The unique part of the circuit is a voltage controlled A/B switch thats normalled to the “Rand Gate” out that’s switching between the S/T\H out (left Blue led window)and Infra out (right Red led window), the Glide control also effects the S/T\H coming out of the switch so you can get really random results from the “Entropy Out.” Inserting a cable into “Switch CV In” breaks the random gate normalization and lets you toggle between A/B (left S/T\H out and right Infra out, indicated by the led windows) with your own gate or trigger.

The “Emanate” potentiometer controls the coarser overall spectrum of the chaos, from lots of activity counter clock wise up to less chaos and more of a steady oscillation full clockwise. The “Width, CV ATT” potentiometer can be thought of as a fine control for the chaos/oscillator. When something is inserted into the “CV” in the voltage normalization from the width knob is broken and the potentiometer now acts as an attenuator for the incoming cv. The Triple Cap is not a traditional volt per octave exponential VCO, and has a sort of narrow frequency range to exploit the chaotic behavior.

It expects a +5v to -5v max signal in to modulate the chaos. The “IN” jack is an A.C. coupled input for audio in, although cv and audio can work for both the “CV” in jack and “IN.” The “IN” will interfere and interact with the onboard chaotic oscillator depending on the frequency of the input, which may take some experimentation. It can create ring mod ish sounds, to added harmonics, to almost bit crushed sounds depending on the “X” or “Y” output. The “X” output is a more windy noisy sinusoidal based output and the “Y” output is more squared off and aggressive, harsher sounding output.

Diode Chaos produces 3 phases of interrelated morphing voltages including a chaotic trigger out. The range is around 30 seconds a cycle up to audio rate. The frequency is controlled by the RATE knob. Each output exhibits different behavior at different rate settings. X, Y, and Z outs like to stay in the 4Vpp range although at different RATE settings the outs can reach 10Vpp. The TRIG out chaotically releases 0-10v triggers although sometimes it will spit out smaller voltage peaks.

LED soldermask windows provide constant display of positive and negative voltage crossings.

The concept is simple. It contains two identical smooth random voltage generators. Each has a frequency, level, offset and curve control. The frequency control sets a steady pace with which bipolar random voltages are generated. The level control works like an attenuator/VCA on the output, reaching from max output to closed. The offset allows shifting the whole wave up and down on the voltage range. Curve determines the shape of the interpolation.The bipolar activity on the main outputs as well as gate outputs are visualised with LEDs.

Both Frequency and Level controls have a CV input with attenuator. When there is nothing patched into the CV inputs, these are internally connected to the main output of the other channel. This normalization makes it very easy to add randomization to the frequency or level for more depth, or of course, add cross-modulation for chaotic voltages.

The output VCAs are usefull to dial in subtle and time-based modulation without the need for external VCAs. For example, to modulate the amount over time with an envelope, or use the other generator with slower speeds to add random changes to the level of a random voltage.

Both generators also have two other outputs. One is an exact inversion of the main output, so it responds to the level and CV input. This is great for stereo or inversed effect patches. The other is a simple pulse output, here there are two different behaviours, channel A outputs a pulse at every random generation, channel B acts like a comparator. Whenever the main is positive this comparator output is a high gate. And whenever the main output is negative or close to 0, there is no gate output. Great for random triggers or firing other events like envelopes.

A couple other outputs are also available and are obtained by averaging both channel main outputs. The first output is the average while the second is an inverted average.

Mutable Instruments Marbles is a random module for modular synthesizers in Eurorack format. The module offers many different ways to impress a structure on the random events created by the module: Synchronization with external clock signals, control of repetition or renewal of the generated material, quantization of voltages or randomization of gates or voltages generated by sequencers. Two parameters are available: t, a random gate generator and x, a random CV generator. As a special feature, Marbles remembers every new beat deviation of the rhythm or the tension it has generated. The Deja Vu button on the control panel controls the likelihood of reusing past material instead of collecting fresh random data.

Finally imagine the buoys would wirelessly transmit their absolute height directly to your module outputs where they would be mapped to a voltage signal.

We use a Gerstner Wave as the motor behind the two-dimensional wave generation. In fluid dynamics a Gerstner Wave is described as “a progressive wave of permanent form on the surface of an incompressible fluid of infinite depth”. Gerstner waves are often used in computer graphics to simulate any type of water surface, if you’ve seen any animation film or computer game with water surfaces in it most probably it features a Gerstner wave generating it.

The post Steady State Fate Ultra Random Redux Eurorack Module appeared first on Elevator Sound.

Sliders allow you to set the internal clock tempo (RATE), shape the probability of triggering (PROB), blend old with new values (RND) and set the shape of all four random outputs (SHAPE).

4 different controls

– RATE
Adjusts the internal clock’s tempo. Upon each clock trigger, the RATE slider light blinks, and there is a chance for the internal random source to generate a new value.

– PROB
Sets the probability of generating a new random value each clock cycle. If one is generated, the PROB slider light blinks and a pulse is emitted from the TRIG output.

– RND
Blends the previous value with a random one, in a proportion determined by the RND slider. It affects the range of the voltage output.

– SHAPE
Controls the transition shape to the new random value across all four outputs.

Internal random & clock source
Whenever the clock activates, the RATE slider’s light flashes. At the same time, there’s a chance that the internal random source will create a new value, depending on the PROB slider’s setting.
If it does create a new value, the PROB slider’s light flashes too, and a pulse comes out of the TRIG output.

External IN & TRIG inputs
If the TRIG input is patched, the RATE slider is ignored, and the internal clock is only triggered when an external trigger is received. The PROB slider is used to filter this trigger by applying some probability.
If the IN input is patched, this external voltage is used instead of a random voltage upon each trigger. The RND slider has no effect.

SHAPE Outputs
The STEP output changes in fixed steps. With the SHAPE slider at 0%, it moves to the new value in one quick step. At 100% SHAPE, it takes 16 even steps to reach the new value from one clock trigger to the next.

The LIN output changes in a straight line, its steepness controlled by the SHAPE slider. At 0% SHAPE, it instantly jumps to the new value. At 100% SHAPE, it gradually moves to the new value throughout the entire clock cycle. For values in between, it reaches the new value faster and then stays there until the clock cycle ends.

The SMTH output smoothly transitions between values, mimicking the curve of a sine wave. The SHAPE slider adjusts how quickly this happens. Once it reaches the new value, it stays there until the end of the clock cycle.

The EXP output changes values exponentially. The rate of this change depends on the SHAPE slider. At 100% SHAPE, the change is linear, meaning it straightens out.

Self-modulation
Thanks to a switch in the back of the module, you can normalize the LIN output to the 4 CV inputs and adjust the amount of modulation for each parameter with the attenuverters.
This adds another layer of randomness to your results, enabling more dynamic and unpredictable outcomes.

The post NANO Modules VCV Random Eurorack CV Generator Module appeared first on Elevator Sound.

Each channel also features a recordable trigger generator with an algorithmic fill feature to get the inspiration started or to make things polymetric and keep your patches ever-changing. Use the SHIFT button to change modulation shapes and sync selected or all channels to an internal or external clock.

Neo Trinity has been designed with performance in mind, so it includes channel mutes and allows storing whole presets as banks.

While the core mechanics of the module are very straightforward, the inclusion of assignable CV inputs exponentially increases the complexity of the module’s behavior. Control some or all channels in different ways with the META IN and utilize channels’ E and F dedicated inputs. The inputs can control the main parameter in a positive or inverted way, control the output amplitude, and act as an external trigger or a trigger for the internal Sample & Hold function. The CV knob recorder mode also acts as a quantizer, and when combined with the CV inputs, it turns into a handy voltage processor.
