just accuracy, opinions and comments describing well this pedal, it is not reserved only for M-Audio ... I use both on my M-Audio keyboard than on my master keyboard and piano Casio E-Mu & Korg synths ... Very solid and reliable, having tired of the change from one keyboard to the another, I just bought (eyes closed) and in a second ... well buy two additional) So to me this is a sign that this is a very good product that has nothing to do with small ridiculous plastic flat pedals sold with some synths .... I own the first for 6 years and have never had any problems with that fear .. say that?
