Description

NOTE: THIS IS A FULLY-ASSEMBLED MODULE (NOT A KIT)

The Grayscale Permutation Eurorack module is a random looping sequencer that uses a linear feedback shift register (LFSR) as the basis for generating unpredictable CV and gate patterns.

It is a direct descendant of the Turing Machine, an open source module designed by Tom Whitwell of Music Thing Modular. The TM itself was inspired by classic random signal generation units such as the Buchla Model 266 (Source of Uncertainty), the Wiard Model 1210 (Noise Ring), and the Triadex Muse (an obscure device invented by artificial intelligence researchers at MIT in the 1970s).

Permutation retains the core functionality of the Turing Machine and its Pulses expander while adding new features in a more compact interface. Variant, a compact 6hp expander module that provides a secondary means of generating correlated random sequences, is based on the original Voltages expander for the Turing Machine.

Permutation comes in 3 different versions – 6hp, 12hp & 18hp – all with different sets of features (see below).

Depending on the version chosen, new features may include: dedicated outputs for each bit of the shift register; CV inputs for all parameters; and an internal bipolar VCA. Locked sequences are also saved across power cycles.

The manual for all versions can be found HERE

Permutation Comparisons

Each version of Permutation has a slightly different set of features. The 6hp version has an assignable CTRL input. Holding the Clear/Write switches down for a few seconds assigns the CV input to Shift, Bits, or Amp (the internal VCA).
