Reply to Looking to get started making originals and remixes, which programs?

I'm looking into getting some programs so I can start making my own music(remixes as well as originals), with the main interests being electro house, progressive house, and brostep/dubstep/whatever you want to call it.

What programs would you folks recommend I look into? I know Abelton Live is used by a lot of people, and I've been told programs like Massive and FM8 are used a lot for creating different sounds or synth styles. One track in particular that I have ideas for a remix is Unison by Porter Robinson. When folks remix tracks, I assume they don't use the original mix to pull parts from and use with their parts. This was another part of my question, which is how people get the isolated pieces from another track for remixing.

For example, the KDrew remix of Somebody That I Used To Know(link below) features an isolated vocal line where there was guitar also playing in the original. I didn't believe it was possible to isolate instrument tracks from a prerecorded mix.


If you could offer me some advice in these areas it would be much appreciated!
