This is my first attempt with physical modelling. The instrument is based on an equation for the Brownian motion of a particle in a potential devised by Paul Langevin. You can find the files, presets and a short demo here: [https://drive.google.com/file/d/1xrKeS7quoXfKlG91N0ZRBb2ZIiN\_gCWX/view?usp=sharing](https://drive.google.com/file/d/1xrKeS7quoXfKlG91N0ZRBb2ZIiN_gCWX/view?usp=sharing).

Some really nice sounds here. This approach to physical modelling is new to me. I must take a deeper look into some time. 👍 ---

WOW. These are very inspiring instruments, documentation, and sounds! Beautiful work. Thanks for sharing. WOW. I checked out all your recipies too - nice nice nice. ---

Thank you for the kind words. I am a physicist by training, and for the instruments I usually draw from some concepts or methods in physics. With the documentation I want to makes this background clear. I also hope that some people out there can use this to write their own instruments. And often documentation also helps me not to lose focus when development of an instrument stretches over a long time.
