In this section, we will attempt more imaginative visualizers wherein our visual structures will be animated not according to some signal's waveform or spectral characteristics, but rather with respect to more abstract musical properties such as the frequency of a particular element or the output of some pattern.
In this example, we rotate five windmills with respect to the detected frequencies of five complex sound sources. Each of our five instances of
Synth also writes the frequency information (tracked in real time via
Tartini) to an instance of
Bus to be accessed later by our
drawFunc function and set the rotational speed accordingly. Herein, we rely on the windmill factory we had demonstrated in Chapter ...
