integrating CHAI3D example in C++ with a dataset

I have implemented an example of CHAI3D and it's displaying 4 items that plays a sound when you click and hold on them using the mouse cursor. I want to update this project so that it's displaying 12 items that have the same functionality of the 4 items (playing sounds when you press on them), additionally I want to add a square that changes color based on the dataset used. The project is written in C++ and below is the link for CHAI3D documentation:
