Physical modelling synthesis

Physical modelling synthesis refers to sound synthesis methods in which the waveform of the sound to be generated is computed using a mathematical model, a set of equations and algorithms to simulate a physical source of sound, usually a musical instrument.

Modelling attempts to replicate laws of physics that govern sound production, and will typically have several parameters, some of which are constants that describe the physical materials and dimensions of the instrument, while others are time-dependent functions describing the player’s interaction with the instrument, such as plucking a string, or covering toneholes.

For example, to model the sound of a┬ádrum, there would be a mathematical model of how striking the drumhead injects energy into a two-dimensional membrane. Incorporating this, a larger model would simulate the properties of the membrane (mass density, stiffness, etc.), its coupling with the resonance of the cylindrical body of the drum, and the conditions at its boundaries (a rigid termination to the drum’s body), describing its movement over time and thus its generation of sound.

The Nord Modular range approximates the much more flexible world of modular synthesizers, offering an almost unlimited variation of synth architectures, with the facility to simulate, in addition to subtractive synthesis, additive, FM, and, in the second generation of the series, physical modelling synthesis methods, as well as a number of other sound generation and processing techniques. Unlike most other analogue modelling synth hardware, which generally simulate one or a small number of (usually subtractive ) synth circuit layouts.

The Clavia Nord Modular series is a line of synthesizers produced by Clavia, a Swedish digital synthesizer manufacturer. The Nord Modular series, in common with their sister range the Nord Lead series, are analogue modelling synthesizers, producing sounds which approximate those produced by conventional analogue synths by using DSP chips to digitally model analogue circuitry.
