GEMS App app for iPhone and iPad

GEMS is an app for graphic edition in music scores, designed for education and performing situations. This application allows communication and synchronization of several devices (in a master/slave correlation) between musicians or teachers/students sharing data by a wi-fi net.
In the Editor Mode you can mark colour areas in different layers.
In the Player Mode, any music .xml file can be a single row scrolling in your screen.
This is the first version and must have critical upgrades, and was developed for professors and students from PUCPR, Pontificia Universidade Católica do Paraná, Brazil by the BEPiD (Brazilian Education Program for iOS Development) program.
GEMS is an innovative way of sharing music scores for performing and educational purposes.
