Description

This project can be used as an organ-like instrument or also as a kind of additive synthesizer.

The design is completely different to the organ project but also capable of covering some important features.


---

The project has been tested on PCB ML v1 (ref: https://youtu.be/Lp65Urhy1-U)

It should be compatible with ESP32 Audio Kit and also easy to use with a stand-alone ESP32 with DIY hardware

Supported versions of board library

---

- ESP32 version 1.0.6 from https://github.com/espressif/arduino-esp32/releases/tag/1.0.6

- ESP32 version 2.0.2 from https://github.com/espressif/arduino-esp32/releases/tag/2.0.2

Please be aware that other versions might be not supported.

## Features/Modules

### additive synth module

- 7 voies polyphone

- 9 oscillators per voice

- 5 simple waveforms (+ noise)

- decay setting per oscillator

- organ like percussion

- main low pass filter with variable cutoff and resonance

### delay effect

- variable delay length (max. 250ms)

- variable feedback

- controllable mix

### reverb effect (by YetAnotherElectronicsChannel)

- controllable wet/dry

### oled waveform display

- very stable waveform display based on a convolution algorithm

- supports 128x64 pixel display

### midi interface

- midi can be provided via uart (a dedicated connector on a real PCB)

- midi via serial port (allow rerouting signal via computer)

- midi via USB with additional hardware (not tested)

### supported codecs

- PCM5102a

- AC101

- ES8388
