New Eurorack Module, IDUM, Lowers The Barrier To Making Intelligent Dance Music

[embedded content]

Mystic Circuits has introduced IDUM, a gate processing effect for Eurorack systems that promise to make creating IDM (intelligent dance music) easy.

Making complex electronic music with a modular can require a large system and a level of expertise beyond the reach of many modular users. Mystic Circuit says that IDUM puts making IDM “into the hands of people with average intelligence.”

And, if you do happen to be a brainiac, IDUM is based on open source code and Arduino-based hardware, so you can go wild bending the module to your will.

IDUM acts like an effects processor for the sequences that run through it. The module manipulates the gates and sequences of connected modules, but with a level of playability normally inaccessible to a sequencer. IDUM can vary carefully crafted sequences or turn your music into an onslaught of controlled chaos.

IDUM has eight effect modes:

  • HOLD – Alter the length of incoming triggers.
  • BURST – Generates a ratcheting effect with timing determined by the clock.
  • MULTIPLY/DIVIDE – Generates a ratcheting effect with timing determined by incoming triggers.
  • BALL – Generates a bouncing ball effect.
  • ROTATE – scrambles the connections of inputs and outputs.
  • DELAY – postpones incoming gates by a dynamic amount of time based on incoming triggers.
  • BREAK – preset rhythms that turn incoming triggers into breakbeats.
  • SKIP – manipulates the clock output to multiply the clock speed or skip forward multiple steps.

In addition to these modes, IDUM features an eight step looper that loops incoming gates as well as any effects that were active on those steps.

To control when IDUM’s effects are active, the CHANCE slider sets the likelihood that on a given step an effect will activate and the LENGTH slider sets how many steps the effect will last for. The PARAM knob controls a parameter unique to each effect while the MODE knob selects the mode. All of these controls as well as the LOOP status have their own CV modulation inputs.

Unique to IDUM is its ability to manipulate external sequencers using the clock output. This includes functions like: pausing the clock when an effect is active for dynamic clock division, skipping forwards or multiplying the speed of the clock in SKIP mode, and looping a sub-section of sequencer steps in the looper. To keep everything tamed while manipulating the clock, the CYCLE switch will send out bursts of clocks to catch your sequencer up with its original sequencer position after an effect has completed.

Here’s an in-depth guide to IDUM:

Mystic Circuits Introduces Leaves Turing Machine Expander Module

[embedded content]

Mystic Circuits has introduced Leaves, a new Eurorack module that’s a voltage sequencing expander for their sequential switching module Tree. 

It’s based on the open source Turing Machine expansion protocol, which means that it works with any other modules that host Turing Machine Expanders, including Turing Machine, Vert, Grayscale Permutation and others.

Leaves is designed to support many complex sequencing possibilities, with multiple inputs and outputs and the capability to daisy chain many expanders to a single host.

Designed with non-linear sequencing in mind, Leaves is the beginning of a set of expanders intended to grow Tree from a unique sequential switch into the center of a flexible modular sequencing environment.

Each of Leaves four outputs correspond to a different range of sliders, and each of those outputs has its own dedicated transpose input. All outputs can have a 0 – 5V range but, by default, the final output (which reacts to all eight sliders) has a 0 – 2V range, which makes it more useful for note sequencing. This also makes the slider’s center detent indicate one octave of range, whereas setting the slider fully up gives two octaves of range.

The sliders feature an eight-color LED rainbow that corresponds to the colors on the host Tree, making it easy to identify which steps are active across an entire range of expanders.

?Leaves is fully open source and all relevant files are hosted on the Mystic Circuits Github page. Much attention was paid to the expander port itself, each expander port is buffered at the input to avoid issues when many modules are chained together. The expander ports are duplicated to allow for easy daisy chaining of many modules to be hosted by a single expander.

Pricing and Availability

Leaves and Tree are available now via the Mystic Circuits site, priced at $250 and $180 USD. Escape From Noise in Sweden is also expected to have both Leaves and Tree in stock soon.
