First, does anyone know anything about this inexpensive plug called Expose (I think) which purports to find the "problem areas" in your mix for differing platforms??
 
And...
 
What the heck happened to "S" not splitting anymore??  Now It triggers the synth rack view.  And even if I unbind it...I can't find a "split" command to rebind it to.  Say it ain't so, Joe.
 

Never used 'S' to split. I came to use split a lot after the 'Smart Tool' became 'Popular!'
 
With that just press the 'Alt' key and place it over a clip and the scissors will show up.

2. "Split" (lowercase s) working fine for me. Using latest Sonar Platinum.
 

Weird this should come up, I couldn't get s to split for me either last night.
 
I offered some thoughts on Expose over in Deals. I think it's a simple way to get some info about your mixes, although I may not always take its advice.
 

I finally figured it out...sonehow s got bound with the synth rack.  And, after unbinding it i was trying to find a way to rebind it to split...but there is no split command to bind to.  But...if you just unbind s and dont bind anything else to it...you are good to go.
