Disklavier

First of all, I don't have a Disklavier, but am seriously 
considering purchaseing a DC3A.  If I record something, how do I 
transfer the data to my PC which is running Sonar 2.2?  Does this 
come across as a standard midi file?  Can I correct some of my 
performance data (ie. note mistakes, etc.) and then play it back on 
the Disklavier?  Do I lose any performance/key/hammer/pedal 
information when I make a midi file out of it?   I am referring to 
the piano in ANALOG mode (not playing the digital piano tones, but 
the disklavier actually playing the notes/keys/etc.).  Thanks!  SJ
