[PD] ring buffer with an array

[Alexandre Torres Porres]

Hi folks, I'm trying to implement a ring buffer with a table for a sampler
patch based on an array.

But I'm having the hardest time cause it always "clicks" when I start
writing back on the beginning of the array.

I made this simple test attached below using metro. But I'm figuring the
flaw is because is not trivial at all to keep control data in sync with
audio blocks

any hints or ideas?

thanks
