Simply plug it in, connect it to your keyboard via MIDI, and you're ready to enhance your playing with sound effects and bass lines provided by your feet, leaving your hands free to play melody and accompaniment. When used in conjunction with Hammond's XK-2 and XB-1 drawbar keyboards, the XPK-100 allows you to create a virtual B-3. In addition to a MIDI out port, the XPK-100 pedal board features 2 separate MIDI in ports, thus allowing the easy use of 2 MIDI keyboards -- an ideal twin manual MIDI system. Ideal for use with the Hammond XM-1 drawbar module and the XB-1 and XK-2 drawbar keyboards. Also suitable for use with many MIDI-compatible digital pianos.
