This doesn't even need to be an April Fools. I've worked on building vocoders and other synths and it's basically just code. A lot of it written in C and C++.

This doesn't even need to be an April Fools. I've worked on building vocoders and other synths and it's basically just code. A lot of it written in C and C++. Much of it open source. There's also no-code tools like Reaktor that I think you can use code templates to get started (haven't used it in like a decade) A prototype like this is literally a weekend project, completely possible with today's technology.
