Synthesizers with unweighted keyboards

Unweighted

— keys with almost no resistance when pressed with a finger. This is the simplest option, used mainly in models with passive mechanics, extremely rarely with active ones (see "Keys"). Perhaps the only advantage of unweighted keys is their low cost; at the same time, they do not give an adequate response when playing and are suitable mainly for the simplest parts, or for working with timbres designed for the same volume of each note.
