Ok, not quite. the wall i hit was i do not, or did not, at all understand how audio samples work, but now, i have learned what/how they are, how they can be passed to a super fast PWM drive or a DAC to produce audio (i have a nice audio-grade DAC so i may make the synth esp8266 or 32 based so you can add drum beats and other stuff via an app or web interface).

Now i know, and am currently learning how sample-tables work, as that is apparently important, if you want to output something more than just pure square wave. But thats just gravy and inconsequential, as it stands i know all i need to know to finish this thing, and shall, once i finish working on a newer, more important project with an immediate deadline, im making a WS2812B strip audio-reactive driver to drive a huge LED array.
