Wait, isn't this what MIDI is for?

Sure, but being able to share the 'data dump' at the end of a Youtube Video is so much more fun/likely to be used.

It's sending sound parameter information (e.g. filter cutoff at 12khz, resonance at 1.6, Q of 0.89) along with note information (e.g. start playing note A4 with velocity 80). You could absolutely use a MIDI CC channel to convey this information. The OP-32 chooses a different route and encodes this into an audio signal so that it can transmit it over the air using the speaker/mic instead of a wireless stack.

I bet it sounds like a dial-up tone!

All it means is that the PO-32 is not a sampler, it's a synthesizer, so it receives a "preset" for the synth rather than an audio sample.

It is but I don’t think this Pocket Operator has MIDI without adding third party hardware.

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