This paper summarizes our recent achievements in developing signal processing methods for model-based synthesis of plucked-string instruments. The methods discussed are applicable to a broad family of musical instruments, but this paper concentrates on a case study where we focus on the classical guitar. The real-time guitar synthesis engine is based on digital waveguide modeling and commuted waveguide synthesis. The paper provides an overview of our Lisp-based real-time synthesizer and how it is controlled. Furthermore, extended procedures to synthesize transients, pizzicati, and improved dynamics are presented.
