In SMF files, header fields use big endian, but they are never sent over the wire. (Variable-length quantities also do not appear in in the raw MIDI byte stream.) Everything that is actually a MIDI message has its bytes in the same order as they are sent over the MIDI cable. E.g., the data bytes of the Pitch Bend message use little endian. > can I just send the midi even directly? Yes; with amidi. > I dunno if by mistake I send some cmd that can fuck up the controller :) Other programs allow you to send arbitrary MIDI messages, too; amidi is not any more dangerous than them. Some devices do have commands to store settings in non-volatile memory or to update their firmware, but it is extremely unlikely that you would manage to send them by accident.
