Yes, Joe...if I remember correctly, it's the master keyboard midi out to the Tyros4 midi in and set Function MIDI to "Keyboard&Style"...if I want full piano I just turn off the left and style (acmp) on the Tyros4. The P-95/P-85 I sometimes use as a master/controller, transmits on midi channel 1 by default.
