I'm sure I'm just reiterating a lot of posts here but here's my 5 cents:
Music theory is probably the most important thing any musician can have in their mind. I use the term musician because if you a producer for say, a band or pop singer, most of the musical work is done for you, especially with bands where you are just taking recordings and mixing and mastering them.
Also, the more important thing to realize about music theory is that you can't learn it in a month. Music theory takes years to fully understand every little intricate aspect of theory. Even musicians that have been practicing for ten, twenty, thirty years sometimes don't fully understand theory, but they know what sounds right. That's another point is that all humans already have the extreme basics of music theory integrated in your brain, where you know instinctively what sounds right. If you play one note wrong on a scale you've never played before, you know it's wrong and you try to fix it. But the fact that its takes a long time to study should never stop you.
Music theory is simply that, a theory. They are rules that have been developed from some of the greatest composers of all time, being Mozart, Beethoven, and many others. These guys used all kinds of modulations and countings, and using harmonics to make notes sound diffenrt than they actually are. This shows how using theory to BREAK theory is the best thing you can do. Things like secondary dominants and key modulations within songs are very fun to do, sound fully original, and yet, they are derived from theory. There's a very good reason why these classical composers were used to develop theory, give their music a listen some time and you'll hear why.
But for electronic musicians, the most important thing you should all take from theory if you chose to study it is chord writing. It's the bones of what we believe (that chvrches reference) when it comes to melody writing. If you come up with a great chord progression, writing a melody on top of it becomes so much nicer and fits better. If you take a melody you wrote already, you can easily analyze the notes in the melody to write a progression underneath it within ten to twenty minutes.
Theory may just be a theory, but everything in it can be done backwards, forwards, sideways, and flipped inside out. Theory goes beyond just knowing how to write chords, rhythms, and key signatures, but rather it's a nearly endless array of rules and structures to ENHANCE your composition. Theory is incredibly important to know if you want to be a better musician. If you want to use the rules to break the rules (when in fact you're just using another part of theory), you need to know theory.For those of you who are interested in studying theory, in case it shan't been posted already, here's the most helpful website I have ever found on theory, it saved me in my theory classes in school:
