during our computer troubles, we lost a file in Noteworthy...when I went looking for fixes, I found this page of Noteworthy add-ons and music filesalso, while looking, found a link to AutoScore , a program which says you can sing or play into a mic, and it will produce a midi! (which you can then import to Noteworthy...and edit...and...well,you all get the idea)[not a cheap program, but if it works, might be very useful for some!]
