The physmism is the result of the Master thesis of Steven Gelineck and Niels Boettcher.
In this project a physical interface was created to explore the possibilities for improving the creative use of physical modelling sound synthesis. A set of possible factors for improving the creative use of physical modelling were proposed and a novel interface for controlling physical models, the PHYSMISM, was designed and implemented. The PHYSMISM was implemented in a software and hardware version. Moreover, four different physical modelling techniques were implemented, to explore the implications of using such techniques.
Here is a paper about the PHYSMISM.
