Teenage Engineering's PO-32 acoustic modem and synth implementation (opens in new tab)

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.

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).

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!

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

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.

> Wait, isn't this what MIDI is for?

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

Unfortunately I think only a few of the PO's support this transfer method, and I don't think the 33 is one of them. They were never meant to be updated at all, as I understand it.

much simpler, just pull apart the MT VST :P

I am working on PO-33, doing EMFI.

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

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

This was released in 2017 for one thing. Considering that enough people are still interested in it a decade later they probably did something right.

Pretentious hipster shit is their whole brand.
