Converting my 61 key keyboard to MIDI ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Keys that are next to each other are still not detected together. That's a problem for another day. I'll solve it when I need to press neighbouring keys.

To play the keyboard with MIDI without updating firmware

1. hairless MIDI
2. loopMIDI

MIDI baudrate is 31250.

"NB: To convey Windows MIDI data from one bit of software to another, you’ll need a Virtual MIDI passthrough driver. We recommend loopMIDI, or there is alternatively the older MIDI Yoke (MIDI Yoke is not recomended for Vista or newer.)"

TO REPROGRAM ARDUINO'S ATMEGA CHIP

This is to update the program.

1. http://morecatlab.akiba.coocan.jp/lab/index.php/aruino/midi-firmware-for-arduino-uno-moco/?lang=en Before connecting Uno to PC, install a jumper between pin4 and pin6 on ICSP connector (this is the USB connector ICSP not the Mega ICSP) for Mega8u2/16U2. With the jumper, Arduino-serial mode is initiated. You can use Arduino IDE to program mega328 on Uno.

There's a picture on the website. Look at it for help.
