Diki, 
i own a Casio CZ1000 too my friend
BTW, i do customize my styles to be my own, 
i use my OWN Audio Drums on many of my own styles for Portuguese and Brasilian music
and hopefully soon,  i will be adding my OWN Audio Guitars,  Ukulele loops, (fingers crossed)
and yes, i will include TONS of chords, ALL in Audio, 
including 7th, M7, 6th, 9th, 11th,  Dim, Aug, Sus, 
the sky is the limit, IF you are open-minded and take the time   

keep on rockin' with the G-70,  it is a fabulous board as well no doubt.
