Port Routing: Understanding Iconnectmidi 2+ Midi - iConnectivity iConnectMIDI2+ Owner's Manual

About the "Running Status on DIN ports" checkbox (under MIDI Information): this
defaults to being disabled/not transmitted (white), since it must be implemented – and
implemented correctly - in the receiving device to function. As a practical matter,
Running Status is a "leave it off unless you know otherwise" parameter.
Running Status is part of the MIDI spec, implemented to reduce the amount of MIDI
data that must be sent. It works by assuming that the first part of the message—the
Status byte, for example Note On—is the same as in the previous message, therefore
only the Data bytes need to be sent. With Running Status disabled, the Status byte is
followed by the Data bytes as normal, e.g. "This is a note [Status]; it's a C3 at velocity
105, etc. etc. [Data]; with Running Status enabled, only the first Note-on needs to be
sent, and you don't need another Status byte until you send a different kind of MIDI
command - for example if you step on or lift the sustain pedal.
Port Routing tab
If you haven't done so, please read the important section above entitled Port Routing:
understanding iConnectMIDI 2+ MIDI before reading this.
The Port Routing screen (actually two screens in the iOS version) is a simple routing
matrix, but it accesses one of the iConnectMIDI 2+ 's most sophisticated features: the
ability to "patch" 16-channel MIDI streams wherever you want them to go, only where
you want them to go.
In the Mac and Windows versions of the software, ports are shown in the left column
and potential routing routes in the right one. Just select a Port in the Ports column and
enable or disable each route in the Port Routing column on the right. (To select multiple
Ports, hold down the Command key on Mac/Control key in Windows.)
The iOS version works a little differently. From the Main Menu you tap the Port Routing
button, which brings up screen of available ports. Then you tap one to bring up another
screen of potential destinations, where you enable the routes by tapping on them.
