I have a couple of synths that are semi-modular. I've thought many times about going full-blown down the rabbit hole, but modular synths seem to be one of the most expensive money sinks you can get into in music, and I already have way more gear that I don't use enough as it is, so I've held off.
Electronic music is probably my second or third favorite genre. I spent a lot more time on it than metal especially in the 10s. The vastness of it is so daunting though, I still barely have a handle on it even compared to metal. The synth-wave/dark-synth movement in the past decade has been one of my favorite scenes, with so many great artists like Perturbator, Megadrive, The Midnight, Lazerhawk, Volkor X, FM-84, Dead Astronauts, NINA, etc.
