Available for download, the Modartt Celeste from Pianoteq is an add-on for Pianoteq 3.2 or later. It contains four instruments: the celesta, the glockenspiel, the kalimba, and the toy piano.
These instruments are often heard in contemporary classical music, horror film soundtracks, and talk-radio music beds, which always seem to include either a '90s-style hip hop beat or a wistful glockenspiel.
The celesta has an appearance of an acoustic upright piano, while the glockenspiel resembles a high-pitched xylophone. The toy piano is an instrument that also resembles an upright piano, but has its own quirky sound. The kalimba almost looks like a harp, except it's made out of a wooden board with metal tuned tines for the plucking.
Thanks to Pianoteq's physical modeling, these instruments offer variations, including a humanization feature for the strike point that makes each note more expressive. This option is particularly useful for the glockenspiel, as glock players never hit the plates at the exact same point. It is also possible to add features of traditional pianos, such as damping, sustain pedal, and soft pedal.
