Sorry Mate, it's got me stumped!
I tried opening one of my Noteworthy music files with various Players, no luck.
They don't recognise the file type, (it's a Midi file type).
So you cannot send, or use it as a Wave File!
All I can suggest that the recipient also has a copy of Noteworthy on his PC who can then either play your music file through his sound card, or send the Midi data to his keyboard from his PC.
Your music files will be compatible with everyone who has a copy of Noteworthy.
This is probably to only allow the music to be played by another Noteworthy user!
LAGO's Flight Sim Scenery Enhancer works in a similar way. Every user has to purchase the program to allow file exchange..!
Try putting your query on the Noteworthy Forum.
Cheers...!
