Jack - think it comes down to familiarity with the program. It'd probably take me roughly the same amount of time to input the same tunes into Sibelius, which has an auto-transpose facility. I had a look at your link and it made about as much sense to me as my site probably does to someone who doesn't read notation! I mainly access music by ear and use notation as a second string. At the moment, I don't have time to get to grips with abc, I'm afraid, but I'll definitely bear it in mind as a future project when I'm less frantically busy. :-)

Will - I think I'm going to try and go with the Scorch idea. That way it doesn't cost anyone (including me!) anything to access the tunes and people who are unfamiliar with notation can hear as well as see them. If there's loads of interest in the site a few weeks down the line, I'd be tempted to pay for the upgrade and add the files as MIDI as well, which can presumably then be imported into a variety of music software (I know my friend's copy of Mozart imports MIDI and displays it as notation and tab.)

Thanks for the feedback fellas!
