Les, I have Noteworthy, and it doesn't offer the chance to convert to PDF. At least, my version doesn't.   I can save as a Noteworthy file or a MIDI file.

Upthread, a guest asked, "why convert it to pdf only for someone to have to convert it back?"

Answer: Yes, anybody can look at a pdf and play it. But if I put the tune into a music format (I use MIDI), I can do musical things to it. For example, I can change the key, change the clef, change the timing, write new parts...

No other kind of program permits these things. And I do them regularly for my church music and for music with my friends. For example, I often change music from the recorder-friendly of F to the
guitar-friendly key of G. The flutes appreciate that too.
