R64 Music are advanced versions of the Note Block. The R64 Music GUI allows you to specify 12 Notes with 12 delays as well as change the note type. With the use of a MCI Location you can set the point where the music will play rather than having it play at the R64 Music's location. When a redstone signal is sent to the left side the R64 Music will play its tune, once its finished it will output a redstone signal on its right side. The top R64 input allows the delay to be dynamically changed and the bottom R64 Input allows the notes to be dynamically changed.
