A note block that functions as a player piano or 'pianola'

With the coming of The Sift and its musical aspects, it would be cool to add a music box/player piano type note block.

The 'pianola,' or another name, can play a series of programable notes that can be given block to change instruments.

Crafted like a jukebox it should include: any planks on the top two slots on both sides, a copper grate in the top middle slot, a diamond in the center middle slot and smooth stone in the bottom three slots.

They can be interacted with to add or remove a metal cylinder that holds the notes. this should be crafted with either copper, iron, or gold with an ingot with a nugget on its right and its left.

These cylinders should be able to interact with a music sheet to either add or remove the music. These sheets should be crafted with a piece of paper, a feather, and an ink sac.

These music sheets would have a GUI that allows players to find the right notes, put in rests, and accept blocks to change the instrument under each note.

While the pianola might have a note limit, and it should be a decent amount, it should output a redstone signal when finished playing so that it will trigger a new pianola.

I believe that these would open up music making by condensing large scale note block music machines to only a few blocks and would help servers and maybe map creators.
