Hi,
You may be interested in Notation Composer. You can record live playing on any MIDI instrument (eg. keyboard), and it will transcribe your recording to sheet music. You can see the video at
http://www.notation.com/vb-forum/showthread.php?t=3649 for more information on "live" recording". We also have a number of other tutorial videos to help you get going. You can see the list and brief descriptions at

As always, if you have any questions, feel free to ask here. We have a lot of very helpful folks!
ttfn,
Sherry
