Ugh, not in my DAW by now, Vice...
But here's the quick hints
In the begining of the song, SONAR will send particular MIDI controller message shown in the track view (Vol, Pan, etc). The value you inserted will be sent as initial value when the song is being played from the start (very first measure). So, if you insert realtime controller message (eg. CC 07 for Volume) in the middle of the song, it still will change the value realtime as the song rolling.
Try this...
New MIDI track --> Volume = 100 (Enable Control)
insert some notes for couple measures.
Insert controller 07 value = 60 somewhere in the middle of the song.
Play the song, you'll noticed the volume will decrease in the middle of the song as it hit the controller message. Let it roll to the end.
Rewind, start the song again... The volume will be initialized to 100.
Now dissable Control... Do the same step... play the song, volume will decrease in the same spot... let it roll to the end... and rewind... play it again... The volume will remain 60... not initialized to 100
Got the idea...
Good.

I'll be back if you need more explanation about it latter... (I'm hurry now
