Synth Action

A type of keyboard action, Synth Action keyboards are typically constructed of plastic keys and use springs, rather than weights, to return the key to its initial position. Synth Action keyboards produce a quicker and lighter feel than weighted keyboards, and they work well for certain types of music and for playing the sounds of instruments other than the piano (which many digital pianos have). Many straight-up synth musicians prefer the feel and playability of a synth action keyboard over a more expensive hammer-weighted action for these reasons.
