USB Host Shield 2.0 MIDI transport layer for the FortySevenEffects Arduino MIDI Library and uses the underlying USB Host Shield 2.0 library.
This library is based on the Arduino-USBMIDI.
Install from Arduino Library Manager. Search for UHS2-MIDI.

The libraries below the same calling mechanism (API), making it easy to interchange the transport layer.
