How to make a Music Synthesizer - The 'AMY' Library is unbelievably powerful, its a game changer.

Can You Build a Music Synthesizer with Just 12 Lines of Code on an ESP32? 🎹🔧 In this video, we explore the Amy Synthesizer Library running on the ESP32 microcontroller — showing you how to turn just a few lines of code into a fully functional polyphonic synthesizer! 🎶 Learn how to install Amy, configure I²S DAC outputs, and play a recognizable tune (Tubular Bells!) using MIDI note sequences and voice cycling. Whether you're a maker, coder, or synth enthusiast, this beginner-friendly walkthrough is your first step into DIY embedded sound synthesis. But.. Can it play Doom.. No, but it can play Tubular Bells ✅ Perfect for Arduino and ESP32 fans ✅ Real audio demo included ✅ Open-source, expandable project 📚 Explore the Amy library, experiment with sound, and dive into embedded music creation! #ESP32 #Synthesizer #Arduino #AmySynth #DIYMusic #MIDI #EmbeddedAudio #OpenSourceSynth Note: If this fails to compile with errors related to I2S, you may need to roll the ESP32 Core version back to 3.1.1. The AMY library was using calls to several functions that were changed after v3.1.1. Try it first before rolling back as the issues may have been resolved by now. Code: Please Note: Youtube does not permit the use of angle brackets( the two keys between "M" and "/" ) due to the risk of HTML injection. I have used "*(*" and "*)*" as a crude way of indicating these. You will need to find and replace these before the code will compile. #include (*AMY-Arduino.h*) int n,v; String Msg; char buf[20]; int notes[30]={ 69,64,71,64,67,69,64,72,64,74,64,71,72,64,69,64,71,64,67,69,64,72,64,74,64,71,72,64,71,64}; void setup() { amy_config_t amy_config = amy_default_config(); amy_config.features.startup_bleep = 1; amy_config.i2s_bclk = 4; amy_config.i2s_lrc = 6; amy_config.i2s_dout = 5; amy_start(amy_config); amy_live_start(); delay(1000); amy_add_message("r0,1,2K160Z"); v=0; } void loop() { for(n=0;n*(*30;n++) { Msg="r"+(String)v + "n"+(String)notes[n] + "l1Z"; Msg.toCharArray(buf,20); amy_add_message(buf); delay(200); v++; if(v*)*2) v=0; } } Chapters 00:32 AMY Library by Shorepine software 00:40 Arduino Code 02:21 Code to play Tubular Bells 04:12 Playing Tubular Bells
