Ongoing Research and Development for the Plogue chipsounds (plogue.com/chipsounds), plogue XXXXXXXXXX VST/AU Effect and other retro computing geek stuff.
The graph on the left looks like output frequency vs. n for an 8-bit clock divider circuit of sorts. The graph on the right looks like output vs input data for a cheap 8-bit D/A. Am I close on either? :)
What curves are these? POKE'd numbers vs. frequency in Hz?
ReplyDeleteSadly can't say, else I'd disclose what I'm working on. Why do I put it online then? Just to show that i'm working! (trying hard here)

ReplyDeleteHi Skrams.
ReplyDeleteIts the FM tables in the OPLX chips.
Im just starting at the beginning and evaluating the mountain of detail yet to be figured out at this point.
I know lots of info has been published about them, but again, i like to figure things out mostly by myself, and not look at anybody's code.
ReplyDeleteHowever publications like
