The description of that reads spot on… agree that on the face of it that it appears to go deeper than the Ableton book. I have (and enjoy) the book though and feel it’s possibly aimed at a different market.

At a very high level (and not regarding the amount of content, minimalness, etc) the De Santis book is almost all about electronic music production in a DAW, and the Butler book all about performance/improvisation of electronic music. The title suggests that it’s for DJ/laptop performers, but after my brief look through, it seems useful for hardware sequenced performances as well.
