Notes: Jackson Audio presents the TWIN TREM, a pedal that features two distinct tremolo effects: a Harmonic Tremolo on the right side and an Optical Tremolo on the left side. Each tremolo is equipped with independent Speed, Depth and Volume controls and can be used separately as stand-alone effects (or combined) to create rich, unique and percussive sounds.

Each tremolo side has different LED indicators (red for Harmonic, blue for Optical and magenta for Combined). These LEDs also visually display each section's speed, making it easy to sync the two tremolos together.

The TWIN TREM boasts four top-mounted jacks, allowing versatile signal routing. You can run it like a standard pedal, routing the signal in through the first jack and out through the last. Alternatively, you can route the signal through the Harmonic side first, pass it through a reverb or another effect, and then into the Optical side, preserving the classic placement of optical tremolo after reverb, just like in many amplifiers.

These routing options opens up endless possibilities for integrating the TWIN TREM with other effects in your signal chain. If you have a stereo setup, the right side can run through the Harmonic tremolo, while the left side passes through the Optical.

In addition, offering comprehensive control over pre- and post-effects tremolo placement all helps to make the TWIN TREM an essential tool for building a complete rig.

Notes: The original Diamond VIBRATO was conceived in late 2006 with a simple yet ambitious idea: crafting an analogue, true-pitch Vibrato pedal, built around the revered MN3007 bucket brigade chip and promptly became one of the world's most coveted and sought-after Vibrato pedals.

Now, nearly two decades later, the new Diamond VIBRATO is not only back - it's better than ever. This latest and greatest version of the VIBRATO incorporates decades-worth of end-user feedback, better tech, maximum efficiency, modern features, a meticulous redesign for enhanced player experience and the signature Diamond quality that made the original pedal so great.

This reinvented and coveted classic is now available in an updated, compact package, plus the first run of 800 pedals is equipped with NOS Panasonic MN3007 BBDs.

Half the size, all the sound

Don't let the size cause you to underestimate the power packed within. We've managed to stuff all the VIBRATO's analogue audio path, Compandor and BBD Delay circuits in pedalboard-friendly sized enclosure. By using dual stacked PCB's, we've not only optimised space but also enhanced the isolation of the audio path from the power and switching circuits. Add top jacks, soft-touch True Bypass switching, and standardized negative-centre 9-18 V DC input with polarity and over-voltage protection for a bulletproof pedal ready for any gig.

Analogue BBD delay line

At the heart of this pedal lies the revered MN3007 Bucket Brigade Delay chip, renowned for its ability to create the rich, organic, and warbling Vibrato & Chorus tones which make the sounds of the 70s and 80s guitar icons. The MN3007 infuses its signature character to your guitar signal-delivering a natural, liquid-like pitch modulation with a rounded vintage texture and mojo that is missing from modern digital counterparts.

Compander magic

The Compandor Circuit adds warmth and complexity by controlling your dynamics. Acting as both a compressor and expander, it not only gives the VIBRATO its signature feel and response but also reduces much of the noise inherently found in BBD technology. Borrowed from the Memory Lane Jr., the updated compandor design in the VIBRATO provides increased clarity, less distortion and is pre-trimmed therefore will never have to be recalibrated.

Input voltage

While the original VIBRATO could only be powered by an 18 V DC reverse polarity power supply (internally regulated to 15 V DC) - the new VIBRATO offers a much more versatile 9-18 V DC operating range. The voltage is internally regulated based on the power input and as a result, the pedal will sound slightly different depending on operating voltage as the clock frequency will shift.

For classic, pristine and lush Diamond VIBRATO tones with added headroom, power the pedal at 18VDC like the original. Powering it at 9 V DC will add a bit more colour and warble - much like the "High Mode" in the original big-box VIBRATO. You can take advantage of the added range or just dial back the depth. Better yet, grab a Cioks power supply and try it at 12VDC or 15VDC regardless of what you settle on, the Diamond VIBRATO will sound great! As always, it is recommend that you use a good quality, isolated power supply.

Notes: In only 12hp, Axis condenses all the classical blocks for the audio amplitude management, redefining the classical envelope -> vca -> mixer path. The idea is to manipulate a sound over three axes: its length, its volume, and its place inside the stereo field.

Axis is a dual envelope generator that features an integrated VCA, a crossfader, and a voltage-controllable mixer section. The initial concept was to combine digital control over an analog VCA to closely emulate the classic Vactrol sound. After more than a year of refinement, Axis has evolved into more than just that. It offers exceptional versatility, providing a wide range of waveforms and the unique capability to simulate the natural percussive qualities of different materials. All this is in a complete analog path.

For the function generator section, we choose a faster method over the classic AD/ ADSR style: a selection of waveforms studied to give back a precise musical effect can be selected with the shape knob. The function length is independent from the actual wave shape and can be settled with the fader timeX from 30hz to 15 seconds. Also, setting the timeX fader at its maximum level will leave the VCA open.

A more typical collection of envelopes can be found in the first half of the dial. All kinds of sounds, from plucked notes to long volume swells passing through lead-friendly lines, can be obtained here.

More unusual, the last section of the knob is thought to simulate the acoustic vibration of a percussed object. Starting with a triangular envelope, from this point on, the more you turn the knob, the more rebounds will be added, simulating the natural ring of a material. Using this section at low rates can generate complex envelopes that could also be suitable for the vibrato-style AM effect. The envelope generator section includes a mode switch (cycle,trigger,hold), a trigger/gate input, an EOC trigger out, a function output, a CV for the envelope shape selection, and one CV for time.

As a cherry on the cake, a crossfader is placed at the end of the chain, blending both Axis halves. With a dedicated fader and CV control, raising it will invert the L/R output, creating nice stereo effects or moving the voices around the stereo field.

The VCA section is more straightforward: it has an audio input/output[1] and a VCA CV input[3].

You can plug the audio I/O to use Axis in its completeness and eliminate a lot of cables and mess!

Soundwise, here at Clank, we are all about vactrols LPGs, but since we knew it's not the most versatile option on the market, we came up with a different design. Blending together a VCA with a not-so-step filter, we obtained a VCA with a nice mild LPG flavor: enough to sound not so "clicky" but not too slow to inficiate really fast sounds.

By default, the envelope created by the function generator is normalized to the CV in of the VCA. Plugging a cable into the VCA in breaks the normalization, in this way you can use a different source to control the VCA and free the function generator for LFOs or modulation duties.

The range Y fader sets the strength of the envelope, but you can also see this control as a volume fader, which is nice since you won't necessarily need an additional volume for your voice after the Axis. Take into consideration that since the Axis VCA is actually a low-pass gate, lowering the rangeY fader also affects the cutoff frequency. The range fader also has its CV control to program dynamic changes to the sound. Basically, it's a VCA over a VCA that permits every note to be at different intensities. Last but not least, Range CV can also be fed by a unipolar modulation CV to obtain vibrato effects or audio rate AM modulations

Notes: Sibilla is a DSP digital stereo oscillator that aims to translate into music the beauty and harshness of a semi-barren mountain. Its sound is sculpted by various saw and sine waves running through intricate delay networks, altered by LFOs, white noises and creating constructive and destructive interferences.

Both stereo channels are the output stages of two feedback audio loops.

Each loop is made up by a main sub sinusoidal wave oscillator and two saw and sine waves with frequencies affected by the generation of harmonics (right channel) and subharmonics (left channel). All waves have different phases whose offset is constantly affected by minor variations created by two pairs of grains randomly fluctuating within the waves amplitude spectrum and being sampled at a certain speed.

Waves then meet to each other to a common point, together with two white noise sources, creating constructive and destructive interferences constantly affected by two LFOs movements.

Interferences are then run into a resonant low pass filter and then distributed to four different delay lines from which they are fed back into the audio loops at different time intervals depending on the grain's movements.

Notes: Chaos is excellent for modulation purposes or as a clock multiplier/ divider, but that's only scratching the surface... It takes a different approach to writing sequences than traditional sequencers, as it is built on six touring machines combined with an effective pattern and clock generator. One of the biggest challenges in electronic music production, especially when it comes to sequencing, is finding that sweet spot between hands-on control and possibilities.

It can be frustrating because many sequencers with lots of fun and playable controls don't always pack the punch you need. On the flip side, you have those bigger menu-based sequencers with tons of options but can feel overwhelming with all the programming they require. It's designed to help you overcome these challenges and make your music-making experience smoother and more enjoyable, whether you're jamming or writing a song you want to execute live.

Typically, a sequencer starts with a blank canvas. However, with Chaos, you begin with all possibilities at your disposal and can easily narrow them down to fit your vision with just a few adjustments. This makes creating a sequence that conveys a specific mood quick and straightforward. Once you have established this initial mood, you can loop it from the last step to step 32 whenever you hear something you like. At this point, you can choose to modify the entire loop or adjust the parameters of any individual step. There is no need for extensive menu navigation; simply pressing a button and turning the encoder gives you control over parameters such as gate time, gate probability, gate width, gate ratcheting, gate swing, notes, scale, slew, and slew amount.

The LED bar continuously displays the voltage output of the selected channel, as well as the gate and each parameter's value, eliminating the need for a screen. You can save and recall the entire sequence of its six channels at any time. Additionally, there is an internal function that allows you to randomize all parameters or just a select few within a specified range, helping you discover new melodies to work with.

Chaos is an endless reservoir of tunes and is incredibly quick and powerful for composing sequences, gate patterns, or modulation. In a short time, it will become the brain of your system.

Six CV outputs can be used for a wide range of applications; everything from chaotic modulations to fine-tuned sequences can be obtained. Thanks to its interface you can quickly adjust the voltages from where the random engine picks new values and then edit them in every aspect.In addition, Slew amount, Quantization, and external sampling are available on every channel.

Thanks to its 6 gate outputs, Chaos can be used as your system's quick and effective clock manager and gate pattern generator. Chaos also provides a stable master clock (10mS to 10Sec) from a separate output and can be clocked from external devices. On every channel, you can set Probability, Width, Swing, Ratcheting, and Time as a multiplier/divider of the master clock or unquantized in mS.

You can freeze the last 1 to 32 steps of randomly generated CVs and Gates in a locked loop when you hear something you like. Loops are not static; every parameter of Chaos can be used again to change the loop behavior in a non-destructive way.

Entering sequencer mode means taking control of every aspect of the looped sequence generated by the random engine. You can change time, width, probability, ratcheting, slew, slew amount, note, note deviation, etc., for each of the 32 steps of all six channels.

Thanks to the external input, you can substitute the random generator with external voltages, transpose a sequence on the fly, and a lot more.

If you're more into generative stuff or want to add a bit of craziness to the patch, you can use the Chaos function to randomize all the parameters on a channel. A sophisticated control named entropy is available on every parameter to set the distance of the new value from the last one.

Chaos can save and recall 10 slots where you can save entire sets or preferred channel behavior. Recall can also be done with an external voltage.

Notes: The Garden Listener is a random control messages generator from biometric signals. It detects conductivity variations on living beings' surface and transforms them into MIDI notes, ranging from C-1 to C8, and CV signals (0 - 5V). Its behaviour can be tamed through the one-knob menu from which you can choose and modify:

probes' sensitivity (making it more or less sensitive to current variations);
scale (chromatic, major, minor, Indian and Arabic);
MIDI channel (from 1 up to 16);
LEDs' brightness.

Conductivity variations are detected by the Probes Input and converted into MIDI notes in real time according to the Main menu settings. Each MIDI note exits through the MIDI output, allowing you to take advantage of the sound of either any synthesizer equipped with a MIDI port or any VST in your DAW, and gets converted into an analogue signal.

Trigger and Gate are fired every time a new note is generated, their voltage output can be modified with the respective attenuator (0 - 5V).

All the MIDI notes are converted into variable voltages (0 - 5V) depending on their pitch and exit through the CV output (1V/oct).

The CV output behaviour can be modified via the Octave Selector which acts as a "CV equalizer" from which you can choose to generate CV only if the respective MIDI note lies within a certain octave range.

For once, leave those LFOs alone, and let any living conductive being modulate your signals.

The module comes with 3.5mm white probes and a set of snap-on adhesive reusable electrode pads. A MIDI-TRS type A adapter (not included) is required for the MIDI output.

The module requires calibration for a proper 1V/oct output.

Notes: At its heart, Alpha Pro is four identical VCAs, each with overdrive and stereo outputs. However, it's also possible to link any of the VCAs together to form a voltage controlled mixer. This flexibility allows Alpha Pro to replace a bank of VCAs, sub-mixers and even your output mixer.

Each VCA has two Signal inputs and a summing mixer with individual attenuators.

There are two mix buses, allowing each VCA to act stand-alone or as part of the mix. So you can configure two separate sub-mixes, with any of the VCAs contributing to the mix, or use all channels to make an 8 input, stereo output main mix.

The VCA gain is controlled by the Initial Gain knob, and two Gain CVs - again mixed together, each with an attenuator. Having two Gain CV inputs allows for more complex modulation possibilities without needing another CV sub-mixer.

Gain response can be set to exponential or linear.

The XING switch enables zero crossing detection to prevent clicks on very fast CV inputs.

Two drive modes are available, a soft clip and a harder fuzz, with the DRIVE control increasing the gain into the overdrive circuit to increase the effect.

The VCA output is stereo, with manual and CV control of pan - again, with an attenuator.

Alpha Pro is available now as a 'founders edition' which includes the Alpha Switch as standard.

Notes: Foxtrot is a quad, multimode virtual analogue filter with three different classic filter types.

Each of the four filter channels can be:

1) A ladder filter, based on the classic MOOG designs from the '60 and '70s
2) A Sallen-and-Key filter based on the Korg 35 module used in the MS-20
3) A State Variable filter as used in the Oberheim SEM

Each filter type produces Low Pass, Band Pass and High Pass responses which can be morphed between using the front panel control or CV.

In addition, any or all of the filter channels can be linked together internally producing a parallel filter bank controlled by a single cut-off control or CV. Check out some of the examples for how amazing this sounds.

The AUX CV input can be switched to allow CV control of the filter response, resonance or pan of each filter channel's dual outputs.

Finally, each filter can be overdriven to accentuate the unique sound of each filter type.

Notes: Oscar DSF is a complex, stereo Voltage Controlled Oscillator, based on the mathematics of Discrete Summation Formulae.

The Discrete Summation Formula used in Oscar DSF produces sounds rich in harmonics (or 'partials') in a similar way to FM.

The mathematics of DSFs is more complex than FM, but the way that you, the user, get the sounds you want is usually simpler. The basic sound is controlled by just two, intuitive knobs (with CVs, of course).

Oscar DSF can sound like a traditional oscillator, and it can make the usual clangs and tings associated with FM oscillators. It can handle fat bass sounds, or evolving ambient drones.

Oscar DSF has two complete DSF based, complex oscillators, controlled by the same basic pitch CV, but with a pitch offset control which can detune one oscillator up to i1 octave.

The output of the each oscillator passes through another complex FM stage, which acts like a wave folder. Technically, it's actually an FM operator with the carrier frequency set to zero. It sounds great, whatever you call it.

The final piece of the signal chain is a simple VCA, allowing Oscar DSF to be used as a stand alone synth voice with the addition of an envelope generator, or some other source of modulation.

Notes: Alpha Duo is a stereo precision VCA with ring modulation, overdrive and distortion.

Alpha Duo's VCAs have three modes:

1) Two quadrant, for classic VCA behaviour
2) Four quadrant, where the VCA responds to both positive and negative Gain CVs. This creates a classic ring modulator.
3) In four quadrant separate (4S) mode, each of the two VCA channels is controlled by separate gain CVs, turning Alpha Duo into two independent VCA/ring modulators.

Alpha Duo also features three drive modes.

1) In Drive Mode zero the overdrive circuit is not active, giving a clean signal.
2) Drive Mode One is a tube style soft overdrive. Like a tube, the positive and negative parts of the waveform are distorted differently, producing a pleasing, warm fuzz.
3) Drive Mode Two is a harder clip - more like a transistor amplifier - for a harder edged distortion.

Alpha Duo's signal path is DC coupled, so it's great for processing CVs as well as audio.

Notes: The Pocket Garden Listener is a portable random control messages generator from biometric signals and it's meant to be the compact and desktop version of our Garden Listener eurorack module.

It detects conductivity variations on living beings' surface and transforms them into MIDI notes, ranging from C-1 to C8, and CV signals (0 - 5V).

Its behaviour can be tamed through the one-knob menu from which you can choose and modify:
probes' sensitivity (making it more or less sensitive to current variations)
scale (chromatic, major, minor, Indian and Arabic)
MIDI channel (1 - 16)
LEDs' brightness
USB powered

MIDI data are simultaneously transferred:
via USB, to control DAW plugins and sequences
via TRS, to control any other gear with a MIDI port

Equipped with Trigger, Gate and Control Voltage to control modular and semi-modular gear.

Conductivity variations are detected by the Probes Input and converted into MIDI notes in real time according to the Main menu settings. Each MIDI note exits through the MIDI output and the USB, allowing you to take advantage of the sound of either any synthesizer equipped with a MIDI port or any VST in your DAW, and gets converted into an analogue signal.

Trigger and Gate are fired every time a new note is generated (5V).

All the MIDI notes are converted into variable voltages (0 - 5V) depending on their pitch and exit through the CV output (1V/oct).

The Pocket Garden Listener comes with:
3.5mm white probes
1 set of snap-on adhesive reusable electrode pads
A MIDI-TRS type A adapter for the MIDI output (1m long)
A USB cable (micro type B to type A)
A small Torx-7 key for further calibration
The Pocket Garden Listener comes already calibrated for a proper 1V/oct output.

Notes: The name, indeed, comes from ancient Greek mythology since Proteo was a shapeshifter who could assume whatever shapes he preferred. In this way, our Proteo, has not a precise sound on its own but a clever mechanism that permits to acquire and transform every signal into waveforms. What if you can use your envelopes, LFOs or any other signal as a sound source?

What sets it apart from other oscillators? What's very different in Proteo is its internal pseudo-tape recorder, which is capable of continuously acquiring and transforming any external signal into waveforms and morphing them from a basic sine.

In Proteo, waveforms are not a static digital representation of a sound; they can continuously evolve in a very organic way, and tape loop time is a fundamental factor: changing it will drastically affect the resulting output even with the same sources at the inputs. Slowing down the time will capture a bigger portion of the incoming source with more harmonics. As a result, increasing it allows to capture up to low audio rate signals or really small fragments of the signal.

Exploring the interaction between Proteo, the sources and the time will force you to change your mind about how sounds and harmonics can be generated: visualizing how different shapes can sound and looking for new sources to generate YOUR waveform is the fundamental idea behind Proteo.

Proteo is also stereo, thanks to the Span knob you can easily detune one oscillator from the other to create nice stereo effects. Beside the common pitch the two oscillators have independent acquisition paths and morph controls, each one can emit different waveform.
