Code Your Own Synth Plug-Ins With C++ and JUCE

This is the source code that accompanies the book Code Your Own Synth Plug-Ins With C++ and JUCE by Matthijs Hollemans, available for purchase from Leanpub as PDF and ePub.

This 360-page book teaches step-by-step how to design and build a software synthesizer plug-in that can be used in all the popular DAWs such as Logic Pro, Ableton Live, REAPER, FL Studio, Cubase, Bitwig Studio, and others. The plug-in is made using industry standard tools for audio programming: the JUCE framework and the C++ programming language. You'll learn all the fundamentals of writing audio plug-ins in general and synths in particular, in an easy-to-follow guide that is light on math and heavy on being practical.

If you don't have the book yet, you can download free sample chapters from leanpub.com/synth-plugin to see if you like it.

How to use this repo

For each chapter there is a folder with the finished source code. Open the JX11.jucer file in Projucer and click the export button to open the project in your IDE.

The Finished Project folder contains the synth plug-in in its entirety, with added source code comments (it does not include the UI code from Chapter 13).

Want to know what the synth sounds like? Check out a few examples in the Audio Demos folder.
