Mystic Circuits Introduces Leaves Turing Machine Expander Module

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.
