Sequencer input objects

The sequencer input object represents the MIDI input of Logic Pro. You can only have one of
these objects in the Environment.

MIDI events arrive at main window tracks through the sequencer input object. If nothing is
cabled into the sequencer input object, nothing can be recorded in Logic Pro.

Typically, the physical input object is cabled directly to the sequencer input object but other
objects can be inserted between them. Candidates include 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 turn on the sequencer input object’s Channelize parameter, the MIDI channel assigned to
the MIDI object (of the selected track) is used, and recorded. This effectively means that if your
keyboard is set to MIDI channel 7, and the track object is set to MIDI channel 3, all incoming data
is channelized to (and recorded on) MIDI channel 3.
