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.

Matt at a podium with a projected title slide behind him, presenting at DAFx conference

Great to have the opportunity to present a paper by @francisco-bernardo.bsky.social, myself, and @apmcpherson.bsky.social at DAFx 2025: "Impedance Synthesis for Hybrid Analog-Digital Audio effects". The work, led by Francisco, integrates digital systems into analog circuits bidirectionally.

The HaptiCoupler demo setup with two HaptiCoupler kits - one standalone and one connected to a host computer, along with an information poster

Great to have demoed the HaptiCoupler kit at #lac2025 yesterday. Lots of great insight and creative ideas from people trying it out. This kit is open source, find all the files (firmware, schematics, PCBs etc.) in the GitHub repo here: github.com/davisonaudio...

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!

A poster briefly describing the HaptiCoupler kit. The kit uses a Teensy 4.0 and a MAX98389 class D amplifier along with a voice coil transducer.

(2/2) Find out more about the kit at the GitHub repo here: github.com/davisonaudio.... Get in touch if you want to borrow a kit to experiment with!

(1/2) I'll be presenting a demo of the HaptiCoupler device at the Linux Audio Conference in Lyon this week! ( jimlac25.inria.fr ) The HaptiCoupler is an open source kit that enables bidirectional tactile interaction with digital resonant synthesis instruments
