# wavetable_synthio_synth.py -- Demonstrate new synthio.Synthesizer as wavetable MIDI synth
# 15 Apr 2023 - @todbot / Tod Kurt
# video demo: https://www.youtube.com/watch?v=uUnS3nR2K-8

# Hooked up to generic I2S DAC
# Uses two pots:
#  knobA - selects the base wave
#  knobB - selects the mix between base wave and next wave

# 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)

#
# Uses LEDs on Adafruit Funhouse but adaptable to any CircuitPython WiFi board.
#
# To see what's going on, download MQTT-Explorer from http://mqtt-explorer.com/
# Launch it and connect to the MQTT host/port/username/password as in secrets below.
#
# From MQTT-Explorer, you should see messages to "todbot/feeds/hello" every 3 seconds
# And then you can go to the right of MQTT-Explorer to Publish, fill in "todbot/feeds/light",
