convert the Yamaha YK-10 to a MIDI Keyboard

🌊YKiss

convert the Yamaha YK-10/20/01 🎹 to a MIDI Keyboard by only using an arduino uno

Yamaha YK-10 (YK-01/20) Keyboard is an optional part for the Yamaha CX5M Music Computer which is a great meachine with FM model build in.but the keyboard only has a 20PIN interface,therefor we can use YKiss to add MIDI interface and make the nice keyboard GREAT AGAIN !

✏️Material

No	Description
1	Arduino UNO R3*
2	Wire jumper
3	Resistor 20KΩ
4	Breadboard

• please don't use the chinese cheaper editon of arduino UNO, for the Mega16U2 was replaced by the CH340 usb to serial chip.

🍤GUIDE

STEP 1 : burn the MIDI firmware for Arduino Uno

we use the great project mocoLUFA to make Arduino UNO behaved as a USB MIDI Device,first you should follow the guide in morecat_lab ,Installing the dualMocoLUFA firmware to Mega8u2/16U2 If you have questions about the mocoLUFA documentation, you can also follow the steps below：

1-1. download the dualMocoLUFA firmware: Mega16U2

1-2. Updating the Atmega16U2 on an Uno using DFU

please see the offical doc for how to use DFU to burn firmware

STEP 2 : using the Arduino IDE to update program

just burning the YKiss.ino to Arduino Uno,before connecting Uno to PC, don't forget to install a jumper between pin4 and pin6 on ICSP connector for Mega8u2/16U2 when you buring the program.

STEP 3 : connect the 20PIN to Arduino

from the yamahayk01sm document we can get the detail of YK-10's 20PIN interface.just you see,the keyboard don't have any chips,but a pure matrix keyboard,so it makes things easier！

20PIN	UNO
11 to 16	A0 to A5
2 to 10	2 to 10

• please connect 20K Pull-down resistor to all used PIN

STEP 4 : enjoy the YK-10 with Ykiss just as a normal midi keyboard !

don't need MIDI cable*,just useing the USB to connet to your PC,of course you should uninstall the jumper between pin4 and pin6 first !

• if you want to use MIDI OUTPUT cable to connect other MIDI Drvice,you can make it yourself by using the TX pin
