I am very confused about what you are asking.
The code that you attached (should have been inline with code tags) seems compatible with an Arduino Uno R3. What about it is "not compatible"?
What is "Hairless Midi software"?
How do you have your piezos and your midi connected? A schematic or wiring diagram would be nice.
Please provide more information and clarify your request.
