IOLabs has a Eurorack module available via Kickstarter that allows you to setup simulations of physical motion ( think of billiard balls on a magic billiard table ) and interprets that motion as you would like into rhythm and pitch expressed in CV, and maybe MIDI data too.
It is called Particles.
The module included a touch sensitive color display for control.
The project is already funded but is still open to join.
This video shows only one way to set up the “physics” in your simulation world. Many other ways of interaction can be created, as well as how that all gets interpreted. Read more about that at the KS link.
£419 or about $532 USD.
IOLabs also makes another Eurorack module for generation of complex rhythms called Flux.
