does anyone know if these boards read yamaha .sty files? and is it possible to alter the voice assignments (ie, change the drum kit) once they're loaded into the keyboard? I remember the MM6 didn't allow for any changing of voices/kits, which makes me think the newer psr's will have the same or similar architecture...
thanks in advance for any help! played the E413 the other day and was surprised by it. if it's possible to load in styles (via USB cable it seems, not, alas, a stick drive) and then "tweak" them a bit, this might solve a problem or two for me.
thanks
