Eurorack Expansion Weekly

It’s a never-ending question: “Which module should I get next?” Usually followed by: “If I buy module XYZ module, what new sounds will it make possible? How can I use it to best advantage?” Since few of us live next to a well-stocked modular synth store with an experienced user on hand, I’ve decided to tackle this issue with an ongoing series of videos called Eurorack Expansion. I assume you’re starting with a semi-modular synth (like the Moog Mother-32) or small core modular system, although of course this info will be of use to experienced users as well. These movies go well beyond the simple “here’s what a filter sweep sounds like”, and instead dive into how each module works while teaching a variety of synthesis tricks and techniques along the way.

modules to be explored in the Eurorack Expansion courseThe journey starts with the 7-hour, 77-movie “Learning Modular Synthesis: Eurorack Expansion” course published through and LinkedIn Learning (release date: July 3, 2017). It discusses the important utility or “glue” modules you will need to get the most out of new modules you add, then demonstrates 3 very different modules each in the major categories such as oscillators, filters, modulation sources, and more (pictured here). Click this link to see the full course description and a table of contents of which modules and techniques are covered. A number of these movies have been made available free to everyone to check out the course. If you don’t already subscribe, you can get a 30-day free trial to by clicking through

After that course is released, I plan to continue releasing a set of videos each week, covering additional modules and exploring what can be done with them. You’ll find many of the videos go beyond the typical knob-twiddling demos, and explain both core and esoteric synthesis techniques. I’ll be covering both new modules and old, including ones I use in my personal system as well as interesting alternatives manufacturers have loaned me to check out. At the beginning of the first video in each set will be a chart showing its size, power demands, and price, including depths I’ve measured myself from the back of a module’s front panel to the back of the power connector or deepest part on the module to make sure it actually fits into your case.

Learning Modular patch color coding chartThe most recent videos released in this series are below; to see any accompanying text or playlists, visit this site’s Videos page. To the right is a chart of how I color-code my patch cables in all of my videos to make it easier for you to follow a patch. I also recommend you check out this article on setting up the core rack used for this series.

If you want even more information and want it sooner, you can become a Learning Modular Patron, getting access to these videos before anyone else, as well as additional explanations and discussions for each module plus bonus videos & information. Learning Modular Patrons will help choose which modules are covered and in which order, and get first crack to modules and related studio equipment I’m selling.
