M-AUDIO MIDISPORT 8x8/s - Manual (Page 22)

Patchbay Operation
The MIDISPORT functions as a MIDI patchbay that is capable of routing and/or
merging MIDI data from any MIDI input port to any MIDI output port. This
integrated MIDI patchbay is active whenever:
• the MIDISPORT is in a MIDI Interface Mode (USB, PC or MAC) but not in
use as a MIDI interface. This is indicated by a blinking Mode LED (USB, PC
or MAC), or
• the MIDISPORT is in Thru Mode.
Eight patchbay programs are stored internally within the MIDISPORT. A ninth
program which connects all ins to all outs is activated when the MIDISPORT is
placed in Thru Mode. The MIDISPORT remembers each of these programs
internally and will recall them each time it powers up. It will also remember the
current patchbay program number as it powers up.
The eight programs may be modified via the Remote Control software. The
current patchbay program may be selected in either of three ways: via the
Remote Control software, via the RESET pushbutton on the front panel of the
MIDISPORT, or in response to MIDI program change messages sent to MIDI In-8
on channel 16 (this last option is only available when the MIDISPORT is not in
MIDI interface mode).
The RESET pushbutton on the MIDISPORT front panel is actually a dual-
function pushbutton. If you press and release the button within a second, you
will send "reset" MIDI messages out all output ports. However, if you press the
RESET button in and continue to hold it beyond one second, it will allow you to
view and/or change the patchbay program. To simply view the current
program number, press the RESET button until 7 of the 8 MIDI IN LED’s light
up. The one LED that is not lit will indicate the program number (1-8). Quickly
release the RESET button and no changes will occur. However if you continue to
hold the RESET button in, the unit will step through the programs until you
release the RESET button. This is how you manually select a program from the
front panel.
As mentioned earlier, when the MIDISPORT is in a stand-alone mode (not being
used currently as a MIDI interface) it may accept patchbay program changes
from an external source such as a MIDI controller keyboard. To do so, simply
attach the MIDI out of the external controlling device to the MIDI In-8 of the
MIDISPORT. Then send program change messages on MIDI channel 16. This
will set the MIDISPORT program to one of its internally stored programs, 1-8.
SMPTE Operation
The MIDISPORT contains an integrated SMPTE reader/writer/regenerator that
may be used by your computer’s application to synchronize itself to the outer
