Replacing key input with midi input

Hello!

Im fairly new to writing code and using unity. I know a small amount about writing in java and C# and one area I am very interested in is the ability to control game objects with midi information. My goal right now is simple. I want to write a script that allows me to control the main characters ability to travel on the horizontal axis with a NoteOn Message from my midi controller instead of the key input from the WASD keys. Does anyone know anything about this ? Thanks !

All the best Alex
