Sonar Artist Midi Routing issue

I am having midi routing issues.  Sonar Artist. Older Yamaha S90. Fastlane USB hardware midi interface. S90 set to Local Control Off.  In and Out are both set to Port A in Sonar Midi setup.   Sonar recognizes the Fastlane and the S90 instrument definitions.   I can get 2-4 midi tracks recorded and playing correctly to the selected instrument patches. Then when I add the next midi track whatever patch I select is now also switching patch to, and playing from, midi track 1.  I have tried each individual midi input assigned to individual midi channels. I have tried all inputs set to "none". I have tried all to "Omni All".  In addition, in these other various choices, I get other bad behaviors like no auto patch through, or confused patch through.  Any help is GREATLY appreciated.
