I transcribed The Oddity into ABC since I wanted to print it in 3/2 (without the 2/4 version cluttering things up). I realized it had quite a narrow range, so I got BarFly to transpose it and added it to my file of nine-notes-up-from-C tunes:

I think it would be more use to most of us if the site were just done in ABC from the ground up, since that would allow operations like transposition and editing the tunes into our own medleys. But it's your baby, and better you do it your way than not at all.

For a comparison - I think it took me about four hours to put that chalumeau tunes file together. I only transcribed one or two new tunes for it, but there was a fair bit of minor editing involved, and most of the tunes had to be transposed. How long would it take you to put together 50-something tunes into a tunebook using Sibelius, if you already had them in different files and in different keys?
