ML Synth Organ Example

Abstract

1. Introduction

MIDI Organ using the ML_SynthTools library (little example arduino project)

The required library can be found here: https://github.com/marcel-licence/ML_SynthTools

All platforms are tested. Actually the sound quality might be a bit limited. The organ supports full polyphony (you can play all 64 notes of the upper manual at the same time). You can modify the sound using 9 drawbars. Percussion is supported (2nd, 3rd). A simple rotary implementation creates a simple (noisy) leslie like sound.

2. Objective

ESP32, ESP8266 based MIDI Organ using the ML_SynthTools library (little example arduino project)

This project demonstrates how C, Arduino, ESP32 can be applied to a real-world Internet of Things (IoT) problem.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Arduino IDE / PlatformIO or a C compiler (gcc)
• Target board where applicable
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/marcel-licence/ml_synth_organ_example.git
cd ml_synth_organ_example

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a mobile dashboard using Blynk or Firebase
• Store readings in a cloud database for history charts
• Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Which microcontroller / board and sensors are used and why?
2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
3. Where is the sensor data stored and visualised?
4. How is power consumption managed?
5. How would you secure the device and its communication?
