I have 9V on VIN for this.
Anyway. To solve the problem on EVERY this line of code below:
MIDI_CREATE_INSTANCE(HardwareSerial, Serial1, MIDI);
need to replace this line:
MIDI_CREATE_DEFAULT_INSTANCE();
On EVERY Serial is USB connection, Serial 1 is on TX and we need to point out to this in code.
After that change communication to Stomp was established and my MIDI controller works like a charm.
Again, this only applies to Arduino Nano EVERY - it is not the same Arduino as Nano
