I need an extension that can connect to USB midi devices like a midi keyboard.
Anyone has an extension like that?
I am thinking about creating an extension using this link MIDI  |  Android Open Source Project .

You could try the BLE extension...

MIDI over BLE is always enabled, provided the device supports BLE.
