New notes for noteblocks

Hello,

I've been working on a sound with noteblocks and the problem is that the noteblock allows us to only use 2 octaves. I was wondering if it was possible to add few octaves higher and lower (like 1 or 2 of each) just to have more fun playing with them, doing some cool musics or doorbells etc... 

I hope that the feature will be added on the next versions.
