I’ve started out with FL Studio 3 back in 2004, then switched to Reason in 2005, experimented in Cubase in 2006 for a bit and hated it, got in Logic 8 in 2007 throughout 2011 and loved it (with a bit of Pro Tools sparkled in between, and profoundly hated it), then got back in Cubase in 2012 and stuck to it since. I have tried very briefly other DAW’s, but Cubase Pro is just my way to go.
The versatility, editing options, workflow, tools, interface, everything is to my taste, especially starting with version 6 and now with 8.5.15. When I open it, there’s a little guy in the corner which says “welcome to the pro paradise, enjoy” and hands me a cold smoothie. Yeah, that’s how good it tastes.
