figuring out the x and y coordinates in relation to the notes on the electronic organ

Altering x and y in excel.

The altered print, replicator G shows a live trace of each layer, plotting the z and y coordinates and referencing the z.

INPUT... To change the melody once a makerbot print has been made, the x and y coordinates on each layer need to be altered in the same position (for example (x2.0 Y 4.0) between the z6.0 to z11. The z position changes which organ will play the altered piece.
