That "Canned" music sound

I spent years using Noteworthy Composer, before moving on to Music Creator.  Several years ago I finally moved up to Sonar.  It is fun growing and learning, good luck and enjoy!
 
A big problem you are hitting is that computers play perfect everytime.  The tempo is always going to be perfect.  Every note is going to be perfectly on the beat.  Every note fired is going to play a replica of the same sound.  Every note is going to have the exact same volume.
 
If you want that song to sound more human, it has to be less perfect.  Insert tempo changes at different phrases or even at significant measures.  For example the exciting finale may play the tempo at 5 bpm faster than the average song tempo, with the last measure of the finale playing 8 bpm faster.  Change the sound played in some small way for different parts of the song.  Examples are changing the velocity, chorus, or reverb of sections of the song.  The more you tweak the song, alway the way down to individual notes, the more human it will sound. 
 
Everything I mentioned in the previous paragraph are controlled by MIDI commands, so the changes should be able to be controlled in Noteworthy.  As I said it has been a long time since I used Noteworthy, so I don't remember exactly how to do it.  I do remember using the dynamics alot to change the volume for sections of the song.
 
Another problem may be the soft synths sounding a little too fake.  It is great if you can afford to go out and buy the exact collection you want.  My choice years ago was that I can't reproduce sounds that replicated 'real' instrustments so just go with the flow and create awesome synthetic sounds. 
 
I did and still frequently layer soft synths by playing copies of the same MIDI track through different soft synths.  You may have to alter the tune of the instrustment or transpose the notes so the individual soft synths have a closer matching pitch.  A good combination not only provides a cool new sound, but also frequently provides a fuller sound.
