MIDI Routing
General Info
The AUDIO4c supports up to 10 MIDI ports per USB Device Port, each port containing 16 midi
channels, 5 pin DIN-MIDI I/O port with 16 channels, plus one USB-A host port capable of hosting 8
total MIDI devices (with a separate powered USB hub, not included), for a total of much more MIDI
ports and total channels than are required by mere mortals in this version of reality. Use the Auracle
for X-Series MIDI Routing page to route MIDI ports from any [Source] to any [Destination].
Source
The [ Source ] column on the left lists all available physical MIDI ports on the AUDIO4c, as well as
additional virtual ports such as USB Host Ports HST2 through HST8 which are only accessible when
more physical host ports are made available when adding a powered USB hub (not included) as
indicated in the
General Info section above. For more information on using multiple USB host devices
with a powered hub, see the USB Host Reservation section below. A helpful way to visualize the flow
of MIDI information is to remember:
[ Source ] = From
[ Destination ] = To
To begin this wonderful routing journey, click the icon of the MIDI source port you wish to route
anywhere in the gray rectangle enclosing the port name. The port becomes highlighted in blue, and
the [Destination] field to the right populates with all available routing destinations for the selected
source port... Which is very literally,
