Larry, I use all my charts in PDF, I think its become the "de facto" standard now.

All I do is either print from my PDF Fake Books if I want to use dots, or create my own chart using just a chord prog and prompt lyrics, I then use one of the "Print To PDF" programs and bingo there is my PDF file ready for transferring to the iPad.

Or your source file can be anything. Word .doc, or a txt, or a bmp or jpg... I have used all of em to get the charts I need/want. They all come out pretty much the same, although the files based on images are not quite as "crisp". Although that said, I don't spend too much time worrying about the initial res either

I use an app called UnrealBook (I was using Music Reader) but UB is far easier to use on stage and it now has MIDI support (control file only) it will also allow the user to link an MP3 backing track to a chart, so th instant you pull up the chart the MP3 is also loaded nand ready to go!! Pretty Cool!

I also use the AirTurn Bluetooth footswitch, for those few tunes that do have multiple pages. Works well, and Unrealbook already has built-in support for it.
