Grate Piano Guitar Pick

Grate Piano is a virtual instrument for Native Instruments Kontakt giving you scratchy piano sounds. For Grate Piano the lowest 30 notes of a Korean upright piano were played with a 1.14 mm guitar pick by scratch­ing along the strings (only the first 30 strings on an upright have a copper-wrapped surface).

By its nature Grate Piano is a great tool for horror and ambient sounds or sound design.
