DP has always been my "Mac only" program of choice as opposed to Logic or pre-Windows Pro Tools. It's a fine program, particularly for audio-for-video, but its workflow is
very different from Sonar's. That doesn't mean it's good or bad, but having used DP since its MIDI-only days, I'm comfortable with it. I don't know what I'd think if one day I just decided to switch from Sonar to DP.
For the record, neither MOTU nor Cakewalk paid me for that "review"
