Find all the details (including schematic, audio examples, etc) in the paper here: dafx25.dii.univpm.it/wp-content/u...

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.

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.

NIME 2026 is coming to London! 23-26 June 2026. General chairs Courtney Reed (Loughborough University London, Augmented Instruments Lab alum) and me. More details soon!

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!

(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

PhD opportunity: I'm recruiting a PhD student in digital musical instrument design at Imperial College London. Applications now, start date in the autumn. Funding is limited to UK home students. More topic details to follow. Interested? Email me with a CV! [email protected]

First Bsky post, first lab paper of 2025! "On mapping as a technoscientific practice in digital musical instruments" -- a dive on the history and critical implications of mapping theory, with speculation on possible futures. Forthcoming in JNMR: instrumentslab.org/data/andrew/...
