STM32 Tutorial Video #101 - USB MIDI Polyphonic Synthesizer

Upgrade your STM32 synthesizer from a basic buzzer to a 10-voice polyphonic digital synth! In this tutorial, we combine TinyUSB MIDI with the internal Digital-to-Analog Converter (DAC) on the STM32F407 to generate multi-waveform, envelope-shaped polyphonic audio in real time. We walk through the voice allocation logic, ADSR envelope state machine, real-time mixing buffers to prevent clipping, and benchmark loop execution performance under heavy polyphonic loads.
