Notes: Reverse-engineered from the original machine, our BD909 is an identical recreation of the original all-analog drum circuit of the TR-909. We've added additional controls and synthesis features that turn this classic circuit into a chest-pounding analog bass drum laboratory - all tightly packed into an 8HP module. The BD909 sound differs from our BD808 in that the main sonic energy is centered in the mid to low frequency range (as opposed to the low frequency range of the BD808). This frequency range gives the needed headroom allowing your bass Lines to deeply fill up the low end while the kick drum rides on top - creating a clear and punchy mix.

The BD909 includes all the controls found in the original: Attack, Decay, Tune Decay, Accent and Level. We have gone beyond that and added controls that further increase the palette of sound this circuit is capable of. First off, we've added a tuning control knob for the oscillator and included its own CV input and attenuator that let you tune your 909 kick with your bass lines. Next, we added control knobs for the tuning attack and extending tuning decay - each one affects the other, allowing for very intuitive and interactive sound shaping - this feature opens up numerous "sweet spots", and provides the ability to center the energy peak at different parts of the sound. Finally, we offer additional punch and distortion by giving complete control over the internal waveshaper, which allows you to overload the waveform manually or with voltage control.

Beginning with the classic and pure sound of the 909 kick, these additional functions greatly expand the BD909's flexibility and let it create powerful analog bass drums that range from soft and smooth to punchy and aggressive - and everything in between.

Control signal inputs and associated attenuation controls allow for voltage control of signal levels. Control inputs are normalised to 5v thus providing manual mix control in the absence of control signals.

Notes: Samara is a "Swiss Army Knife" type of module, intended to serve the most common voltage and audio signal processing purposes such as attenuation, offsetting, mixing, inverting, and even basic waveshaping. Samara features four channels, each with two inputs and an attenuator, additional switchable offset generators, four voltage level and polarity indicators, two adders with switchable scale, and a precision four-channel processor that selects minimum and maximum voltage.

Notes: ***B-STOCK: Box opened, product unused & in perfect condition***


This has two LFOs, each with variable waveshape from Saw to Triangle to Ramp waveforms, or variable Pulse width on the Square wave output. LFO 1 has the addition of a low range and a Sync input. The nominal maximum frequency of the LFOs when in Triangle shape is 20Hz, but under certain combinations of settings they will go much higher, well into audio range.

Also included is a DC coupled VCA, the input of the VCA is normalised to the output of LFO 2, so a 0 to +5V input to the VCA CV input gives control of the LFO waveform amplitude. It can also be used as a stand alone VCA.

This module is very useful for controllers such as the Waldorf KB37 where the modulation wheel gives out 0 to +5V, this can be routed to the VCA CV module so the level of the modulation waveform can be easily controlled. This makes it very easy to add VCO vibrato or filter 'wah' with control of modulation amount from the modulation wheel or other controller.

Notes: The Shifty is essentially a combination of four sample and hold stages, a sequential gate and sequencer controller. This collection of functions allows for some specific and useful utility application.

One of the primary uses for Shifty is to take a monophonic sequence source and route each new note of the sequence to up to four different synthesizer voices in a specific pattern. In this way you can create pseudo polyphonic sequences since each voice can be triggered to play and sustain while the next voice int the sequence gets triggered. Another term for this is hocketing.

The other main application of the Shifty is to function as an Analog Shift Register. In this mode each new gate input received causes the current set of pitches to be shifted to new output locations as a new one is added and the oldest one is replaced. This can be an interesting way to create chords that are up to four stacked notes when used with a pitch sequence source that has a harmonious series of notes (e.g. a pentatonic scale works really well). Even just using two of the outputs will yield very interesting melodic interplay and is an excellent way to make a simple sequence much more complex and interesting.

In a more basic way the Shifty could be used as a simple Sample/Track and Hold module or as a sequential gate.

Notes: The Quad VCA is a compact and feature packed module that is sure to find its way it almost all of your patches. In addition to being used for standard VCA duties it can also be used as a mixer and signal booster.

Features:

- Manual LEVEL control per VCA which is convenient when using the module as a mixer or for biasing when CV modulating the VCA with a bipolar LFO.
- Dedicated CV attenuators with dual colour LEDs for monitoring bipolar CV signals.
- Continuously adjustable response from linear to exponential per VCA.
- Each CV input is normalled to the adjacent one for cascaded control.
- Each output is normalled to the mix input of the adjacent one which allows you to use adjacent sets as submixes or the fourth output can be used as a master mix output when none of the other outputs are patched.
- Each VCA has a boost switch that increases the output level by approximately +6dB (double).

Notes: The Sampling Modulator is a multi-function module that lies somewhere between a VCO, a Sample & Hold, and an 8 step trigger sequencer.

Sequencer Clocked Sample & Hold

In this mode it acts like a regular Sample and Hold (S&H) but since it is "sequencer clocked", it is capable of much more interesting patterns than the usual S&H melodies.

The CLOCK input can work in two ways: 1. As a typical clock 2. In "positive going hard sync" mode allowing you to create shuffling and polyrythmic effects.

The HOLD input can be used to keep certain notes playing.

Analog Down-Sampling Effect

In this mode (with the clock running at audio rates) you can go from nasty and harsh sampling rate reduction to an almost clean signal. (The clock run up to 25Khz without external CV and up to 200Khz with CV on the input).

Sampling Modulator/Shaper

Thanks to the V/Oct clock, by feeding a simple waveshape such as a sine wave to IN, and pitch CV to the VCO as well as to the Sampling Modulator CV input, their related frequencies and aliasing caused by the sampling rate reduction are capable of creating clangorous metallic sounds, 8 bit textures and much more.

The game becomes much more interesting when you try to destroy the wave by flipping on and off the switches of the sequencer (which at times can make it sound like three VCOs running in unison).

To understand how the Sampling Modulator works, keep in mind that we are working with a temperature compensated ramp core VCO with more than 4 octaves of tracking. This allows the timbre to stay the same while you move through the scale as the internal and external VCOs are synced in a fashion similar to "frequency related sampling rate modulation"

Unusual V/oct VCO You can use the trigger outputs as a pulse VCO. Flipping the switches on and off the switches can offer a lot of interesting timbral changes.

Notes: Module A-112 is the combination of a voltage controlled 8 Bit Sampler and a wavetable oscillator. On top of it the module is able to generate some special effects. A-112 was designed as an additional sound source with the typical sounds of the early 8 bit samplers and is not comparable with the modern polyphonic MIDI samplers available on the market.

Sampling mode: 8 bit audio resolution, 128kB memory in 2 banks 64kB each (equivalent to 2 seconds of sampling time for each bank with 32 kHz sampling rate), audio input with attenuator, overload display in record mode (gate LED), possibility of MIDI Dump to store sounds in a computer via MIDI, non-volatile memory for the 2 samples in the module, manual tune control for adjustment of sampling rate for record and play, CV input (~ 1V/Oct), both manual tune and CV determine the sampling rate respectively the pitch (pitch range is 5 octaves), gate input (not a trigger: the sample starts at the positive edge of the gate signal and is played as long as gate is high or until the end of the sample is reached), manual Gate button, non-filtered audio output (thus quantizing noise can be used as an element of the sound intentionally).

Wavetable mode: special appearance of the sampling mode when playing a sample, the audio input is now used as a second control voltage input for moving through the sample in 256 byte wide loops (wavetables). The control voltage required to move through all wavetables applied to the input "Wave CV In" is in the range -2.5V (wavetable 1) ... 0V (wavetable 127) ... +2.5V (wavetable 256) when control "Atten." is set fully clockwise. To achieve the typical wavetable oscillator sounds the sampling memory must contain corresponding wavetable data (e.g. loaded via MIDI dump). These data contain a set of wavetables with different harmonic content (e.g. a filter sweep) to get the typical wavetable sound while moving through the tables via CV. But you may also use a "normal" sample and go through the sample with CV to obtain partially amazing sounds never heard before. You may use for example sampled speech and go with CV through the syllables or speech shreds to get really very extreme sounds. An ideal addition for this feature is the Offset/Attenuator module A-183-2 which can be used to adjust the position of the wavetable (Offset) and the modulation depth (Att.). The corresponding jumper of the A-183-2 has to be set to bipolar offset (as the A-112 requires -2.5V...+2.5V to pass through all 256 wavetables). As modulation source an LFO (A-145, A-146, A-147, A-143-3), ADSR (A-140, A-141, A-142, A-143-1/2) or a random voltage (A-118, A-149-1) may be used. Even a ribbon controller (A-198 or R2M), the Theremin module A-178, the Joystick A-174 or the Wheels module A-174-2 are useful to drive through the wavetables.

Effects: Additionally, the module offers - in a way free of charge - some effects like delay, reverse delay, pitch shifting or freeze. But it has to be pointed out that due to the 8 bit audio resolution these effects are not comparable to high quality effect units and should be understand as an extra for nothing. The A-112 is not an effects unit!

The sampling time of the A-112 is about 1...30 seconds corresponding to a sampling frequency range of about 60kHz...2kHz (64kB@60kHz ~ 1 s, 64kB@2kHz ~ 30 s).

Technical note: the module uses a battery for the non-volatile storage of the sampling data. Batteries have a limited lifespan and have to be inspected at least every two years. For details please refer to the FAQ page of our website: Lifespan of rechargeable batteries (used for memory backup).

Notes: Tallin is a dual voltage controlled amplifier (VCA) with overdrive, offering some unusual control features and a range of attractive tonal characteristics. Each of the two identical channels offers two simultaneously available inputs for voltage control over signal attenuation or gain, with linear and exponential response to CV. Volume control knobs offer manual gain settings ranging from fully closed (-80dB) up to +18dB. A colour LED indicator displays output signal levels. A soft-clip circuit avoids harsh clipping distortion, while a switchable overdrive circuit offers two carefully crafted distortion responses, simulating the sound of classic tube amplifiers.

Since both CV inputs are simultaneously active, they can be jointly exploited within patches featuring more complex volume control that otherwise would require using two traditional VCAs in series. As the signal path is DC-coupled, Tallin can also be used for handling the control voltages.

Notes: Sewastopol is a multifunction Eurorack module designed for easy interfacing of external gear to your modular environment. It can export line and professional level audio, import audio from instruments and electroacoustic transducers, and analyse the incoming audio to generate voltages and triggers to control your modular system.

This is a second, vastly improved revision to the original 2014 Sewastopol, featuring a completely redesigned preamplifier circuit, better ergonomics and various other improvements.

Notes: Clep Diaz is a handy and small step CV and LFO generator. In step and random modes, use the encoder to control the number of steps in the sequence; in LFO mode, the encoder controls the amplitude of the wave. Toggle the directionality of the sequence: up, down, or up/down to customize the CVs further. CD also gives CV control over the number of steps in the sequence and an end-of-cycle trigger output. Unipolar and bipolar outputs allow maximal control.

Notes: A-105-4 is our first polyphonic filter and contains four
identical 24dB Lowpass filters (SSM2044 type). It has
available common manual controls and CV inputs with
attenuators for these parameters:

Frequency (F)

Frequency Modulation Intensity (FM)

Resonance (Q)

Audio Input Level (L)
Each filter has available a separate FM input as well as an Audio Input and Output. The FM input is typically connected to the output of the associated envelope generator (e.g. A-141-4).
The envelope amount for all four filters is controlled by the FM knob and the CVFM input by means of four built-in VCAs, which are controlled by the FM control and CVFM input. This allows also voltage control of the envelope amounts.

In addition common frequency modulation for all filters is possible (e.g. by an LFO). For this the CVF input with attenuator can be used. The range of the audio input level control (L) allows also clipping/distortion with typical A-100 audio levels
(e.g. from A-111-4) at the filter inputs. Even this parameter is voltage controllable as well as the resonance (Q).
Application: polyphonic patches (four VCFs with same parameters).

Notes: Erica Synths Cymbals is a distinct topology digital/analogue module, where cymbal samples are passed thru AS3330 based VCA and controlled via envelope generators of unique design. The module features 10 sets of custom Crash and Ride cymbal samples with Tune control and individual Decay control. Accent and CV control over Tone and Decay allow you to create lot of variations in the Cymbals track. An extra feature is sample looping - when it's on, a certain part of the sample is looped while the envelope decay is on, thus creating a distinct, delay-like effect. Cymbal samples are developed by producer and musician Nero Bellum.

Notes: The original MiniMod Glide +Noise module was based exactly on the original Minimoog Model D circuitry, which was designed to be used with the built in Model D keyboard, and because of its vintage design its range was severely limited to 5 or 6 octaves, and it also responded to positive voltages only. Another limitation was that it would not return fully to zero when selecting long glide times, which restricted the range even more.

So we made the decision to re-design the MiniMod Glide + Noise using modern precision parts, and we have come up with an all new circuit which has exactly the same function, but with a hugely extended range. It has the same Glide slope characteristic (a slightly curved Linear Glide) as the Model D on which the MiniMod is based, however in response to many requests from customers we have adjusted the glide up and down speeds so that they are now very similar , which is much more useful in real world applications that the earlier MK1 version which (like the Model D) would glide up considerably faster than it would glide down.

The new Mk2 MiniMod Glide Noise module now has an impressive 14 octave range, and can respond to negative voltages down to -5V. This is a very useful feature, as our MiniMod VCO's will respond to negative control voltages and produce correspondingly low frequencies; so it is now possible to glide down quickly or slowly to crazy sub bass levels! The hold feature has been improved too, it covers the full audio range as well as DC control voltages, and works as a track and hold module with Eurorack signal levels.

A further enhancement is that the Mk2 module can now (using selectable jumpers) transmit or receive pitch CV to the Eurorack power bus; for example, the Glide CV Output can now be directed to the Bus in order to send CV's to (for example) three VCO's via the bus without the need for a passive multi and four patch cords!

The Noise section of the module is unchanged, except that we have slightly boosted the level of the Red Noise output to bring it more in line with Eurorack control voltage levels.

Lastly, it is much shallower - Mk1 Glide Noise had a depth of 54mm, and it was the only MiniMod module that was too deep to fit a skiff style case - and this prevented a full MiniMod system being installed into a shallow Eurorack case. The new MK2 version is only 28mm deep, so this allows both it and a full MiniMod system to be mounted into shallow skiff style Eurorack cases.

Dimensions: 6HP wide, 26mm Deep
Current draw: 36mA Positive, 38mA Negative

Notes: The Listen Four is a four channel stereo mixer with line, modular, and headphone outputs. Two mono channels with Pan knobs and two stereo channels with dual inputs provide optimal compatibility with both stereo and mono signals. The Listen Four can be daisy-chained to other Listen modules to create a larger mixer with sub-mix outputs.

Notes: The Listen Four Quarters is a four channel stereo mixer with 1/4" (6.35mm) TRS balanced outputs and 1/8" (3.5mm) headphones output. Two mono channels with Pan knobs and two stereo channels with dual inputs provide optimal compatibility with both stereo and mono signals. The Listen Four Quarters can be daisy-chained to other Listen modules to create a larger mixer with sub-mix outputs.

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: 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: 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: 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: Versatile stereo digital filter based on Endorphin's Grand Terminal module. CV-controlled cutoff, resonance and separate high-pass filter. Simple but effective.

Supplier notes:
The Squawk Dirty To Me is a stereo filter with voltage controlled resonance. It features eight filter modes and zero-delay feedback.

- Simple and effective 6hp stereo VCF
- 8 filter modes available with meta CV scanning, famous zero-delay feedback Grand Terminal filters
- Additional hi-pass filter in series quickly cuts the boomy low end

- Special control scale: exponential scale in the range from about -20dB to -80/90dB, linear scale from about -20dB to 0dB
- Remark: this special control scale results in a loudness behaviour that is a bit different from pure linear or exponential VCAs
- Out: audio output of the module (= VCA output)

Envelope:

- Gate (socket): Gate input (min. +5V), can be normalled to the bus gate signal by means of a jumper
- Att: manual control for Attack
- D/R: manual control for Decay/Release
- Env. (switch): used to switch between A/D, ADSR and A/R mode of the envelope generator, in centre position (ADSR) the sustain level is fixed to about 50%
- Envelope (socket): envelope output (about +10V)
- CVT (socket): CV input for time control, by means of two internal jumpers one can select which time parameters are controlled by the CVT input (e.g. A only or D/R only or A/D/R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question)
- Envelope LED display
- Attack time range: ~ 1ms ... 5 sec (can be extended by using the CVT input)
- Decay/Release time range: ~ 1ms ... 15 sec (can be extended by using the CVT input)

Notes: Back in 2008, the original Z5000 was not only the world's first Eurorack DSP effects module but also the first Tiptop Audio module released. It brought voltage controlled digital effects to Eurorack for the first time and the Z5000 was eventually replaced by the Z-DSP open source platform. Now, years later with over a decade of experience developing audio effects for Eurorack signals we are introducing a totally new version of the Z5000: a compact stereo 8HP multi effect with voltage controlled parameters, VC analogue clock generator driving the DSP chip and 24 of our creme de la creme reverbs, delays, modulation, harmonization and pitch modulated effects. A number of programs in the Z5000 combine more than one effect, in series or parallel, that represent studio techniques from-the early days till modern times often leaning toward the more experimental side.

Notes: The window comparator is a very useful circuit building block that is common in general electronics, but rarely found in modular synths. While a regular comparator activates when the input signal voltage is higher than a threshold level, a window comparator checks if the voltage is between two levels (these form the 'window').

Compare 2 combines two such comparators and a logic section in 8 HP. The result is an advanced tool for extracting gates and pulses from analogue signals in Eurorack synths.

The detection windows are defined by the shift and size parameters, which can be varied using the knobs and CV inputs. Complementary gate outputs are available, with big three-colour LEDs showing each comparator's status.

All inputs are normalised from the left section to the right, but the two comparators can also be used completely independently. On the bottom, the outputs from both comparators are combined in various ways by the logic section, which also features LEDs.

You'll find a use for this truly multi-functional module in practically any patch, processing either CV or audio: complex rhythm generator, dual pulse width modulator, frequency multiplier/divider with PWM, digital ‘ring modulator’ with PWM, dynamic depth VCO synchronizer, voltage controlled swing, logic function array with adjustable thresholds... and many more applications waiting to be discovered!

Notes: While modular synthesisers are most often used as stand-alone instruments, they also present exciting opportunities for processing external signals. Anything from an electric guitar to an effects send on a studio mixing desk can benefit from the unique sonic capabilities of even a modest Eurorack system.

However, patching in an external source usually requires an adapter cable and plenty of clean gain to bring the signal to Eurorack level. If the signal source is balanced, a balanced input is required as well to provide the best possible interference rejection.

Receive 2 (or RX2 for short) provides a convenient all-in-one solution. It offers two universal external inputs, which accept both balanced or single-ended signals via XLR or 6.35 mm jack connectors.

The circuit incorporates low-impedance design practices, radio-frequency (RF) filtering and premium balanced receivers to provide transformer-like interconnect performance in a compact and affordable module. And thanks to the electrostatic discharge (ESD) protection, it’s rugged enough to survive the rigours of performing on the road.

The very clean integrated pre-amps feature variable gain, ranging from unity to +40 dB on each channel. As a result, Receive 2 can handle just about any signal source you may encounter, including electric instruments, piezoelectric pickups and many dynamic microphones.

Adjusting the gains is a breeze thanks to the dual peak-responding LED meters. A mix output is included as well, so external signals can be easily mixed directly in the module.

Notes: For decades, the voltage controlled slew limiter has been a staple of modular synthesisers. With its extreme versatility, it can be used to slew control voltages (CVs), create envelopes, as a low-frequency or audio oscillator and much more.

Today, Contour 1 brings a fresh approach to this classic circuit. It delivers much improved performance and control by incorporating modern design techniques.

At its most basic, a slew limiter slows down the rate of voltage change in a signal. On Contour 1, the rising and falling rates can be individually set using sliders and CV modulation.

The gate and trigger inputs allow the module to be used as a function generator: create snappy attack-release (AR) and attack-decay (AD) envelopes, with slope times ranging from 500 us to 30 seconds. The dedicated gate input makes it easy to generate +10 V envelopes from any signal source. Using the large tactile push button, AD envelopes can be manually triggered. A trigger will also reset the output voltage.

When set to loop mode, Contour 1 will continually re-trigger itself. In this mode, it fulfils the role of a variable-shape low-frequency oscillator (LFO) or temperature-stable voltage controlled oscillator (VCO) in the audio range.

Both the rising and falling slopes can be individually bent, from concave through linear to convex. While doing so, the deviation in slope time, and thus oscillation frequency, is kept to a minimum. Since the bend parameters are separately voltage controllable, boundless modulation possibilities present themselves.

Explore anything from shape-shifting envelopes to rich VCO timbres: Contour 1 will make you re-think what a slew limiter can do.

Notes: The "uMCLK Divider" module can either work as a MIDI clock divider or as an analog clock divider. The divider outputs are assigned differently in both operating modes.

After receiving a MIDI start command, the module works as a MIDI clock divider. There are fixed dividers on 11 outputs. Via the divider output KEYS, triggers can be triggered and mixed via MIDI notes. The keyboard zone extends over three octaves. With the help of the LEARN key, the receive MIDI channel and the lowest note of this 3-octave range can be defined.

When stopped (i.e. after receiving a MIDI stop command or after switching on), the module works as an analog clock divider and divides the analog clock present at the CLOCK input. The 12 analog divider outputs can be reprogrammed via SYSEX. Ready-made SYSEX files are already available (e.g. for even / odd dividers, Fibonacci series, offbeats, etc.). The RESET input resets the analog counters or serves to deactivate the analog divider.

Notes: The A-143 series of modules contain multiple modulation sources. Module A-143-2 is a four-fold ADSR type envelope generator. Other modules of this series are the Complex Envelope Generator A-143-1 (Quad AD) and the Quad LFO A-143-3.

The module contains 4 independent ADSR-type envelope generators. Each sub-module has available the controls Attack, Decay, Sustain and Release. The three-position Range switch allows to select the desired time range (low - high - medium). The adjustable envelope time ranges from several minutes to some milliseconds. On top of this each sub-module is equipped with three digital outputs (high/low): "End of Attack (EOA)", "End of Decay (EOD)" and "End of Release (EOR)". As soon as the criterion is valid (e.g. end of decay state) the corresponding digital outputs turns to "high". These outputs can be used e.g. to daisy-chain several ADSR sub-modules. For this the digital output in question (EOA, EOD or EOR) has to be connected to the Gate input of the following ADSR. Even automatically running envelopes (pseudo LFOs) or so-called "quadrature envelopes" with cyclical modulations of several ring-shaped, daisy-chained ADSRs are possible. To obtain a pseudo LFO simply the EOD or EOR output has to be connected to the Gate input of the same ADSR.

In addition to the obligatory Gate (G) input for envelope generators each sub-module has available a Retrigger (Rt) input. The retrigger turns the direction to "upward" if the envelope has already reached the decay state while the retrigger pulse occurs. If the envelope is still in the attack phase the retrigger input has no meaning. This a different behaviour from A-140 and A-141!

The Gate inputs of the units 2, 3 and 4 are normalled to the Gate input of unit 1, i.e. Gate input 1 is connected to the switching contacts of the Gate input sockets 2, 3 and 4. Thus one Gate signal applied to Gate input 1 can be used to trigger all four sub-modules simultaneously.

The envelope outputs are displayed with LEDs.

The maximal envelope voltage (Attack/Decay reversal point) is about +8V.

If voltage control of all parameters is required module A-141 is available.

Notes: Row Power is a clean, regulated, and protected power solution for Eurorack systems. Row Power 45 provides enough power for two to three typical Eurorack rows (typically up to about 312HP):
+12V @ 2.0A maximum, 1.5A recommended
-12V @ 1.4A maximum, 1.2A recommended
+5V @ 1.5A maximum, 1.2A recommended

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. For custom power systems, the Row Power 45 has a set of easily soldered holes for using large gauge wire or MTA156 connectors to connect to distribution bus boards.

Multiple Row Power modules can be powered from a single power brick by daisy-chaining with an inexpensive barrel cable. The Row Power 45 can also be daisy-chained to 4ms Company's Pod enclosures. Each power supply is independently regulated and protected for ultra-low cross-talk between rows/pods.

The Row Power 45 is compatible with the 4ms Row Power Shield. This device (sold separately) attaches to the back of the Row Power 45 and monitors the amount of current being drawn, as well as the voltages of the power rails. The information is sent over Bluetooth to be displayed on a phone or tablet.

Notes: The Looping ADSR is an extremely versatile envelope generator. It can act as a traditional ADSR envelope requiring a gate signal to activate or as a looping ADSR. Envelopes can be output with both linear and exponential curves. In Loop Mode it repeats the cycle of Attack, Decay, & Release. Once the Release phase is complete, it loops back to the Attack and begins the cycle again. The Looped envelope can be further manipulated with the Loop Scale knob. Loop Scale shrinks the overall size of the envelope while keeping the ratio of A:D:R identical. All knobs on the Looping ADSR have CV input. As with all Hungry Robot "Modular Boxes" the Looping ADSR can be powered with a simple 9V DC, Negative Center power supply.

KNOBS
-ATTACK: Sets the attack length (1st stage of ADSR cycle). Determines how long it takes to come to full voltage after gate is applied (up to 10 sec.)
-DECAY: Sets the decay length (2nd stage of ADSR cycle). Determines how long it takes to go from full voltage to sustain voltage (up to 10 sec.)
-SUSTAIN: Sets the sustain level. Determines what voltage the envelope returns to after decay stage
-RELEASE: Sets the release length (Final stage of ADSR cycle). Determine how long it takes to return to 0V after gate is released (up to 10 sec.)
-LOOP SCALE: When in loop mode, this knob scales down the length of the envelope while keeping the ratios identical

SWITCHES
-LIN/EXP: Selects the envelope type: linear vs. exponential curve
-LOOP/ADSR: Switches between Loop and ADSR mode. LOOP turns the loop on. ADSR is a traditional ADSR requiring a gate signal
-RPT./GATE: Works only in LOOP mode. RPT. automatically repeats the loop without a gate. GATE mode requires a gate to begin looping.

PATCH POINTS

Notes: Designed with versatility in mind, the Fold 6 is a six-stage wavefolder with simultaneous series and parallel outputs, dual signal inputs and voltage-controlled folding and overdrive shaping.

Supplier's Notes:
Often considered to be the opposite of filters within a modular system, wavefolders are designed to fold a signal over itself multiple times. This generates additional harmonics, resulting in rich timbres.

While there is a bewildering array of filter types within the synthesiser world, most wavefolders fall within only a few categories. Diode wavefolders in particular come in just two variants: series and parallel circuit topologies. Choosing a specific folder also means being limited to specific sounds and capabilities.

For the first time, Fold 6 puts forward a 6-stage hybrid series/parallel topology, yielding a greater sonic palette than ever in just 4 HP. Having both main (series) and alternate (parallel) outputs means a single module now gives access to just about all wavefolding tones imaginable.

To take things even further, an integrated symmetrical soft clipper limits the output signals to approximately 10 Vpp, keeping the amplitude within typical Eurorack levels and making it easier to create overdriven sounds at high fold ratios. This clipping stage can be driven continuously using the shape parameter, smoothly transforming the folded waveforms into pulse waves for even more harmonic content.

Two signal inputs are included, to mix audio signals or add in a DC voltage for asymmetric folding. The symmetry can also be manually controlled using the dedicated knob. Of course, both fold and shape parameters feature voltage control, to enable continuous timbral modulation.

Moving beyond simple signal processing, Fold 6 also lends itself perfectly for feedback patching, CV folding or frequency multiplication; its modest size belies the sonic capabilities within.

Notes: Sono Abitus is a high-quality output module. It has a stereo pair of Eurorack-level 1/8" inputs that feed a pair of 14" TRS jacks for line output and a 14" headphone output.

Notes: 10HP Edges Clone with integrated midi interface and PSImidi which allows any TRS midi cable to be used.

MIDI Functionality:

MIDI Learn: Press this button and send a midi note. The device will use that channel as the base channel

MIDI Mode: This button cycles between two operational modes.

1. 4 single voices trigger on 4 midi channels starting on the base MIDI channel (i.e. base channel is channel 2 so the voices are mapped over channels 2, 3, 4, 5)

2. Simple Poly mode where each voice plays on a different note on the same midi channel

Note about MIDI and Gating: The gate is normalled OPEN by the Gate 1 input. This is by design but will also force the gate open when the device is triggered by midi. Placing a dummy jack will break the open normal the gate will trigger via MIDI normally

Basic Usage instructions:

Front:

Voltage Select switches: Independent for each channel. Does NOT affect MIDI/I2C data

Slider LED color: To change the LED color, simply remove the cap and rotate the square LED 180s. Do NOT force the LED back in, it should slide in easily, may require wiggling.

Rear:

Power Header: Standard 10pin power cable, there is NO polarity for this connection. It can be connected either way

MIDI Out Header: This is a 4 pin header but only 3 or 2 connections need to be used. To connect to a DIN cable, either GND, 5 (to pin 5, current sink/aka -), and 4 (to pin 4, current source/aka +) should be used. For internal module to module connections, only pin 4 and 5 should be used. The ground pin is only for the shield in a midi cable, it is never connected on a midi input and isnt necessary for the short module to module lengths

I2C Header: 3 pin header to connect to other I2C devices in your rack, this is an unbuffered connection so cable lengths should be as short as possible (20cm/6" recommended). There are 4.7k pull up resistors on this connection

Module Orientation jumpers: There are 3 of these jumpers which determine how the module operates depending on if the jacks are on top or bottom. They will come installed in the position matching your panel but can be changed should you want to flip it. "INV" is Jacks on Top, the white position is jacks on bottom. Changing these jumpers will change the numbering of the faders from left to right (1->8) in both MIDI and I2C and will invert the voltage response (i.e. 10->0V from top to bottom). The jumper is shown in the "jacks on top" position in the pic below. ALL THREE JUMPERS MUST BE IN THE SAME POSITION for the module to operate correctly.

Module Config DIP switch: This allows you to switch between I2C Follower and I2C Leader modes easily. Simply move the switch to the "lead" position and restart the module (you can press the blue reset button once). The other 3 positions are for future expansion and not currently implemented.

Connector for Expander: This connects the F8R to the I/O expander. The cable is attached to the expander. Note the keyway at the top of the part, the connecter will ONLY connect one way

Notes: This is 2 x opensource branches. The input of channel one is normalled to all other inputs so you can run this as 1 to 4, 2x 1 to 2, etc. Dual Color LEDs on sliders
