  I thought about this recently for both dynamic and pedal marks. I thought 4 
tracks (RH, LH, dynamics, pedal) on one channel would distribute all the 
changes. Either my midi knowledge is wrong or/and that couldn't work well 
about how a mark would be handled if it applied to only one line. I don't 
want to start hate mail and fired discussions, but better notational & midi 
knowledge is something I can always use so . . .
