Turing Machine MkII by Music Thing Modular is a binary sequencer, based around a 16-bit memory circuit called a shift register. It’s designed as a sequencer that you can steer in one direction or another, not one that you can program precisely.

You cannot program this sequencer to play specific tunes. You cannot save sequences. You can never go back to a sequence that has changed.
To put it another way: This random looping sequencer is a module that produces clocked randomly changing control voltages. Unlike many random voltage generators, these sequences can be locked into loops that repeat according to the length control.
Specifications:
