MPE Sound Design in Surge XT: Physical Modeling Demystified

In this episode we introduce physical modeling synthesis using the Karplus-Strong aglorithm. After a bit of theoretical talk we'll use a comb filter as a resonator and explore a number of ways to shape noise and other sounds to serve as the exciter. We will focus on plucked sounds today; there was too much material to fit into a single episode, so next time we will explore bowed strings and inharmonic resonance, here:    • MPE Sound Design in Surge XT: Physica...
