Programmable Note Block Machine (imporved version available)

A user friendly tool that relieves a lot of the tedium of making music with note blocks. A code is fed to a line of 25 note blocks, making the music stationary and lag resistant, and it makes tuning a cinch! To program a note, replace a piece of glass with a solid block and redstone dust in the appropriate place. White glass represents the start of a bar, black glass is an 1/8th bar, dark grey glass is a quarter bar and light grey glass is half bar 4/4 timing. Other timings are possible. Use the piano as a visual reference for pitch. Right click the note block in the center to play.
