Edit: Is this what AI "thinks"? Or a plausible take generated from training on Reddit threads? Because it sounds suspiciously like the latter.

Example 1: Pianos are tuned with stretch tuning, where the high notes are tuned higher than their theoretical pitches, and vice versa for low notes. That's because of a thing called inharmonicity, where the overtones of short piano strings don't form perfect ratios with the fundamental. Maybe that has something to do with short strings vibrating more like metal cylinders than rods?

Example 2: French horns have a lot of tubing! The valves let you include different lengths of tube into the air column. With a single valve combination, the player can hit the fundamental and all the partials up until their lips can no longer take it. To play a scale or melody, they switch between different horn lengths, choosing the partial that will sound closest to the pitch they're going for. Really, all brass instruments function this way, I just mention French horns because I like them.

Example 3: String quartets tune their chords with each other on the fly. If you listen to a string quartet practice, they'll spend a good amount of time holding and adjusting intonation to each other. So unlike in the equal tempered world of keyboard tuning, strings and most instrumental ensembles are constantly adjusting to make their harmonies sound sweeter. Equal temperament doesn't come into play, unless you add a piano, which sort of forces everybody to uncomfortably conform to the limitations of set it and live with it keyboard tuning.

"No I mentioned the bisque."

In MIDI, there are NOTE_ON and NOTE_OFF events, for when you press and release each key. The NOTE_ON has pitch and velocity parameters. The NOTE_OFF just has pitch parameter (maybe it has velocity as well I can't quite remember, it's off the point). So if you push middle C, it might look like this:

NOTE_ON 60 (middle C) 98 (velocity), NOTE_OFF 60

Some keyboards never send NOTE_OFF events, instead they send NOTE_ON with velocity 0. On these keyboards, pressing middle C looks like this:

NOTE_ON 60 98, NOTE_ON 60 0

Both are valid MIDI streams, and all stream processors should react appropriately to both. This app likely does not correctly map zero velocity NOTE_ON events to NOTE_OFF with the same pitch.

Not exactly the point of the article, but this is all sort of wrong. CDs use a sample rate of 44.1 kHz per channel, not 22 kHz. I'd hazard this cuts down on rounding errors from having only one sample per 22kHz range. DAT used 48 kHz I believe to align evenly with film's 24 frames per second. 96 kHz is commonly used for audio today, and the additional accuracy is useful when editing samples without producing dithering artifacts within human hearing range.

Savage.

The opposite happened with the Matrix. I think I saw 1 bus stop poster for it, and didn't know what it was until multiple people at work said, "you have to see it!" Too bad they never made a sequel.
