Which app is that?

I've been looking for a way to leave my music tub at home. I'll have to check out the Bluetooth pedal. I told a few people at Yamaha to make the lyric thing easier to sync to sequences and audio files within the motif/tyros sequencer. No luck yet but they came out with the Notestar App. Right idea but I want control over the technology.

I did see a few apps...
Live Trax Pro --- Lyrics and background tracks
OnSong --- chord charts and backing tracks geared towards worship leaders

Thanks in advance for the info,
Johnathan
