The Minecraft Note Block Studio (Previously known as the Minecraft Song Planner) is a music editor for Minecraft. With it, you can compose complex note block songs, requiring no redstone knowledge whatsoever. Unless you are planning on importing your song into Minecraft, the range of the note blocks can go far beyond the 2 octaves in Minecraft, and the program also give users the ability to add their own instruments and assign custom sounds to them.

The Program also Allows you to Import and Export as a MIDI ( Musical Instrument Digital Interface ) as well as a MCEdit Schematic File, Making possible to change any song online written in Midi to be easily put into Noteblocks.
