karaoke file with music notation not lyrics possible?

[ezjazz]

Thanks for your reply.

At the moment I use notation to change keys and print melody lines from midi files. I then use a korg module to play the backings and i play the printed melody using the bar counter on the module as a guide thru the track.

I edit the midi files with another software.

What I would like to be able to do is to use a tablet eg ipad,nexus to replace both the module and the printed music.

I dont know if this is possible but i thought that using karaoke as an example as it is an audio track with lyrics, was it possible to have an audio track with music notation?
