That is because the LP sends MIDI using running status, and there
is no way to reset it (i.e. force a status byte on the next message),
except a power cycle. The top row uses controller events while the
rest uses key up/down. After re-opening the device the driver code
needs a status byte, and usually using the top row will provide one
(assuming the last event in the previous session was a key one).
Actually *most* events are unambiguous even without a status byte,
but you'd need some ad-hoc code in the driver to exploit that.
A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
