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

Features:

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

Notes: Best value Buchla module ever? An official Buchla module produced by TipTop Audio, the 258t is a dual triangle-core oscillator, with sine/sawtooth wave shapes in the top half and sine/square at the bottom. Bags of character.

Supplier's Notes:
Two independent voltage-controlled oscillators. Each has one processing input, a frequency modulation input and a 1V/oct input.

Waveshapes, as well as frequency, can be voltage controlled. Model 258 oscillators feature low sine wave harmonic content, negligible settling error, and high short and long-term stability, even with rapidly changing ambient temperatures.

Trimmers:

There are three trimmers for each oscillator on the back of the module:

1V/oct is the octave tracking trimmer and is set at the factory using high precision instruments.
SHAPE is the trimmer that set the sine wave, for the lower harmonic content of the sine wave.
VC WAVE SHAPE sets the response of the waveshaper to the incoming control voltage. Both SHAPE and VC WAVE SHAPE trimmers are used to adjust the sine wave purity.

Notes: A compact Voltage Controlled Oscillator designed for generating SINE waves, Variable wave-SHAPEs, SUB-Octaves, Oscillator SYNC and Linear FM in the analog domain.

The Sub-Timbral Oscillator is the more subtle and melodic friend to the DPO's complex harmonic lattice.

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: Viol Ruina is an all-analogue distortion and lowpass filter with an internal envelope follower and self-modulating cutoff. The four-pole design is reminiscent of the classic filters we all know but with a completely new and slightly ridiculous twist. The independently addressable distortion circuit takes VR into overdriven paradise with a shocking amount of drive. Built-in envelope following makes an easy way to create dynamic patches with the flick of a switch, and feedback FM takes VR to a whole new realm of filthiness. Run a sound through VR, you'll get something cool out of it.

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

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

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

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

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

- Additional hi-pass filter in series quickly cuts the boomy low end

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: 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: 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: 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.

Technical specifications:

Audio output amplitude: 10 Vptp
CV input (full sweep): 10 Vptp
Panel width: 18HP
Module depth: 35mm
Power consumption: 40mA@+12V, 36mA@-12V

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

Notes: 32 unique audio effects arranged in 4 banks of 8 effects. Three effect controls plus analog Dry/Wet control with dedicated CV input. High quality stereo signal pass. Assignable CV input to effect controls or to Sample Rate reducer (changes internal clock). Four user storable presets - stores selected program and all three controls. Spin FV-1 based.

The last used effect, assigns and presets are always remembered.

32 effects are simultaneously available, but FX AID can be reflashed with other user selected Happy Nerding effects in any order. Also the possibility to run freely available third party effects will be added too.

Reflashing procedure is quite easy: playing 40 sec long "wav" file of line level amplitude to CV input.

Reflashing mode: hold both buttons for 10 sec.

Please note the reverse CV operation of the Dry/Wet control: positive CV crossfades from Wet to Dry, and negative CV crossfades from Dry to Wet.

By default it runs on 32.77 kHz and, if sample rate reduction assign is used, this sample rate can be decreased down to 150 Hz or brought up to 48 kHz.

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: 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: 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 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.

- 1V/Oct. (socket): external CV input for VCO frequency (1V/octave)

- 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: Row Power is a clean, regulated, and protected power solution for eurorack systems. Row Power 35 provides 35W of power, suited for any typical eurorack row (84HP to 168HP):

+12V @ 1.4A
-12V @ 1.25A
+5V @ 1.0A

Simply plug a universal power supply (laptop style) into either of the barrel plugs on the 4HP panel. Connect your modules via flying-bus cables or the Bus Stick.

Daisy-chain multiple Row Powers to use a single power brick for multiple rows (typically 3-5 rows per power brick). Each row will be independently regulated and protected for ultra-low cross-talk between rows. Rows can also be hot-swapped (plugged/unplugged without powering the whole system down).

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

Frequency (F)

Frequency Modulation Intensity (FM)

Resonance (Q)

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

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

Notes: User-friendly mid/side processing module. Tweak the stereo image or split a stereo signal into mid and side elements then route out to other modules for further processing before summing back together. Powerful.

Supplier's Notes:
Minsk is a stereo image processor. It is a hybrid tool that combines digital and analog processing to facilitate advanced mid/side (M/S) manipulation of a stereo signal pair. It allows for separate treatment of the mid and side components, which affects the depth and width of the auditory scene. Minsk offers both manual and voltage control of the stereo width, as well as two dimension effects for enhancing the existing stereo image or creating a faux stereo image based on the stereo or mono input source. Minsk is especially handy during the preparation of a vinyl release or before a club concert, because it can eliminate out-of-phase low-end frequencies (high pass filter at 300Hz with the filter slope 12dB/oct, 50Hz with the filter slope 24dB/oct).

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.

Specifications:

Input signal level: up to 20V ptp
Output signal level: 10V ptp
Mixer GAIN: 1
Power supply: bipolar +-12V , eurorack standard
Power consumption: Eurorack PSU configuration: 160mA@+12V, 10mA@-12V
Module width: 12HP
Module depth: 25mm

Notes: The module can record the joystick movement up to a length of over a minute. The sequence remains stored in the battery-backed RAM after switching off. When playing the sequence, it can be manipulated in speed and playback direction.

There is a FREEZE function to hold the current joystick position plus an external reset input. In addition, a GATE is set during movement and a CV voltage is output as a function of the joystick movement. The ranges of the X / Y output voltages are bipolar +/- 5v or unipolar from 0 to + 10v. Both channels X and Y have a passive attenuator potentiometer, so that the voltage range can also be set lower.

Notes: 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: 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.

Notes: Alan (micro Turing Machine) Shift Register Based Sequencer

The randomness of the Music Thing Modular Turing Machine, shrunk down to 6HP. Alan retains all of the same functionality as the original including the connectors for the expanders.

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: A comprehensive solution for stereo signals in Eurorack, the Enhance 2 offers stereo and mid/side processing with tons of CV control. Balance, widen and sculpt frequency bands.

Supplier's Notes:
Moving from mono to stereo sound: a logical progression for any synthesist looking to expand their sonic palette. Making use of two audio channels, rather than just one, quite literally adds another dimension to the capabilities of a synthesiser.

Unfortunately, controlling stereo signals can be a challenge within a modular system. This realisation led to the development of Enhance 2: a convenient yet high-fidelity tool for stereo enhancement. It can be used to adjust balance, width and spectral content, while also opening up a world of mid/side processing; all under voltage control and in just 8 HP.

The primary stereo parameters are balance (moving the sound left or right) and width (making it narrower or wider). The balance circuit uses a true constant-power gain law, while the width stage allows for seamless transitions from pure mono to extra-wide stereo.

In addition, tone control is provided by a pair of unique, wide-ranging mid/side voltage controlled tilt filters with selectable corner frequency. These make 'cleaning up' a muddy-sounding mix straightforward, but also provide unique binaural effects when modulated.

Mid/side processing encodes the stereo signals into one containing only the mono material (mid), and another containing the differences between both channels (side). Apart from the internal tilt filters, mid/side outputs also enable external signal processing such as compression or reverberation. An integrated mid/side decoder returns the results back to standard stereo. And at all times, a LED bar phase meter ensures that phase correlation can be easily maintained.

Stereo field modulation, mid/side equalisation and beyond; Enhance 2 brings true analogue stereo control to the Eurorack world.

Notes: Part of Xaoc's Leibniz subsystem, which processes signals and voltages by manipulating binary 8-bit numbers, the Poczdam allows switching between two data sources.

Supplier's Notes:
Poczdam is a binary data routing solution for the Xaoc Leibniz Subsystem. It facilitates manual and remote switching between two Leibniz data sources, modifying individual bits of the data stream, and re-clocking the data with its onboard voltage-controlled wideband oscillator or any external clock signal. Poczdam is particularly useful within complex Leibniz setups where the user needs to reconfigure the data flow between multiple modules. However, it can also be employed in small creative patches, e.g., for waveform splicing, disrupting rhythmic loops, or generating digital chaos.
To better understand the device and avoid common pitfalls, it is strongly advised to read through the entire user manual before use.

Drezno is the input/output front-end of the system, consisting of an analogue-to-digital converter (ADC) and a digital-to-analogue converter (DAC), that alone can be used for manipulating analogue signals and voltages based on their binary representation.

Lipsk is a binary logic processing expander module that can flip (invert) individual bits of the digital signal representation. There are more Leibniz Binary Subsystem elements coming, with specialized and advanced sets of features.

Jena is a digital module that may be used as a flexible waveshaper for CV and audio signals, a wavetable oscillator, a Walsh function generator, or a rhythm generator.

Erfurt is a bi-directional digital counter, frequency divider. It has multiple applications: the output of the counter may be used as a phase source driving a digital wavetable, connected to other Leibniz modules it may scan waveshapes in Jena, produce stepped voltages useful for making interesting glissandi with Drezno and any VCO, generate gate patterns animating the spectrum of Odessa harmonic banks, spawn pseudo-chaotic sequences when fed back to Lipsk, etc.

Notes: Add external feedback loops, tilt filters and more to the Timiszoara effects module with this versatile expander. A must-have for Timiszoara owners.

Supplier's Notes:
Deva is an expander for Xaoc Devices' Timiszoara multi-fx module designed for creative exploration of the dirty/nasty side of signal processing. Deva opens up the Timiszoara programs you've come to love with some unexpected twists and turns along the way. The analog side features two external feedback loops (for the left and right channel) with tilt filters adjustable via sliders with two additional switches for choosing positive or negative feedback (for each channel). The third slider controls the DAC clock - from overclocking by a factor of two down to 16-times slower, so you can go from chipmunk to hardcore teeth gnashing of underclocked goodness. A switch allows for turning the clock control off for normal/regular operation. All features have inputs for external CV.

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.
