Thank you. I don't want to create songs or edit songs on the iPad. I'm performing as a singer and guitar player "on stage" with relatively simple basic Biab comping tracks in the background that I have created on my MacBook Pro. Instead of using my MacBook for the playback "on stage" I'd like to use my iPad as a Player allowing me to see the cursor wandering through the chords whilst it is playing back the songs I created on the iPad, so that I can follow where it is in the song. What do you mean with "freezing" a song?
