Which producers use what music software?

Different producers use different software to their acquired taste. I use Ableton live suite and have done for a year. Deadmau5 uses fruity loops. Prodigy uses reason, ableton and logic. Ian Carey uses Steinberg Cubase 5. As far as i know of it, vast majority use Logic pro as it is pretty industry standard.

It's all about what you like and etc. I have to say that ableton is my favourite because it's so simple and intuitive as well as you can use it to dj with. You can do a MASH up on the fly. It would be my choice for a lot because it truly has it all! It is an extremely flexible program for alot of today's needs

Logic is extremely professional software used by a bunch! Ranging from hardcore producers - Tiesto/Prodigy - to people not as well known but still amazing producers - John B Beta, Jordan Suckley. It's a great rock solid producer program!
