Just to clarify - during the week I am away from home, and my time online is limited to a slot at the Internet Cafe at work. The machine is well locked down, and allows very little to be done. Only IE and hotmail are possible!

The good news is that I have plenty of development time in the evenings on my laptop.

Ed:
HARMONY is a 'Tune Processor' which is mainly intended to take a melody and add value to it.

For example, add chords, add harmony voices, turn a tune into a round, turn a reel into a hornpipe, add effects, add lyrics, make it into a Karaoke file, and so on.

(There are plenty of other programs which just let you type a tune in and then print or play it.)

The import and export are obviously needed to get tunes in and out. The score display is needed to see and edit the tune. Printing is an extra, but not the main purpose.
