We demonstrate the idea by replacing the diodes in a Boss DS-1 distortion pedal with our synthetic impedance system, while keeping the rest of the system in the analog domain. This provides a proof of concept, but there's lots more exciting ideas to explore!

By measuring the voltage at a node and actuating a currently, any two port electrical component (or network of components) can be simulated digitally in an otherwise analog circuit. This presents a customisable electrical impedance to the circuit, which can be reactive, non-linear, etc.

It's a device designed for interacting with resonant synthesis models! It can either work standalone (synthesis running on the Teensy) or with a computer running the synthesis (USB audio connection). The device provides vibration feedback from the model as well as simultaneous tactile sensing!
