The XPK-130G by Hammond is a MIDI bass pedal with 13 keys and integrated tone generation. The virtual analogue sound generation is monophonic and has five sounds: Electric Organ, Pipe Organ, Synthesizer Bass, Fingered Bass, and Upright Bass. To adjust the sounds to your own taste, there are cutoff and release parameters. Since the pedal sends and receives MIDI notes, it can be used as a sound expander and as a bass octave for other MIDI sound generators. The XPK-130G is aimed at piano players, keyboardists, guitarists and other musicians who value bass accompaniment via foot control.
