I started making music when I was 14 on a laptop and thats it. How you make music depends on what your writing, and what you have to work with. The great thing about electronic music is you dont need alot to create something. You can tweak almost anything to sound a certain way.
I use FL as my DAW and my sequencer. Have been since I started. Nothing will ever take FL away from me haha. I also use Abelton Live 7.
I use alot of VST synths from companies like Native Instruments, Cakewalk, reFx, etc. I also have a Roland MC-303, a Moog Little Phatty, microKORG, and I use things like the Nord Lead 2, Nord Modular, Roland MC 808, depending if I'm at my studio or not. But again, its what you do with what you have, not how much you have.
A midi controller or trigger controller is almost a neccesity. I use an M-Audio Axiom 61 and an Akai MPD32. Both great controllers.
The quality of your sound is also a big thing when writing music. Making sure that all your sounds come through nice and clear, with as little mud as possible so a set of referance monitors is a good idea. I'm currently using a set of M-Audio BX8a Deluxe monitors.
