deatonent,
Dave and Donny are all correct, but their method is a little slower and requires more button pressing in that you have to mute all the parts except your piano and the drums beside turning on the "pianist" button. I have an easier method:
Press the "pianist" button next to the master volume slider, and press the "Manual Bass" button right above the "pianist" button, and the two red LEDs of the buttons light up. Then mute the "Bass" by simultaneously pressing the two Bass part volume buttons. Now when you press "start" button, only the piano and the drums sound. Using this method you practically can do it in two touches, one touch for "pianist" and "Manual Bass" buttons, second touch for muting Bass.
Another style that I like very much on the X1 is having guitar (steel or classic) with or without strings as the right hand instruments, with bass for the left hand, and drums in the background. I also use Roland PK-5 pedal board to play sustained high pitch strings sound to make it a very effective small band. For this setting, you just have to undo the "pianist" button and unmute the bass part from the setup that I described last paragraph, and select your right hand instrument(s) - using a registration for this manual style makes it very easy.
Hope you enjoy it,
