“A Different Looking MIDI Controller
In this guide, I’ll show you how I built this strange looking MIDI controller. It doesn’t look like your typical drumpad 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.
BLE MIDI Drum Machine
This project is based off of Todd Treece’s Capacitive Touch Drum Machine. Todd’s project uses an Arduino, MPR121 touch capacitive sensor and a strip of 16 NeoPixel LEDs to make a simple drum machine that you can use to control MIDI devices and virtual instruments. This project is built on top of that sketch and adds BLE connectivity. The future is here!”
