# MIDI over USB {#md_pages_MIDI-over-USB}
There are some differences in MIDI over USB implementation between different types of Arduino-compatible boards. This page provides an overview and some board recommendations if you're planning to build an Arduino MIDI device with MIDI over USB support.

Once you have working SAMD11 MIDI over USB firmware, the usage is the same as the previous section about the ATmega16U2.
I wouldn't recommend this approach.

+MIDI over USB is not yet supported on these boards, although the hardware may support it.
+Apart from MIDI over USB, the Control Surface library works as expected. Other features (like MIDI over Serial) are supported.

These chips include FTDI chips (Nano and Duemilanove) and the CH340G or CP2102 (both popular on Chinese "Arduino" clones).
While MIDI over USB is not supported on these boards, you can still use Hairless. Just instantiate a `HairlessMIDI_Interface` at the top of your sketch.

+The ESP32-S2 and ESP32-S3 chips have native USB support, and MIDI over USB is supported by Control Surface when using version 3.0.0 or later of the `arduino-esp32` core.
+At the time of writing, this version has not yet been officially released, and you may need to add the development release link to the boards manager URLs to install it (see https://docs.espressif.com/projects/arduino-esp32/en/latest/installing.html for more information).

+To enable MIDI over USB support, select the `"USB-OTG"` mode in the Tools > USB Type menu.

-That being said, both the ESP8266 and the ESP32 have built-in WiFi, so you can use rtpMIDI, using the [AppleMIDI library](https://github.com/lathoub/Arduino-AppleMIDI-Library), for example.
-An alternative is to use Open Sound Control (OSC). This is not MIDI, it's an entirely different protocol, built on top of UDP. It can be used for bidirectional communication between audio software and control surfaces. I've successfully used this to build a control surface for Reaper.

OSC is not directly supported by the Control Surface library, but they can be integrated relatively easily.
The ESP32 also has Bluetooth support, so you can use MIDI over BLE. This is supported by the Control Surface library using the @ref BluetoothMIDI_Interface.
