You'd think they'd do a quick check on the name before committing to it. I remember using Lingo with Macromedia Director, it was a nice little language
You'd be surprised how people will stick to a name.
At my last job, we spent 3 years building an electrical systems product with the same name as an eye scanning company. We had invested in marketing and sales that was practically useless once the executives finally agreed they needed to rebrand. It was the sort of thing that was pointed out on day zero, but the man in charge was too proud of the name. It wasn't even a very good name for our product.
And that was a bet-the-company type of choice. Lingo here is just some little library of no import to Gitlab's business.
I don't think there is much risk of confusion between a microcontroller and an all-in-one retro computer. They also have different numbers (64/64A vs. 65) and the Mega65 isn't prefixed with an 'AT'.
The VZ-1 takes a hybrid approach to its sound generation. Where the CZ line used Phase Distortion Synthesis and the Yamaha DX line used Phase Modulation (incorrectly advertised as FM), the VZ-1 uses Phase Distortion for ring modulation and waveform generation but true Frequency Modulation Synthesis to generate harmonics.
Is my VZ-1 broken? Have I discovered an implementation quirk that nobody on the internet has ever complained about? No and no. My VZ-1 is not broken and on closer inspection at least 1 person on the internet is aware of this problem, and they figured it out for me! Digital synthesis expert acreil got roped into a Gearspace thread about the VZ-1 back in 2021. The discussion starts off not being very interesting until acreil shows up, who then repeatedly gets contradicted by someone who loudly says things that are wrong, and then to put that all to rest acreil finds the relevant Casio patent for the VZ series and drops the bomb that the VZ's don't do phase modulation at all. They do wave shaping.
Excuse me what now? Yes, pedantically wave shaping is phase modulation with a carrier frequency of 0Hz, but why would you call that phase modulation?
