Hi All,
I'm taking an Audio Electronics course which involves an Arduino UNO. The problem is, the code for this project I'm building was made 5 years ago, and I have no idea how to fix the code to work for Arduino today. The project is a DIY MIDI controller called the SugarCube Synth (https://www.instructables.com/id/Sugarcube-MIDI-Controller/).
After completely copying all of the code that the original builder coded for the project, I still keep getting an error message of:
/var/folders/ly/t44swsyn56ldvv0_12hnp76h0000gn/T//cc44r57c.ltrans0.ltrans.o: In function main': /Applications/Arduino.app/Contents/Java/hardware/arduino/avr/cores/arduino/main.cpp:43: undefined reference to setup'
/Applications/Arduino.app/Contents/Java/hardware/arduino/avr/cores/arduino/main.cpp:46: undefined reference to `loop'
collect2: error: ld returned 1 exit status
exit status 1
Error compiling for board Arduino/Genuino Uno.
Below is the code I'm trying to upload:

I've included all of the extra .h files I needed.
If anyone has time to look at this, I'd really appreciate the help. My project is due next week, and I'm beginning to panic. I've been trying to figure out how to fix this myself, but I have no idea how to even begin to read any computer code, let alone Arduino code.
Thanks so much in advance._
