Hands-On Music Generation with Magenta

By: Alexandre DuBreuil

Overview of this book

The importance of machine learning (ML) in art is growing at a rapid pace due to recent advancements in the field, and Magenta is at the forefront of this innovation. With this book, you’ll follow a hands-on approach to using ML models for music generation, learning how to integrate them into an existing music production workflow. Complete with practical examples and explanations of the theoretical background required to understand the underlying technologies, this book is the perfect starting point to begin exploring music generation. The book will help you learn how to use the models in Magenta for generating percussion sequences, monophonic and polyphonic melodies in MIDI, and instrument sounds in raw audio. Through practical examples and in-depth explanations, you’ll understand ML models such as RNNs, VAEs, and GANs. Using this knowledge, you’ll create and train your own models for advanced music generation use cases, along with preparing new datasets. Finally, you’ll get to grips with integrating Magenta with other technologies, such as digital audio workstations (DAWs), and using Magenta.js to distribute music generation apps in the browser. By the end of this book, you'll be well-versed with Magenta and have developed the skills you need to use ML models for music generation in your own style.

Creating a Magenta.js web application

Now that we have introduced the concepts surrounding Magenta.js, we'll be creating a web application using Magenta.js. Let's create a web application where we generate a trio of instruments (the drum kit, the bass, and the lead) using MusicVAE, where we can change the lead instrument for a GANSynth-generated instrument.

We'll be building this application step by step. First, we'll make an app that generates instruments, using GANSynth. Then, we'll create an app in which we can sample a trio sequence. Finally, we'll merge the two apps together.

Generating instruments in the browser using GANSynth

For the first part of our example, we'll use GANSynth to...
