In/Output
Input Selection
The Input field allows you to select the desired audio input of your audio hardware.
This input (or input pair) supplies an audio signal to the track when recording. If
Monitoring is switched on, the signal of this audio input will be routed to the output
(or bus) selected in the Output field, when the track is record enabled. The number of
available inputs is determined by the audio hardware in use.
Note: The Input slot is used for the insertion of software instruments on Audio
Instrument Objects, and is known as the “Instrument Slot” on these channels. Further
information can be found in the first section of the Plug-In Reference manual.
Output Routing and Sub Groups (Busses)
The slot directly below the Input slot determines where the signal of the Audio Object
(mixer channel) will be sent. The number of outputs that are available is determined by
the audio hardware in use.
You can select between Output Objects and Bus Objects, which can function as mixer
subgroups. If the Audio Object is stereo, the bus will also be stereo. If the bus is a
stereo Object as well, the entire (Mixer) signal flow will be stereo—in each of the
busses available in Logic, if this is desired.
Hold Option while selecting the inputs or outputs of a single channel to change all
selected Audio Objects simultaneously. (See also “Multiple Selection of Audio Objects”
on page 269.) Please note that inputs are only changed on (selected) Audio Objects of
the same status: mono or stereo. This facility allows you to easily select a single input
for all audio tracks.
Double-click on Output slot
Double-clicking on the Output slot on any audio channel will “jump” to the allocated
Output channel fader, accelerating navigation in the Mixers.
