Goods apps for this purpose:
- OnSong - import PDF files and use the auto scroll function for the lyrics/chord charts. You can also attach an .mp3 file to play while the chord chart scrolls.
- Set List Maker - similar app as above.

Look them up. I keep trying new things. All work pretty well. I could probably make any of them work but I just love trying the next new thing.

Later.
