Physical modelling system

Derailer is a physical modelling system built from 3 basic elements. Strings which can be plucked or bowed, metal bars which can be pitched or act as resonators, and nonlinear springs which can be used to connect resonators together to form a network. Derailer uses finite-difference time-domain numerical modelling of these elements, as detailed in this technical paper.

Driver

Derailer uses a driver and resonator setup to provide a flexible system with a wide range of sounds. The excitation signal can be a sawtooth waveform, a plucked or bowed string, a pitched bar, or a striker. This thens passes through an EQ section and low-pass resonant filter, a diode clipper, and then a delay or gate. The resulting signal is then used to drive one of the bars of the resonator network. See this post for further details.

Resonator

The resonator is built from 5 metal bars which can be connected together by up to 10 nonlinear springs. The spring positions can be moved around to change the resonance of the network. Each bar has controls for rigidity, sustain, tone, and mass. Each spring has variable stiffness, decay and nonlinearity.  See this post for further details.

Demo tracks by Dara Etefaghi

Dara is an audio-visual artist and developer based in Edinburgh. His work is focused on 3D real-time sound and graphics. He creates nonlinear game-like compositions that explore themes such as chaos, silence, dissonance, altered states, Human Computer Interaction and other intersections of culture and technology. He aims to blur the boundaries between contemporary audio-visual art and video games by creating game-like performance systems. These tracks were created using multi-tracked presets from Derailer, with minimal post-processing.

Presets by Deru

Deru is Benjamin Wynn, an award winning electronic musician and composer based out of Los Angeles. He has been releasing albums and scores under the Deru alias for the last 15 years.

In addition to his own music, Wynn composes for television, film, and dance, and creates multimedia performance experiences as part of The Echo Society.

Derailer Quad

Derailer Quad is a special version specifically for use with 4-channel audio systems. Each resonator has its left and right output assigned to pairs of channels as shown here, giving an immersive sound environment. See this post for further details. Derailer Quad uses the standard Derailer licence.
