Synth modules

Notes: Perfect for adding that final touch to a modular patch, the AJHSynth Finaliser R-EQ module includes seven Mono / Stereo reverb types, along with a four band equaliser and a Sonic Maximiser / Enhancer.

The Reverb, EQ and Maximiser can be used in Mono IN, Mono OUT mode or Mono IN, Stereo OUT modes. The reverb alone can also be used in Stereo IN / Stereo OUT mode too.

The fully analogue four band Equaliser includes three parametric equalisers for Low, Low Mid and High Mid ranges, and the High EQ has switchable shelving of either 2kHz or 5kHz. The Low EQ also includes a shelving mode.

The Maximiser is a fully analogue circuit too, with low and high treatment bands which change the phase and amplitude relationships of the sound to add punch and harmonics and really bring the sound to life in the mix.

The Reverb engine is based on 20 year old DSP technology, harking back to the reverb units which were used extensively on many synth and EDM tracks a couple of decades ago. We have added full control of reverb wet / dry mix, either manually or under CV control.

Notes: This 30HP wide module features twelve fixed frequency, inductor based bandpass filters, set at half octave interval spacing and covering from 125 Hz through to 5.8kHz. It also features low pass and high pass shelf filters, again they are fixed frequency and both are active inductor based circuits. It has a vintage pedigree that harks back to the original and highly sought after 914 Fixed Filter bank from the 1960's Moog 900 series modular synthesiser system, however we have brought this design up to date and made it compact enough to fit into skiff friendly Eurorack cases by using gyrator based active inductors, and have added some other very useful features too - the bands are split alternatively to left and right channels, each having their own individual output, and there is also an inbuilt Voltage Controlled cross-fader that allows panning between the left and right banks, with a mix of all bands available in the central position.

In addition, we have a second cross fader that can mix between the dry incoming signal, or an external signal fed into input 2, and this is cross-faded against the wet MIX Output - this allows Voltage Controlled crossfading from wet to dry signals, or between wet and external signals - and the level of each can be adjusted using the Input 1 and Input 2 level controls.

A further addition is the feedback control, this is similar in design to the resonance control on a regular VCF, but because of the multiple fixed filters topology it is rather different in operation - it would normally be added in small amounts to thicken up the sound, however we have allowed the feedback to traverse to quite extreme settings for howling feedback and even soft clipped self-oscillation, especially for the noise merchants out there...

Using L/C inductor topology bandpass circuits rather than the usual Sallen Key R/C active bandpass filters does give a slightly different sound and this is part of the magic of the original 914 filterbank, as the LC based circuit exhibits less phase shift against frequency that the more common Sallen Key R/C based bandpass filters that are used in many Modular synths.

Many people often wrongly assume that a fixed filter bank is exactly the same as a graphic equaliser - however this is certainly not the case, if all of the controls of a graphic EQ are set to centre then a flat frequency response is expected and the output will sound very similar, or identical to the input - this does not happen with a fixed filter bank, the frequency response rises and falls as it passes between each stage (but to a lesser extent than if the filters are all set to maximum output), so it acts as a soft slope comb filter, and the resulting output sounds very different from the input signal. Also, with all of the individual filters turned to zero there will be no output at all.

Notes: The Jumble Henge is a 16 input stereo spectral mixer with a unique patch-based mixing interface in a compact space. Each input has a carefully tuned resonant analog filter and a unique fixed pan value, providing each sound its own space within the mix. There is a Mix control to adjust the depth of the filtering and a clean external stereo input for chaining with another mixer or extra sound source. Jumble Henge is a space efficient solution for creating rich stereo mixes from a number of both mono and stereo sources.

INPUTS
Vertical and horizontal patch position determines a source's spectral and stereo placement in the mix respectively.

Aside from centred inputs, every input sits in its own unique pan position, helping to keep a separation between sounds but building a complete stereo image when combined.

The centre right inputs of the top two rows are normalised to the centre left inputs. - i.e if just a left input is patched it will be effectively panned center.

Towards the highs the panning becomes wider - as the human ear better pinpoints direction at higher frequencies, whereas the lows remain more centred for a tighter, more focused sound.

MIX CONTROL
Mix control for the overall depth of the filters applied to the inputs. Note: a slight volume increase occurs near the centre of the dial.

EXTERNAL INPUT
An additional clean stereo input pair for chaining with another mixer or additional source. Right input normalised to left input to accomodate mono sources.

OUTPUTS
Stereo mix output, the sum of all 16 inputs.

Jumble Henge was designed in collaboration with Worng Electronics and is based on the 'SoundStage'.

Notes: Stereo Strip takes the idea of a channel strip and makes it modular. By bringing this long-established component of the audio engineering world into the Eurorack environment and by adding CV control over its key parameters, you will find new, creative ways to use it in your patches!

It features stereo inputs and outputs for audio or CV with EQ, voltage controlled panning, stereo VCA, performable mute and input/output level switching for Eurorack or line level uses. Abusing the input level switching allows for some musical, modulate-able and highly shapeable distortion sounds too.

Stereo Strip was designed to be a creative part of a modular patch. Creating stereo images from mono sources, shaping and modulating existing stereo images, synthesising stereo pseudo ring modulation, sweetening FX with EQ or drastically wave shaping your oscillators, creating send FX routings with benefits or it can simply be used as a channel strip at the end of chain in a patch.

The addition of line level gain boosting (for the input) or reduction (for the output) allow it to work as a stereo input or output interface for external gear with the advantage of the VCA, panning and the EQ to shape the sound. Experiment with bringing external gear into the Eurorack format and then shape and modulate those sounds them on the way in!

Try patching Stereo Strip anywhere you would place a VCA in a system and/or explore its EQ and voltage controlled panning, which are rarer additions to the sound sculpting options for the Eurorack format.

Notes: The FUMANA is an all analog dual filter bank with various control to access dynamically these bands. Each filter bank is composed of an array of 16 independent 48dB/oct bandpass filters. Having two identical filter arrays, allows you to use one of those for spectral analysis (of a modulator signal) and the other for spectral re-synthesis (of the main signal). Each array is sub-grouped in odd and even bands (numbering these increasingly from 1 to 16 from left to right). It is possible to apply different signal to odd and even bands, both for main and/or modulator arrays. This, together with the 16 envelope followers connected to each band of the modulator filterbank, and the 16 VCA connected to each band of the main filterbank, allows the FUMANA to perform a single 16 bands or a dual 8 bands analog spectral transfer.

While the upper section provide access to each main filter's direct output, the lower section has 4 voltage controllable parameters to manage two independent functions for further spectral editing: tilt and parametric scan.

The tilt, as the name suggest, tilts the spectrum, adding and subtracting amplitude to the 16 bands, emphasizing lower or high bands, and attenuating high or lower bands: this is managed only with the green potentiometer.

The parametric scan, instead, works with three parameters: peak/notch, band selector and width. Like in a parametric equalizer, where is possible to set peak/notch gain, frequency and slope, the FUMANA uses three parameters to set which is the centre band to perform this manipulation, then if that band should be emphasized or attenuated, and how this action is extended to nearby bands.

In addition to the 16 bandpass outputs, there are other 4 outputs provided: the all bands output, the all envelope followers output, the odd bands and the even bands output. These two have the options to be inverted in phase with two switches, in order to obtain even more combination when summed together, maybe/also with the "all bands output", using, for example the 333 module.

Since a spectral transfer tool may be used as a "vocoder-like-effect", the FUMANA provides an input for an external noise which may be used for unvoiced (fricative/sibilants) sounds as words containing or starting with s, f, z, ch and other fricative sounds.

Notes: KR is based off of the concept of a guitar tonestack: you get a gnarly drive on the top and a super clean two-band shelving EQ with switchable midpoint after that. There are separate ins and outs, too, so if you want to EQ a thing and distort the other thing at the same time you can!

Kith Ruina's inspiration comes from the world of guitar amps. A drive into an EQ is an extremely common configuration for shaping guitar tone, and we find that it works extremely well for synths as well. A grungy drive into a pristine EQ gives excellent tone control, and with separate ins and outs for the two sections KR can be configured to fit into any patch you throw at it.

Notes: Polydactyl Versio is Noise Engineering's take on a multiband dynamics processor. Polydactyl Versio is equally at home on single-instrument timbral processing and on end-of-chain gloss. Taking inspiration from Noise Engineering's Librae Legio, Polydactyl Versio applies a unique and transparent algorithm across three bands for maximal dynamic impact. Add in a multiband saturation knob and noise gate, throw in a limiter, and you have a processor that gives ultimate control of color and dynamics.

Polydactyl Versio is part of the Versio family: this platform module can be transformed into a completely different effect by loading a growing number of alternate firmwares, completely free! Plus, with open-source support and documentation at LibDaisy, you can write your own firmware. Grab a Polydactyl Versio and process your signal into submission or total rebellion with three separate bands, saturation, limiting, and noise gating.

Notes: Versatile triple multi-mode filter with neat performance options, including individual outputs for the three channels, plenty of independent frequency control, a master shift control and lots of CV options.

Supplier's Notes:
Versatile triple multimode VCF capable of subtle to extreme tone shaping without losing the performance availability.

The three channels have dedicated outputs, as well as a mix output.

Multiple combinations of frequencies drawings are possible.

It was designed to create a movement to the sound thanks to the individual frequencies voltage control inputs.

Each channel is able to sweep through all the frequency spectrum.

A dedicated shift control with attenuverter cv input is able to swap all 3 filtres at the same time.

The Vibrazum shines at high feedback with 24dB slope, the resonance is well compensated and performative, even taking it to the extreme will not go out of control.

It sounds very "creamy" and full of rich harmonics from a gnarly tone-0shaping tool of sonic destruction, vowel robotic sounds, acid basslines, resonant percussive sounds and more...

Simple layout without compromising the wide range of sonic possibilities.

Notes: DRONX is a special mixer designed especially for the DRONE38 module; if has 6 input channels (so you can connect two DRONE38 modules) and offers some sound processing capabilities: A tone control with bass and treble control, a distortion, and finally a dual delay with different algorithms. Two insert points allow to add up to two more audio effects to the internal signal chain. Together with the DRONE38 module(s) you get a quite nice drone synth for dense, dark soundscapes.

Of course, it can be used with any other sound sources!

Notes: Three-band isolator with stereo inputs and outputs, splitting the signal into highs, mids and lows then allowing you to control level and frequency via CV for some clever sound sculpting and modulation.

Supplier's Notes:
Katowice is a stereo variable-band isolator that allows the user to manipulate a selected range of frequencies. It is the first module in a series of upcoming Xaoc Devices products designed specifically for processing stereo signals.

Katowice splits the stereo input signal into three bands: low, middle, and high. While the knobs and CV inputs define the center frequency and bandwidth of the mid band, the low and high bands are automatically adjusted so that the sum of all three is a complete signal. All three bands are passed through high quality VCAs and their stereo outputs are available separately for further processing. A stereo mixdown signal is also available.

Katowice may be used as a crossover network, a parametric EQ, DJ-style kill filter, or other band-selective applications, including multiband compression and stereo enhancement.
