OVERVIEW
========
This is a hacked version of Tim Gipson's awesome mid2cnc code to support the MakerBot Cupcake CNC 3D printer. The gcode file will voice the song in the Z axis only.
mid2cnc requies a MIDI file, and I've found that this workflow is effective on OS X 10.5.8, YMMV:

1. Obtain the song you want as a PowerTab guitar tablature file. Search for .ptb or gp4 files using your favorite search engine
2. Use Tablatures or other application to convert tablature file to MIDI file
3. Use mid2cnc to convert MIDI file to gcode file.

INSTRUCTIONS
============
Usage:
python ./mid2cnc.py midifile gcodefile ppi
Example:
python ./mid2cnc.py ../man_on_the_silver_mountain/man_on_the_silver_mountain.mid ../man_on_the_silver_mountain/man_on_the_silver_mountain.gcode 800

You may have to experiment with the ppi value to get the song right; 600 is a good place to start. Larger numbers make the pitch lower and the song slower.
