## Arduino 7 potentiometer Synth (Mozzi-based)
/*  (Not so) simple synth based on Mozzi library and a bunch of pots.
 *
 *  This code is derived from the public domain example of an 8 potentiometer
 *  synth from e-licktronic (https://www.youtube.com/watch?v=wH-xWqpa9P8).
 *
 *  Severely edited for clarity and configurability, adjusted to run with modern
 *  versions of Mozzi, extended for polyphony by Thomas Friedrichsmeier. Also,
 *  this sketch will auto-generate fake MIDI events and random parameters, so
 *  you can start listening without connecting anything other than your
 *  headphones or amplifier. (Remove the FAKE_POTS and FAKE_MIDI defines, once

## Rotary_encoder_software_debounced.h
/* Reading from a rotary encoder, with software debouncing.
* Works even on cheap quadrature encoders without any hardware debouncing, _reliably_. */

#define ENCODER_PIN_A PA1    // Input pins. NOTE That these _must_ support intterupts, _and_ interrupts must not interfere with other pins
#define ENCODER_PIN_B PA2    // // (e.g. on STM32F103C8T6, PAx will interfere with PBx)
#define BOUNCE_TIMEOUT 2     // ms
#define USER_INPUT_HIGHER_RES 0 // You probably want this: Gives lower granularity at higher values
