Aloha fellow note benders, mixers, etc;
Recently purchase Sonar X2 Essentials after much research, my recording/mixing/etc last 20+ years mostly done with Roland products, after using Sonar X2 Essentials I wanted to mess with vocal tracks and noticed I need R-Mix to do what I want which is in Sonar Producer, is there an upgrade or do I need to sell X2 Essentials and buy Sonar X2 producer to get the R-Mix feature?  Is there a similar plug in?

R-Mix was included with X2 Producer. That has been superseded by X3 which doesn't have R-Mix bundled with it.
 
Your best hope is to see if you can find a retailer still selling a boxed version of X2 Producer or buy R-Mix as a separate product. I don't know of anything similar although if there is one someone on here will know about it.
 
 

That is something you may want to contact CW about. There was a free upgrade from X2 Producer (retail) to X3 Producer, BUT I am not sure what the time window is on that offer. As Karl said, if you can find a boxed version of X2 Producer (upgrade), you may be able to get both X2 Producer and X3 Producer in one purchase; but PLEASE contact CW customer support and ask first. I would even tell them your situation and ask if they can extend this offer for you if it has expired.

Edit: I just went searching for R-MIX stand alone and it was ~$200! X2 Producer also has "V-Vocal" which is another nifty plug-in that was not continued in X3, so if you can take advantage of the original post you will benefit the most.

I accidentally duped that post because the forum wasn't taking it, sorry.

Thank you both for fast response to this and helping me with this, been shopping and, yup! $499 at cakewalk, $499 at amazon,  $299 open box at amazon almost bought, feel uncomfortable with open box, (registration, etc) you never know with software, ebay $299 x1-x2 upgrade, so I need to sleep on this one, I'm so green with this, been doing MIDI hardware so long with lots of keys, modules, etc. but know I need to do this, thanks again......
