# Stick-on Twelve Button USB MIDI Controller

![Twelve button USB MIDI controller](./images/buttons12.jpg)

Sometimes your gear really needs some MIDI control buttons strategically

located. Now you can stick them on where needed.

## Hardware

* SparkFun Pro Micro or Arduino Micro

These boards are convenient because the pin arrangment includes a section with

seven digital pins in a row. The cable from the keypad can be plugged directly into

that section of the board. Other boards with the ATMEGA32U4 chip should work

but might require extra work to wire the keypad to the board.

The photo shows a Pro Micro clone board. Right angle headers are used to keep

the assembly as flat as possible. After soldering, the pins on the back were

cut flush with the board.

* Generic 12 button membrane keypad

Stick on where needed. But it may not be easy to remove so think twice before

sticking. Peel off the white paper on the back to uncover the adhesive. The

Arduino board can be stuck on using double-sided foam tape. This stuff is also

hard to remove.

## Software

Install the Keypad, MIDIUSB, and MIDI libraries using the Arduino IDE library

manager.

The sketch can be customized to send MIDI messages.

NOTE: System Exclusve arrays should be stored in program memory using the

PROGMEM attribute then sent using the USBSystemExclusive_P function. If not,

RAM will be quickly used up.
