I would not be so sure that upgrading to Platinum will solve problems you've had with previous versions of Sonar. Although these old versions reside on your hard drive they are not influencing any current version when you run Sonar. The problems you have sound like that are related to settings you have for your sound card. Also, a big reason for the drop out problem where the engine stops can be activity from background programs that run while you are in Sonar. Reaper might not be a problem because it does not stress your resources as much as Sonar might. I would seriously look at what is running in the background especially things that use the internet or virus scanning, etc.
I do not have this computer connected to the internet, Therefore no virus software, no scanning go on and no background programs running.....made sure of that when I built it.
Boot up programs are at a bare minimum. Just what it needs to boot and nothing else.
It is not overclocked and there are NO GAMES on it or even played on it.
It is strictly and only a Music DAW Computer.
Also I never said that these older versions
were influencing any current version.....I just said that I have them......nothing more.
So, nice thought and I thank you for them.....but I am ahead of you on this one....
