# 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)
