Loop Machine - Play Melodies - 1.9+

Hi,
with this contraption you can play your own loops!
To do that simply build blocks for the notes you want to play, flick the lever and it will play it in a loop!
The following blocks can be used: Glowstone, Gold Block, Diamond Block.
You can also save and load your loops.
If you want the machine to look different you can change the ground theme by simply clicking on a sign!

Every Loop has 16 blocks length which is 4x4 16th or 4 beats. One block is 4 ticks (0.2 sec) long so the beat is at 72 BPM.
You can play a major scale from F#3 to F#5 over two octaves with piano sound.

I already put some examples in that you can load.

If you accidentally break one of the signs you can take it from the chest between the command blocks. But you have to place the sign at the exact same position as before! Else you could break the whole machine.

This contraption is inspired by SethBlings Mob Music Maker which is inspired by this website ;D
I got the idea from SethBling's video but I built everything by myself.

Sorry for my crappy English, i'm German xD

The resourcepack I am using is Sphax PureBDcraft 64x 1.10R1 + 3D Blocks and Technology Add-on.

If you have any suggestions, questions, wishes, opinions or even found a bug fell free to leave a comment!

Hope you enjoy it!
If so, please leave a diamond, thx!
