How to Add Midi Port to a Keyboard

Turn any cheap keyboard into a MIDI keyboard!

This is a tutorial for adding a MIDI port to a keyboard without one, so that you can use to interface with various programs such as FL Studio, Ableton Live, Cubase, Garage Band, Pro Tools, and more.

Also works with Synthesia!


Materials used:
1 Arduino Uno
2 Serial-parallel register
6 10k ohm resistors
1 220 ohm resistor
1 Prototype board
1 Female midi port
1 Male pin header

All can be had on eBay for approximately $10 USD.


Final Arduino code:
