Hi, Could someone officially confirm if the UNO r4 minima is both HID compliant AND supports midi over USB natively.
Web searches keep providing conflicting information.
Thank you.
Hi @rssd.
I'm not sure what you mean by "compliant". I can tell you that the UNO R4 Minima does have HID capability.
For example, you can use the board with the "Keyboard" library to emulate a keyboard or the "Mouse" library to emulate a mouse.
I'm not sure what you mean by "natively".
The hardware definitely does have support. However, I am not aware of any Arduino libraries that make it easy to add the USB MIDI capability to your sketches.
These are the libraries I am aware of:
From my tests, none of these provide a USB MIDI capability for the UNO R4 Minima. The beta version of the "Control Surface" library is compatible with the UNO R4 Minima, but only the serial MIDI capability has been implemented for that board, while the USB MIDI remains unimplemented.
I know that several Arduino community members have created projects with the UNO R4 Minima board using serial MIDI.
