Audio engineer/ Data ScientistThe layout of the book is amazing. I liked how the book starts with familiarizing the reader with the pre-trained models and their configurations. I enjoyed the in-depth explanation of "one-hot encoding" sequences and the changes depending on the model. The python files are clean and very well documented. I was able to train two separate Melody RNN models one w/ basic config and the other w/ attention config. I deployed a simple Magenta.js application with the base model and had fun generating melodies with the trained model"attention config" in Ableton Live. The coolest experience overall was playing a melody in Ableton and receiving a response "generated melody" from my trained model via Magenta midi interface.Some headaches:* I had trouble setting up the conda environment by the book on a "2020 mac Catalina." I successfully created the environment and installed the dependencies following the second branch on the git repo "magenta-master" for magenta 2.1.2. If you're on a new computer I would recommend using the branch mentioned above to follow along with the book.* The coding videos were helpful to see someone using the command line. I would have liked to see a few video walkthroughs "with audio" on the chapters Magenta.js and in-depth interaction with magenta midi and Ableton.Findings:I trained a Melody RNN w/ attention config but wasn't able to initialize it on the browser with Magenta.js. This is a current inability and Magenta is tracking this issue. I was able to initialize the model I trained with the base config.

I'm a former Google employee and musician and have been following the Magenta research project since its inception. I am often surprised by how many questions show up on the public Magenta mailing list from musicians and programming hobbyists who are struggling with the basics of music generation using the open-source Magenta code. The Google team is responsive to questions, but it seems that many people have difficulty getting the basics working. This book fills that gap and provides something like a detailed "user's guide" to Magenta, along with a general overview/explanation of the music generation techniques used in Magenta.Specific topics include how to use the recurrent neural network (RNN) models in Magenta to generate monophonic music, polyphonic music, or drum sequences, how to use variational autoencoders (MusicVAE and GrooVAE) to control music generation, and using WaveNet and Generative Adversarial Networks (GANs) for generation of raw audio. Magenta.js is introduced for using Magenta in a web browser. Along the way the book introduces concepts such as convenient music representations for generation, public datasets such as the Million Song Dataset, and how to train custom Magenta models.The book is quite practical, with concrete code examples and instructions on the myriad issues that arise when tying to get Magenta to work, such as needing to install GPU drivers, setting up python conda environments, preprocessing MIDI files and converting to Google's "protobuf" format for use with Tensorflow, hooking up FluidSynth to listen generated MIDI, etc. Some of these instructions may go out of date over time, but for now they seem quite useful for people with less experience in software engineering, deep learning, or audio software.A pleasant surprise was the inclusion of a small number of exercises at the end of each chapter (e.g., "what are the advantages/disadvantages of different symbolic music representations?"), which I could see as helpful in preparing a specialized university seminar on music generation (answers are at the back of the book, so these questions are also useful for self-study).The book only provides a cursory look at the algorithms involved in music generation, so for details the reader will need to refer to the original research papers and blog posts from the Magenta team. It does provide a basic introduction, which might be all that is needed for the target audience of people who just want to start generating music.Two items seem to be notably missing from this book: 1) discussion of Coconet, the Magenta team model behind the Bach-generating "Google Doodle" in March 2019, and 2) discussion of Transformer models such as Music Transformer. I think we can blame Google for the latter, as the Music Transformer code doesn't yet appear as part fo the Magenta open source code base for some reason. The first is more surprising, but perhaps it will be added in a second edition of this book.Overall, I think this book does a great job filling in the gaps for users getting started with Magenta and music generation, and I highly recommend it for that audience. The ideal reader of the book already has some programming experience with python; I think a musician new to coding would still have a difficult challenge even with this book as a guide, but the highly-motivated hobbyist would probably have success.My main criticism is a bit superficial: I don't like the design of Packt press publications. The typesetting looks too much like a generic Microsoft Word document using default setting. The table of contents in particular is simply ugly and looks like standard self-published fare, and the font used for section headings is uninspiring. The greyscale figures in the print version are hard to read and don't do justice to the color figures in the PDF version of the book. Usually I prefer print books to ebooks, but this might be a case where I prefer the opposite, just because of the quality of the figures. I have enjoyed the content of a couple recent Packt publications, but I would encourage the publisher to improve on presentation in the future.

Ich arbeite gerade mit dem Buch an meiner Bachelorarbeit und finde es super, dass man die ganzen Code-teile ganz einfach aus der Docu kopieren kann, das macht das parallele Anwenden des Code sehr angenehm.Da ich leider wenig Vorwissen zu Python habe, muss ich mir viel nebenbei anlesen, einige Äußerungen sind auch etwas kryptisch, es werden Begriffe eingeführt und erst zwei Seiten später erklärt - also das geht noch besser :) Vermutlich liest sich das noch besser, wenn man schon Vorerfahrung mit Programmieren hat.Und es sind auch ein paar Rechtschreibfehler drin, die könnte man in der nächsten Ausgabe dann auch mal korrigieren.Ansonsten super Buch und toll, dass es eine Anleitung gibt, mit der man ein selbstlernendes Kompositionssystem bauen kann!
