Looks like MIDI-Ox is not compatible with W10. So looking for best options
LoopBe30 ???
Tobias Erichsen’s loopmidi ???
Any suggestions please

I had better luck with Tobias Erichsen’s software, but I would suggest trying both because you're dealing with drivers and system configurations vary. What works well on my system may not work on yours, and vice versa.
 
LoopBe1 is free: http://nerds.de/en/loopbe1.html
 
I haven't tried them since UWP MIDI was added to Sonar, so you might want to try that option with them, too.

Loopbe30 and loopbe1 both work flawlessly with win 10. The choice just depends on how many virtual cables you need.

I have no problem with loopMIDI. MIDI-Ox is working fine for me as well, but I use it for diagnostic only.

I run both loopbe30 and MidiOx in combination under Win10 with no problems.  I use most of Midiox features such as Translation Maps to convert controllers, NoteOn parameters, etc and Patch Maps to select those Translation Maps (depending on what Prog Change I send it from a midi keyboard).  Then the virtual midi output of that is received by Sonar tracks.

Thanks for the input everyone
loopBe1 will be all I need
