Brain function is incredibly precious to me (having had great-grandparents with Alzheimer's), and this type of damage has been consistently proven.

I just read my tenth #COVID19 research study in the past month or so that demonstrates COVID infections cause brain changes that may accelerate Alzheimer's disease, are associated with cognitive decline, and cause fatigue, memory impairment, and sleep disorders. (1/?)

For the last month I've been seeing how far I can get CircuitPython into emulating a TB-303 bass synth. With the audiofilters library, you can stack filters to make a 4-pole filter, for that squelchy sound we need
