Notes: Dual logic processor with chaining and CV functions

Affordable logic processing in this appealing little module from Klavis. Two independent dual-input processors offer a total of 15 different functions, with different options on each section.

Two dual-input sections can be used independently, put in parallel for 4-input wide logic, or chained for more advanced processing.

Each section presents normal and inverted outputs.

The two sections offer a set of common and specific functions for a total 15 different ones.

Several functions offer real-time CV control for dynamic changes of the conditions.

All time-related functions can be independently user adjusted and are saved automatically.

LEDs tell permanently the actual status of all outputs.

Functions offer features such as rising edge (rise) detection, falling edge (fall) detection, trigger delay, gate skip, gate to trigger and reverse, clock multiplication, clock division, set/reset, alternate right to pass, gate combiner with retriggering (Gater), majority vote, minus A AND B, and the usual AND, NAND, OR, NOR, XOR, XNOR, with up to four inputs when sections are combined/chained.

Notes: The Flexshaper is a highly versatile module when it comes to modify evolving voltages in other directions and levels.

Five settings allow you to fold/expand/clip/compress/invert partially or completely any CV or audio signal.

The module can act as an envelope-shaping tool, frequency multiplier, waveshaper, clipper, distortion, limiter, curve changer, and more.

Five CV inputs offer limitless control over the placement of the voltage points for dynamic signal sculpting.

Birth of the product

The idea of the Flexshaper comes from a feature in the Oberheimr Matrix synthesizers called Tracking Generator.

This signal processor was part of the modulation matrix and meant to be virtually inserted between modulation sources and destinations in order to change the shape of the controlling signal.

The Flexshaper applies the same concept using the same 5 shaping points. However, it goes beyond Oberheim's implementation on two main aspects:

It goes fast enough to process signals at full audio rate
The 5 points are dynamically adjustable (CV) in real-time
Besides, the Flexshaper can process adequately bipolar and unipolar Eurorack signals, even changing them one another.

Notes: Programmable Volt/Octave CV calibrator and transposer

Clever four-channel utility module designed to make it easier to achieve perfect oscillator tracking and transpose CV signals. Also includes some neat quantising and portamento features.

The CalTrans solves issues encountered when playing tonal music with a modular system: tracking problems, curves unrelated to Volt per octave ratio, limited octave range, cumbersome transpose, ...

The CalTrans corrects and expands the range of troublesome VCOs and brings V/Oct tracking to anything that oscillates.

Besides calibration, the CalTrans offers live play features. Each channel can be quantized and any combination of them transposed jointly.

A pair of rotary encoders with detent allow an precise selection of octaves and semitones.

VCOs whose tracking doesn't go high enough to follow the leader will see their pitch repositioned in their highest possible octave so that the global harmony is unaffected.

You can add a pinch of portamento and glissando to each channel and save the whole in user presets.

Firmware 1.17 offers:
* User editable input scaling to match sources that don't generate perfect 1V per octave signals.
* Complete rewrite of the main processing with higher precision.
* ... and the unavoidable fixes and tweaks ;-)

The updated user manual 1.4 is much expanded with operations described in exquisite details :-)
.. and a version 1.5 corrects a mistake in the input calibration description and eases the reading elsewhere.

Notes: The Quadigy is a complex envelope generator focused on live play.

The goal is to allow the user setting up rich, interactive and dynamically evolving envelopes without the risk of breaking up a subtle and intricate patch once on stage.

This is achieved by offering two main modes, one where full control is available and a Live mode where only the settings that are sensible using on stage are accessible.

The user interface offers an intuitive access for otherwise complex settings.

Advanced features such as automatic time-stretching, multiphase clocking and full morphing put the Quadigy in a category on its own.

Notes: Mixer & CV/clock-controlled Switcher

Focused versatility seems an oxymoron when describing the features that led to the design of the Mixwitch.

With only a pinch of mixing, inverting and controlled switching, Klavis Electronics brew up a plethora of combinations and uses.

This is voltage processing magic!

The Mixwitch design comes from a frustration with attenuvertors (bipolar attenuators-inverters) whose off (neutral) position is difficult to retrieve, especially in live situations.

Klavis went for a digitally-controlled analogue path where polarity inversion would be at the touch of a button. So, the usefulness of attenuating/inverting can be realized by turning the pot down, swiftly pressing the inversion button and reopening the level. The zero level is where you expect it, with the pot full down.

Once a clean polarity control was established, a mute function was added, offering the benefit of pre-adjusted pot settings ready to be activated at will.
The next step was to bring something extra, useful and creative. There are plenty of analogue switches controlled by a clock; but arbitrarily selecting an input with a voltage is less known. Having both control capabilities combined with Klavis' specific mixer features creates a unique fusion: welcome to the Mixwitch!

Notes: The Man-Machine Interface, or MMI, is a passive touch and pressure sensitive controller which allows the user to direct CV and audio signals at will. The MMI consists of three input/output jacks, and five body contact surfaces in glorious gold.

The zig-zag body contacts correspond to the input/output jacks, with the top zig-zag connecting to the top jack, the middle zig-zag connecting to the middle jack, and the lower zig-zag connecting to the lower jack. The spiral patterns in between the zig-zags are comprised of the two adjacent jacks, so the upper spiral is comprised of the upper and middle jack, while the lower spiral is comprised of the middle and lower jack.

In order to operate the MMI, the user can touch any two points with their fingers, patch cables, a piece of fruit or vegetable, or any other conductive substance or object, in order to complete the connection. The degree of contact made with the MMI, and the resistance of the object completing the circuit, will determine the output that is sent along the circuit. For instance, if a user were to patch a VCO into the top jack, and patch the MMI into a filter in the middle jack, the VCO will be sent to the filter when the topmost zig-zag and lower zig-zag are connected by two fingers, for instance.

But how about the spirals? The spirals offer a way to make a connection with one finger. Using the example from before, the connection will instantly complete when the user touches the upper spiral pattern. Using this principle, it becomes possible to use the MMI in unusual and interesting ways, such as a rudimentary keyboard, a drum controller, a switch and any other number of weird and exciting purposes.

It is also possible to combine several MMI - using two different MMI, it is possible to reach across one zig-zag to another zig-zag, in order to make a different connection, or to place a particularly long vegetable across all the contacts just to see what will happen. The MMI is an unusual patching system for the experimental musician, and lends itself well to all manner of experimentation and weird instruments.

The MMI can bleed a tiny bit of signal when using sharp VCO waves like square waves, while other sounds like sine waves will have softer responses. This can easily be corrected with amplification or attenuation as needed.

The MMI takes up 4HP and is skiff friendly, and is also suitable for installing in external boxes as a passive control unit. You can combine any number of MMI to create increasingly complex keyboard-like arrangements, drum pad matrixes or advanced switch systems.

Meridian is a 14hp dual multimode filter array, designed to offer users a choice between 4 selectable filter types per side and 4 selectable filter modes per side, plus 2 effects (drive & phase shift) and the ability to be pinged. This allows users the flexibility to easily create a range of sound textures and sonic landscapes using a single eurorack filter module.

The name Meridian represents the idea of a meeting point or a convergence of different elements. Filters are often used to blend, shape, and refine different sounds into a cohesive whole. Meridian is often represented through the idea of a barrier or a line that separates parts. This concept mirrors the way the filter delineates different frequencies and aural elements, generating a defined contrast that shapes the overall sound.

In context, the name Meridian conveys a sense of balance, harmony, and unity, while also suggesting a clear and definitive separation between different sonic elements. Similarly, Modbap Meridian allows the use of two selectable, mixed or matched, filter types and two selectable, mixed or matched, filter modes to reshape and refine the source material into new cohesive textures. Meridian's two filters, each have independently adjustable cut off, resonance, and contour parameters. The Prime Freq control is the center macro control of both filters in tandem. The module
boasts a dynamic control feature aptly-titled 'Ping'. Activation of Ping is enabled through the Ping input. Additionally, the filter permits selection of serial or parallel routing configurations and is capable of functioning as either a stereo system or two independent mono channels with the press of a button.

Meridian boasts a selection of filters (including Ladder, OTA, Comb, and vocal formant) to generate a vast range of textures. Its sound shaping capabilities are furthered by its two distinctive and characterful effects: Phase Shifter and Drive.

All of Meridian's key features can be modulated via CV inputs. For instance, synchronization to tempo can be achieved with the clock input, allowing for clock synchronized Phase Shifting. As is typical of Modbap modules, Meridian was designed with tweak-ability and performance in mind.

Dual Balanced ins and outs for the studio or the road. Interface your rack with the balanced line level world; send and return to pedals or desktop FX units; patch in and out of your DAW, external synths, drum machines and other line-level instruments.

Get Connected

Audio I/O (2023 edition) allows you to effectively interface your Eurorack modular system to the balanced line-level world (+4 dBu). You can send and return to rack mount/desktop fx units, patch to external line-level instruments like synths and drum machines, interface to a DAW and much more.

The 2023 edition moves the TRS jacks to the top of the panel

The rear-mounted 3-pin CHAIN IN connector allows you to sum (in parallel) other audio sources to go from Eurorack level to the BAL LINE OUTPUTS. This could be from modules like the Mixup 3U, Xfade 1U, Stereo Mix 1U, and XY I/O 1U. You could also use this to connect with the 3-pin headers on the Palette and 7U cases audio i/o boards.

The rear-mounted 3-pin CHAIN OUT connector allows you to directly connect the level-shifted BAL LINE IN to the inputs of other compatible devices such as the Mixup 3U, Outs 3U, Stereo Mix 1U, XY IO 1U, and Headphones v2 1U. You could also connect the to the TRS jacks of the Palette and 7U cases audio i/o boards.

Features:

2 x Balanced TRS 1/4" to Eurorack modular level input paths
2 x Eurorack modular level signals to Balanced TRS 1/4" output paths
4 x six stage analog led VU meter to monitor all inputs and outputs simultaneously
Input path has up to 20 dB of gain, which allows you to patch in low-level consumer level signals and boost them.
Output path steps a nominal Eurorack level (10 Vpp) down to +4 dBu with up to +6 dB gain

Notes: Take a DJ-mixer-style combined high-pass and low-pass filter, cram it into Eurorack and you have the DJ VCF. A simple formula, but one perfected by Erica's attention to detail, with CV control and adjustable resonance.

Supplier's Notes:
As its name suggests, the Erica Synths Black DJ VCF provides sound treatment functionality typically found on DJ decks - it is fully open when the cutoff knob is set to 12:00. When turned counter-clockwise, lowpass filtering is applied and when turned clockwise, highpass filtering is applied. The filter also has a nice-sounding resonance parameter. This module provides hands-on control over the sound during the performance, as well as unconventional timbre modulations that are hard to achieve with conventional state variable filters. The Black DJ VCF is a fully analogue design and consists of two VCFs - highpass and lowpass in series and the filter management is done by complex CV routing.

CUTOFF
This is the main control of the module - manual cutoff frequency adjustment with a twist - it's fully open when the cutoff knob is set to 12:00. When turned counter-clockwise, lowpass filtering is applied and when turned clockwise, highpass filtering is initiated

AUDIO LVL
Adjust the audio signal level

RESONANCE
Adjust the resonance level manually. On settings over 1PM, the filter will start to self-oscillate. The resonance is incoming audio signal-sensitive - a signal of greater amplitude may reduce the impact of resonance on the resulting sound

CV1 LVL
This is the cuto CV attenuverter. Adjust the CV level to your taste! Notice that the cutoff CV works differently compared to conventional state variable filters - it sweeps the filter from closed lowpass through fully open to closed highpass

CV2 LVL
This is another cuto CV attenuator

CV2 IN
This is the cuto CV2 input, which is controlled by the attenuator knob

AUDIO IN
Patch your audio signal here.

Notes: Describing Univer Inter as merely a MIDI-to-CV module falls short of its immense potential. It serves as an all-encompassing MIDI-to-any-format converter, elegantly packed into a compact 6 HP unit. Connect to your gear via USB B or TRS MIDI, or use the included adapter to plug straight into those 5-pin DIN connecters we all know and love. Whether you're looking to map clock, note, CC, aftertouch or something else that MIDI can encode, UI can do it: we built in over 20 settings for each of the 8 outputs.

Want to control a pair of monophonic voices, complete with velocity and aftertouch? No problem. How about a polyphonic setup, with gate and pitch per voice? Easy. Need to synchronize an in-the-rack sequencer with your DAW or a MIDI clock? UI has you covered.

Eight outputs isn't enough, you say? Chain two UI together via their front-panel MIDI ports and a TRS cable for 16 - you read that right, 16 - configurable CV outputs from a single MIDI connection. The possibilities are endless.

Noise Engineering also made configuration simple via the front-panel USB connection and the easy-to-use Univer Inter section on the Noise Engineering Customer Portal. Go wild and set each channel to any output option you need, or just use one of our simple presets. Configuration files can also be saved as sysex files for easy backup and sharing.

Notes: The Z2040 is TipTop Audio's redesign of the most famous analogue filter from the polysynths of the 80's and features Tiptop Audio's signature lush, big, and creamy sound. Its frequency sweeps make thick bass lines and leads with great dynamics. When modulated with audio frequencies through its various inputs, the Z2040 gets quite colourful and is capable of creating many new sounds and textures as the forces of the incoming waves and their harmonics blend through the filter's non-linear circuit. When set with Resonance feedback fully up, the Z2040 transforms into a pure sine-core VC-Oscillator, great for making snappy percussive elements and whistling sounds.

A look under the hood will find that the heart of the Z2040 is a discrete design 4-pole low pass filter with a core similar to that of the SSM2040 filter chip, used in the 80's Prophet 5 Rev 2 synthesizer, and its brother the SSM2044, used in the famous early EMU samplers and PPG synthesizers of the 80's. Both filters are considered by many to be, "the best sounding filter ever".

The Z2040's four modulation inputs are built to handle CV and audio signals, enabling deep modulation of the filter core and passing signals. A VC resonance input is provided to modulate and even clip the sine wave produced by the filter feedback loop. A Frequency Modulation input (FM) provides dynamic filter sweeps and the unique VC-FM index allows modulation of the incoming FM signals. On top of that, the Z2040 comes with an audio VCA that can be configured to act upon the input or the output of the filter.

Notes: DADA is a dual, full-featured vca and saturator. The top and bottom halves are identical. Features include:

· inverting and non-inverting inputs (summed).
· Exponential control input (unipolar).
· Linear control input (bipolar).
· SYMMETRY control (input offset).
· Initial gain setting.
· Dual bicolour led level indicator. Each indicates either the positive or negative going portion of the signal.

Saturation begins to occur once the output amplitude surpasses 5 volts, and increases between 5 and 6 volts. Beyond 6 volts signal amplitude, the output moves beyond saturation into full distortion.

The led scheme is as follows: green indicates a clean signal, yellow indicates saturation, and orange is distortion.

Input attenuators on the control inputs allow you to dial anything from clean to clipping.

AXON-2 is an 8HP expander module for the SQUID SALMPLE, MFX and Pamela's PRO Workout that like the AXON-1 provides 4 additional freely assignable CV inputs but additionally adds manual offset controls and 2 additional 'performance' buttons.

The addition of AXON-2 increases the Squid, MFX or Pam PRO's total number of CV inputs by 4, greatly increasing the possibilities for vast modular manipulation. Each of the CV inputs includes an offset for hands on control over parameters assigned to CV. Per assignment digital attenuation and offset via the host module is also available for fine tuning the modulation or control over parameters.

The AXON-2's large buttons are great for controlling select functions in a live performance environment or adding convenient quick navigation shortcuts when making edits. The buttons functionality and assignability are dependent on the host module. See respective manuals for details.

NOTE: AXON-2 support requires the latest firmware be installed for Pam Pro (120 or newer), Squid (187 or newer) and MFX (105 or newer).

Notes: Lattice is a 16HP 12-step sequencer composed of a 4x3 grid of steps that can be
navigated horizontally, vertically or sequentially from step 1 to step 12. Sending a trigger
into one of the 3 progression inputs will move the sequencer forward a single step. This
will result in a 3-step, 4-step or 12-step sequence depending on the input used. The

Notes: Hike is the new 2 - channel envelope generator from Tenderfoot Electronics.

Each channel has 3 main modes:
Red = Looping envelope 0V to 8V
Green = One-shot triggered A/D envelope
Yellow = ASR envelope for use with longer gate signals.

Each channel has separate mode buttons, rise and fall knobs, as well as additional CV control over the rise and fall.
Each channel has an attenuator to dial back the 0V to 8V output.

Holding the mode button puts the channel into random voltage mode and acts similarly to a sample and hold circuit.
The 'rise' knob alters the rate at which the sample triggers occur.
the 'fall' knob adjusts the level of randomness from one sample to the next.

Min Times:
Rise: 3.5ms
Fall: 6ms

Max Times:
Rise: 6 seconds

Notes: The new SVF-1 from Tenderfoot Electronics is a great sounding state variable filter with voltage controlled cutoff and resonance. The SVF-1 self-oscillates when the resonance is turned up and has a 1V/octave input for use as a sine wave VCO.

The resonance circuit includes a Q control, a drive control, and a button to press if you're feeling less polite and really want to push the resonance beyond its limit and get it sounding dirty! The Q control is also controllable via a CV input jack.

All outputs are available simultaneously:
Low Pass
Band Pass
High Pass
Notch

Notes: WAYOUT8 is a patchbay module for Eurorack systems used to group your DAW inputs and outputs, or manage signals going from one case to another. Wayout8 is grounded, meaning that even if nothing is plugged into the inputs your outputs are still grounded and will not pick up noise. The module is made so it can be mounted two ways, with outputs on the left or right, whichever is the most ergonomic placement in your case. All eight channels are passive so they do not modify your signals and can be used for audio and CV Gate. No power is required.

Notes: BaxandallEQ is a 3-Band EQ equalizer with two individual channels on board. Gain of each of its bands (bass/middle/treble) features a i15dB range. Internal routing of the circuit of the module is a modification based on the legendary EQ design from 1952.

It was never easier to treat your mono/stereo system or external instruments, whole mixes with a touch of this precision equalizer that allows you to dial in any sound from 1950's onwards. Konstant Labs' design is based on the fairly popular and now famous work of renowned electronics designer Peter Baxandall who designed one of the world's most popular EQ curves to date. Why are they so popular? They improve on any source signal you process/send through them.

Konstant Labs decided to base their next module on one of Peter Baxandall's renowned circuits that stood the testament of time in various tour applications and studio rigs all around the world and make it available for the eurorack modular format, while also improving upon its premise and foundation.

BaxandallEQ is a 3-Band EQ equalizer with two individual channels on board. Gain of each of its bands (bass/middle/treble) features a i15dB range. Both of the featured channels can be used independently (stereo) with individual gain for each band or as a one big massive single channel with staggering +/-30dB of gain on each band. Internal routing of the circuit of the module is a modification based on the legendary EQ design from 1952.

This highly sought after EQ circuit is being used for well over 70 years for processing audio, mastering in many high-end studios as well as home studios and home radios all around the world. Konstant Labs took the original circuit and its bass/treble section and modified it to feature a defined and sound-rich middle range. The premise was to deliver a convenient way how to treat your whole eurorack modular system with some precision EQ processing without compromising on sound, high-quality components, and materials. All-analogue signal path features only the best hand-selected condensers from WIMA and high-quality/low-noise opamps to deliver the best sound possible without any unwanted artifacts. The whole circuit and its components reside on one PCB which allowed Konstant Labs to keep high-quality/high-performance sound without increasing upon modules depth.

There is a switch on the back of the module that allows you to set the overall gain of the module - either 0dB or +6dB if desired.

BaxandallEQ offers you a broad range of applications for your modular system and external instruments alike. It pairs exceptionally well with Konstant Labs' high-quality stereo mixer module PanoramaMIX and M2S (mono to stereo converter module).

It was never easier and more affordable to add a slight touch of precision, eliminate unwanted frequencies coming out from your eurorack modular patches, add raw analogue power to bass drums, snares, claps, percussions, or glue whole mixes together. Simply feature BaxandallEQ in your signal path and watch the magic of sound reminiscent of the vintage era unfold right before you.

Mult9 is a very handy basic passive multiple module. It contains 9 jack sockets in 2 HP.

You can use it to split any signal (clock, gate, trigger, DC or audio) in multiple ways and directions, according to your patches needs. You can use Mult9 for one or two input signals in three working modes:

1) If you connect input signal to any jack except no.5, copy of the signal will be on each jack except no.5.
2) If you connect input signal to jack no.5, you split Mult9 to two sections into two different input signals. The first section will be jacks no.1-4. Second section will be jacks no.5-9
3) If you want to use all 9 jacks for one signal (no.5 jack included). You have to connect solder jumper J1* on the bottom side of the module. It is easy, just use solder iron and solder wire to solder two points of jumper together and you are good to go.

Panel is made from high-quality CNC milled anodized aluminium.
