Over the last several years, I’ve been scanning music that I use and saving it in a folder that’s easily accessible on my desktop. I name the songs using the same format, so I can tell what arrangement it is. (I always make sure that I keep originals from the publisher to remain legal and to rescan if something goes wrong with the file.) If the music in Finale or Sibelius, when I print them I print a copy to PDF using Nitro PDF and save it in the same folder. Dropbox is a great cloud-based system where you can save all this PDF music to have at your fingertips, even if you’re away from your computer.
I’ve been using the Apple iPad for a while now and love using it on the bima. Since the vast majority of the music is scanned, good iPad apps can collate music very easily. I have tried ForScore and DeepDish GigBook. They are both available in the App Store for less than $8 each. I found GigBook was most efficient for my uses at temple, since it allows the user to send an entire setlist of music as a file to another GigBook user, thus eliminating sending individual pieces of music.
The temple band that I work with uses iPads for their music and they integrate a bluetooth page turner pedal. Using the footswitch, swiping and turning is no longer necessary.
