➜ NOTE: In some cases, you can use Merge Mode while connected to a computer
via USB, but only if the operating system is not currently running. In this scenario,
the computer serves only as a power supply while MIDISPORT is operating as an
independent device. This is possible, because some computers provide power to their
USB jacks even when shut down or in sleep mode. Please note that it may be necessary
to disconnect and reconnect the USB cable after shutting down the computer for
MIDISPORT to disengage USB Interface Mode and enter Merge Mode.
Check the documentation associated with your computer to see if it provides power to
its USB jacks while shut down or in sleep mode. A separate USB-type external power
supply is not required if MIDISPORT is connected to such a jack.
MIDI Thru Mode
MIDISPORT 2x2 is in MIDI Thru mode when the MIDI Thru - USB/Merge button is set to the
‘out’ position. In this mode, MIDISPORT passes the In A data stream directly to Out A and
the In B data stream directly to Out B. This mode bypasses connected computers and does
not require power to operate. Thus, MIDI Thru mode can always be enabled, regardless of
whether or not MIDISPORT is connected to a computer, or a power source.
