As a bit of a preface, this series will focus on the Eurorack modular format; there are other formats that use patch-points. Eurorack is currently the most popular, by far. I’ll be using “Eurorack” and “modular” somewhat interchangeably, except where I specify that something is exclusively true for the Eurorack format, such as voltage specifications or physical measurements. You can assume that any module I mention in detail in this series is built according to (or compatible with) the Eurorack standard unless otherwise stated. Synthesizers like Jupiter 8, Minimoog, Minilogue, Prophet Rev2, Oberheim OB-6, that cannot have any parts replaced with a different part.
If you make electronic music, you’ve likely stumbled across modular synthesizers. You’ve no doubt seen videos of blinking lights and rectangular panels connected by masses of cables, sometimes being deftly manipulated by hands reaching from off-screen, other times generating music without any human intervention at all. If you’ve felt a sense of wonder when watching these machines bleep and bloop, then you’ve tapped into the heart of the modular community. A constant sense of wonder, surprise, and discovery. Filling a rack with modules can be a deeply personal journey toward discovering your unique sound and style. Modular requires a lot of knowledge up-front and can seem overwhelming to a beginner.
Not to mention the "outgrows your Eurorack case" part. In Euro, this can get spendy really fast, given the cost of cabs, then there's power, power distro, more screws, more more more...
In AE, you get too many modules, go "eh...", and just order another case + ribbon, and if you need it, a Master or case connector. And while the Eurorack user's Magic Plastic goes up in a ball of smoke and those little burnt plastic stringy soot things, the AE user gets their new case and bits and then has ample money left over for pizza and beer. And then some.
Probably goes with the "expensive AF" point, but running out of case space is the sort of thing I and others on MG caution about constantly because in Eurorack, that's sort of a "special-circumstance expensive" which new users can avoid by going with a bigger case than they think they need at first...or risk hitting that wall and dropping more on a second cab. But again, with AE, the suggestion would be more along the lines of "get what you need when you need it" with no worries about case expansion, etc.
