This phenomenon is accomplished by monitoring your mouse movement and buttons plus both horizontal and vertical scroll wheels. This state information is then fed into a modular synthesis environment capable of producing many types of audio, including buzzes, swooshes, bumps, chirps, melodic notes, various modulating tones, all sorts of noises, and countless other audibles just waiting for your ears. Unlike desktop themes and related downloads, RolloSONIC does not merely *play* sound files -- it *creates* the sounds you here from scratch. Furthermore, there are a great many aspects of the sound generation that can be modified and controlled by you while you are listening to it, which enables you to customise the experience and atmosphere. RolloSONIC brings out the expressiveness your mouse has been yearning for all these years.
