We came across this book, and author.
We assumed it was of a low quality, but it turns out it's AI written garbage!
It is continually filled with factual errors, and the types of "Facts" that only an AI would get wrong. Conflating feature sets from similarly named synthesizer models from other manufacturers. Claiming certain models were used on soundtracks several years before that synthesizer/keyboard was released.
This is a piece of made up bullshit. Don't buy it. Do not give this con artist your money.
YOU WILL BE DISAPPOINTED!
This same grifter has a "History of Synthwave" which will be just as terrible.
