The HarpTime synthesizer was designed to reproduce the sound of the plucked folk harp, and uses an advanced physical modeling synthesis in which twelve strings are all individually modeled to allow true sympathetic resonances. The harp has a beautiful sound which is usable in very many musical styles (mediaeval period music, classical, folk, ambient, film music and ballads, for example). However, samples can only reproduce a limited, and somewhat 'static' snapshot of a particular real instrument being played. In comparison, physical modeling allowed us to build a VSTi which reproduces the characteristic of a variety of real harps, with more flexibility, control, and dynamics than a sample set will normally provide. HarpTime can reproduce the beautiful of the Celtic harp, as well as that of many similar types, such as Japanese (koto), Paraguayan and African harps.
