Page turn for piaScore
PiaScore is a score app for musicians. A page turn function with flic would be great.

If you are on iOS, you can use Flic to turn pages in iBooks, so if you can export your scores to PDF you should be able to do this! The iBooks action might work with other apps too, if they listen to the "next" and "previous" key commands. Hope this helps!
