Arduino Programming

We have just been notified by our advisors that each instrument in the symphony will not be controlled by its own program, as we had previously been led to believe, but that they will all be controlled by a single midi program running on a single computer. The main program will ensure all instruments keep tempo and play the correct notes at the correct time. However, this means that all the code and calculations previously done will not be used in the final performance. Instead we will need to edit the code written by our advisors to fit our instrument. Because the code was written for a xylophone type instrument, the code will have to be changed significantly to accommodate the recorder, as the example code was for a xylophone.
