Entropy+Expander packs together some of the most random voltage options in 6hp. It provides a controllable "Glide"(slew) out for the S/T\H, a comparator with a controllable rate("Thrsh") of random gates("Rand Gate") out with an input to compare other waveforms(Comp In, inserting a cable into here breaks the white noise normalization), and high pass filtered white noise resulting in approximate "Blue noise" (+3db/octave) and "Violet noise"(+6db/octave) outs.

The unique part of the circuit is a voltage controlled A/B switch thats normalled to the "Rand Gate" out that's switching between the S/T\H out(left Blue led window)and Infra out(right Red led window), the Glide control also effects the S/T\H coming out of the switch so you can get really random results from the "Entropy Out." Inserting a cable into "Switch CV In" breaks the random gate normalization and lets you toggle between A/B(left S/T\H out and right Infra out, indicated by the led windows) with your own gate or trigger.

There is a jumper on the pcb to select if you want glide on the s/t\h at, Entropy out, or un-slewed operation. There is also a trimmer for setting the amplitude of the incoming signal at "Comp In" which sets the frequency range of random gates. This may have to be adjusted depending on your Entropy version.

The random gate range can also be set up more as a noise oscillator by turning the pcb trim(clockwise) up or it can be set so random gates are extremely slow(trim counter clockwise) with minutes between random gates.

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.

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: Switchy is a module that allows you to turn on or off up to three modules (or busboard) independently of each other.

No need to turn off the whole case: All three voltages (+12V, -12V, 5V) are interrupted at the same time.

Used to reduce the background noise of certain "noisy" digital modules when not in use, to initialize certain modules or change their function, to change an SD card, to relieve the power supply with energy-consuming modules, etc.

Notes: AVert is a dual attenuverter. Each channel offers the ability to attenuate and invert any input signal. The signal present at channel one is normalled to channel 2, allowing for two unique output signals from a single input. Get Inverted.

Notes: Diode Chaos is a 3hp analog chaotic low frequency voltage generator Eurorack Module available as Eurorack DIY Kit, PCB and Panel, or Built Module.

It is a unique module because it has never existed as an electronic music instrument until now. The module is based on a circuit from a paper called "A simple chaotic circuit with a light-emitting diode" written by Volos, Wang, Jafari, and Kapitaniak.

Diode Chaos produces 3 phases of interrelated morphing voltages including a chaotic trigger out. The range is 20-30 seconds a cycle up to audio rate, although only the X out and TRIG out go up to audio rate. The frequency is controlled by the RATE knob. Each output exhibits different behavior at different rate settings. X,Y, and Z outs like to stay in the 4vpp range although at different RATE settings the outs can reach 10vpp. The TRIG out chaotically releases 0-10v triggers although sometimes it will spit out smaller voltage peaks.

LED soldermask windows provide constant display of positive and negative voltage crossings.

Differences between chaos and random(some quoted and summarized material from Ian Fritz's site):

Chaos is "highly irregular, but still contained within a finite region (the "strange attractor")"

Chaos occurs in 3 dimensions.

Chaos needs a non-linear element (with Diode Chaos the nonlinear element is a red LED, and the chaos is directly visible and useable at the TRIG out).

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.
