[Keith Baxter] loves making electronic instruments. His latest vision has come to life as Kyub, an open-source MIDI keyboard. [Keith] has previously graced our site and cracked Popular Science with his servoelectric guitar.
[Keith] wanted to make a completely open source instrument that’s elegant, useful, and a bit more accessible than the servoelectric guitar, so he teamed up with a hacker/electronic music expert and an industrial designer. He built the early prototypes around an Arduino Uno. The current iteration uses a Teensy 2.0 and is available in various forms through Kickstarter. [Keith] opened the Kyub up to crowd funding in an effort to obtain volume pricing on some of the parts as well as an Eagle license to make the PCB files available commercially.
The Kyub has eleven pressure-sensitive capacitive keypads on five sides of the cube. The accelerometer can be used to vary note volume, bend the pitch, or whatever else you program it to do. Of course, you’ll need a computer with a synthesizer program, but [Keith] says it is compatible with most software synth programs, some of which are free.
There’s a demo video of an early prototype after the break. Videos of the Kyub in its current form are available on the Kickstarter page.
