Thank you! I am surprised it doesn't work with iPad Pro. They don't ship to Germany, otherwise I'd buy one and try. If you have an ESP32-S3 device, I can help you with it if it doesn't work.

Oh I found one on Amazon.de and ordered. Will let you know :)

Sorry — I should have added that there is a variation of this device that (allegedly) does work with the iPad Pro, so if you have time to amend your order…

I don't know why this one would work and the other not, but my guess will be that this one has a chip that doesn't offer up a disconnected output device as well (which would be my totally uneducated guess as to why my iPad hates the other cable and the Mac, which has switchable output devices, doesn't)

There was an ESP32 board I wanted to try (below) but it looks like it's a 1.8" sibling of the one you are using so maybe I'll just track down the one you're using.

Added some info on the chip here:

Of course, what we are missing here is audio output :))) how are we going to listen to it? This S3 board has a tiny speaker, and I think for a demo it will work just fine, but :))

Yes. I just started a comment asking the same. Are there S3 boards with better audio breakouts?

There's an S3 audio board but there's no need, a real guitar interface is a much better option.

We need to get low-latency audio interfaces for this usage context down to (low) dozens of dollars rather than hundreds.
