Apple Logic Pro 9 - Manual (Page 1138)

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 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 is channelized to (and recorded on)
MIDI channel 3.
To create a Sequencer Input object
µ
Choose New > Sequencer Input.
To make use of an existing object, drag it to the relevant layer. This does not affect its
cabling.
MIDI Click Objects
The MIDI Click object is used to create note events at bar, beat, and division intervals.
These can be sent to either a MIDI port or the internal speaker.
