Thanks, ElGato I appreciate the feedback.

I made the main song that I posted, using recordings at around 140 bpm. Some of them were beat matched from 120 bpm and some from 145 bpm. Mixed everything myself, and took samples from my synthesizer, and some RF sources. You're welcome to use it Boss, it's only about 3 mins though :/

I don't know about these other guys' music though, you have to ask them. But the one at the top was my first attempt at making my own dubstep music. Don't know if I'll do it again. Because it was a pain in the ass.

What programs do I use to make this?

Sony Acid pro (mixing/MIDI)
Sony Soundforge (sample editing)
Adobe Soundbooth (sample editing)
Camel Audio Alchemy (Modulation/Soundform editor VST)

Camel audio Alchemy is INCREDIBLE, it allows you to control the sounds with full range, and dynamic textures. You can modulate multiple samples and use them in the same multisample, which is playable via MIDI and has adjustable modulation knobs and modulation presets to control the modulation in realtime during recording..

Other great producer programs:
Reason
FL Studio
Renoise (Revamped modtracker)
