ESP32-S3 SD MIDI Sampler Synthesizer DIY Arduino

This video demonstrates how you can use ESP32S3 as a polyphonic sampler midi controlled synth. You can also see two other devices: ESP32 I2S monitor/recorder which recorded the audio for this clip, and Pro Micro USB to Serial MIDI bridge which allows playing midi file on a PC and send midi commands to the ESP32-S3 sampler. The sampler operates wav-samples on a micro SD card in real-time. The size of a sample set is only limited by FAT32 capabilities. The sampler also features a built-in reverb fx. Projects are easy to build and to customize using Arduino IDE.
