SONAR
BIAB
Melodyne
Kontakt and other softsynths
Goldwave

that's not even FIVE, I guess!
I do have and use a lot of effects plugins in Sonar

most of my recordings use a mic, a preamp, a hardware compressor, then I mostly use my keyboard with audio outs, so i don't even use softsynths that much.

I use BIAB for scractch recordings as a guide, I use sonar for most everything else. goldwave for mastering.
