[EDIT: I mean the one before the previous one ;-)]
What I love about modular:
The gritty analog sound. I may be in the minority here, but I'm sensitive to, and interested in, sound texture down to its finest grain. I'm not disparaging digital sound - it can be beautiful too in its own right, but in emulating analog, it's always a bland imitation, to my ears. Now I love digital sound design as well, because there are many things only digital synthesis can do, but I have the computer for that - a much cheaper solution, even though I'll admit it's less fun to use (It's also more efficient). Anyhow, when I want to feel my hair stand at the literal sound of electricity, only analog synths, and more than anything else, my Eurorack, give me that.
The geekiness of handling signals, coming up with new interesting ways of signal processing, and that a modular synth is half way between an electronics lab and a musical instrument. As I often say: just making music instead of noise is already a feat. Making good music, in those conditions, is a miracle and I have utter admiration for those who manage that (me, I make a few tracks with the modular and integrate them into more conventional instrument tracks to make a song - and I edit a lot afterwards). Getting elaborate music (or just pleasing sound) out of basic electronics with just the use of my brain and hands, is a joy and a marvel.
Sound design !!! (This is the logical conclusion of the previous two points)
The physicality of it. (VCV is great, but it doesn't thrill me as hardware does. It's a tad cheaper though, so it has that going for it ;-))
The fact that my studio looks like an Appolo cockpit. I am a technological peacock.
The creativity of module creators. (I wish I was better at electronics myself. I know I should make the time to learn that but I don't.)
The discussions: I love discussing many things, from art to philosophy to psychology to sciences to engineering, and here I find enough geeks to indulge my passion for splitting hair and talking endlessly about a subject; discussing our tastes, reviewing gear, sharing tips and tricks...
The vibrant community (this is the summary of the last two points ;-))
I'll let you know if I think of anything else.
