Can I buy any electronic drum bass pedal?

About a year ago I bought a Yamaha DTX Explorer electric kit. I have played it quite a bit and have enjoyed it...except the bass pedal. The bass pedal moves around a lot when I play and doesn't give me the ability to keep up with what I'm playing. I want to get a new pedal. Anyone know if I can use just any electric bass pedal or have any recommendations? Thanks for the help guys!
