In this chapter we covered a lot. We created our first Pd patch and discussed objects and how to create them. We saw the difference between scalar values and signals, and used a signal to make our first sounds with Pd. Then we covered a few ways of controlling a signal’s volume and talked about messages and how they could work together with an oscillator to play musical notes.
Next we’ll build some useful tools that will help us visualize the sound we’re generating and control how sound happens over time. These tools will be integral to patches we build in the chapters after that.
