Tags: Envelope generator module

Notes: Module A-140-2 contains two ADSR type envelope generators behind a front panel with 8 HP only.

Each ADSR provides these controls and in/outputs:

- LED (displays the envelope output)
- A: manual Attack control
- D: manual Decay control
- S: manual Sustain control
- R: manual Release control
- Gate Input
- Retrigger Input
- CVT Input with attenuator (CVT = CV Time)
- Envelope Output 1
- Envelope Output 2

The output voltage range for each envelope is 0 - 10V. The time range of Attack/Decay/Release is about 1ms to 30s.

By means of internal jumpers one can select which time parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question).

Socket CVT can be normalled to an internal fixed voltage (i.e. the switching contact is connected to an internal fixed voltage). That way it's possible to change all time parameters simultaneously by means of the CVT control.

Another jumper is used to set output 2 to normal or inverted envelope.

And another jumper is used for the normalling of Gate 2 to Gate 1 (i.e. ADSR#2 is also triggered by Gate 1).

Two more jumpers are used for the optional bus access to the gate signal of the bus for each ADSR. Changing the positions of the mentioned jumpers allows to modify the factory settings.

Notes: Super-versatile quad envelope generator and LFO source from the Vancouver Eurorack brand. All CV controllable and with tons of shaping options.

Supplier's notes:
The Intellijel Quadrax consists of four independent, CV-controllable channels, each of which can be configured to perform any one of the following functions:

- An AD (Attack, Decay) envelope
- An AHR (Attack, Hold, Release) envelope
- A cycling envelope (resulting in a unipolar LFO)
- A pulse burst generator (Finite repeated functions that ascend or descend in amplitude)
- A morphing, bipolar beat syncable LFO

The envelopes all feature a continuously variable response curve, ranging from logarithmic through linear to exponential, and each stage can be as snappy as 0.3 ms to as lengthy as 20 seconds.

When set to Burst mode, the channel generates a rising or falling burst of pulses, with full control over the length of the pulse burst, the number and shape of the bursts within it, and whether the bursts increase or decrease in amplitude over the burst.

AD, AHR, Cycling and Burst modes all feature a user-selectable maximum output level of either 5V or 10V.

LFO mode offers control over the frequency and waveshape, while providing a unique morphing feature that creates numerous variations of the selected waveshape. LFOs can be either free-running or beat-synchronized using the channel's TRIG input.

Channels can be chained together to create complex multi-stage envelopes, with each channel triggered by the previous channel's trigger input, end-of-rise, or end-of-fall. This enables multiple function generators to fire simultaneously, or it enables the creation of complex multi-stage envelopes by allowing the linked function to fire either at the end of the previous function's rise time, or at the end of its fall time.

Four freely-assignable, step-attenuverted CV inputs are capable of modulating any or all of the various parameters across all four channels using the built-in CV matrix, and built-in attenuversion for each assignment.

Quadrax remembers its current state (Mode and CV assignments, channel links, etc) and retains that state even if power is removed, meaning Quadrax will always turn on in exactly the same state as you last left it.

Notes: The ‘Pip Slope’ (rev II) is a compact envelope and function generator. It supports both Attack/Decay and Attack/Sustain/Decay type envelopes with both direct and voltage control of Attack and Decay times. Envelope shapes can be morphed between exponential, linear and logarithmic type slopes. Envelopes can be made to loop, repeating infinitely or decreasing with time or amplitude for echo and bouncing ball type effects. An ‘End of Cycle’ trigger output further extends the envelopes functionality for both clocking and burst or fill type effects.

The improved Pip Slope adds a number of new features and updates over the original Pip whilst keeping the same size. Improvements include increased output resolution, finer control of fast envelopes, a new morphing shape control, switchable 5v or 8v maximum envelope level, additional loop modes and an additional trigger output.

Features:
Compact envelope and function generator in 4HP.
Trigger and gate inputs.
Voltage and direct control of attack and release times.
Snappy or super long envelope times – ranging approx 1ms to 7 minutes per stage.
Optional self looping ability with 3 different loop modes: Decreasing amplitude, decreasing time, and regular loop.
Shape control that morphs the envelope shape from logarithmic to linear to exponential curves.
End of Slope trigger output that fires a trigger at the end the envelope or loop cycle.
Selectable 5v or 8v max envelope level output.
Reverse polarity protection.
Skiff friendly.
Designed and Made in the UK.

Notes: Successor to the excellent Metropolis, the Metropolix is a performance-focussed step sequencer with some really neat features, including modulation and sub-sequences in Loopy mode.

Supplier's Notes:
The Intellijel Metropolix is a unique and powerful Eurorack format musical sequencer. With an abundance of hands-on, tactile controls and a wealth of modulation possibilities (both internal and external) you can quickly and easily create infectiously musical sequences that are never boring. Even the simplest riff can be brought to life with seemingly endless options to create variations or real-time manipulations. Equally at home in the studio or a live improvised performance, the Metropolix is sure to become a staple source of fresh ideas and killer riffs in your creative process.

Width: 34HP
Depth: 25mm
Power: 95mA @ +12V 10mA @ -12V

On first blush, it appears to be a simple 8-stage sequencer - but there is far more functionality than first meets the eye:

There are two tracks (TRK 1 and TRK 2) that are variants of the single master pitch/gate sequencer, which is programmed via the PITCH sliders, PULSE COUNT and GATE TYPE switches. Each track interprets the master sequence in a variety of ways - creating complementary sequence variations that enable you to generate counterpoint, polyrhythms, and all manner of sonic movement (both subtle and extreme). Each of these tracks has its own playback ORDER, sequence LENgth, clock DIVision, SWING amount, SLIDE time, and track GATE lengths. Other track-based sequence variables are accessible from the TRACK MENU, and include Pitch Slider inversion; sequence note range; track transposition; and more. In addition, Tracks 1 & 2 both have multiple lanes of per-stage playback parameters, including: GATE override; PITCH override; RATCHet count; PROBability of playback; ACCUMulating transposition, and a dedicated CV lane. Each stage also has a SKIP feature, and a pitch SLIDE option.

8 separate and individual MODulation lanes are accessed via the MOD button. Each MOD lane has 8-stages of modulation values and its own playback ORDER, LENgth, and clock DIVision; and each lane is routable to one of Metropolix' two assignable outputs or to dozens of internal destinations, allowing for some sophisticated and powerful self-modulation.

A trio of AUX inputs allows for external modulation of user-assignable sequencer parameters for even greater variation, while two assignable CTRL knobs give you direct access to the parameters you want to adjust most frequently during a performance. With dedicated Pitch/Gate outputs for both Track 1 and Track 2; two totally user-assignable outputs (A and B); and internal MOD routing, Metropolix features a wealth of patching opportunities.

Metropolix also features a Loopy mode, allowing you to instantly play back short sub-sequences, or even "play" the stage buttons directly (like a 'keyboard').

Metropolix stores up to 64 preset configurations (in 8 banks of 8 presets), and all live settings are stored in EPROM, ensuring that your Metropolix will always power up exactly as you left it - even if you haven't saved them to a preset. By default presets can change all the structural (menu-based) elements of your sequencer without overwriting the front panel controls, but full recall is also available.

The operation of the Metropolix is optimized for live performance and jamming, with quick access to all the most important performance parameters, and the ability to greatly affect your sequences with a single slider or switch.

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

Notes: The module contains two ADSR type voltage controlled envelope generators with exponential curve shapes (charge/discharge curves of a capacitor) behind a front panel with 8 HP only.

Each ADSR provides these controls and in/outputs:

- LED (displays the envelope output)
- A: manual Attack control
- D: manual Decay control
- S: manual Sustain control
- R: manual Release control
- Gate Input
- Retrigger Input
- CVT Input with attenuator (CVT = CV Time)
- Envelope Output 1
- Envelope Output 2

The output voltage range for each envelope is 0 - 10V (10V = attack peak).

The time range of Attack/Decay/Release is about 1ms to 30s.

By means of internal jumpers one can select which time parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question).

Socket CVT can be normalled to an internal fixed voltage (i.e. the switching contact is connected to an internal fixed voltage). That way it's possible to change all time parameters simultaneously by means of the CVT control.

Another jumper is used to set output 2 to normal or inverted envelope.

And another jumper is used for the normalling of Gate 2 to Gate 1 (i.e. ADSR#2 is also triggered by Gate 1).

Two more jumpers are used for the optional bus access to the gate signal of the bus for each ADSR.

Notes: Javelin is a module that is basically an ADSR envelope with integrated VCA. However, it has several features that make the module an expressive sound shaping tool.

Three level ranges determine the total amplitude of the envelope, additionally three different time ranges are integrated, which can be switched between.

The accent behaviour is also unique. If several gates are applied to the Accent input at the same time, the envelope rises slightly with each gate.

Features:

Attack-decay-sustain-release envelope
Integrated VCA
Unique accent behaviour for expressive sequences
Reset input
CV control over attack and release
Looping mode for LFO-like modulations
Mode switch for gate and trigger behaviour
Linear, moderate or steep exponential shape
Short hold in the peak of the attack for more punch
Power consumption: 93mA at +12V and 65mA at -12V

Notes: Two independent Contour Envelope Generators in a single 12hp wide Eurorack module. These are very accurate replicas of the Model D contour generators, with identical circuitry and component values running on the correct +9.3V and -10v supply voltages of the original; so they exactly replicate the original envelope response along with all of it eccentricities. Extra features include manual trigger buttons and envelope status LED's.

The contour generators played a larger part in the sound of the Model D than many people realise. There are two factors that make them unique, firstly the exponential slope when is used in conjunction with the (near) linear slope of the original VCA which is responsible for the famous Model D "punch". Secondly, the re-trigger behaviour is quite unique, multiple retriggering increases the output level so that either the volume increases incrementally, or the filter opens incrementally with each extra key press.

AJH Synth have added independent Decay switches for each individual Contour Generator rather than the shared switch on the original synthesiser, these switches change the Contour response from AD (switch up) to ADSD mode (switch down).

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

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

Notes: A clever hybrid of quad VCA, function generator and more in this chunky module. Four channels of oscillators, envelope generators and VCAs, plus slew, voltage sources and plenty of CV control.

Supplier's Notes:
Four channels of function generator, oscillator, slew limiter, envelope, and VCAs. This module brings the ultimate in flexibility as it can be used as a standalone synth voice, a massive amount of modulation, or a four channel envelope generator w/ mixer. We believe this makes QARV a great first module and a great addition to the largest of systems.

All four channels have the following features:

Uni-polar oscillator mode
Attack and release time control via potentiometer and via input jack
Shape control that controls shape for both attack and release
Output attenuverter
VCAs that normal to each subsequent channel (CH1 -> CH2, etc.). So you can get a mix of all four channels out of the CH4 VCA output (unless you patch a VCA output from an earlier channel)
Channels 1 & 4

Voltage source (CH1 - 5V & CH4 - 10V)
CH1 & CH4 can be switched between IN (slew mode) and TRIG (envelope) mode
RISE and FALL gates. You can use our G&T module to turn these gates into triggers.
Channels 2 & 3:

Bi-polar oscillator mode
Dedicated IN and TRIG jacks (helpful for adding offset to a triggered ENV)
BOTH input jack to simplify patching both the attack and release (also inverts the input to give more standard pitch tracking of higher voltage equals higher pitch)

Notes: A 6HP version of Mutable Instruments Peaks that adds CV inputs and attenuverters for each of the four parameters.

It can be an ADSR-style envelope generator, an LFO and a drum emulator. By default, the Dead Man's Catch (DMC) firmware will be loaded, which adds the Alt ENV, ALT LFO, ALT Tap, Alt Drum modes below.

Notes: Module A-171-2 is a voltage controlled slew limiter with a lot of additional features beyond a simple slew limiter. It's mostly a licensed copy of Ken Stones VCS which is in turn based on the Serge VCS.

Typical applications:

- VC Slew Limiter / VC Portamento / VC Low Pass Gate:

Cycle switch = off, no trigger signal applied to Trig socket: Voltage controlled Slew limiter or portamento generator: the signal applied to the signal input is "slewed". The slew up and down times are controlled manually by means of the Up and Down controls, the effect of the CV Up and CV Down control voltages are controlled by the CV Up and CV Down controls, in exponential mode these controls also affect the slew shape (see symbols at the CCW and CW positions of the controls).

If an audio signal is applied an short slew rates are chosen the module works as a simple VCF/VCA combo.

- A/D Envelope Generator / Pulse Delay / Subharmonic Generator:

Cycle switch = off, trigger signal applied to Trig socket, no input signal: Simple Attack/Decay envelope Generator, the rise and fall times are controlled like the slew up/down times above, including the shape of the falling/rising slope of the envelope, the exp. CV input can be used to change both attack and decay simultaneously.

At the End output a pulse appears as the end of the envelope is reached (less than about 20mV), this can be used as a pulse delay.

If a series of triggers are applied to the VCS faster than the total rise and fall times, the module will divide the incoming signal by a whole number. In the audio range the output will be the sub-harmonic series.

- VCLFO / VCO:

Cycle switch = on, no trigger signal applied to Trig socket, no input signal: Voltage controlled LFO/VCO, the rise and fall times of the waveform are controlled like the slew up/down times above, including the shape of the falling/rising slope
the exp. CV input can be used like the CV input of a VCO or VCLFO, the response is exponential but not exactly 1V/oct.

Notes: *** Free software update available as a free download, along with updated documentation, at the Mob of Emus product page on the Rossum Electro-Music website***

A lot to unpack here. Six-channel multipurpose oscillator/noise source/modulation generator with quantisation, trigger generators and even more. Seriously powerful all-round digital goodness.

Supplier's Notes:
Mob of Emus is a powerful music and sound design tool that packs an enormous amount of creative power into an amazingly compact 16HP module.

Mob of Emus gives you six channels of oscillators, noise sources, cyclical and 1-shot modulators (including LFOs, envelopes, and various other shapes), sample and hold waveshapes, slow random modulators, triggers, rhythm patterns, and quantization (of both internal and external signals) in pretty much any combination (well, any combination of six channels, anyway).

In addition to being able to independently program the function of each individual channel, Mob of Emus' Hex Mode provides a macro control layer that allows you to control all of its channels simultaneously (while maintaining the relationships of each channel's independent programming).

What's more, Mob of Emus' "harmonic" control structure makes it extremely easy to combine its oscillators into rich additive timbres, to combine its LFOs into stacked harmonic low frequency modulation waves, and to create modulation sources and triggers with intricate polyrhythmic patterns.

With an external trigger input, six CV inputs that can operate in six different control modes, six independent outputs, and an assignable mix output, Mob of Emus can operate as the heart of an almost unlimited variety of patches. And its 8 real-time controls will give you immediate hands-on access to a channel's (or all six channels') key parameters, inviting (and rewarding) exploration and improvisation.

Mob of Emus features include:

Six channels that can function independently or can be further controlled by a Hex Mode macro layer that lets you control all six simultaneously. Channels can be:
Wide-range digital oscillators
Noise sources
Cyclical and 1-shot modulators (including LFOs, envelopes, and various other shapes)
Sample and hold waveshapes
Slow random modulators
Triggers
Rhythm patterns
Quantizers (of both internal and external(!) signals)
Six CV inputs that can function in six different control modes
Eight real-time controls for immediate access to key channel parameters
Six individual channel outputs and an assignable mix output
The ability to store and recall 12 user presets
And much more.

Mob of Emus is 16HP wide and 25mm deep.

Power requirements (max): 130mA +12V, 25mA -12V. Reverse polarity protected.

As of March 2021, there has been a been a small bug fix to the recent software update for Mob of Emus.

The update fixes a bug where holding the Channel Selector Buttons for a short time to select a single channel and deselect any others was not working correctly.

The update fixes a bug where some Hex Mode parameters were not ignored when Hex Mode was set to off.

The update introduces a feature allowing users to double-click and hold the Hex button to reset all Hex Mode parameters and set Hex Mode to on.

Notes: Nice dual-module gate/envelope generator which can run off any audio signal. Feed it drums, synths, samples or a mic input and and generate CV modulation signals.

Supplier's Notes:
The Percussion Interface (PI) and PI Expander are a pair of Eurorack modules that generate gates and envelopes from acoustic drums, samplers, drum machines, and virtually any audio source.

Converting microphone, instrument, line and modular signals into CV and clock/gate signals, the PI and PI Expander are suited for synchronizing sequencers or other modules to the rhythm of an audio track or live percussion. The modules can simultaneously be used as a pre-amp for microphones or line-level signals, while generating inverted envelopes useful for side-chaining. The PI module contains all the core functionality and can be used without the Expander to conserve space. The Expander requires the main PI modules and adds three gain stage options, a modular-level audio output jack, a 1/4" (6.35mm) input jack, and envelope attenuation capabilities. The two modules are only sold together, they are not available separately.

Notes: Explore modulation beyond the standard ADSR with Verbos's complex polyphonic envelope, opening up the potential of ADAsR and AHDsR slopes. Use the four envelopes independently or trigger sequentially in three separate modes.

Supplier's Notes:
The Verbos Polyphonic Envelope module is a set of four envelope generators which can be used together or independently. Cascade logic allows the four envelopes to trigger sequentially with subsequent envelopes starting at the Hold, Decay or End of the previous envelope.

Each envelope offers its own gate input, CV output and end pulse output, so it can be used in up to four-voice polyphonic patches. The three skew controls allow the times to change as each new envelope is switched on. All parameters can be voltage controlled.

Power consumption: 75mA at +12 V and 30mA at -12 V

HP : 22

Notes: Module A-147-2 is the successor of the VCLFO A-147 but offers much more features than the predecessor. The module is made of these sub-units:

- VCLFO: voltage controlled low frequency oscillator
- VCA: voltage controlled amplifier, switchable to voltage controlled polarizer
- VC delay unit: voltage controlled linear attack envelope (only one parameter: attack) for delayed LFO operation in combination with the VCA (e.g. delayed vibrato/tremolo)

LFO: The voltage controlled LFO has the waveforms Triangle, Sine, Sawtooth and Rectangle available and features a Reset/Sync input. Triangle/Sine and Rectangle are displayed by means of dual-colour LEDs (probably red/green), Sawtooth has a unicolor LED available (probably blue). The output levels are about -4V...+4V for Triangle, Sine and Rectangle. The Sawtooth level is about 0...+8V.

The CV control can be switched to attenuator or polarizer ("CV Mode" switch). In polarizer mode the CV inputs affects the frequency in the reverse manner when the CV control is left from the centre position. In the centre position CV has no effect and right from the centre the control works like a normal attenuator. The frequency range (without external CV) is from about 0,005 Hz (i.e. about 3 minutes per period) to 200 Hz (with external CV max. frequency about 1kHz). In addition a ultra-low mode can be activated by means of an internal jumper. When the ultra-low jumper is set a fixed voltage is connected to the switching contact of the "LFO CV" socket. In polarizer mode of the CV control that way extremely low frequencies (up to one hour period and more) are possible. For this a jumper has to be installed on the pin header JP6. In the factory a dummy jumper is installed on the pin header JP7 "Dummy". JP7 has no function and is used only for "parking" of the jumper. Simply remove the jumper from JP7 and plug it on JP6. JP6 is located behind the CV control.

VCA: This is a linear VCA that can be switched to "normal" VCA (i.e. kind of a voltage controlled attenuator) or voltage controlled polarizer ("VCA Mode" switch). In the "normal" VCA mode amplification +1 is achieved with about +5V control voltage. In polarizer mode the amplification ranges from about -0.5 (i.e. inverted signal with about 50% level) with 0V CV to +0.5 (i.e. non-inverted signal with about 50% level) with +5V CV. With about +2.5V CV the signal is suppressed. Details about the functioning of a voltage controlled polarizer can be found in the description of the module A-133. In this mode the VCA can be treated also a DC coupled ring modulator (similar to A-114).

The VCA of the A-147-2 has three sockets available: "In" (signal input), "Out" (signal output) and "CV" (control voltage input).

The Triangle Output of the LFO is normalled to the VCA signal input by means of the switching contact of the "VCA In" socket. If another LFO waveform (or any other signal) should be processed by the VCA the corresponding signal has to be patched to the "VCA In" socket. The VCA can be used also independently from the LFO and the Delay CV. In this case the VCA sockets In, Out and CV have to be patched accordingly. The VCA can be used also as waveshaper for the LFO signals (e.g. by patching VCA In and VCA CV to different LFO signals, if necessary via attenuator A-183-1 or offset generator/attenuator A-183-2).

Attack/Delay: The third sub-unit of the module is a simple, voltage controlled envelope generator that has only the parameter "Delay" (or Attack) available. This unit generates a linear increasing voltage that starts from 0V after each Delay Reset until it reaches about +5V. Then the voltage remains at +5V until the next Delay Reset occurs. The inclination or gradient is controlled by the manual Delay control and the Delay control voltage ("Delay CV" input). The waveform is linear, the control scale is exponential. The output voltage is displayed by a green LED and available at the "Delay Out" socket.

The manual Delay control ranges - without external "Delay CV" - from about 5ms (fully CW) up to 2 minutes (fully CCW). By means of an external voltage applied to the "Delay CV" socket this range can be extended. A rising CV shortens the delay time (behaviour like a VCO)!

The Delay output voltage ranges from about 0V to +5V. The rising edge of the gate, clock or trigger signal applied to the "Delay Reset" sockets resets the Delay output voltage to 0 V.

"Delay Out" is normalled to the VCA CV input by means of the switching contact of the "VCA CV" socket and consequently controls the Triangle level provided that no other patch is made. A typical example is the usage of a Gate signal (e.g. from a USB/Midi-to-CV/Gate interface) as Delay Reset. That way a delayed vibrato or tremolo can be realized if the VCA output is patched to the frequency CV input of a VCO (or VCF), or the CV input of a VCA.

Notes: The MiniMod Multi Burst Envelopes module generates variable length bursts of repeating envelopes that can change over time, with CV control of all functions.

The BURSTS control selects a "Burst Sequence" of between 1 and 40 individual envelopes. The envelope shape of a burst is chosen with the rotary switch, or it can be varied using an external CV, so that it is even possible to chose a different envelope shape for each individual burst in a sequence.

The width of the envelope (i.e. the attack and decay time) is varied with the P-WIDTH control and this can also be CV controlled as a sequence is progressing, so it is possible to vary the envelope speed of each individual envelope burst while a Burst Sequence is running.

The repeat time of individual bursts in a Burst Sequence is set with the LFO Rate control. The LFO rate can be varied with an external CV as a sequence is progressing, so the gap between envelopes can speed up or slow down over time. An external clock can also time the bursts in a burst sequence instead of, or in addition to the internal LFO. Bursts can also be manually incremented with the CLK push button.

The SLOPE control allows Bursts to start quietly and build in level to maximum, or they can start at full level and then reduce in level as the Burst Sequence progresses. In the centre position all Bursts are of equal level.

Unlike conventional analogue envelope modules, the waveform of each envelope can be controlled with a slider or CV without changing the envelope timing. With a wide time range from an hour to 2.5kHz, and a plethora of CV inputs and attenuverters, it can be used as an LFO, audio-rate oscillator, slew limiter, waveshaper, ASR/ADSR/complex EG, independent audio/CV VCA, envelope follower, sidechain processor, and general utility module. Each channel has dedicated linear outputs plus attenuverters and offset controls for the variable waveshape outputs, making it an ideal modulation source and stereo VCA.

Notes: A fully modular, Eurorack-format version of the excellent Dark Energy synth, the A-111-5 offers VCO, VCF, LFOs, VCA and envelope generator in a compact format. Brilliant value for a starter system.

Supplier's Notes:
Module A-111-5 is a complete monophonic synthesizer module that includes these components (modular version of Dark Energy):

VCO
Manual tune control (with an internal jumper the range can be set to ~ +/-1 half an octave or ~ +/-2.5 octaves)
Range switch -1 / 0 / +1 octave
Frequency range about 10Hz ... 12kHz - FM (frequency modulation) control with modulation source switch (LFO1 / off / ADSR)
Manual pulsewidth control for rectangle waveform
PWM control with modulation source switch (LFO2 / off / ADSR)
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)
External CV input for VCO frequency (1V/octave)
External CV input for external PWM of the rectangle - internal CV input for frequency (1V/octave) connected to the A-100 bus via jumper, the jumper can be used to interrupt this internal connection if not wanted

VCF
24 dB low pass
~ 12 octaves frequency range
Manual frequency control
Tracking switch half - off - full (internally connected to the external frequency CV input of the VCO, i.e. the VCF tracks to the VCO if the switch is set to "half" or "full" position)
XM: exponential FM (frequency modulation) control with modulation source switch (LFO2 / off / ADSR)
LM: linear FM (frequency modulation) control to modulate the VCF by the triangle of the VCO in a linear (!) manner
Manual resonance control (up to self oscillation)
External audio input (this signal is added to the VCO signal)
External CV input for filter frequency - 1V/octave tracking for usage of the VCF as a sine wave oscillator (not as precise as the VCO but much better than most of the other filters)
VCA
Manual amplitude control
AM (amplitude modulation) control with modulation source switch (LFO1 / off / ADSR)
External CV input for VCA amplitude - 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 VCA)
LFO1 and LFO2
Manual frequency control
Waveform switch (triangle / off / rectangle)
Range switch (low, audio, medium) - LED display (dual green/red color for positive/negative share of the signal)
The inverted LFO1 signal is available as an additional socket (to use the LFO1 signal for external modules)
An internal jumper can be used to select between the LFO1 signal or the inverted LFO1 signal

ADSR
Manual controls for Attack, Decay, Sustain, Release
Range switch (long, short, medium) - blue LED display
ADSR signal is available as an additional socket (to use the ADSR signal for external modules)
Gate input connected to the A-100 bus via jumper, the jumper can be used to interrupt this internal connection if not wanted

Remarks:
As the LFO frequencies can go up to moderate audio range (~ 5kHz) even audio FM effects of VCO (pitch and pulsewidth), VCF and ADSR are possible.

If the VCO is turned off (waveform switch = center position, pulsewidth control = fully CCW) and the VCF resonance is set to maximum the module can be used as a sine oscillator. The sine can be modulated in a linear manner from the triangle wave of the VCO and by LFO2 in an exponential manner at the same time !

From the factory the socket labelled "LFO1" outputs the inverted LFO1 signal. But as the module has several internal pin headers available even another signal may appear at this socket by changing the internal module patch. These six pin headers are available: LFO1 output, LFO2 output, ADSR output, inverter input, inverter output, output socket. The internal default patch is LFO1 -> inverter input, inverter output -> output socket (i.e. socket = inverted LFO1). But even another signal can be patched to this socket (e.g. inverted ADSR, non-inverted LFO1, inverted or non-inverted LFO2). It is also possible to add a blind panel next to the A-111-5 with a couple of sockets that are connected to the corresponding pins of the A-111-5 pc board. The in- and outputs of the VCO, VCF and VCA are not available as pin headers because the VCO, VCF and VCA are internally connected in the circuit which is used in this module.

Notes: Dual tidal modulator with max, min & mix outs

FranKinksTides is a 18hp dual Tides (based on the Swirls pcb layout) with the max/min circuit from Kinks and some switches for sync, quadrature, pll and fm operation . It can be a double/complex oscillator, a dual function generator or any combination of oscillator, Lfo and Envelope generator with lots of cv control plus some interesting cross-modulation and sync features.

Some improvements in version 1.2:

-Mix output is now buffered, no signal bleeding on single outs.
-Mix pot controls also the balance of the signals sent to the max/min circuit.
-Uni/bi switch now also determines the signal sent to FM1.
-Clock/sync switch has now a center OFF position, no need of plugging a dummy cable in the Clock1 when using Sheeps firmware to avoid ultra fast sound bank changes.
small improvements for DIY:
-Bigger font size on the pcb.
-Parts renumbered for easy DIY.

Notes: Tangrams

Push (or Pulse) the Envelope

Snappy, classically analogue envelopes with visually intuitive controls. Add a powerful, cv controllable cyclical gate generator, integrated VCA, and trigger buttons -then double it-now you've got Tangrams.

Tangrams, like the Dual ADSR before it, is a dual analogue core-envelope inspired by the Roland SH-101 / System 100m design with several enhancements. Taking further inspiration from trapezoidal function generators like the one on the EMS Synthi, Intellijel have added a voltage-controlled pulser circuit to link the triggering of two envelopes - allowing for delayed one-shots, cycling organic envelopes, and more. In addition, Intellijel added two VCAs for level control of each envelope, or alternatively, direct injection of the signal you'd like to envelope - freeing up your other VCAs.

The Pulser

The Pulser can be thought of as a way to set both a gate ON time (T1) and an OFF time (T2). In this way, you could configure a cycling ADSR that has a gate time that is different from the interval between gates. Alternatively, you can create a sequence where ADSR2 is triggered by a delayed amount of time after ADSR1 is triggered (either cyclically or in a single shot sequence). The panel switches for routing or disabling the pulse sources allow for even more complex combinations of control beyond these examples. This special combination of functions can yield a plethora of interesting and organic envelope and gate patterns to be created; cyclical and single shot.

Notes: Gross, gritty, and dark industrial-strength voice on a swappable oscillator platform. Pangolin approved.

Manis Iteritas Alia is a voice based on the architecture of Basimilus. It was designed to be grittier and more aggressive by using only sawtooth waves that are manipulated, modulated, and distorted through a rethought interface. Manis Iteritas Alia is fantastic for leads, basslines, drums, darkness, detuned swarminess, or pure mayhem. Plus, MIA's dedicated envelope output is a great modulation source for the rest of your patch.

MIA is available on Noise Engineering's 10HP Alia oscillator platform. Buy an Alia module and use the included USB cable to connect to the Noise Engineering Customer Portal to check out any other Alia firmware, free of charge, any time.

Notes: 8HP Tides version 2

Notes: Moonwalker is a versatile signal generator that performs as an envelope, lfo, and audio oscillator, with attack and decay time controls

Phase offset is continuously variable from 0 to 360° and inverts the waveform without changing it’s amplitude, and with or without changing it's polarity.

Unipolar mode preserves the output range by offsetting the starting voltage, so it always stays between 0 and +10v

Bipolar mode preserves the starting voltage by offsetting the output range, so it always starts at 0v. The output range will shift from +unipolar, through +bipolar, to -unipolar, through -bipolar back to +unipolar.

The reference waveform does not change phase, but the timing of the rate change between Attack and Decay shift with the phase offset, to ensure synchronous movement.

The phase offset output is half-normalled to the phase offset cv input and skews the waveform from triangle to saw or ramp without changing frequency (when attack = decay).

Notes: Introducing a limited edition re-release of this iconic electronic instrument in a modular format.

This limited edition of 75 units is a tribute to the pioneering work of Dutch musician and instrument maker Michel Waiswisz (1949 - 2008), who first invented the Cracklebox with Geert Hamelberg in the late 1960s.

The Cracklebox was a small, handheld device designed as a way to explore new sonic territories. It was one of the first electronic musical instruments to use circuit bending techniques in the creation of electronic music. It allowed musicians to manipulate and control electronic circuits in real-time, creating a wide range of unique and experimental sounds. He used a circuit from a toy piano as the basis for the instrument, and then added a series of touch-sensitive pads that were connected to the circuit. When a player touched one of the pads, the circuit would be completed, producing a crackling sound.

The Cracklebox was probably the first commercially available portable self-powered alternative 'keyboard' analogue electronic instrument with inbuilt loudspeaker.

In the 1970s about 4000 Crackleboxes were built and sold by STEIM in Amsterdam.

Nowadays many people refer to the The Cracklebox as the archetype of 'glitch' or 'circuit bending'.

In the decades since its invention, the Cracklebox has continued to be an important and influential instrument in the world of electronic music. It is still in use today, and is considered a classic example of the potential of electronic music to create unique and innovative sounds.

This Eurorack recreation includes a 9v battery, swappable through the front panel, this allows to isolate the current flowing through the user's fingers from the Eurorack frame PSU, protecting the user from undesired electrical shocks. The internal speaker has been removed, a transformer has been used instead to isolate the output signal.

The output generated can be used as an audio, as a gate or a cv signal, when using it as a cv source, due to the specific qualities of the signal, users may want to send it through other modules as slews, sample and holds, quantizers to tame/control it's peculiar cv output.

Controls:

- The module features an on/off switch to turn off the 9v battery (remember to turn it off when you turn off your Eurorack system).
- A Power Starve knob, reduces the 9v voltage feeding the circuitry changing it's overall timbre/pitch
- An Output Gain knob to control the output volume.
- A Boost switch to add more presence to the signal.

Notes: The Looping VC-ADSR is a 4-stage, loop-able, envelope generator based on the ENVGEN 8C IC from Electric Druid. The individual sections of the Envelope (Attack, Decay, Sustain, Release, Level and Time) can all be individually controlled via CV.

The module has 5 MODES of operation that can be selected via the pushbutton LED switch with the status indicated by the five LEDs above:

Normal Envelope - Gate signal at the GATE/TRIG input, fires the ADSR.
Trigger Mode - Trigger signal at the GATE/TRIG input fires the AD portion of the envelope. The sustain control determines the final value the envelope rests at after the decay portion has ended.
Gated Looping Envelope - ADSR loops whilst gate signal is high.
Looping Envelope - ADSR loops regardless of gate signal.
LIN response (Hold switch to select between LIN/EXP Mode) - Sets the envelope response to be Linear. The response is Exponential when the status LED is off.
When the envelope is looping, all 5 controls affect the output. Attack and Decay operate, as one would expect. The Sustain control sets the minimum voltage the decay part of the envelope will decay to. The Release sets a release time from the end of the Sustain period to the beginning of the next cycle. When the Sustain is set to 0 you can use the Release control to add a delay between the Attack and Decay cycles.

In Normal Envelope mode the Sustain CV input can be used with an LFO source to add amplitude modulation that gradually increases as the Envelope transitions from the Attack/Decay part of the envelope into the Sustain part. The Level CV is also a useful point for amplitude modulation or can be used for Velocity Sensitivity via CV.

The Time CV is set so that increasing voltage shortens the overall envelope time to better mimic the sounds of percussive instruments.

Notes: The Erica Synths Envelope Generator 2 is a re-triggerable, looping envelope generator with some unconventional features that are very useful for experimental setups. What sets the Black EG2 apart from other envelope generators is its optional GATE LENGTH setting, which allows for generating full ADSR envelopes even if a short trigger is used at the input. Likewise, in LOOP mode, the module outputs a full ADSR envelope instead of a classical AD envelope. The gate length is both manual and CV controlled, which allows for using this envelope generator in compact modular setups controlled by trigger sequencers only.

LOOP/SINGLE

Select between SINGLE SHOT or LOOP modes. When the internal gate is o , the rise and fall times are set via the A and R knobs. When the internal gate is on, all knobs have an e ect on the envelope shape.

The LED gives visual feedback on the envelope state.
GATE ON
Engage the internal gate and you have a full ADSR envelope in loop mode and with a trigger applied to the trigger input in single mode.

G. LENGTH

Set the internal gate length manually

LENGTH CV

This is the internal gate length CV input.

The CV is added to the gate length potentiometer setting

GATE

This is the GATE input

A / D / S / R

These knobs adjust envelope stage times and sustain level

TRIGGER

This is the TRIGGER input. You can retrigger the envelope and start the attack stage again, even if the gate is still high (see Figure 1).

If you wish to use the envelope generator with an internal gate, patch the incoming trigger signal here. The internal gate is linked to the trigger input, not the gate input.

EG OUT

This is the envelope generator output.

Notes: Great value from this versatile percussion module, built around a noise generator and four linked envelope generators, each with its own VCA. Generate hi-hats, envelopes, shape drums or create modulation sequences.

Supplier's Notes:
Ricochet is a compact, fully analogue module featuring four interconnected decay envelopes, each with its own VCA and an integrated noise generator.

The module's design is inspired by the way skipping stones bounce on the water, creating a versatile tool for crafting percussive sounds.

The exponential envelopes are specifically designed to generate dynamic percussive tones. The unique linking function connects the end of one envelope's decay to the trigger of the next, enabling the subsequent envelope to activate once the previous one ends. This innovative feature allows you to create ratcheted envelope.

A front-panel trimmer lets you adjust the threshold for triggering subsequent envelopes, while a rear header enables connecting two Ricochet modules together, or linking the last envelope to the first. This feature transform the Ricochet to a weird sequencer where the steps length depend of the decay times.

Since Ricochet is fully analogic, trig inputs are velocity-sensitive, responding to a standard gates but also allowing attenuation to modify the envelope's velocity (you can play with the dynamic of your sound by attenuating the trigg input. Ricochet is also perfect to play with drum pads).

Each VCA features a gain control that can be pushed to achieve subtle saturation.

All envelopes and VCAs have separate outputs, but there are also mixed audio and envelope outputs. When an individual output is connected, it is removed from the mix. The decay modulation inputs are normalized between each other.

Last but not least, an analogue noise generator is normalised to the first input, so you can use ricochet on it's own to create hi hat kind of sounds

Main features:

- Fully analogue design so everything is responsive to the amplitude
- Unique linked envelopes feature
- Compact 4 envelopes 4 VCAs module
- Linkable to a second ricochet or looping back the last envelope to the first one

Some applications:

- Envelope generator
- Drum shaper
- Hi-hat
- Clap envelope shaper( with short ratcheted envelopes)
- Envelope sequencer
- Trigg delay
- Burst generator

Technical details:

- Fully Analogue design
- 14hp
- Skiff friendly
