Diki,
Of course we haven't seen the details yet..but it just might be time for you to look at Korg again. (Dont know if they will go with more than 2 fills or not, but with the new parms...it isn't that bad with 2). You can use PADS for fill as well and they are synced to the style. Very easy to program your own as fills.

If Yamaha does not want our business..screw them...we will go elsewhere.
It might happen more than they may think!
