FTM String is a unique sound synthesis plugin developed as part of a student project led by Stefan Petrausch and programmed by Daniel Maaß. It brings advanced physical modeling techniques to practical use by simulating the behavior of oscillating strings based on mathematical solutions to partial differential equations. The core technology behind this plugin is the Functional Transformation Method (FTM), which allows for detailed and dynamic sound generation rooted in scientific research from the laboratory.

This plugin simulates an oscillating string that can be excited by plucking or striking at any point, offering a highly flexible sound source. Its general string model can emulate a wide range of one-dimensional vibrating objects, making it suitable for recreating sounds from various string instruments such as guitars, basses, and the cembalo, as well as percussive instruments like the xylophone, vibraphone, and chimes. The versatility comes from adjustable physical parameters that can be changed continuously and in real time, enabling users to craft diverse tonal characteristics.

Rather than focusing on exact replication of traditional instruments, FTM String emphasizes the adaptability and expressive potential of the synthesizer. By manipulating the physical properties of the modeled string, users can explore a broad palette of sounds that evolve naturally and respond intuitively to performance gestures. This approach showcases the strength of the Functional Transformation Method in creating flexible and responsive sound synthesis tailored to creative exploration.
