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.

Training Magenta Models

In this chapter, we'll use the prepared data from the previous chapter to train some of the RNN and VAE networks. Machine learning training is a finicky process involving a lot of tuning, experimentation, and back and forth between your data and your model. We'll learn to tune hyperparameters, such as batch size, learning rate, and network size, to optimize network performance and training time. We'll also show common training problems such as overfitting and models not converging. Once a model's training is complete, we'll show how to use the trained model to generate new sequences. Finally, we'll show how to use Google Cloud Platform to train models faster on the cloud.

The following topics will be covered in this chapter:

  • Choosing the model and configuration
  • Training and tuning a model
  • Using Google Cloud Platform
