I want be able to edit/change chords on PDF lead sheets such as the songs in Real Books, Colorado Cookbook, etc. The only way I'm able to do so on my Android tablet is with my finger (extremely difficult). How can I make editing easier? The only editing of PDF files possible in Fakebook Pro is "painting" on top of the image described in the file. This is due to the nature of the PDF format, but most importantly because the books you mention (as well as most other similar music collections) are actually paper scans. That being said, you can simplify and increase the precision of your edits by using a stylus suitable for your tablet, and by zooming in on the part before editing. I do have iReal Pro on my mac (chords). What I miss is to also see the melody, together with the chords, both in a transposable fashion (which iReal Pro provides, but it's without the melody). Does your Fakebook Pro provide that, or do you have another offer or hint where to buy somet...
