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). https://github.com/pichenettes/mutable-dev-environment?tab=r...

As I understand it, transferring data as audio goes back quite ways, right?

I had a Commodore 64 that could use phillips tape. I'm drawing. blank, but IIRC there were musical instruments (maybe the roland juno 60?) in the 80s that were storing their data as audio, too.

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

The synth engine is an implementation of https://soniccharge.com/microtonic Not sure what "accurate" means in your context though?

How closely it replicates microtonic's, would be my assumption

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"

Pretentious hipster shit is their whole brand.

Would have been easier to say it receives patches - I think most people would get this.

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.

Me too, have been trying to crack this for so long!

Here, this is a lot of fun.
