On reception (drum computer to host), the Windows and Mac API's undo running
status, so I receive a series of complete MIDI messages. I only know that the
drum computer is using running status from the old DOS days.

However, I have been able to send multiple messages at once WITH running status
(on Windows, with midiOutLongMsg() ), and it works fine. I just assume that the
bytes are sent "as is" on the MIDI transport. But it's hard to verify these
days...
