  • Please post your code to get feedback about your issue. I suggest you get the music loaded and working first before using controlP5 to build your GUI.

    You should also explore the examples that comes with the library if you haven't done so. At the end of each example, you find the documentation related to that example. You can also explore the examples and the library documentation in the library's website:
