This is all out there in hyperspace, but what about having external controllers mapped to attributes like PIT in PREVIEW PERFORM? I already love it and was previously tweaking the PIT on complete rows to get similar results. Its great but it(or i) gets a bit anal with the encoder..
2up, 2up, 3up, 5down, 2down, hold 1 bar
repeat 4 times
down 2, up1 up1
repeat 4 times
you follow?
ribbon controllers, wii-motes, distance sensors..
