That's what I thought you might want to do, that's why I suggested using Realband, it should work fine just using the SEQ file on the tablet.
Edit: also in RB you can just have one track that has the music (mixdown of the multitracks) so the SEQ will be only about 30meg.

You can have full screen chord window:
