Definitive guide to semi-modular analogue synthesisers published

With a forward by Hans Zimmer, Patch & Tweak with Moog is a definitive new 200 page reference on Semi-Modular Analogue Synthesizers.

The second in the Patch & Tweak series from electronic musician, author and designer Kim Bjørn, it’s the result of more than a year of extensive collaboration with electronic music artists, both established and emerging, as well Moog employee-owners. 

The tome covers synthesizer techniques, creative patch ideas, sound design tips, professional artist interviews and in-depth discussions with Moog engineers. Readers will get an inside look into the Moog factory in Asheville, North Carolina.

The book focuses exclusively on Moog’s line of semi-modular analogue synthesizers: Mother-32, DFAM, Subharmonicon, Grandmother, and Matriarch – all inspired by the original analogue circuitry of the first modular synthesizers developed by Bob Moog in the 1960s. 

The  synth company’s introduction of the Eurorack-compatible Mother-32 in 2015 made Moog modular sound more accessible than ever, sparking something of a modular renaissance. In the five years since, the Moog semi-modular family has expanded to include an instrument designed for percussive pattern creation (DFAM), expressive monophonic and paraphonic keyboard synths (Grandmother and Matriarch), and the new polyrhythmic Subharmonicon. PATCH & TWEAK with Moog captures and celebrates exactly why this collection of instruments is renowned throughout the music industry as quality sound design and performance tools.

There are contributions from composers, producers, and performing artists like Suzanne Ciani, Trent Reznor, Lisa Bella Donna, Paris Strother, Hannes Bieger, Stranger Things composers Michael Stein and Kyle Dixon, and Moog synthesizer co-inventor Herb Deutsch. Plus, the Moog employee-owners who conceptualised, designed, engineered, built, and brought these instruments to life.

“This book offers an empowering experience for artists at any point in their journey of exploring synthesis and sound,” says author Kim Bjørn. “Whether you are new to modular or looking for creative perspectives to expand your process, this book will inspire you.”
