Effects can significantly change a sound or a whole groove. The same pattern can be made to sound very different when an effect is applied. The MC-505 has 3 separate effects processors that can be assigned to any Part or rhythm instrument. These effects are an important part of creating an interesting and satisfying pattern or song. The effects in the MC-505 include:
