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.

Looping the generated MIDI

Now that we can send generated MIDI to a DAW, let's have a look at how to loop the generated MIDI. This opens up many different use cases, such as building a system that generates music continuously. We'll first have a look at how to loop NoteSequence. We'll also cover how to synchronize Magenta with a DAW using a MIDI clock, which is important in long-running live music systems.

Using the MIDI player to loop a sequence

In this example, we'll be using the player instance from Magenta to loop a generated NoteSequence, by copying the sequence and playing it at a later time, before the player ends its playback.
