I just bought a PX-160BK and did a little, but not enough, research on portable triple pedals for the keyboard. Casio's SP 33 is clearly not portable, but the keyboard is compatible with it, meaning it will work with a triple pedal. M-Audio won't tell me if their SP-Triple is compatible with my keyboard and I have not heard back from Studio Logic regarding their VFP-3-10. Has anyone had any success using either of these or another triple-pedal using either a PX-160 or another of Casio's keyboards compatible with the SP 33? Thanks.
