M-Audio Sp-1 : misterX's user review
« Works fine ... but it's noisy! »
I have used this pedal with plenty of keyboards of different brands and have never had a problem to make it work. The only downside is that the mechanism is noisy: Every time you press the pedal you hear a loud "clack." It's not a problem if you play at high volumes (when you play with monitors, for example), but when you play at home at moderate volumes, it's annoying.
