PlayScore 2 will observe repeats written into your music, but sometimes it is useful to be able to repeat a short section.  This can help if you are learning a piece and want to play a passage over and over again, perhaps slowly at first and then getting up to speed.

To set a loop.  Tap and hold on the first measure in the loop.  When the green brackets appear, drag your finger to the final measure.  The music between the brackets will go on repeating until you tap the pause key.  To remove the loop just tap somewhere outside.  While looping you can still change the tempo, and stop/restart play.
