I can't find "R mix" in my X2 plugins.  I guess I have to download it as a VST.  Where's a website can I find R mix to download.
Or how else do I get it?
 
sonar X2, windows 8, sony viao i5
 
 

It's in your audio effects.  Same place as your Breverb, I believe.  You insert it into your track just like you would any other audio effect.

R-Mix was included with SONAR X2 Producer only. It was not included with Studio or Essential.

So I'll need to upgrade to Sonar Producer to get R Mix.  I tried downloading R Mix from a free ware site, but got tangled up with all their extra stuff they try to load on you.  I quit the download.

R-mix isn't free. You really mean you tried to download it from a site that distributes pirated software.

No point as you can't upgrade to Sonar X2 producer unless you can find a retail copy somewhere. X3 is the current Sonar version for sale but R-Mix isn't included anymore because Cakewalk have cut ties with Roland who make R-Mix.
