Physical Input Objects
The Physical Input object represents the physical inputs of your MIDI interface. You can
only have one of these objects in the Environment.
The Physical Input object receives MIDI signals from the inputs of the MIDI interface(s)
connected to your computer. This object has a total of 65 outputs.
The outputs follow the input assignment of all connected MIDI interfaces. The top output
(SUM) carries the MIDI events for all individual outputs that are not cabled separately.
Remote control events are intercepted at the Physical Input object, and are not passed
through to its outputs. Because of this interception, remote control events will not reach
the Environment, or be recorded on Arrange window tracks.
