Abstract
A physical model has been developed for real-time sound
synthesis of the Clavinet, an electromechanical keyboard
instrument from the 20th century. The Clavinet has a peculiar
excitation mechanism, relying on a tangent striking
the string. The modeling paradigm chosen is waveguide
synthesis and this paper suggests several novel techniques,
such as a polynomial excitation pulse model and a beating
generator, both of which have parameters depending
on key velocity. Realistic emulation of the release part
of Clavinet tones is based on a decrease in the decay rate
of the tone and lengthening of a delay line, which corresponds
to the physical string. A real-time implementation
on Pure Data demonstrates the efficiency of proposed
model.
