How to create a MaKey MaKey piano using Max MSP

Max MSP is a visual programming language with nearly endless possibilities for art, music, and pretty much anything you put your mind to.

Wanting to expand our MaKey MaKey piano beyond the standard 6 keys, we wanted to use Max to create a larger piano with more notes. The follow Max patch can be used to create an 11-key MaKey MaKey piano, but could easily be used to create piano with considerably more notes.
