Here is what I would do. Figure out the notes on your guitar. You don't necessarily need all the notes just the starting and ending notes of one piano rip. In the piano roll view of the MIDI piano track input those notes. Now fill in the rip with the in between notes; this may take a little time. Once you have one part down you can copy, paste, and transpose the part to fit the other chords.

This maybe easier in a DAW with a higher PPQ.

Good luck.
