Hard to find a classic Zepplin tune featuring a piano. Here's one using two Casio's. The tone is a concert piano from the PX150 Privia. The phrase sequencer in the XWP1 makes playing this song so much easier to play.
I play the solo once and simply by pressing the sustain pedal, the XWP1 takes over the monotonous piano part, allowing me to real time play the trap percussion and marimba part. Thanks to Mainstage2 I'm able to layer the last two octaves of the PX150 seven times.  That allows me to play live what it would take three people to do. All playing the same exact piano part simultaneously, each in a different octave .
