Tony, I don't know the answer to your specific question. Surely someone on the forum has the answer. Alec?

As we talked about before, I use a small four octave Novation midi controller, that just plugs into my computer USB port, to do notation work. (I know the 6000 has no USB capability)

I looked at the Notation Composer web site. Liked what I saw. If you choose to play the song directly into the software, there will be a lot of editing needed. I didn't see a quantize function but surely it is there. You will need that. In the past when I started from scratch, I usually found that entering the notes in a step function worked best for me, rather than recording as I played a song. Good luck.
