I'm like you, Gavin. Traditional instruments and samples of traditional instruments for the most part. But regardless of the methods of tone generation, electronic music is all about MIDI, and SONAR does MIDI as well as anyone and better than most.
I gather that Z3ta+ and Rapture are favorites among the EDM crowd, along with Massive. Zebra suits my own needs better, as it's versatile enough to satisfy a broad range of genres. It's pretty much the only conventional synthesizer I use.
It should also be noted that the secret weapon for people who knock out generic pop EDM quickly and easily is Nexus. It's a rompler, and overpriced IMO, but it's ready right out of the box for one-note EDM masterpieces. If I was ever offered a paying gig doing that kind of music, I'd invest in Nexus and let them think I was working harder at it than I really was.
