I am reading this thread with with increasing astonishment. In stead of being happy that Sonar/Cakewalk lives on, people are moaning and complaining and "gnashing their teeth". I mean - Really?
I am an user of Sonar from the time I got it with my (already defunct) EMU 404 PCI card. Isoon "upgraded" to Home Studio 6 XL and finally 8 Pro. After that I went with all updates and upgrades (with exception of X2/3). I payed for all those updates and upgrades, until I "jumped ship" to Cubase last year.
I think it's wonderful that Sonar Plat is free now. I think this will attract a larger group of users than Sonar ever had in his history. That will certainly benefit all current users, because it will put Sonar "on the map" again. Chances are big that new plug-ins (and programs) from other developers therefore will be compatible with Sonar. That would certainly be not the case if Sonar was drifting in oblivion.
And top of that... It's a sound move. Just give away an good DAW, and charge for (upcoming and existing) expansions. Those people get Sonar Platinum for free, and I suspect the next move is to sell Z3TA2+, Rapture, Dimension Pro and other plugins (that most of us already have in our account), to earn money that way. It would not surprise me if Platinum Pro will stay free, and gets regular updates, while new plug-ins and maybe soft-synths will be developed.
And no - I am not "salty" in any way that Sonar Platinum is free now. Why should I?
