ESP32_Host_MIDI | USB Host (MIDI 2.0 / UMP)

USB-Host-MIDI2

USB host that receives raw Universal MIDI Packets (UMP) from a MIDI 2.0 device and decodes Channel Voice (MIDI 2.0 and MIDI 1.0) to Serial. Mirrors the TinyUSB midi2_host example, on the native ESP-IDF USB host. Packets split across USB transfers are reassembled; internal negotiation messages are not forwarded.

Build

Arduino IDE: Board ESP32-S3 (USB host), USB Mode "Hardware CDC and JTAG". Or arduino-cli:

arduino-cli compile -b esp32:esp32:esp32s3 --library . examples/USB-Host-MIDI2

Hardware

A USB MIDI 2.0 device on the host port (Teensy, Daisy Seed, RP2040, etc.). A MIDI 1.0 device is received too, via the MIDI bytes callback.

Validation

Open the Serial Monitor; play notes on the device. MIDI 2.0 Channel Voice prints decoded (NoteOn n=.. vel=....), and other UMP types print as hex.
