I’ve been on the look out for kits for a DIY wavetable synth but haven’t found anything yet.
I just ordered a couple of WeAct STM32F411 “Black Pill” boards - the ones with the QSPI Flash attached (It’s @analogoutput 's fault after this post Braids THT in KOSMO format - #166 by analogoutput).
I reckon it would be a good place to start for wavetables, so it’s going to be added to my long list of projects. Unfortunately I don’t have any projects or resources to suggest. I’ve coded up a couple of naive single wave-form oscillators that I’ve used in a couple of projects, and I’d probably start from there when I get 'round to making something. When I get around to doing anything I’ll share it, but I wouldn’t hold my breath…
Cheers
