# synthio_midi_synth.py - pretty usable MIDI-controlled synth using synthio in CircuitPython
# 11 May 2023 - @todbot / Tod Kurt
# Uses cheapie PCM5102 DAC on QTPY RP2040
# Video demo: https://www.youtube.com/watch?v=N-PbbWWDE6k
# Features:
# - midi velocity controls attack rate (gentle press = slow, hard press = fast)
# - notes have small random detune on all oscillators to reduce phase stacking
# - adjustable number of detuned oscillators per note 1-5 (midi controller 83)
# - five selectable waveforms: saw, squ, sin, noisy sin, noise (midi controller 82)
# - vibrato depth on mod wheel (midi controller 1)

I've spent the day trying to get this setup working with GitHub and given the number of gotcha's I encountered, it seemed like a good idea to document how I finally got this working with as few hacks as possible. There's a lot of documentation out there (some of it old and misleading) and committing here for posterity will help me remember this when I inevitably need to do this again.

Rationale

Passwords are simply not enough these days. Regardless of the company, breaches (and the associated Personally Identifiable Information harvested) are a matter of not if, but when. There are a number of things you can do to protect yourself, but being on the tin-foil-hat side of paranoia, means there are a few Commandents that I adhere to (and recommend for other folks)[Insert link to Fight Club Rules for the Secure Internet].

That being said, if you use 2-factor authentication and have committed to using a hardware token such as the Yubikey, then you're already ahead of the curve. The problem is that wh
