In this guide, I'll show you how I built this strange looking MIDI controller. It doesn't look like your typical drum pad or keyboard, but it does have similar functionality just like any standard MIDI controller. It features six capacitive touch pads that trigger MIDI notes. Tap one of the pads, and it plays a note. It also features a step sequencer so you can record and playback a pattern. The 16 NeoPixel ring displays a glowing dot for each step which also follows the beat of a given tempo. It can also change settings, such as pitch, tempo, shuffle, length, velocity and even MIDI channel.
