You could take the skills you’ve developed in this book in a few directions. I’m sure you’d like to dive in and build that music app taking shape in your mind, or replace some static samples with dynamic sounds in the game you’ve been working on with friends. By all means, build something awesome with Pd! Here are a few other suggested steps to take next to build your skills as a sound designer.
It never hurts to practice. Designing sounds just to explore how you might solve a particular case is a great way to enhance your skills. Try to model a bird chirping, the sound of wind in the trees, a gunshot, a car engine, or an ambient musical soundscape that reacts in different ways to input.
