Facts: Denotators and Their Visualization and Sonification

The facts, or objects, that the rubette BigBang in RUBATO® Composer deals with are denotators, which can be considered points in the spaces defined by their forms, as introduced in Chapter 6. So far, we have only seen a small portion of the variety of forms that can be defined in RUBATO® Composer. However, any conceivable musical or non-musical object can be expressed with forms and denotators, many of them just with the category of modules Mod@. The most recent version of BigBang was made compatible with as many forms as possible, even ones that the users may spontaneously choose to define at runtime. In order to handle this as smoothly as possible, we had to find a suitable way of representing denotators within the rubette, which we call BigBangObjects.¹ In this chapter, we describe how this works.
