Brand new project was playing back thru my Roland Quad.  Then shut down and reboot and now Sonar meters are outputting, but the Quad is not receiving signal and not sending to my speakers.  Separte projects do not come out the speakers.  Any idea what happened to my signal?

Strange.
Is the configuration of the Quad still valid in Sonar ?
Are the Asio Parameters the same in Sonar and in the Quad Capture control panel ?
 
Something general you can try after having restarted Windows & checked your drive: delete all temporary files and folders*. Then start Sonar.
 
* Windows + R keys. Enter %tmp% in field open then click ok. Check that you are in the temp folder, select all, delete all. Note: It may well be that you can't delete everything, that's ok, some temp files are opened.
 

The two Knobs for output and playback in the right position?
Checked with a headphone?
USB LED shines green?
 

I have had this same problem with 2 Studio-Captures. If you are using the ASIO driver, sometimes Sonar will crash the driver. Especially, after using another audio program that is set to use the ASIO driver. DO NOT RE-BOOT!! It never worked for me. Choose to RE-START when you shutdown. It always brings back the ASIO driver. This has always worked for me.
