ABSTRACT
Th e musical applications of digital logic circuits go well beyond simple oscillators. Once you accept that an audio square wave can be regarded as a simple alternation between two binary numbers (0 and 1), the logical and arithmetic functions on which all digital calculations are based can be seen as potential sound transformations. For example, a chip that performs division, such as the CD4040 12-Stage Binary Divider, can be used to generate several harmonically related pitches from a single master oscillator (see fi gure 21.1).
