+# Host: MIDI 2.0
+
+A minimal USB host example that receives MIDI from a connected USB-MIDI device and prints it over the debug UART, using the USB-MIDI 2.0 host driver (UMP).
+
+## What it does
+
+- Enumerates USB-MIDI devices (`CFG_TUH_MIDI2`) and, on mount, prints the negotiated protocol (MIDI 1.0 / MIDI 2.0) and the number of RX/TX cables.
+- Receives Universal MIDI Packets (UMP) and prints each one, decoding common Channel Voice messages — Note On/Off, Control Change, Program Change, Channel Pressure, Pitch Bend — for both MIDI 2.0 and MIDI 1.0 message types, and falling back to a raw hex dump for anything else.
+
+## Requirements
+
+The board must support USB host mode (provide VBUS to the connected device); some boards need an external USB-A port / host adapter.
+
+## Configuration
+
+Notable `tusb_config.h` settings:
+
+```c
+#define CFG_TUH_ENABLED             1
+#define CFG_TUH_HUB                 1
+#define CFG_TUH_DEVICE_MAX          (3*CFG_TUH_HUB + 1)
+#define CFG_TUH_MIDI2               CFG_TUH_DEVICE_MAX
+#define CFG_TUH_MIDI2_RX_BUFSIZE    512
+#define CFG_TUH_MIDI2_TX_BUFSIZE    512
+```
+
+## Building
+
+CMake:
+
+```bash
+mkdir build && cd build
+cmake -DBOARD=raspberry_pi_pico ..
+cmake --build .
+```
+
+Make:
+
+```bash
+make BOARD=raspberry_pi_pico all
+```
+
+## How to use
+
+Plug a USB-MIDI device (keyboard, controller, or interface) into the board's USB host port. On attach the debug UART prints the mount/descriptor info; then playing notes or moving controls on the device prints the decoded MIDI messages.
