Hi Peter,
Im currently building a battery bluetooth midi playback controller for stage traxx 3 with an arduino. With the upcoming sysex support could you add a way that when the song is selected as the current song it can send a sysex message of the title of the track. Would be useful for LCD screens to see the current track, especially when scrolling through a setlist. My drummer could see the songs on the screen then select one and play it, without being near the ipad.
Love your work brother!
