Turing Machine Mk II

Music Thing Modular's random looping sequencer in 10 HP, open source. A shift register makes strings of random voltages that the big knob locks into a loop, lets slip a little at a time or leaves fully random. LENGTH sets the loop from 2 to 16 steps, WRITE changes the bits by hand, SCALE sets the output range; the eight LEDs show the register. OUT gives the voltage, PULSE a pulse and NOISE the noise the bits are drawn from, on each CLOCK. Behind the panel it drives the Pulses and Volts expanders.

Key features

• Loops of 2 to 16 steps, locked, slipping or random
• Voltage, pulse and noise outputs
• Eight LEDs showing the register
• Drives the Pulses and Volts expanders
• Open-source design (CC-BY-SA)
