+100!!!

It seems the OP is preaching to the choir. Its good to read these kinds of threads from time to time. Though, Sonar Platinum is 20% to 40% better then Professional.    

John Though, Sonar Platinum is 20% to 40% better then Professional.    

I am using Professional, although I've signed up for Platinum.  Just haven't gotten around to loading and learning it yet.
Can you say why you think Platinum is so much better?  Thanks.

First, the 20-40% better thing is a bit of a longstanding inside joke among those of us that have been around here for a few years... actually it seems to originate from even before my time - a legendary post from 2003. 
 
Second, with regards to version differences, the comparison chart tells all:
https://www.cakewalk.com/Products/SONAR/Versions
 
In short, Drum Replacer, Vocal Sync, Theme Editor, more instruments (23 vs 19), more FX (89 vs 56), and more PC modules (11 vs 5), zoom spectrum analysis on the quadcurve, more loops and sample content. 
 
 

You can see the main differences on the version comparison page.

In a nutshell, vocal sync, drum replacer, theme editor and numerous fx, instrument, and pro channel plugins. The first two I've never used, many of the fx and pro channel plugins I use all the time.
 
However, there are also a few differences not listed there, and you have to dig through the update history find them. Two that I know of which are very useful to me are the controller pane transform tool and the ability to create custom filter sets in the piano roll track pane.
 

I agree...
 

I agree too!

Thanks for the listings of things to check out.  I'll be busy!

In looking at the feature comparison between Professional and Platinum, I notice that the VX64 Vocal Strip and also the Percussion Strip are shown as only included in Platinum and not in Professional.  But I have both in my Professional edition.  Makes me wonder how many other errors there are.

Carry over from a previous version of SONAR you still have installed perhaps?
