Synthesisers

Notes: A lovely creative approach to generative synthesis. Dual voices with triangle/square wave oscillators, shift register and envelopes can be patched via banana cables to create unique grooves and drones.

Supplier's Notes:
Double Knot v3

The Double Knot v3 is a small generative synthesizer with two voices and corresponding sequencers. This instrument has a simple architecture which is capable of a wide variety of sounds, including rhythms and drum patterns or textural and grating noise sounds. The interface is made up of knobs, switches, and banana plugs for patching. The two voices of this device each consist of a triangle/square wave oscillator, a shift register sequencer, an enveloper, and a voltage controlled amplifier. A clock sets the tempo of the shift registers.

The voices of the Double Knot are pre-wired, in a linear chain of functional blocks. The patch points are available to route modulations, influencing the simple linear voices. The game of this device is to investigate the relationships between the elements of the synth using the knobs, switches and patch-points.

FAQ

How many banana cables do I need? and what length?

8 or 10 cables around 12" long is a great start.

Can I patch this with my other synth?

Only what is safe for this synth. The banana ports of this device can handle max +/- 8V at all inputs and outputs assuming at least a 1k output impedance in the other device. The response range of the voltage inputs is ~1.2v - 8V (range of a TL07x powered by 9V).

Is this synth good by itself, or does it rely on other devices to be useful?

Some good sounds can be had using this device and a handful of banana cables.

Notes: An excellent combination of West Coast and East Coast synth philosophies, the Implexus features a complex wave generator and wave folder, analogue low-pass filter and sinkable LFOs and stereo delay.

Supplier's Notes:
The IMPLEXUS is a hardware desktop synthesizer combining west - and east-coast synthesis techniques into a single formfactor. The IMPLEXUS uses analogue waveshaping, folding and audio rate modulation to create a immense range of sounds and textures!

The IMPLEXUS is a performance-oriented musical instrument which will inspire you to compose music and explore its unique soundscape. The IMPLEXUS has a carefully designed analogue signal path with many unique ways to create intriguing sounds. The many sound shaping methods and modulation possibilities help you to create west-coast style harmonically rich sounds as well as thick east-coast analogue sounds.

The IMPLEXUS has a powerful "one-knob-per-function" interface with graphical feedback, utilizing LED rings to indicate modulators. The drone mode, tap tempo and looping envelopes let you explore the IMPLEXUS as a standalone sound generator. The MIDI and Eurorack compatibility and clock synchronisation options make sure it can be played in every setting. The IMPLEXUS is built to last. It has metal shaft potentiometers, an aluminium casing with scratch and solvent resistant graphics and an internal power supply (no adapter!). The IMPLEXUS is a characteristic, unique and complete musical instrument.

"West-Coast"

The characteristic sound of the IMPLEXUS comes from shaping and folding a sinewave, resulting in a complex waveform. The shaping and folding can be modulated at audio-rate in a single knob turn utilizing the second generator. Instead of subtracting you will be adding harmonics. After tweaking for a while you will be surprised to find out you didn't touch the filter... yet.

Unique filter design

The IMPLEXUS offers a 12dB/oct VCF with a unique analogue topology. This filter offers a lowpass and highpass mode. For cutoff modulation there is an envelope amount control with polarizer and a CV input on the back of the IMPLEXUS. There is an input mixer that has amplitude control over three inputs: complex generator, basic generator and the sub-oscillator.

Syncable delay

The IMPLEXUS has a stereo digital delay with dry/wet, delay-time and feedback control. There is a subtle modulation difference between the left and right channels to create a wide stereo image.
The delay can be synchronized to MIDI and external (modular) clock sources. Also the delay can be synchronized to Tap Tempo. For clock synchronization there are five divisions: 1/1 3/4 1/2 1/3 1/4.

Global pitch controls

The IMPLEXUS has a global pitch control section offering control over glide rate and pitch envelope amount. There is a dedicated vibrato LFO with manual control over amount and frequency.

Syncable LFO's

The IMPLEXUS has two LFO's with a variety of waveforms and multiple modulation destinations. The LFO's offer a wide range of 0.01 - 100Hz and can be BPM synced to MIDI and external clock. The LFO's can also be synchronized to Tap Tempo and can even be set in five different divisions.

Connections

The IMPLEXUS offers a 1/4" stereo balanced output. In addition to that there is a stereo headphone output with dedicated volume control.
There is standard MIDI input and thru over DIN and USB. Also there is a eurorack compatible patchbay on the back. This extends the sound and modulation possibilities of the IMPLEXUS even more!

Built in VCO tuner

There is a strobe tuner with 3 LED's on board, which lets you tune both the Complex and the Basic generator to a perfect "A" within just a couple of seconds.

A unique project by a small company

Majella Audio is a small company, and because of that, Majella Audio do most of the design and development themselves. The amount of hard work and effort that went into this project is what makes the IMPLEXUS a unique piece of gear with outstanding build quality. Majella Audio have created a few "How its made" videos to give you an insight into the design and development of the IMPLEXUS, which are viewable on their web page.

Welcome to the world of sound of LYRA-8, the unique organismic analogue synthesiser designed by Vlad Kreimer. "Organismic" means that LYRA uses some principles that lie in the base of living organisms. The way how LYRA's modules interacting between each other and the behaviour of the instrument resembles a live conversation.

LYRA-8 is based on eight generators, which will be referred to as voices. Their design is not like a traditional subtractive synthesis VCO. Instead of having a linear or logarithmic dependency on control voltage, they resemble the tone generators in old electric organs. Hence the use of the term "voices" instead of "VCOs". Lyra uses non-linearity a lot, and the voices are constructed in such a way that allows for non-linearity to express itself.

The voices are divided into four pairs (12, 34, 56, 78). All the pairs are divided in two groups, with two pairs in each (1234, 5678), creating tree-like structure.

The voices can function either in an electric organ mode or in an FM synthesis mode with each of the voices and its envelope acting as a separate FM operator. The voice's impact on FM synthesis will decrease along with the decay of its envelope.

LYRA-8 also has the next blocks:

The HYPER LFO is a complex low-frequency generator, whose waveform is synthesized from two simple LFOs by summation or multiplication of their frequencies. It also has a sync mode. The LFO can modulate the selected pairs of voices and the MOD DELAY.

The MOD DELAY consists of two lines of delay with cross-feedback and a special architecture that enables resonance between the two lines. Each line's delay time can be individually modulated from various sources, including external ones. The delay has a unique possibility of self-modulation where the output signal modulates the delay sample rate, creating cool effects.

The DISTORTION is last in the chain, after the delay. It enables the delay to also influence the distortion.

For all its experimental character, LYRA is a professional instrument. Its output dynamics and frequency response are balanced and ready for a live performance or studio recording without any additional processing.

Notes: Inspired by the RSF Polykobol, the mighty Kijimi is a serious analogue synth, packing eight voices of two-VCO architecture and SSI2140-based filters. MK2 upgrade features more powerful firmware, extensive LFO options and neat wooden end panels.

Supplier's Notes:
KIJIMI MK2 is crafted to be one of the most powerful polysynths ever built, all behind intuitive front-panel controls, from its continuous timbral variation to its exhaustive modulation matrix. The Black Corporation original features planetary-sized analog sound, inspired by the best of rare and classic synths, but unique to our own parallel galaxy.

Continuous analogue timbral control

Instead of fixed waveforms, KIJIMI's voltage-controlled oscillators can morph continuously through waveform types. Sine, triangle, sawtooth, and variable pulse waves are smoothly variable, with pulse width as you turn to the far right. It's a scheme that provides unique, independent timbral over each of the eight voices.

Deep 8-voice architecture

Each of KIJIMI 's 8 voices features 2 analogue oscillators each with a square sub-bass oscillator, for buttery timbres with extensive sound design options. The sub-oscillator produces an octave lower than the combined VCO1 and VCO2 outputs, meaning you can tune two sub-pitches. Hard sync is available in VCO sync and VCO1->2 and 2->1 configurations for maximum flexibility. There's also a noise source for adding bite and percussion components. A rich lowpass filter is built around the legendary 2140 chip and the ability to frequency-modulate it via VCO2, creates a full range of sounds from metallic and aggressive to subtle. Both filter cutoff and resonance are available as modulation destinations.

Unique envelope functionality with dedicated controls

Two ADSR envelopes come with independent rate multipliers, keyboard control of attack rate, and versatile routing. Engage the CYCLE button for a cycling trapezoidal mode, similar to that on vintage instruments like the EMS Synthi. Few polysynths offer this level of detailed control, let alone with front-panel controlsino menu diving needed.

Endless modulation programmability

Modulation possibilities set the KIJIMI apart from other polysynths. Two LFOs can be routed independently to up to eight destinations, directly on front-panel buttons, controlling frequency and waveform modulation, sub-oscillator amount, filter cutoff and frequency, and amplitude modulation. Each LFO includes multiple waveform options (sine, triangle, saw, ramp, square, random) and separate attack and decay knobs in addition to rate. ADSR2 sports four independent destinations, also via front-panel push buttons and knobs. Even velocity and aftertouch get their own dedicated control section for applying velocity or aftertouch to each parameter (LFO rate, waveform morph, sub, pitch bend, and VCA). Dedicated knobs let you apply your aftertouch and poly-aftertouch, to taste, right where you want it. You'll rarely use the menus, and when you do, it'll only be to unlock even more advanced functionality (like multiple LFO features!). KIJIMI is a rare case of fusing straightforward one-control-per-feature design with unrestricted possibilities.

Full MIDI and expressive control, tuning support

Combine all the elements, and KIJIMI is an instrument that's playable like no other. Each note you play separately triggers modulation, independently on each voice, with full control via aftertouch. Add in full MIDI control, complete MIDI polyphonic expression (MPE) support, advanced tuning capabilities (including microtuning via SCALA and 128 memory locations for tuning settings), and velocity polyphonic aftertouch, each with up to six more destinations with its own bipolar settings. KIJIMI finally brings a synthesizer architecture that can unlock the possibilities of your expressive controller of choice.

Updated package

The MK2 version of KIJIMI includes all the acclaimed sonic power and character of its predecessor, in an improved package. Updated firmware now includes the ability to assign different LFO settings (rate, waveform, envelope, and depth) to each individual destination. In addition to 128 factory and 1152 user presets, we've included user banks by Mathew Jonson, Richard Devine, and Paul Schilling. All this comes in a compact, 2.71kg/5.97 lb device with wood panels attached (or the option of metal rack ears instead). DIN MIDI and isolated USB are onboard.

Notes: No-nonsense analogue business here from JMT. Square wave VCO and sub-oscillators can be morphed and wave folded to create unique timbres.

Supplier's Notes:
The JMT Synth EWG is a desktop analog synthesiser with a wide-ranging VCO and two reconfigurable sub-oscillators that emit square waves, ideal for thick bass tones. Two adjacent knobs can control the pulse of the square waves, allowing for a wide range of tones and timbres. Two reduce knobs govern the leve of each sub-oscillator, allowing the user to blend the tones to their taste. The EWG-1 is powered by a DC9V center negative adapter or a single 9V battery.

Notes: Excellent polyphonic hybrid synth module from Michigan Synth Works, based on the Mutable Instruments Ambika. Six digitally generated voices are processed through a Polivoks-derived low-pass filter. Also available with Roland-style Shruthi SMR4mkII filter.

Supplier's Notes:
Xena is a rework of the legendary Mutable Instruments Ambika DIY synthesiser. Now fully machine assembled with an updated layout and an improved modern power supply. Available with all original 3 voice cards and compatible with 3rd part operating systems as well as a new AS3109 (modern reissue of the original Roland filter chip) filter

Xena Features:

6 voices with individual outputs, one Mix output (Mono)
2 digital oscillators per voice, with 36 oscillator algorithms/wavetables.
1 sub-oscillator, also configurable as a transient generator.
Pre-filter overdrive and bit-crushing effect.
Analogue 4-pole filter (or 2-pole multimode filter depending on the type of voicecard used) and VCA.
3 ADSR envelopes, 3 patch-level LFOs, 1 voice-level LFO.
Modulation matrix with 14 slots and 4 modulation modifiers.
1 arpeggiator, 1 note sequencer and 2 step sequencers per part.
Flexible mapping of the 6 voices. A single patch with 6 voice-polyphony, 6 independent mono parts, 2 layered patches with 3-voices polyphony, a 3-voice unison bass line on the lower half of the keyboard with a 3-voice unison lead on the upper half... all are possible!
MicroSD storage allows the storing of a life-long of patches, programs and multis, along with the history of editing operations for undo/redo.
Easy to change voice cards
Case size: 10.5"x6.5"x1.75"

Filter Options:

The device is available with the original 3 Mutable voice cards (more will be added later one). Mixing voice cards is possible but not recommended.

SMR Filter: This filter uses the same topology as the Shruthi SMR4mkII. It is a low pass 4 pole OTA-C filter. Its is a smooth "Roland-ish" type filter.
4P Filter: This filter uses the same core as the Shruhti 4-Pole Mission but only offers the LP4 output. The 4P filter is perhaps a a bit fuzzier than the SMR type.
SVF Filter: This filter board features a 2-pole state variable filter with low-pass, band-pass and high-pass modes. It is half of the Shruthi SVF Filter.
