Permutation is a set of random sequencers that use a digital shift register to generate unpredictable CV and gate patterns that can be locked into repeating loops. The concept is based on the Turing Machine, an open source module designed by Tom Whitwell. Permutation retains the core functionality of the Turing Machine while adding new features such as 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. 18HP model features 16 gate outputs, clock output, pause/clock switches, clear/write CV inputs. Includes original box and ribbon cable.
