John, thanks for the reply, and I can follow you as far as making the leadsheet into a pdf file...after that you lose me, sorry, my technical skills are lacking. Will your method allow me to enter in all my files and have them be transposable on the iPad itself? Seems to me creating a pdf lead sheet will make it static, not transposable but maybe I am missing the essence of that you are suggesting. And also, if you have to make a pdf file of each and every lead sheet, that will take a LONG time, when the BIAB files already exist and should be readable by any computer or tablet.
