I too would like to find a way to upgrade to Platinum from Professional, and/or at least acquire Rapture Pro and Z3TA+ 2.
I'm still relatively new to Sonar, but after trying a couple of other DAWs this past couple of days, I prefer Sonar.
Some other DAW UIs look better on YouTube for me, but I didn't like them in the flesh.
Just saying in case the right people are listening.
The idea of someone at CW saying `ah fu$k it!', and releasing everything else for free to registered customers, sounds like fun.
