An Audio Synthesis Textbook For Musicians, Digital Artists and Programmers by Mike Krzyzaniak

7 Sequences

Explanation of the Concepts

The previous chapters have all dealt with various methods of making time-continuous signals. Often, however, it is necessary to produce a signal that holds its value for some length of time before changing values. If one wishes to make a melody, for instance, each frequency will have to be held for a time, and then switch all at once. This chapter explores some of the ways that analog synthesizers achieve this.
