I frequent a few music production subReddits and one of the most common questions newbies ask is "which is the right DAW for me?" Sometimes they list a few DAW's they've been pondering over and invariably people chime in with their suggestions.
Nobody ever mentions Sonar. I throw it into the mix and the response is usually "oh I've heard of that, is it any good?" or "never heard of that one, will check it out."
Bear in mind that Reddit has a notoriously young user base. What I get from this is that Sonar is not doing so well in terms of visibility among the young crowd and Cakewalk really need to fix this problem as part of their long term strategy, and I'm sure they are talking about it. That's going to mean catering a little more for the electronic/EDM crowd than they are now, by borrowing/expanding upon some of the features that other DAW's have implemented for that crowd. Things like the global modulation sources of Bitwig, or the drum rack of Ableton, more features geared toward pattern based arrangement and better automation capabilities. Sonar has a solid user base of older muso's who use the program almost as a tape machine to record more traditional forms of music, but it's not really doing as well as it should among younger users who, regardless of the genre they play, are incorporating synth and EDM type elements into their modern productions.
