Introducing TinyUSB_MIDI_Device_Arduino

This library implements a TinyUSB MIDI device driver for the Arduino MIDI Library that supports multiple virtual cables. The source includes an example that shows how to make a USB MIDI device with 2 virtual MIDI cables. See the project’s README for more details.

This library uses more code space and memory than the Adafruit TinyUSB Library’s API. If you are creating a USB MIDI device with only one virtual MIDI cable, consider using the Adafruit TinyUSB Library’s native MIDI device API instead.

I created this library in response to a Discussion post in the Adafruit TinyUSB Library project. The question asked how to communicate over multiple virtual cables using a USB MIDI device created with the library’s API. As Adafruit TinyUSB Library version 3.7.4 was implemented, the answer is that you cannot. Although you can create a proper multi-virtual MIDI cable USB descriptor, the library’s API does not give you access to virtual cables other than cable 0. This library is an attempt to solve the problem.
