Found it. Had to undock it multi dock. Not obvious at all.
I have avoided learning the X GUI for a few years and I'm not enjoying the process. So far I still prefer the older GUI. Don't see yet how shuffling all the stuff around and making familiar work flows unfamiliar has made SONAR any better.
Is the controller pane gone now in MIDI CLIPS view? Again, not better, IMHO.... Yeah I know, "progress" just like MS does (I hate the Server 2012 R2 interface too... :-( ). I'm trying to force myself to use X3 and NOT revert to the familiar GUI in S8.5p but it's really stiffing my creativity. I understand now why so many of my forum friends have abandoned SONAR over the years, one reason at least...
rant over....for now
