Cubase 5 as main sequencer with NI Massive as main synthesizer for nearly every sound. NI Absynth to create some ambient sounds. Most of the Waves plugins. FabFilter Pro-C as main compressor because it really sounds brilliant. 2C Audio Aether, Waves TrueVerb or Waves IR-1 (to use some King Tubby impulse reflections) as reverb effects. And some built-in Cubase effects (like the gate, envelope shaper, da tube, ...) and free effects. Izotope Ozone and PSP Vintage Warmer to master tracks.
Think I mentioned most of the stuff I use, but most likely I forgot some..
I also use FL Studio now and then to quickly lay out an idea. And Reason when I feel like playing with patch cables!
