TinyMIDIUSB - ESP32-S2 alternative MIDIUSB Library for Arduino

One of several ESP32 repositories

Glue transport layer USB-MIDI to ESP32TinyUSB
This should support Control Surface, which is extensively documented.

MIDIusb is the class for ESP32TinyUSB, declared in ESP32TinyUSB/src/midiusb.h
MidiUSB is wanted in USB-MIDI.h and USB-MIDI_defs.h
MIDIusb MidiUSB; declaration gets error: 'MIDIusb' does not name a type in MIDIUSB.h;

• don't know why; it works in midi.ino..?

#define MidiUSB MIDIusb gets error 'midiEventPacket_t' does not name a type
in USB-MIDI\src/USB-MIDI.h, so relative progress

Arduino has its own midiusb.h?

class TMidiUSB:public MIDIusb gets error: expected class-name before '{' token,
but class MidiUSB:public EspTinyUSB is accepted..??!
Arduino evidently ignores midiusb.h contents!!?
In libraries/ESP32TinyUSB/src/, renamed midiusb.h to Tmidiusb.h as a work-around.

USBMIDI_CREATE_DEFAULT_INSTANCE is defined in libraries/USB-MIDI/src/USB-MIDI.h
as USBMIDI_CREATE_INSTANCE(0, MIDI)

11/14/2021: compiles, but does not link

Need cMidiUSB.cpp to create e.g. MidiUSB.read() from ESP32TinyUSB read()

11/14/2021: compiles and links

Even though only read() is implemented in MIDIusb.cpp

• write()'s are handled by an instance of Esp32TinyUSB's MIDIusb
