Chapter 8: Magenta in the Browser with Magenta.js

1. We can train models using TensorFlow.js, but we cannot train models using Magenta.js. We need to train the models in Magenta using Python and import the resulting models in Magenta.js.
2. The Web Audio API enables audio synthesis in the browser using audio nodes for generation, transformation, and routing. The easiest way to use it is to use an audio framework such as Tone.js.
3. The method is randomSample and the argument is the pitch of the generated note. As an example, using 60 will result in a single note at MIDI pitch 60, or C4 in letter notation. This is also useful as a reference for pitching the note up or down using Tone.js.

4. The method is sample and the number of instruments depends on the model that is being used. In our example, we've used the trio model, which generates three instruments. Using a melody model will...
