I didn't mean to imply that RB was slow to boot - it boots fast enough, maybe five or ten seconds, but at random times it decides to take another few seconds to "initialise accompaniment functions" which interrupts my workflow. Powertracks, on the other hand boots almost instantly and is ready for work. I've used PT since it was MIDI only and I still think it is THE best DAW for tracking and editing that I've ever found and that includes the expensive big names. In the final analysis, I use RB and PT depending on the task in hand.
