These days you will never ever get signed to any sort of major label, and probably no minor labels unless your using Massive for your baselines. And sure, you can make some okay shit with freeware, but your seriously wasting your time unless you want to shell out hundreds of dollars for Massive/Sylenth/Etc. It seems to me the only ways to get signed to a dubstep label is to either buy a shit ton of dubstep loops because you can't make them yourself, or spend all your time trying to make halfway decent bass with halfway decent synths and never get anywhere. Literally every single prominent dubstep producer uses Massive. I just watched 5 hours worth of interviews, and allll there people say they use Massive. IDK what the fuck they got started with, but Datsik sure as hell didn't get where he was with TAL Noisemaker and a bunch of BPB plugins.

That's my take on this shit anyway, if you disagree then help me out by giving me one example of someone who got anywhere without shelling out serious money for plugins. It's more than frustrating to realize that no one can ever make it in music as a teen, unless your parents are rich or they really, really like you or you somehow have a crazy job at 16 and you can sped all your money on software.
