Somehow I've never been able to learn to write down the tunes to songs I've written, and it's a bit late to do so now. But I'd really like to be able to put them down in staff notation.

There are a number of apps for ipad which claim to be able to help, so I'm hoping maybe someone out there can advise me what to try using.

What I want is to be able to play a simple melody line into my ipad mike with a guitar and get a staff notation of the tune Incan print. No worry about sticking in chords or harmonies, I can sort that myself.

If anyone can help I'll be very grateful. And if possible as soon as possible - I've got a deadline for a choir.
