MIDI message - the status byte that identifies what it is (for example a note) – remains
the same until further notice. Running status must be implemented correctly by the
receiving device to work; we recommend enabling it only if you can confirm that this is
the case.
Port Information: MIDI in and out for each physical connection – the 5-pin DIN I/O
jacks, the two USB Device Jacks, and up to eight MIDI devices connected to the USB
Host Jack (if you're using a powered hub) – has its own line in this section.
Each one can have its Input and Output enabled or disabled, and the names are
editable.
An additional drop-down menu, Reserved, is available for devices connected to the USB
Host jack (remember, these must be USB MIDI Class-Compliant devices). In this case
an M-Audio USB O2 MIDI keyboard is connected; its name appears automatically to be
reserved, which means it will occupy USB Host Jack Port 1 every time it's restarted.
However, this works for a single M-Audio USB O2; there would be no way to
differentiate between multiple O2s (or multiples of any device).
