Create your MIDI signal path
MIDI signal path overview in the Logic Pro Environment
Before any MIDI events received at your computer’s MIDI inputs can be recorded by
LogicPro, there must be a connection between two Environment objects:
• Physical Input object: Represents the MIDI In port or ports of your MIDI interface.
• Sequencer Input object: Represents the door into Logic Pro for incoming MIDI events.
In Logic Pro, incoming MIDI events (that arrive at the Sequencer Input object) are always
directed to the selected track in the main window, where they can be recorded into a MIDI
region.
The events played by the MIDI region are mixed with incoming events (if any), and sent to
the Environment object that the track is routed to. From here, the events are directed to a
MIDI output (see Assign output connections in the Logic Pro Environment).
You can insert objects into the signal path between the Physical Input object and the
Sequencer Input object if you wish—a MIDI monitor object, which allows you to see
incoming MIDI events, for example.
You can also insert objects between the track and its destination object, enabling other
Environment processing. The track itself is not represented by an Environment object,
but you can use the Reassign Track shortcut menu to route the track’s output to an
Environment object—a MIDI region on a software instrument track routed to a mapped
instrument object, for example.
Insert an object between the track and its destination object
1. In the Logic Pro Environment, choose New > Mapped Instrument.
2. In the Tracks area, Control-click the track header to open the Reassign Track shortcut
menu, then browse to the mapped instrument.
