does any one know where I can find nwc files of all 32
Beethoven Piano Sonatas and Chopin Impromptus?
AFAIK, there are some of them on different sites, including... NWC sample files.
For the rest, you may find many of them in MIDI format.
If you want to *hear* them, it will be cheaper and better in audio format.
If you want to *read* them, it will be cheaper and quicker on commercial scores.
It can be done with NWC, but it takes some time, even though NWC is the quickest tool I know for such a work.
Unless there are people who, as Fred for the Magic Flute, or some for the Messiah project (http://www.noteworthysoftware.com/), or a japanese for the Salieri work, will have made all of them.
Which is not impossible. Passion leads life sometimes :)
