BandMaster 1.5 iPhone edition as well as iPad edition add support for song libraries. These additional modules allow access to over 1100 Jazz standards (Songs_2 and Songs_3 will become available shortly for the iPad version). The chords menu has been extended to include many less common chord choices and has been rearranged using somewhat more logical groupings. Playback of songs has been optimized in this version and several cosmetic glitches have been addressed as well. This upgrade is free and recommended to all users.
