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

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

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

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

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

Notes: NANOPATCH M is a tiny and incredibly versatile patch bay, with mini jacks sockets on both the rear and the top panel. It is ideal for connecting to instruments and a mixer when used in conjunction with NANOPATCH X.

It also works with CV, so can be used as a breakout box for semi-modular synths with outputs in hard-to-reach places (e.g. Moog Grandmother) and devices that output CV over TRS sockets (e.g. MPC ONE).

Dimensions: 76 mm x 70 mm x 22 mm (not including sockets and feet)

Mini jack sockets on the back panel makes it easy to connect to eurorack systems and small instruments such as Korg Volcas.

3.5 mm to 6.35 mm cables can be used when connecting to equipment with 1/4" sockets.

Using standard eurorack cables, easily patch signals from a NANOPATCH M through effects connected to a NANOPATCH X (and back again).

How It Works

Rear sockets labelled 1/2, 3/4, 5/6 and 7/8 can be used for either mono or stereo signals. For example, if a TRS cable is plugged into rear socket 1/2, the left and right channels will break out to sockets 1 and 2 on the top panel. If another cable is plugged into rear socket 2, rear sockets 1 and 2 will correspond to sockets 1 and 2 on the top panel, both in mono.

Normalling

Channels 1-4 can be full-normalled to channels 5-8 using DIP switches located on the side of the NANOPATCH M.

This allows a signal to pass through from instrument to mixer without the need for any patching. When a patch cable is inserted into either socket of a normalled pair, the connection is broken, allowing for custom routing of the signal.

Typical Setup

A typical setup would be to have four instruments connected to channels 1-4 and four mixer channels connected to channels 5-8.

Connections to the mixer could either be made with four separate mono cables (utilizing the sockets on the side) or with two insert cables (as in the diagram).

Notes: 3xMIA is a 6-channel attenuverting mixer/offset/scale/polarizer

3 blocks of 2-channel attenuverting mixers, using dual concentric pots. Each channel can be switched to mix with the subsequent channel, allowing for 2-2-2, 4-2, 6 mix configurations.

With nothing plugged into an input, an offset is normalled to that channel. The inner knobs control the A inputs, while the outer knobs control the B inputs.

DC coupled, so it can be used for audio, CV, or both at the same time.

Notes: Module A-134-2 contains two identical voltage controlled crossfader units.

Each unit has two voltage controlled amplifiers (VCAs) with opposite control behaviour available. The outputs of the two VCAs are mixed together to obtain a common output. The behaviour of the control voltage inputs can be chosen with an internal jumper:

Symmetrical mode: If the corresponding jumper is not set both VCAs of the crossfader have the same 50% amplification with zero CV. If the applied CV becomes positive the amplification of VCA1 decreases and those of VCA2 increases in the same way. A negative CV has the opposite result. The CV voltage range to obtain the maximum/minimum positions of the crossfader is about -2.5....+2.5V. This mode is useful for bidirectional (i.e. positive and negative) control voltages, for example LFO or joy stick (adjusted to 0V CV in centre position).

Asymmetrical mode: If the corresponding jumper is set VCA2 is fully closed and VCA1 has full 100% amplification with zero CV. If the applied CV becomes positive the amplification of VCA1 decreases and those of VCA2 increases in the same way. The CV voltage range to obtain the maximum/minimum positions of the crossfader is about 0...+5V. A negative CV has no function in this mode. This mode is useful for unidirectional (i.e. only positive) control voltages, for example ADSR, ribbon controller or Theremin control voltage.

The CV input of the upper unit (CV1) is normalled to the CV input of the lower unit (CV2). I.e. if no plug is inserted to CV2 the CV input of the upper unit (CV1) also controls the lower unit.

The second signal input of the upper unit (In1B) is normalled to the first signal input of the lower unit (In2A). I.e. if no plug is inserted into In2A the signal In1B is used as the first signal input of the second unit.

As the inputs and outputs are DC coupled the module can be used for both audio and control voltage signal processing.

Notes: Great for generating random voltages from white noise, arpeggios from sawtooth waves, and downsampling audio signals.

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

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

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

Applications:

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

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

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

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

Notes: Module A-183-9 is a simple power supply for up to four devices which can be powered via USB (e.g. keyboards, smartphones). An LED shows is the +5V are present.

The module has no USB function but provides only the +5V supply for USB devices.

A control LED shows if the +5V are present.

Note: The module requires an A-100 case with built in power supply A-100PSU3. Only this A-100 supply has the required +5V available. We do not recommend the usage of an older A-100 case with A-100PSU2 as this would require the +5V adapter A-100AD5 and the max. current would be limited to 100mA.

Notes: This is a buffered/active mult with LED indicator. You get two channels of 1 to 3 multiples within a 2HP module. The output of channel 1 is normalled to channel 2 so it can also be treated as a 1 to 6 multiple as well.

Active vs Passive mults:

With a passive mult you are effectively just plugging multiple things into the same jacks. This will often cause some voltage drop in each of the signals. With an active (or buffered) mult you will not get any voltage drop from the original signal.

Comes with a black and gold panel, power cable and one year warranty.

Usage note:

The red stripe of the power ribbon cable goes towards the top of this module.

Notes: A-138s is a simple but useful 4-in-2 mixing tool. It has four inputs available. Each input is equipped with an attenuator (Level) and a panning control that is used to distribute the signal to the left and right output. Beyond stereo mixing it is equally suited to create variable parallel routings. For example: Any of the four inputs may be routed in variable intensity to feed two filters.

You may regard the A-138s as a smaller version of the A-138m Matrix Mixer.

Inputs and outputs are DC coupled, i.e. the module can be used for the mixing of control signals too.

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: Literally the size of a business card (if a little bit thicker), one of the smallest synths on the market. Simple design with a surprisingly punchy sound, plus CV and gate inputs for control.

Supplier's Notes:
The Business Card Synthesizer is a tiny synth that can be connected to a Business Card Sequencer, other synth gear, or played by itself.

Headphones can be connected directly to the output of the synth, and there are plenty of knobs to play with, so you can easily make noises anywhere. Great for learning about synthesizers!

S&H Button: Enables Sample & Hold, which disables the external CV IN jack and uses LFO1 and LFO2 to determine oscillator pitch. LFO1 sets the sample rate (SHAPE is ignored for this), and LFO2 is the wave that gets sampled.

GATE Button: Manually turns on the gate so sound comes out of the synth. This control is momentary, but you can latch it on by tapping the S&H button while holding the GATE button down.

COARSE TUNE: Adjusts the pitch of the oscillator up or down in large increments

FINE TUNE: Adjusts the pitch of the oscillator up or down in fine increments

SHAPE: Changes the shape of the wave produced by the main oscillator (VCO). Turning this control fully CW gives you a triangle wave. Start turning it CCW takes you through sawtooth/ramp, then at about the 12:00 position you get a square wave. Continue turning it CCW and you get several higher duty cycle square waves
.
GLIDE: Adjusts the rate at which the pitch of the VCO takes to go between pitches (whether changed by the COARSE TUNE knob or CV IN). Fully CCW causes the pitch to react almost instantly, while fully CW makes it take its sweet time.

LFO 1 / LFO 2 SHAPE: Changes the shape of the waves produced by the low-frequency oscillators (LFOs). The shapes are similar to those of the VCO, except that the LFOs have sawtooth/ramp waves that go both up and down (since you can actually hear the difference at LFO rates).

LFO 1 / LFO 2 RATE: Controls how fast the LFOs go.

LFO -> VCO: Routes the two LFOs to control the pitch of the main oscillator. The 12:00 position is basically "off", and the LFOs have no effect on pitch. Start turning the control CCW and LFO1 starts changing the pitch of the VCO. Maximum effect is at about 10:00. Continuing to turn the control starts to bring in LFO2 as well. All the way CCW gives you full effect from both LFO1 and LFO2.

Turning the control CW from 12:00 does essentially the same thing, but brings in LFO2 first, then LFO1.

This might seem like kind of a weird control, but it gives you quite a bit of routing flexibility with one knob. You can have no pitch modulation, LFO1, LFO2, LFO1 with a little LFO2, or LFO2 with a little LFO1.

LFO -> VCA: Routes the two LFOs to control the amplitude of the oscillator. (See LFO -> VCO control description above for more information about how the control works.)

ATTACK: Controls how fast the audio amplitude fades in when the gate is triggered. CCW is fast and CW is slow.

DECAY: Controls how fast the audio amplitude fades out when the gate is released. CCW is fast and CW is slow.

VOLUME: Controls the overall volume of the signal coming from AUDIO OUT.

FILTER: Changes the cutoff frequency of an analog low-pass filter. Turn the knob fully CW and all frequencies (that you can hear) are let through. Start turning it CCW and the high frequencies start getting cut off, until the sound becomes muddy / muffled. Use in conjunction with the SHAPE control to get the tonal quality you are looking for.

Connections:
CV IN: Accepts a 1 volt/octave control voltage to control the pitch of the oscillator. It responds from about 0-5V, but voltages outside of this range won't cause damage. The CV input is quantized, so only valid (western scale) notes are played. This input is ignored when Sample & Hold is enabled.
GATE IN: A voltage greater than about 2.5V will turn on the gate and allow audio to come out the output of the synth.
AUDIO OUT: Connect to an amplifier or another synth. The jack has both the tip and ring connected, so you can even use stereo headphones and hear sound from both ears.
Power: Connect 7.5-15VDC to this 3.5mm TS jack to power the synthesizer. The tip is positive (don't worry, there's a protection diode in case you get it reversed). You can get power from a 9V battery, AC adapter, or you may even be able to find an output on your modular synthesizer that can provide enough current.

Power connection: 3.5mm phone jack, center-positive

Notes: The MST Unity Gain Mixer adds input signals together and combines them for a summed output. For example, if you put in a 1V source and a 3V source, the output will be 4V. It's mainly used for CV, but it can also be used to combine audio signals together.

A unity gain mixer is handy in several ways:
Combining gates and triggers. Plug a few sequencer steps into the unity gain inputs, then run the output to a drum synth, VCA, envelope, etc.
Re-shaping two CV sources with a single envelope.
Combining different wave shapes or LFOs to make crazy sounds.
Controlling the CV of one source with the CV of another source. Just plug the CV out of a sequencer into and an expression pedal/touchable CV out into the unity gain inputs.

Notes: The Kontact MIC is a lo-fi theme park. It's a Eurorack microphone preamp with a piezo contact mic built into the panel.

The creative applications are endless: finger percussion/rubbing/scratching, guitar input (works surprisingly well with just a little lofi crunch), acoustic sources to CV, etc.

The PCB fibreglass has quite a nice rough texture - rubbing it with a finger or a plectrum creates quite a wide range of sounds. The back of the panel is plated to expand the surface area of the contact mic. The mic will also pick up all the physical sounds in your modular- patching, cables rustling, switches, fingers on knobs - without picking up airborne sounds i.e. the sound your modular is making. At very high sound levels will pick up vibrations from the speaker output and start to feedback.

The module will work with both DIYed contact mics made from inexpensive piezo transducers, off the shelf contact mics (often called Piezo Pickups) made for guitars and violins which you can pick up for ten bucks from Amazon or eBay or more bespoke mics like the popular Jez Riley French models (including hydrophones!) which are firmly aimed at Sound Designers.

It is an easy way to bring environmental noise and feedback into a modular system, inspired by the early days of electroacoustic music in Paris and Cologne, and by the contact microphone and phonograph cartridge experiments of John Cage, Gordon Mumma, Robert Ashley and Nicholas Collins.

Notes: The 4093 Chaos NAND Synth, in Eurorack form! The 4093 Chaos NAND Synth is a super-modifiable noise generator that will knock your socks off with its sonic potential: low pulsing drones, random robotic chaos, and high-pitched laser sounds!

A great project to begin your explorations into the world of DIY sound synthesis, the PCB was designed with the beginner in mind. Board-mountable switches, socketed IC, hands-on knobs and switches for tone control, and a detailed silkscreen PCB to help you solder components right the first time.

Notes: Synthrotek's original Mean Screamer Pedal goes way beyond a typical tube screamer clone with a couple of great mods. An original 4558 OP-AMP IC has been used to give it that beautiful classic boost.

Notes: Erica Syths Black VC EG Expander takes the Black VC EG to the next level - it outputs gates or CVs for each active stage of the envelope so you can design some really advanced patches. Inverted and bipolar envelope outputs are also available.

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 the Black VC EG. It will not work as a standalone eurorack module.

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.

PATCH POINTS
-IN (x4): Patch in any audio or CV signal to any of the 4 inputs. (NOTE: Avoid mixing CV and Audio)
-OUT: This output is the sum of the four channels

KNOBS
-LEVEL (x4): Each input has its own attenuator that allow you to bring down the level of the inputs

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

Notes: While the OD808 may have been the first overdrive circuit of its kind, it was the OD-9 that cemented this sound in the history of Rock & Roll guitar.

Looking at the OD-9's circuit, you'll realize that this is not some redesign being cleverly marketed as a reissue - this is THE original OD-9 (TS-9) circuit, yet with the addition of true bypass switching. Even the PC board is the same one that Maxon's been using for the past 30+ years, complete with empty slots where parts for the FET switching circuit have been left out!

Like the original, the current production OD-9 features the NJM (JRC) 4558D Op Amp - an essential component for authentic "TS" tone. The NJM is smoother sounding and less compressed than other Op Amps, offering superior sound quality with low noise.

The absence of the FET switching circuit gives the OD-9 some added output and a slightly more open sound than the OD808, making it perfect for the classic rock tones that it helped to define.

If your future plans include a meteoric rise to rock & roll stardom, then rely on the legendary tones of the OD-9 to fuel your ascent.

The OD-9 is a true-to-spec reissue of the legendary 1980's OD-9/TS-9 circuit, with the addition of true bypass switching for clean, uncolored tone when bypassed.

TECH TALK:

Input is fed into a 2SC1815 emitter/follower transistor to optimize the signal's impedance structure. From here it's on to the first section of an NJM 4558D Op Amp - NJM is the company formerly known as the Japan Radio Corporation (JRC) - the legendary manufacturer that designed and built tons of these components in the late 70's/early 80's.

In this non-inverting Op Amp there are diodes in the feedback loop that clip the signal gradually as well as a High-Pass filter that keeps low frequencies from being distorted as much as high frequencies - the classic "808" configuration that creates the tone we all know and love.

After this is a passive LP filter and then an active tone stage that uses the other half of the Op Amp to create a HP filter that brings back frequencies cut by the inter-stage LP filter. After the tone stage it's through the volume pot, another E/F 2SC1815 to provide a low impedance output and then the true bypass switch.

The OD-9 features Mechanical True Bypass switching via a Fujisoku 4PDT switch - input signal is sent to ground when bypassed.

Notes: The famous MS 20 filter for AE modular!

This adaptation of the filter used first in Korg's MS-20 synth for AE modular offers control knobs for cutoff frequency, resonance and CV attenuator. Two signal inputs for different signal levels control the "drive" of the module. Compared to the wasp filter this filter has a significant self resonance and also a very quick response to changes in the cutoff frequency.

The filter type is switchable between lowpass and highpass (LP/HP switch).

Notes: The 2-row rack for AE modular is 16 units wide with 2 rows; the MASTER module consumes 2 units so you have 30U remaining for other modules.

Via a joint kit (not included) another case of this width (either one-row or two-row) can be attached at a free angle; the bus is connected via a short connector cable between both cases.

The sides are made of red acrylic, all other parts are of wood fibre board (MDF), black painted.

Dimensions: 41.3 x 21.7 x 4.5 cm (width x depth x height)

Notes: Module A-115 is a four-way frequency divider. The frequency of a signal at the input is halved (half frequency = first sub-octave), quartered (1/4 frequency = second sub-octave), and so on. In this way, the DIVIDER produces four sub-octaves (F/2 down to F/16).

At the output, the A-115 produces a summed mix of the original and the four sub-octaves. There are attenuators to control the amount (i.e. Amplitude) of the original signal and each of the sub-octaves.

Bear in mind that the sub-octaves output by the A-115 are all true square waves. At the output there are always four square waves and the original signal available.

Notes: Clk is a voltage controlled clock generator with all the features a master clock needs. It has an extremely wide range from ten seconds between pulses well into audio rate. In addition, the pause button and CV input provide an expressive feature that is all too often missing in a modular setup. Stop using LFOs or other modulation sources for your master clock, and let Clk do what it's best at.

Notes: Erica Pico RND is combined LFO/random source module.

It generates sine LFO waves, white noise, S&H CV and some interesting stuff - random triggers and pulse wave with random duty circle; basically, everything, you need, to bring some uncertainty in your modular setup.

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: Erica Synths Pico OUTPUT module is just what you need to monitor your music on headphones and have standardized connection to mixing desks.
