Monome: Open source extremely simple device


Monome is an open source USB device that can be reconfigured to trigger the actions you may need.

People at monome have developed a 64 buttons device (in a 8 x 8 grid) that can be used for any purpose. They suggest DIY enthusiasts, crafters, educators, etc. But let’s recall on musicians.

This device can be configured to be used with any audio recording, mixer or synth software. The open source license allows people to use it the way they need and, imagine building your own “my-way-button-distribution” mixer to use with ProTools, Cakewalk Sonar, Logic Audio, etc.
