Piano Patcher

There is a theory on piano that, if you only play the black key, it will always sound beautiful, for it align with the traditional Chinese music theory “宫商角徵羽”. So what ever you play, it will sound like a pretty traditional Chinese music. In this case, I first align all the computer key into one black key on the midiboard, wich makes the player can play whatever they like. I then create a random function, to let the keyboard play the music on its own, which can also provide beautiful music and sounds interesting. Last but not least, I create the function that the players can both random an instrument or choose one, so that the midiboard is under the control, but can also provide random fun.
