hi rikki,
the idea would be to play the ivory from the laptop, not load it into the SD, via midi..quite east to do with the right host, forte for example is one that comes to mind..also all the big DAW sequencers can also host vsti's and dxi's...just switch on the transmit channel of whichever keyboard channel you want to drive it...

PS i am also thinking of adding one of the great electric guitar vsti's as well...you could even set it up so that one, or more of the arranger tracks can also play the vsti too...the possibilities are endless (oops! should say almost endless)
