Want to get into production/remixing Whatever I've done so far, I have used GarageBand. It's nice and easy to use, but want to move up to something more sophisticated What is the best to learn/use? Pro Tools?
I recommend Ableton Live Suite. I bit of a learning curve but if you're dedicated and focus on learning it, it gives you so much possibility. Also, videos on youtube help alot. It can also be used for DJing.
Pro-Tools Looks Excellent http://www.avid.com/US/products/Pro-Tools-Software I Imagine (Presume) you have a Mac as you have used Garageband; But; if you have the Money Available; due to the Virtually Limitless Capabilities within Ableton Live Suite 8; I would have to Recommend Ableton over Pro-Tools; (Ableton is Available for Mac); If you were talking about Ableton VS Logic; I would still Recommend Ableton; but it would be a Different Argument
I started on Fruityloops a long while ago, and now it's been gaining a lot of popularity. Laidback Luke, Deadmau5, Afrojack, Madeon, & Arty are some of the big names that use(d) it. I think Deadmau5 & LBL uses Ableton now. Ableton and Apple's Logic are the other monsters in the DAW (Digital Audio Workstation) world. Logic is used by Swedish House Mafia, Paul Van Dyk, & Ferry Corsten, that I know of. I assume Steinberg developed CuBase to compete with FL Studio, Logic, & the like. I've also heard a lot of good things with Propellerhead's Reason, but have no experience with it. Although I have ProTools & Nuendo, I use them for sound design and post-production in film instead of music production. But that's just me, since the EDM genre is more loop-based... My advice to you is to download some of the demo's, check out videos on Youtube, and feel out which one suits you. Certain DAW's do things better than others...I also suggest you learn more than one software.
I'm partial to ableton. Reason is nice. The learning curve is pretty ridiculous though. Whatever you end up choosing, I recommend checking out "The dance music manual" by Rick Snoman. Really informative stuff there.
I have Reason 5 (and have been using it since Reason 2); and it is Fabulous for Composition; but for Production and Remixes I still Vote for Ableton; and there are No Facilities for DJ'ing with Reason; it also doesn't Support VST's;
