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: 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 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.

Notes: Thererec is a 6hp smart dual-function generator based on a different approach! Two modern proximity sensors have replaced all the Attack/Decay thing, and this not only saved a lot of space but also turned Thererec into a whole new thing: a fusion between THEREmin gestural expressiveness and a tape RECorder,

Thererec, indeed, can quickly capture your hand movements and translate them into complex Envelopes and LFOs, adding a lot of expressiveness to your set. Once recorded, your movements can be mangled in both time and amplitude; they can be cycled or triggered in one-shot mode, letting you create complex but synchronized control voltage streams.

A straightforward movement with immediate feedback: move your fingers, listen, and connect yourself to the environment. Your body will do the rest.

Thererec sensors will track your movements to generate a voltage flow, and the LEDs and the CV outputs will reflect those movements.

Notes: Toolbox is the newest essential utility module for your modular system. It's designed to summarize and replace all those necessary small one-function modules, often overlooked due to their space and cost requirements. With a compact 12hp design, it offers a comprehensive selection of carefully curated blocks to expand and enhance the potential of every patch. The module is also specifically designed for internal interaction, allowing the combination of various basic blocks to achieve compelling outcomes, from complex rhythm creation to unusual sound shaper. Every system needs a Toolbox!

Since VCAs are always not enough, the first two blocks on the top row consist of two linear and very fast VCAs, which are also great for AM modulation. They are arranged from left to right: input (DC coupled), control voltage input (ranging from 0 to 8V), and output. The two inputs and control voltages are normalized from left to right, facilitating easy stereo operation. These VCAs, designed primarily for voltage attenuation, are versatile tools that excel in scenarios requiring linear response. With audio, their true strengths shine when applied to amplitude modulation (AM) scenarios, where the benefits of linear control become quite significant. Although they are optimized for AM and voltage control, using exponential envelopes with these VCAs can transform them into two highly effective and fast VCAs for audio applications.

The threshold CV (0-8V) is crucial for the functionality of the blocks labeled with an asterisk (*): AND/OR gates, sequential switches, and flip-flops. By default, the threshold for each block (the voltage that must be reached at every input for the circuit to operate) is set very low, allowing almost any positive signal to be used. By increasing the threshold with an external voltage, you will change the point at which the circuits marked with the * begin to operate. This may seem a little tricky at first, but once you master all the functionality of the Toolbox, the Threshold CV rarely found in other Eurorack modules will open up many more possibilities!

Still composed of two identical parts, the second and third rows contain two blocks of two-channel summing (A & B). This region offers many ways to combine two signals. From left to right, input A, B, SUM out inverted SUM out, and two Boolean operators: AND/OR While any input signal can be used here, the first two outputs are primarily intended for audio sources. In contrast, the Boolean outputs are more suitable for summing gates and logic signals. This setup also allows for the use of both logic and analog signals together; don't hesitate to experiment with Boolean operators using analog or audio signals.For example, connecting two different LFOs to the input of the summing section can create many gate rhythms from the two Boolean outputs by varying the threshold with external voltages.

Summing mixers/Mult Out: This section consists of two 3-input summing mixers connected in series: the output of the upper mixer is routed to the first input of the lower mixer, allowing you to combine a total of five signals with two outputs available. To break this connection, insert a patch cable into the first input of the lower mixer. This action separates the two sections, enabling you to sum two sets of three signals each. Additionally, the lower section includes a multed output by default.

A bidirectional sequential switch is located at the center of the module and labeled with three "I/O" tags. This often overlooked component allows for a wide range of functions, from the most practical to the most creative. When a voltage exceeding the threshold level is applied to the * input, the switch connects the upper left jack to the lower right one. If the voltage is below the threshold, the lower left jack is connected instead. Being bidirectional, each I/O can function as both an input and an output, enabling a 2:1 or 1:2 configuration. Try using the switch at audio rate; this can function as a versatile oscillator waveform shaper. Think of something other than this block as a simple channel switcher!

On the right side of the sequential switch, we have a more classic block: the flip-flop. This block outputs a square wave at half the frequency of any signal applied to the input, whether audio or gate. Two flip-flops are available, which can be used individually or normalized in series. This block is handy for creating sub-octaves of square format from any sound or as a clock divider.

Offset / Attenuverters: Located at the bottom are two offset and attenuverting channels.This section comprises two identical blocks that can easily attenuate, invert, and offset any input signal. Each block features an input jack, one output, and two small knobs. The first knob functions as an attenuverter, allowing you to invert and scale the signal at the same moment. The second knob, the offset, adds a static voltage of +/-0-8V to the resulting output. This functionality is crucial when seeking a more refined control over voltage or a signal. Without any signal at the input, you can use the offset knob as a manual control generator for any control voltage (CV) in your system. For example, try to change the threshold with it.
