The specs do not address this. It is an error in the MIDI spec in my
opinion, and I discussed it with someone from the MMA several years ago and
they agreed with me. The spec should have ordered things differently OR
required that LSB and MSB are always sent. They did not. The existing spec
design is easy to implement in dedicated hardware but notably harder in
software run on a general purpose machine because you need to pick some
arbitrary timeout.
Every possible ordering/delivery sequence can be found in one or more
devices.
