Long story short, it’s a random looping sequencer. For a full description of the Turing Machine and its expanders, go to Music Thing Modular<\/a>. The MkII version was introduced in 2016. I bought a full kit from Thonk<\/a>. The PC board set I received is marked Revision 6, 2018. I skipped this module for a long time, just because of my low interest in sequencers. This has one non-quantized output. It needs an external clock to get going. The big knob lets you set the amount of randomness and at either extreme it locks in a sequence. This is under CV control, too.<\/p>\n\n\n\n

I also built two of the extender modules, Pulses Mk II and the Vactrol Mix. I’ll describe those in a separate post. I would highly recommend getting the Pulses expander plus one or more of the Gate expanders. They add a lot of functionality and it’s nicely integrated.<\/p>\n\n\n\n

Construction<\/h3>\n\n\n\n

The finished module is shown below without the front panel. There are two PC boards that connect together via three pin-and-socket header sets, and held firm by two metal standoffs.<\/p>\n\n\n\n

Back of the IC board, also the back of the module<\/figcaption><\/figure>\n\n\n\n

The only part I changed was to substitute a keyed power header. GATES and PULSES headers are for connecting expanders. The expanders are powered from this board via these headers.<\/p>\n\n\n\n

Notice the blue trim pot. There’s a hole in the front panel for adjusting it.<\/p>\n\n\n\n

That’s the construction of the Turing Machine MkII. Next up: two expanders plus a recording of the ensemble in action.<\/p>\n\n\n\n
