Not able to record MIDI in Sonar 8.5. HELP !!!

Hi,
 
I've been using Cakewalk/Sonar for over a decade. I never ran into problem like this before and it just makes me soooo frustrated and mad. I installed Sonar 8.5 and used USB midi controller to record midi. Everything was fine. Now I bought AVID M Box. After installation I connected my favorite midi controller  Roland A-30 through AVID midi IN and I can't record any midi notes. Yes , Sonar recognizes the Avid MIDI devices and they are selected. Also, in midi track i have selected input - MIDI Omni. When I record a MIDI track only some patch changes are recorded. No notes. The funny thing is that the MIDI works --  since I can record midi into other applications such as Sibelius or Cantabile performer. What am I missing here ???

have a little bit of patience.  10 minutes and you're paniking because no one has responded?

when you say your input to your MIDI tracks is "MIDI OMNI" that is a concern - it should be OMNI AVID or something similar.  you may have more than one MIDI input device selected. 

so - what ARE your MIDI input devices in OPTIONS>MIDI DEVICES?

well that sounds OK then.  and if you're getting full MIDI in Sibelius using the same hardware setup but only some patch changes in sonar then I'm not sure what would cause that.

I can only suggest downloading and installing MIDIOX and you can use it real time to monitor what MIDI messages are being read by the avid box.

Update: MIDIOX is recording notes being picked up by mbox. so midi in is fine. the issue is within a sonar i guess!!!

I have no idea what has happened but by miracle, now i finally can record midi notes !!! YES !!, now i need to how to monitor vst instruments. I can hear it only when I press play or record. Any suggestions? (  I feel dumber and dumber ) :)

Thank You, Thank YOU , THANK YOU! Problems solved !!! (still no idea how ) :)
