In this post we examine the resonator section of our physical modelling instrument Derailer. The plugin uses mathematical models of three basic elements; stiff strings, metal bars, and nonlinear springs. The resonator uses the metal bars which can be connected together using the nonlinear springs. There are five bars and up to ten springs that …

In this post we will look at the driver section of our physical modelling instrument Derailer. The plugin uses mathematical models of three basic elements; stiff strings, metal bars, and nonlinear springs. Details can be found in this technical paper. The driver section uses the stiff string element which can be plucked or bowed, alongside effects units such as a low-pass filter. The signal chain is shown in the diagram above, with the output of the driver section being used as the forcing input to one of the metal bars of the resonator.

We have released all new versions of our physical modelling instrument Derailer, and our Spring and Plate reverbs. These now support both macOS with AU, VST3 and AAX plugins, and Windows 10 with VST3 and AAX. Derailer has been redesigned to incorporate a driver/resonator setup, expanding the range of elements to include plucked or bowed …
