Truly Random MIDI Control




Generating random data is incredibly hard, and most of the random data around you isn’t truly random, but merely pseudo-random. For really random data, you’ll have to look at something like radioactive decay or *holds up spork* something like this. YouTube commenters will also suffice. The idea of using random data for generating musical notes is nothing new, but [Danny]’s experimental MIDI controller is something else. It’s a MIDI controller with the control removed, generating random musical notes based on radioactive decay.

Truly Random MIDI Control




The design of this controller is based on an off-the-shelf Geiger counter kit attached to an Arduino. The Arduino code simply counts up in a loop, and when the Geiger tube is triggered, an interrupt sets off a bit of code to generate a MIDI note. That’s simple enough, but where this project excels is its documentation. There’s a zine going through all the functions of this MIDI controller. There are single note or sequencer functions, a definable root note and scale type, an octave range, and velocity of the note can be set.

This is just a MIDI controller and doesn’t generate any noise on its own, but the video of the device in action shows off the range. [Danny] is getting everything from driving bass lines to strange ambient music out of this thing with the help of some synths and samplers. All the code and necessary files are available on the GitHub, with the video available below.
