The Human Comparator has revealed a new box of noise called the Recursive Machine. It’s drone synthesizer and noisemaker DIY project with lots of patching and a natty handle.

It’s small, portable, battery-powered, has a speaker, it’s packed with patching and comes as PCBs and a 3D printable frame. It’s built for drones and making interestingly long-form weird noises.

In the box you get two oscillators, state variable filter, distortion, reverb, two delays and two LFOs. You also get a small mixer and a pair of VCAs. It’s all normalled behind the scenes in the ways you’d expect a synth to be patched so you can simply get on with messing about without having to plug in any cables.

Sound builds very quickly once you start to play. Anything that runs through two delays, a distortion and a spring reverb is going to find itself interesting before too long. It’s quite fascinating to watch in the video (below) as things evolve without much input from the user. You can then start patching and break into the normalled way of doing things to find your own paths.


It looks like an interesting DIY project. The layout is very ordered and straight-forward so although it’s a bit packed in there you certainly won’t get lost. But it’s the sort of thing you could lose yourself in for hours of joyful droning.

You can buy the PCBs and frame from THC for about £85. The parts will probably cost around £200.
