Disklavier

Hi group,

What I`d really like to know is
can you fully take advantage of a Mark IV PRO`s extra features from a 
computer?
In other words can you program in step time a Mark IV PRO by inputing 
the extra MIDI data as well as the usual note on`s and velocity? is it 
feasable?

Also which other MIDI controllers does the XP format actually use and 
how?

info much appreciated,

thank you
robert.
