No sound from some VST's while trying to play imported Finale midi trks

Perhaps the MIDI notes have a channel assigned, which can cause issues when trying to play with a soft synth that expects notes on channel 1 only.  Open the Event viewer and look at the MIDI data.  There may also be control messages that you might need to delete as well.  I see this a lot when using MIDI loops.
 
I fix the MIDI channel assigment using a CAL script AssignMIDIChannel.cal, though I'm not sure if it came with SONAR or if I collected it.
 

You can use the Process->Find/Change menu item to change things, but how to navigate its zillion options (on multiple dialogs that make it look like nothing happened the first time unless you notice the slight change in the title of the window) is so painful I'd rather not try and explain it to anyone, ever.
 
Here's AssignMIDIChannel.cal.
 
 

(do
  (include "need20.cal")
  (int new_chan 1)
  (int i 0 )
  (getInt new_chan "New Midi Channel: " 1 16 )
  (-= new_chan 1 )
  (forEachEvent
     (do
         (= Event.Chan new_chan )
         (++ i)
     )
   )
   (pause "Adjusted " i " channel events. ")
)

Thanks (Matt, savoy, scook) for the replies. I have used the Find/Change (Event Filter) in SONAR in the past and had already looked at the channels (which I did change back to Ch 1) and had used the Event List to scrutinize the midi data for any out of the ordinary control data and did not find (except for different channel numbers) anything that would contribute to the issue.
 
I then changed the VST property to select "Do Not intercept NRPNs" to no avail. I then went back to Finale to see if I could affect how midi data gets exported and didn't see anything that would allow me to just export midi note and CC data BUT that got me thinking about the midi file type options (Format 1 -all instruments saved to separate tracks or Format 0 -all instruments saved to a single track. I always normally use Format 1 so I tried switching to Format 0 and that seems to have fixed it.
 
Odd that when I do the import back into SONAR the Format 0 Finale midi file (a piano part consisting of a single grand staff) still loads into two separate SONAR midi tracks (I thought the midi file would load into a single SONAR trk) But, the D-Pro vst does play back ;-)  
 
Thanks again for everyone's input...

Thanks for the midi type link - that helps and I agree, still not sure why type 0 works and type 1 doesn't but at least I can still import from Finale which will save time re-recording the same parts in SONAR.
