This post illustrates the challenge of being a graet all-around product. The staff view complainers often claim Sonar is too focused on EDM. Every successful creator of just about any genre relies on more than the instant gratification features of any DAW. Sonar is setup well to create EDM. It's not as well suited for certain aspects of EDM production as Ableton and Fl, but it's not like they are giving you a bassoon and a timpani and telling you to construct drum and bass either. EDM, like any genre, still takes work to create something beyond cookie cutter, template based crap. Presets can be useful, but get boring when countless people use the same patch for very similar songs. Cakewalk's synths can be used with any genre (including death metal polka and its lesser known cousin Gangsta Packpack Zydeco) , particularly if the person can go beyond presets. Z3ta has been used on commercial EDM recordings. The guy who makes Syntorial has done tutorials showing how to recreate well known EDM songs using Z3ta.
As for loops, they can be useful, but many serious producers who do use loops often find/create their own from sources that were not necessarily made specifically for EDM. Logic comes with a fantastic set of loops, yet they mostly just sit on the computer at our studio except for just playing around with ideas.
The things that make a great EDM tune are going to have lots of overlap with other genres. It starts with a great performance. Sonar can't do that for you. Next comes a great mix. Sonar can do that for any genre. I can mix any genre with Cakewalk stock plugins. Yes, I use third party too, but more and more of my mix is pure cakewalk. Even when it comes to virtual instruments, Sonar is capable. I was just dinking around making a trap beat in the studio using nothing but cakewalk products and a few samples for things like the commonly used chants (the 'hey' used in songs like Katie Perry's "Dark Horse" for example) and a rapper asked if he could use it. I admit the same thing would have been easier in FL, but there are so many more things I would not use FL for. For me, regardless of genre the bulk of my efforts are going to be in the mix phase so that trumps included synths and loops.
