Overview of this book

Tkinter is the built-in GUI package that comes with standard Python distributions. It is a cross-platform package, which means you build once and deploy everywhere. It is simple to use and intuitive in nature, making it suitable for programmers and non-programmers alike. This book will help you master the art of GUI programming. It delivers the bigger picture of GUI programming by building real-world, productive, and fun applications such as a text editor, drum machine, game of chess, media player, drawing application, chat application, screen saver, port scanner, and many more. In every project, you will build on the skills acquired in the previous project and gain more expertise. You will learn to write multithreaded programs, network programs, database driven programs and more. You will also get to know the modern best practices involved in writing GUI apps. With its rich source of sample code, you can build upon the knowledge gained with this book and use it in your own projects in the discipline of your choice.

An overview of the chapter


Our goal here is to build a programmable drum machine. Let's call it the Explosion Drum Machine.

The drum machine will let the user create an unlimited number of beat patterns using an unlimited number of drum samples. You can then store multiple riffs in a project and playback or edit the project later on.

To create your own drum beat patterns, simply load some drum samples (which can be any audio file with a .wav or .ogg extension) using the buttons on the left. You can design your beat patterns by clicking on the buttons on the right.

You can decide the number of beats per unit (BPUs). Most Western beats have four beats per unit, waltz would have three beats per unit, and some Indian and Arabic rhythms that I composed on this machine had 3 to 16 beats per unit!

You can also change the beats per minute, which in turn decides the tempo of the rhythm.

A single pattern like the preceding one constitutes a single beat pattern. You can design multiple beat patterns by...
