That's the problem John. No music program or DAW can add anything to what you enter. All you can enter into Biab's notation is the notes. Yes, you can add some velocity by drawing curves with your mouse in the piano roll and that helps a little. You can draw in a fade at the end of some notes so they don't just cut off for example. But to do that for an entire 16 bar complex solo melody line? Man, you could be a week doing that.

I think a far better way would be to find complete midi files online that contain the melody that someone else already took the time to play live using a good midi controller. A controller has the sensors to capture your playing including velocity, modulation and all the other things that make a midi line sound real. If you want a sax playing the melody there are files where the sax player used a wind controller that plays like a sax and the DAW records all the nuances the controller puts out and that's what's in the midi file.

The problem is you may not be able to find commercial midi files of the songs you need and if you do find them you may have to pay for them. That could be worth it because they're usually not terribly expensive. They can be something like $6 or $7 each and they usually discount them if you buy 5 or 10 at a time. Many times you can find free ones too. But free is free and you get what you pay for. Some are pretty good, some not.
