Miniphonic: An Arduino-Based Audio Synthesis Platform
https://www.elektormagazine.com/articles/miniphonic-arduino-based-audio-synthesis-platform-1
In this project, we use an Arduino Uno R4 board and other hardware to make a versatile and performing sound synthesizer and MIDI sequencer. In the first part of this series on audio synthesis, we describe the block diagram and the main functions of the Basic Synth software.
