Audio programming

2021-10-25 11:59 PDT

I started working on some audio programming stuff to make music; I picked up a 4x8 NeoTrellis and dug up my Teensy and audio shield for it.

I've been trying to figure out how to get sound out of the Teensy (the docs seem to be rather lacking) using PlatformIO, and I finally got that working.

I'm going to try to turn the NeoTrellis into a sequencer, should be fun to play around with.
