Chapter 5 The Environment 159
The MIDI Signal Path
Before any MIDI events received at your computer’s MIDI inputs can be recorded by
Logic, there must be a connection between two Environment Objects, namely: the
physical input and the sequencer input.
In the sequencer, the events are always directed to the selected track, where they can
be recorded. The events played by the track are mixed with any incoming events and
sent to the Environment Object assigned to the track in the Arrange window’s track list.
From here, the events are directed to a MIDI output (see “Direct Output Assignment” on
page 159).
You can insert Objects into the signal path between the physical input and the
sequencer input, as well as between the instrument and the MIDI Out port, to
accomplish other Environment processing. This is done by using cables (see “Cabling”
on page 160).
Direct Output Assignment
You can create a direct output connection from any Instrument Object to a physical
MIDI output by setting the desired output in the Port parameter line, just above the
Channel parameter.
If you click and hold in this line, a pull-down menu will list all individual ports, an off
setting and one general setting (All) for each output connection. The off setting
completely disables the connection to the MIDI interface port. The All option routes the
Object’s output to all available MIDI ports. This may be useful if the device is sending a
pulse, for example.
Note: If you have a MIDI interface with more than one output port (or even several
interfaces which can be stacked, like products belonging to the Unitor family), you can
set up a direct connection to one of the individual ports (1 to 63) of that, or those,
interface/s (for example “Port 1 (Unitor 8)” or “Port 14 (Motu)”).
Any Object with a directly assigned output is indicated by a shaded triangle on its
right-hand side. The triangle is hollow when there is no direct assignment.
