I’ve only dipped my toe into modular synths, lest I unleash another hobby I don’t have time for. This book has a ton of concrete examples for three of Korg’s modular synths: the ARP 2600 M, the MS-20 Mini, and the Volca modular. Of those, I’ve only got a software version of the MS-20, so I haven’t done much actual patching.

The book is divided into sections about oscillators, filters, modulation, envelopes, etc. with lots of explanatory diagrams and lots of examples. Every few pages there is a long-form interview with a musician who uses one of the modular synths covered in the book. They’ve done a pretty good job getting a diversity of musicians, but of course it’s a mite biased towards featuring people who can afford to buy synths.

This would be a good introductory book, but for more advanced users it’s going to tread a lot of familiar ground. Either way, it’s very pretty, and it’s quite well produced.
