// Code is partly based on Knob_LightLevel_x2_FMSynth example from Mozzi Library

// Although the code designed to work on Sitka Instruments WS-1.0 synth, it should
// be pretty easy to adapt to run on other arduino/mozzi-based setups
// be pretty easy to adapt to run on other arduino/mozzi-based setups.
// Edit config.h to match your setup.
//
// This code is licenced under GPL v3 or later
//ToDo:
//test how accurate and fast oversampling is
//smooth harmonics knob?
//rework LFO/Intensity so when LFO rate is 0, intensidy doesn't depend on its phase
//optimize MIDI input (maybe neohwserial and this parser might help https://github.com/eclab/grains/tree/main/midi)
//add ramp LFO
//add uneven rations (like 3:2, 3:5)
