Physical Input Object
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. As such, remote control events will not reach the Environment,
or be recorded on Arrange window tracks.
Sequencer Input Object
MIDI events arrive at Arrange window tracks thru the Sequencer Input object. If
nothing is cabled into the Sequencer Input object, nothing can be recorded in
Logic Express.
Typically, the Physical Input object is cabled directly to the Sequencer Input object but
other objects can be inserted between them. Typical candidates are a monitor,
keyboard, or cable switcher object—feeding various processors such as an arpeggiator,
a delay line, and so on.
You can also cable the output of simple or complex Environment processes into the
Sequencer Input object, in order to record the processed signal.
By default, the Sequencer Input object records on the MIDI channel (or channels) that
the keyboard or MIDI controller (which is sending the MIDI events) is set to.
If you activate the Sequencer Input object’s Channelize parameter, the MIDI channel
assigned to the MIDI object (of the selected Arrange track) is used, and recorded. This
effectively means that if your keyboard is set to MIDI channel 7, and the Arrange track
object is set to MIDI channel 3, all incoming data will be channelized to (and recorded
on) MIDI channel 3.
