Xylophone and Bass Marimba are similar to the vibraphone but are using wooden bars instead of aluminium. Each bar that vibrates when hit with mallets is paired with a metallic resonator which is tuned to amplify the sound.The Pianoteq virtual copies of these two instruments are respectively modelled after a modern 3½-octave French brand xylophone and a modern 5-octave French brand bass marimba. Thanks to the sophisticated Pianoteq physical model they come in several variants and benefit from the recently developed humanization feature which allows varying the strike point adding to the musicians interpretation a vivid and stunning realism.
