The Q10 has been my daily driver for years, great keyboard. I see that they're coming out with a split alice [1] though sadly it seems it is only for the Chinese market

I see your point, though strictly speaking, the two products I mentioned mimic 12AX7 tubes, which are preamp tubes. I'm not aware of E2E designs that also mimic power tubes.

Minor correction:

An experienced guitarist cannot distinguish between "captured" amps, or amps which at their core simulate vacuum tubes at the software level. I definitely can't tell the two apart. However, I believe it is easy to distinguish a pure vacuum tube-based circuit from a JFET/MOSFET-based one.

There do exist vacuum tube replacements like the AMT 12AX7WS [1] or Jet City's RetroVales [2], but I would argue that the fact that they try to emulate tubes via transistors is a strong indicator that the natural circuits for both sound distinct enough for guitarists.

Sup-par phrasing is a subtle advantage of non-AI generated text. In the past, I would be put off by this bad phrasing and the typo ("requier") in the text, but these days, it's a signal that a human took the time to write this, which makes me happy to see.

..or is it "sub-par"?

Layoffs might not be the best way to keep talent. Imo, Nintendo did it best back in 2014 [1].

After all these years, I still think that this was a wasted opportunity on Google's side. As is well-known, Google (Googol) is a constant: 10^100. Instead of Alphabet, they should have named the umbrella company AlephBet [1] with a tag line: "we stopped thinking in constants".

Someone should add a grid of mics and speakers inside a keyboard to record impulse responses for different kinds of keys. In this way, one can first do noise cancellation for the currently used keys, and then apply an IR to make the keyboard sound like another one.

"Completely unusable" is an over-exaggeration. By default, assume good will.

> In 1955, he was promoted to tenured associate professor. In December 1957, Asimov was dismissed from his teaching post, with effect from June 30, 1958, due to his lack of research.

I thought the whole point of getting tenure is that you can't get fired.
