SONAR X3 doesn't have the ProChannel. That's available when you upgrade to SONAR X3 Studio or Producer.
 
Studio has two ProChannel modules but you can buy more
 
Producer has 8 including the new Tape Emulator and the QuadCurve EQ Zoom. And you can add more as well.
 
If you were to upgrade to SONAR X3 Studio, your modules would all work. When we announce you should look at the comp chart and see what's worth spending the extra money on. 

Personally I will go for the full enchilada.
 
I was asking because they are several forumites expressing frustration about not getting another x2 update. I was just thinking of a less expensive way forward for them if they are more interested in the core improvements than the added plugs.
 
I am looking forward to release and the flood of excited posts as well as the to be expected bug reports
 
I'm hoping the few issues I have with x2 are sorted.

@Tom Riggs, an excellent idea for those who balk at the notion of paying for the full release of X3 - for whatever their reasons.

I guess the number of buses are still limited but the drop of "Essential" and changing the number of plugins, etc. to unlimited are great news for someone like me who proudly uses the Essential version with mostly third-party plugins. Thanks!

I'm saving for Producer, as usual, but it looks like they really did raise the bar for the baseline version.   Well done.
 

I was wrong. It says "Mix with unlimited effects, sends and busses."
