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.
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).
On a similar if sillier note note, Korg made a Hatsune Miku guitar effect[1] that was programmable through audio sent from an iPhone app through the guitar pickup.
Annoyingly, the free app isn't available on the US App Store, so open source software would be useful (insofar as the ability to play back a predefined sequence of Vocaloid phonemes using an electric guitar is useful).
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"

I am working on PO-33, doing EMFI.
