I've been producing music since about 1998. I got introduced to electronic music about a year prior, and immediately started DJing, my interest in production grew out of that.
Unless you count poking my keyboards, no. I do most of everything with the mouse/qwerty keyboard.
FL Studio, Reaktor 5, Bome's MIDI Translator
Lots of toy keyboards, and DIY synths, mostly everything is modified in some way. I get new gear all the time, but lately I have a thing for toy samplers from the late 80's and early 90's.
Lots of David Carretta, and anything on International Deejey Gigolos.
David Carretta - Le Catalogue Electronique
Tobias Schmidt - Destroy
Dave Tarrida Plays Records - a mix, but still tops my favorites
David Carretta, Terrence Fixmer, Anthony Rother, Chris Leibing, Sven Vath, Millimentric, The Hacker, DJ Hell, so many more. Too many to list here.
Stylistically, It's hard to pin down. All electronic, usually dark and/or dirty. Lots of analog and vintage sounds. Ranges from ambient soundscapes to aiming straight for the dancefloor.
I break software. (I do quality assurance.)
