I just upgraded to a Roland Studio Capture. The install seemed to go smoothly. I added a couple of tracks to an existing project just fine (with input monitoring!) but when I try to assign their output to a new bus the dropdown menu doesn't open and they are stuck on Studio Capture out 1 & 2. i then tried to change tracks that were previously recorded and routed to buses. They remained assigned to the proper buses but the dropdown menu didn't open on them either and I couldn't change them. Probably just a setting, but nothing jumped out at me in preferences so I figured I'd ask the geniuses!

Hmmm, worked after closing and reopening Sonar...

I don't know if I can help but I'll look at my system ... Studio Capture running Platinum x64 also.  If there's something you'd like me to try ... just ask ... as long as I don't think it'll put me the same situation.  My system has been extremely reliable ... so it would be a good baseline to see if you're doing something different that might stick out like a sore thumb ... and, that'd be good.  Let me know.

Sorry ... didn't see the "solved" note.

Thanks, Lick, yeah it was the old turn off turn on fix, lol. it was my first time firing up the Roland so it just took a minute for everyone to play friendly. I'll keep you in mind if I have in questions.
You're making my Martin D-15 feel lonely...
