I need a creative coding for a processing project

We would want to create a audio particle effect system in processing with Java. The requirements are the following :
1. There will be 4 audios and also 4 different particle effect assigned to each corner of the canvas. Please leave the spaces for us to put the audio files.
2. We would want to audios and the effects to be controlled by mouse movement, where the mouse position affects the percentages of the audios and effects to happen. e.g The mouse is positioned around the left top corner, the audio and the effect assigned there will be more likely to be played and showed.
3. Please make it interesting and interactive.
4.Please use the processing sound library or maybe you can you the Minim library
5.Please also make classes that can be used in the code
