Digital modules from Mutable Instruments (and related clones + offshoots) use audio-based data transfer for firmware updates.

Interesting way to give the consumer the ability to change the firmware without having to access the back of the module (there's a way to use a serial JTAG adapter as well).

Hey ericlewis - this is cool! Can I ask how you figured it out?! Doing this for my PO-33 was on my bucket list. I thought I might have to resort to voltage glitching to get a firmware dump, which is currently beyond my skills.

This reminded me of when people used to transfer games over the radio: https://www.racunalniski-muzej.si/en/40-years-later-a-game-f...

I didn't think I'd see something on the PD squad before I saw it on HN!

That's amazing. I wonder how accurate is the synth engine?

I see that claude’s been in here as well.

Looking at this I can only think one thing: "Just put USB-C in, the connector is ten cents and it's far more convenient than hipster shit like this, you pretentious fucks"

> The PO-32 is not receiving finished drum audio when you transfer a sound or a pattern. It receives structured data:

Wait, isn't this what MIDI is for?
