Development of a Synthesis Model Based on KS Algorithm for Metallic Percussion Instrument

Abstract

This paper describes a basic synthesis model based on the KS algorithm for metallic percussion instrument. Unlike other percussion instruments, Korean metallic percussion instrument called Jing have a precise harmonic structure that is characteristic of stringed instruments. In addition, each harmonic exhibits a frequency gliding phenomenon called softening according to the intensity of the deriving, and irregular non-linearity called hardening for some partials. Therefore, the proposed synthesis model applies KS algorithm for harmonic structure and KS algorithm with time-varying propagation speed for irregular nonlinearity, hardening.
