Apple Logic Express 9 - Manual (Page 1132)

• Aux: Auxilliary channel strip, used as send returns for all channel strips (via Sends), as
subgroup channels, and as individual output destinations for multi-channel software
instruments (EXS24 mkII, for example).
• Instrument: Used as the destination for arrange (software) instrument tracks.
• Output: These channel strips represent the physical outputs of your audio interface.
You can choose either mono or stereo (paired) outputs.
• Bus: Primarily retained for compatibility with projects created in earlier versions of
Logic Express. The functions of bus objects are now performed with (the more flexible)
aux channel strips in Logic Express.
• Master: Only one master channel can exist in a project. This is the master volume control
for all channel strip types (except external MIDI channel strips).
MIDI Channel
Allows you to choose a MIDI channel that can be used to control the channel strip.
Q-Reference
Allows you to use the transients of regions on the channel strip for audio quantization,
if part of an Edit Group. Otherwise, the checkbox is unavailable.
Flex Mode
Allows you to choose a time-stretching algorithm that can be used to process the audio
material on the selected channel strip.
Show Options
Select the corresponding checkbox to show EQs, Inserts, Sends, and I/Os on the selected
channel strip(s).
Input Channel Strip
You can only create input channel strip objects in the Environment. In general, you will
not need to do so, as all audio hardware inputs are automatically seen by audio channel
strips, and can be monitored and recorded.
Input channel strips are primarily included for compatibility with earlier versions of
Logic Express, and for use with certain audio hardware devices. The input channel strip
allows you to directly route and control signals from your audio hardware’s inputs. Once
an input channel strip is assigned to an audio channel strip, it can be monitored and
recorded directly into Logic Express, along with its effect plug-ins.
The signal is processed, inclusive of plug-ins even while Logic Express is not playing. In
other words, input channel strips can behave just like external hardware processors. Aux
sends can be used pre- or post-fader.
