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.

Notes: The CVx 1U expander module has eight user-configurable outputs and connects to the MIDI 1U module. Using the Intellijel Config app, you can assign each of the eight jacks to generate just about any type of voltage that can be derived from a MIDI signal; pitch, gates, triggers, clocks, velocity ... you name it! You can chain up to four CVx modules to a single MIDI 1U to add a whopping 32 additional channels of midi control to your modular.

Each CVx module can also allow you to generate 2 or 4 voice polyphonic controls with selectable voice allocation modes. The connectivity, feature set, expandability, and compact size make the MIDI 1U + CVx system ideal for integrating your modular gear with the rest of your rig.

Intellijel's MIDI 1U system comprises several elements, which work together to provide flexible, programmable MIDI-to-CV conversion to your Eurorack modules: The system comprises two mandatory components, and one optional component:

MIDI 1U module - This 14HP 1U module receives MIDI from an attached, external MIDI input connector (7U case, Palette case, or MIDI IN Jacks 1U module), and extracts (by default) Pitch, Velocity, Mod, CC, Gate, Trig, Clock and Reset messages - sending the proportional voltages to individual 3.5mm jacks for patching.If desired, the CC and MOD jacks may be configured to respond to either Channel Aftertouch or High Resolution CC, and the Reset jacks can be configured as a Run jack, instead. Additionally, MIDI 1U features an alternate Dual Mode, which maintains the Clock & Reset functionality, but uses the other six jacks to transmit Pitch, Velocity and Gate messages derived from two separate MIDI channels.

MIDI input connector - the MIDI 1U module does not have its own MIDI input jack. This enables you to use the MIDI/USB inputs built-in to your Intellijel 7U Performance Case or Palette Case. If you don't own one of these cases, you can purchase the MIDI IN Jacks 1U module to connect an external MIDI device.

CVx 1U module - This optional 14HP 1U module connects to the MIDI 1U module and adds an additional eight 3.5mm CV outputs. These outputs are fully programmable using the Intellijel Config app, and greatly expand MIDI 1U's ability to control your entire Eurorack system.

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: Designed to be a highly customizable connection matrix, 3DVCA packs a boat load of utility into a small 6HP package. Four VCAs share the three macro controls: X, Y, and Z. As a group, they shape incoming and outgoing signals and emulate the coordinates of a point in 3 dimensional space. This allow the VCAs to work together in a mono, stereo, or quad configuration and accomplish a variety of mixing, crossfading, and panning functions.

3DVCA is designed to be used in the following functions:

Quad monophonic crossfader
Dual stereo crossfader
Stereo balancer
Stereo VCA
Mono to stereo panner
Unity mixer with up to eight inputs
Quadraphonic panner

Each output has a dedicated SUM input which allows an external signal to be automatically mixed into the output signal. This allows 3DVCA to daisy chain both with other mixers and other 3DVCAs. For example, you can create a full mono, stereo, or quadraphonic mix by plugging the output of each 3DVCA into the sum inputs of the next 3DVCA in the chain. Using this method, a set of 3DVCAs can create a fully voltage controlled and decentralized mixer which ties together anything from a small skiff to a monster synth.

When 3DVCA works as a crossfader or panner, the X and Y parameters follow an equal-power curve that keep output signals at the same volume no matter how many inputs are mixed together. This is in contrast to the Z parameter which follows a linear curve to always behave predictably with external modulation sources. All inputs are fully DC coupled in order to work with modulation speed signals as well as static DC voltage sequences; this means that 3DVCA can handle any sort of signal that you throw at it. All op amps in the device employ rail-to-rail inputs and outputs to enable the largest headroom when mixing many different signals together.

Whether you need to maximize your mixing functionality in the smallest possible footprint or have the most control over every aspect of your system, 3DVCA provides a ton of functionality in any system. Enter a higher dimension of sound with the Mystic Circuits 3DVCA.

Notes: Module A-147-4 is a dual voltage controlled LFO (Low Frequency Oscillator). Each LFO has the five waveforms triangle, sine, rising and falling sawtooth, as well as rectangle available. The rectangle output features manually adjustable pulsewidth and pulsewidth modulation by means of an external control voltage. The core waveform is triangle. The other waveforms are derived from triangle by means of waveform converters. The frequency of each LFO can be adjusted manually and modulated by means of an external control voltage with associated attenuator and polarity switch. By means of a jumper the basic frequency range of each LFO can selected: about 0.02 Hz (~ 50 seconds) ... 2.5kHz or about 0.0017 Hz(~ 600 seconds) ... 220Hz. That way each LFO can be used also as a VCO with a max. frequency of about 2.5kHz. Each LFO features a reset input which can be used to reset the triangle signal.

The module has these controls and in/outputs available:

Control F : manual control of the frequency, for each LFO the frequency range can be selected by means of a jumper from two values (see technical notes)

frequency coverage of control F in the high frequency range: about 0.075 Hz (~ 13 seconds) ... 1,4kHz

frequency coverage of control F in the low frequency range: about 0.007 Hz (~ 140 seconds) ... 125Hz

Control CV: attenuator for the signal applied to the CV socket, by means of a jumper a small positive voltage can be applied to the switching contact of the /CV/ socket, as long as no patch cable is connected to /CV/ socket the CV control then works as fine control for the frequency

Switch CV Pol.: polarity switch for the signal applied to the socket /CV/

Control PW/PM: combined control for manual and CV control of the rectangle pulsewidth:

when no patch cable is connected to socket /P/ the control is used to adjust the pulsewidth (PW) manually

when a patch cable is connected to socket /P/ the control works as attenuator for the external CV signal with a basic pulsewidth of 50:50.

Socket /CV/: frequency control voltage input, in the factory the module is adjusted so that the sensitivity of this input is exactly 1V/octave when the CV control is fully CW.

Socket /R/: reset input, according to the associated jumper the reset input is edge triggered or level controlled (see technical notes for details)

Socket /P/: pulsewidth control voltage input

Sockets with waveform symbol: output of the waveform in question (triangle, sine, rising and falling sawtooth, rectangle)

The output voltage ranges are about -5V ... +5V (10Vpp), except the rectangle output

For the rectangle output one can choose by means of a jumper if the range is about -5V ... +5V or 0...+10V.

LED: visual control of the LFO (triangle)

The inputs of the module are labelled with white characters on black background (in the text included into two slashes). The outputs are labelled with black characters.
Technical notes and special features:

The basic frequency range of each LFO can be selected by means of a jumper. The settings correspond to two different capacitor values for the VCO circuit. The relation between the two ranges is about 1:11. When the upper range is selected frequencies from about 0.02 Hz up to 2.5kHz can be generated. For the lower range the values are about 0.0017 Hz ... 220Hz. To obtain these full frequency ranges external control voltages are required. With the frequency control F only the frequencies mentioned above are possible.

Apart from that the range for the manual control F can be reduced to obtain a finer resolutuion. For this a jumper has to be removed. The range of control F is then reduced to about 1:4.5 only.

In the factory the starting voltage of the triangle output after a reset is adjusted to 0V, i.e. the triangle starts from 0V with the rising slope after a reset. By means of a trimming potentiometer the starting voltage can be adjusted to another value (e.g. to -5V).

Another jumper is used to set the reset behaviour to edge triggered or level controlled. When set to edge triggered the rising edge of reset signal is used for the reset (independent of the duration of the "high" state of the reset signal). When set to level controlled the triangle output remains at the starting voltage as long as the reset signal is "high". Only when the reset signal turns "low" the triangle starts.

Notes: Flexible Eurorack signal paths under gate or trigger control: that is the basic principle behind Route 4. Consisting of a pair of complementary routing sections, it grants access to a new level of signal routing options.

The module's top section is a 4-to-1 router. Any of the four signal inputs may be selected to be mixed into the section's output, as determined by the control inputs.

Control can either be gate or latch driveniin the latter case, the signal inputs are toggled on and off by received trigger pulses. Meanwhile, the solo/multi switch determines whether the inputs are exclusive, or if multiple may be active at the same time.

With each input socket biased by a +1 V precision voltage source when left unused, gate or trigger controlled transposition of pitch sequences becomes a breeze.

On the bottom, the 1-to-4 router provides the same feature set, with a single input being routed to up to four outputs and normalisation between the sections adding some patching convenience.

All signal paths are designed for use with any Eurorack signals, whether they be control voltages, audio or gate streams. Visual feedback is provided by 10 responsive LEDs, continually displaying the status of the routers.

With Route 4, an 8 HP super-flexible analogue mixing and routing powerhouse has arrived to fuel your patching imagination. The ability to redirect signals within a modular system on the fly, with an unparalleled level of control, is sure to excite even the most seasoned patcher.

Notes: Arkan

Dual Voltage Polarizer

You may have heard this before: "You can never have enough VCAs". A voltage polarizer (also known as a bipolar VCA or a 4-quadrant multiplier) is often viewed as the VCA better suited for CV. As it can be used as a unipolar VCA and it allows you to invert a signal when it is modulated with a negative voltage. Resulting in interesting movements in your modulations.

What sets Arkan apart from other voltage polarizers is the curvature control, a feature usually only seen in unipolar VCAs. By taking a different approach to the classic voltage polarizer circuitry, Malstrom have devised a unique solution that provides a new way to shape your audio and CV. The non-linearity of the polarizer also makes Arkan really good at reaching silence when presented with a 0V CV signal.

At audio rate, Arkan acts as a ring-modulator with four controls to change timbres.

Boosting adds odd harmonics (symmetrical distortion), while offsetting adds even harmonics (asymmetrical distortion). The modulation curve changes ring modulation sharpness, and modulation strength determines the carrier dominance.

Two identical channels with carefully selected features will make Arkan your go-to modulation control hub. Arkan is especially useful for common utility duties such as mixing, scaling, inverting and offsetting. As well as CV modulation, feedback patching, and waveshaping. All this makes Arkan a very versatile tool that will certainly have a place in your patch!

Features (per channel)

- Input attenuation with inverter switch gives you more precision and range, with voltage inversion and quick silencing.
- Bias input with attenuverter control to offset your input signal or mix/invert another signal.
- CV input with curvature control allows you to shape the polarizer and improve its 0V attenuation.
- CV modulation control to fade in the modulator, allowing you to determine the amount of modulation.
- Voltage gain and polarity led indicators showing you exactly what is happening under the radar.
- Output normalled internally and externally (to other Arkans) to easily mix signals.

Additional features

Optional signal boost (x4 / +12dB) via switch on the PCB to increase voltages when needed.
5V or 10V voltage reference selection for bias voltage and CV input range to adjust Arkan to your system.

The Erica Synths Black BBD is one of kind analogue delay module. It features two BBD lines: short, 1024 stage and long, 4096 stage, that work simultaneously and you can smoothly fade between those two, thus creating distinct multitap effect.

Furthermore, an advanced BBD clock noise cancellation circuit is implemented that reduces unwanted BBD noise without filtering higher frequencies of audio signal. Most of parameters are voltage controlled, which allows to integrate the module in complex modular setups.

Time

This is delay time manual control.

Because of BBD clock suspension circuit, delay time can be pushed in extremely long regions, however in that case BBD clock noise may appear. The Time CV is added to the knob setting.

In level

This is the input attenuator switch. Select among full amplitude, half amplitude and audio off.

BBD mode

This control smoothly fades between short and long delays. Any setting in-between will result in distinct multitap delay effect.

LFO rate

Adjust the internal modulation LFO rate. The internal LFO controls delay time, and it's automatically disengaged, when an external modulation signal is connected. The LED gives visual feedback on the LFO rate.

LFO shape

Select the LFO shape. Three shapes are available - triangle, square and in-between shape - mix of triangle and square.

Input

This is the audio input of the module. This is manual Dry/Wet mix. The MIX CV is added to the knob setting.

Colour

Even though the module has BBD clock suspension circuit, the colour switch provides extra lowpass filtering of the signal. At top setting no filtering is applied, at lower settings increasing filtering is present.

Feedback

This is the delay feedback manual control. In extreme clockwise settings the module goes into self-oscillation, and by adjusting delay time and BBD mode settings, the module becomes a drone machine. The FBK CV is added to the knob setting.

CV level

This is the Time CV level attenuator. If nothing is patched into TIME CV socket, it controls the internal LFO amplitude.

WET out

This is the WET signal output of the module - use it for advanced patches.

Out

This is the main output of the module.

Notes: Erica Synths Fusion Dual Mixer is designed to mix and overdrive audio signals on the vacuum tube.

Use the Fusion Mixer as two independent 3-input mixers (also for stereo signal mixing) or a 6-input mixer. Special feature of the Fusion Mixer - great tube overdrive effects when level knobs are set to 3 o'clock or above. When used with drum machines, it even emulates sidechain compressors. When used to mix signals from VCOs Fusion Mixer it works as waveshaper, especially, if pulse width modulated pulse signals is used in one of inputs.

All Fusion modules by default are configured to work with regular eurorack PSU.

Due to the fact that cold tube heaters have lower resistance, Fusion modules have significant power consumption peak at startup, when power consumption almost doubles for 1-2 seconds. This is not a problem with linear PSUs that have power inertia, but may cause switching PSU internal protection to turn off power supply. Please make sure your PSU has some headroom before installing multiple Fusion modules.

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

Notes: 8HP Tides version 2

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

Notes: 6HP Micromodule of MI Warps.

Notes: Delta-V is a fully analogue dual-channel function generator, featuring a dedicated VCA and LFO cycle switch for each channel. It packs a great deal of functionality in only 10HP, and will surely find use in almost every patch.

Generate envelopes, slew gates and signals, or run LFOs with precise control over attack and decay times. Using the SHAPE knob, Delta-v can create a wide range of envelopes, from very snappy exponential curves for percussion to logarithmic thumps for bass lines.

If VCA's input is unpatched, the module outputs a regular voltage envelope. When an audio signal is patched into the VCA input, the output signal becomes the audio signal amplified by the envelope.

Sending other envelopes or an LFO to VCA input lets you modulate those modulators, quickly creating complex control voltages that go beyond the usual attack-decay envelope.

Combine this with the SUM output, which sums the two channels, and the attenuverters, which can quickly attenuate or invert the signal, and you have a whole array of signal processing capabilities.

The TRIGGER input fires a Attack-Decay envelope, while the SLEW input will affect the rate of change of the signal.

The trigger for channel 1 and 2 can be linked together, so you can fire two envelopes with one patch cable.

Each channel has an End of Cycle output, (EOC) this outputs a short trigger at the end of each envelope cycle.

The output voltage ranges from -10 to +10 volts, set with handy output attenuverters.

The CYCLE switch starts looping the envelope, creating LFO's that go up to audio rate, and that can also be used as an interesting sound source.

There are many ways to utilise Delta-V.

Notes: Popple is an 8hp multimode stereo filter based on the Mutable Instruments Ripples V1 filter section. Popple maintains the buttery smoothness of Ripples filter while giving you two separate audio paths. The audio paths share a resonance, control, a frequency cutoff control, resonance CV input, and a v/oct cutoff CV input. Each channel then has it’s own cutoff CV input with attenuverters (which are normalled to a 2.5V signal).

Popple will also self-oscillate at high resonance settings, when coupled with the v/oct CV control, it can also act as a dual sine wave oscillator.

While this module has little to do with the original Turing Machine (by Alan Turing), it is a shift register based sequencer. You cannot program this sequencer, instead it builds random sequences that can be locked in.

Alan comes tested, calibrated and ready to bring random voltages.

The After Later Audio panel is black and gold and made from FR4. The package will include a power/ribbon cable and a one year warranty.

Notes: nRings

This is a new build of a micro version of Rings from Mutable Instruments. MicroRings, also called NanoRings, retains all the same functionality as a full-size Rings module.

The module is fully assembled, tested, and calibrated. Eurorack power cable is included.

These modules use tall bushing potentiometers to offer a more stable feel.

Notes: Pique (uPeaks) 1U Intellijel Format

This is a 1U (Intellijel format) version of the Pique module which is based on the popular Peaks module from Mutable Instruments. It can be an ADSR-style envelope generator, an LFO and a drum emulator.

The module is calibrated, comes with a power cable, and a one year warranty.

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. The headphone output and line outputs have separate level controls, making it easy to monitor while performing or recording.

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.

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: Erica Synths Fusion Ring Modulator - a classic design ring modulator with germanium diode ring + vacuum tube to boost and shape audio and carrier signals.

Germanium diodes enrich the sound by adding extra harmonic content meanwhile vacuum tube adds evilish overdrive to audio and carrier signals. As a result you get one of the most versatile ringmodulators around!

All Fusion modules by default are configured to work with regular eurorack PSU.

Configurable power supply - standard eurorack +-12V conection OR eurorack +-12V plus Erica Synths Tube heater PSU

Due to the fact that cold tube heaters have lower resistance, Fusion modules have significant power consumption peak at startup, when power consumption almost doubles for 1-2 seconds. This is not a problem with linear PSUs that have power inertia, but may cause switching PSU internal protection turn off the power supply. Please make sure your PSU has some headroom before installing multiple Fusion modules.

Notes: Erica Synths Black Dual VCF is a dual multimode filter with CV control over cutoff and resonance for serious modular patches.

At the core of this VCF is a highly stable, custom multimode VCF chip AS3320 (produced in Riga, btw). This module can be used as two independent VCFs with simultaneous HP, BP and LP outputs, controls can be linked to stereo application and both VCFs can be chained in series or parallel to the summing output for ultimate modulations. Bonus feature - the 16 band spectrum analyser gives you visual feedback on what happens on summing output.

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
-LS.CV: CV input for Loop Scale. Allows for CV control of this parameter.
-A.CV: CV input for Attack. Allows for CV control of this parameter.
-D.CV: CV input for Decay. Allows for CV control of this parameter.
-S.CV: CV input for Sustain. Allows for CV control of this parameter.
-R.CV: CV input for Release. Allows for CV control of this parameter.
-GATE: Gate input for ADSR mode as well as Gate/Loop mode
-OUT: Output of final envelope for all modes.

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.

Connections:

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: 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: VCO:

- Tune: manual tune control (with an internal jumper the range can be set to ~ +/-1 half an octave or ~ +/-2.5 octaves)
- Oct: range switch -1 / 0 / +1 octave
- Mod: modulation depth (attenuator wired to the Mod. socket)
- Dest: switch that is used to address the modulation to frequency modulation (position FM) or pulsewidth modulation (positon PM), in centre positon no modulation
- PW: manual pulsewidth control for rectangle waveform, PW can be also modulated by the Mod. input as mentioned above
- Wave: waveform switch (sawtooth / off / triangle), the sum of the waveform chosen by this switch and the rectangle is fed into the VCF (to turn the rectangle off the PW control has to be set fully CCW or fully CW)
- 1V/Oct. (socket): external CV input for VCO frequency (1V/octave)
- Access to internal bus CV (via jumper, optional, please remove the bus jumper if this feature is not used to avoid unwanted frequency modulation as then the unused CV line of the bus works as a kind of antenna)
- Triangle core VCO, frequency range about 32Hz ... 8kHz

Balance unit:

- The balance unit is made of two VCAs which are controlled by the sum of manual Balance control and the balance CV input in the opposite direction.
- The audio input of VCA1 is hard-wired to the VCO output, audio input 2 is connected to the socket Ext.In.
- The output of the balance unit is used as audio input for the VCF
- Bal.: manual balance control, fully CCW the internal VCO is used, fully CW the external signal (Ext.In) is used, at centre position both signals have about the same level
- CV Bal.: CV input for balance (range about 0...+5V)
- Ext. In: external audio input for VCA2, about 5 Vpp level required for similar loudness as the internal VCO
- This socket is normalled to the internal VCO suboctave f/2 signal (rectangle with half the frequency), if no external signal is applied the suboctave signal is used as the second signal for the balance unit

VCF:

- 24 dB low pass
- Frq: manual frequency control
- FM1: frequency modulation depth (attenuator wired to the VCF FM1 socket, the socket is normalled to the internal Envelope signal and then FM1 controls the modulation depth of the internal envelope applied to the filter)
- FM2 (socket) : second CV input for VCF without attenuator (about 1V/octave), can be used e.g. for VCF tracking by connecting the same CV which is used also for the VCO frequency
- Res: manual resonance control (up to self oscillation)
- If the VCO is turned off (waveform switch = centre position, pulsewidth control = fully CCW or CW) and the VCF resonance is set to maximum the module can be used as a sine oscillator, the tracking at socket VCF FM2 is about 1V/octave (not as precise as the VCO but much better than most other filters)
- ~ 11 octaves frequency range (~ 10 Hz ... 20kHz)

VCA:

- Gain: manual amplitude control (initial gain), can be used to open the VCA without envelope signal
- VCA (switch): used to switch between gate and envelope as control signal for the VCA, in centre position the VCA is not controlled by envelope or gate
- Note: when gate is used the VCA is controlled directly by the gate signal (i.e. hard on/off), this may lead to clicking noise under certain conditions (especially with low VCO/VCF frequencies)
- 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: 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: 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.
