Page 824 highlights

• Start and End fields: These fields define the boundaries of the project segment that you want to write to the bounce file. The defaults for these fields are set in the following way: • If the Cycle function is engaged, the boundaries are set to the locator positions. • If a selection is made in the Arrange window, the boundaries are set to the selected area. • If neither of the above is valid, the boundaries encompass the entire Logic Express project. In any case, you can adjust the start and end positions manually-for example, if you want to take into account a MIDI sound module (mixed via an aux channel strip) that falls outside the bounce start and end positions. Tip: It's often a good idea to set the end position of the bounce a little bit past the end of the last region. This ensures that reverb tails and echoes from delay plug-ins are not chopped off. The amount of extra time needed depends on the effect settings used. As you adjust the Start and End position parameters, you are shown the hard disk space requirements for the bounced file above the Cancel and Bounce (Bounce & Burn) buttons. • (Bounce) Mode buttons: You can create the bounce file in real time or offline: • Realtime: Creates the bounce file in real time. Use this setting when you want to bounce audio and instrument tracks, plus external MIDI sound sources that are routed into the Logic Express Mixer via aux channels. • Offline: Accelerates the bounce process, depending on the complexity of your arrangement and available system processing power. This setting also allows you to bounce arrangements that would normally exceed the processing power of your system, if trying to play them in real time. Offline bouncing is limited to internal sources (audio or instrument tracks). External MIDI tracks and audio channel inputs are deactivated during offline bounces. The Offline Bounce mode is only available to the output channels of devices that use native audio driver systems (Core Audio). DSP-based audio hardware cannot make use of offline bouncing due to the nature of its stream-oriented technology. (In other words, these devices only work in real time.) Other software applications that are fed into your Logic Express Mixer via ReWire can be bounced offline. • Bounce 2nd Cycle Pass checkbox: The bounce process takes two repetitions of the cycle range into account, with the creation of the bounce file starting at the second repetition. This is useful if you want effect tails (from the first cycle pass) to be added to the start of the bounce file. • Include Audio Tail checkbox: The bounce file is extended as far as necessary to include any instrument release and effect tail. 824 Chapter 29 Bouncing Your Project

Start and End fields:
These fields define the boundaries of the project segment that you
want to write to the bounce file. The defaults for these fields are set in the following
way:
• If the Cycle function is engaged, the boundaries are set to the locator positions.
• If a selection is made in the Arrange window, the boundaries are set to the selected
area.
If neither of the above is valid, the boundaries encompass the entire Logic Express
project.
In any case, you can adjust the start and end positions manually—for example, if you
want to take into account a MIDI sound module (mixed via an aux channel strip) that
falls outside the bounce start and end positions.
Tip:
It’s often a good idea to set the end position of the bounce a little bit past the end
of the last region. This ensures that reverb tails and echoes from delay plug-ins are not
chopped off. The amount of extra time needed depends on the effect settings used.
As you adjust the Start and End position parameters, you are shown the hard disk space
requirements for the bounced file above the Cancel and Bounce (Bounce & Burn)
buttons.
(Bounce) Mode buttons:
You can create the bounce file in real time or offline:
Realtime:
Creates the bounce file in real time. Use this setting when you want to
bounce audio and instrument tracks, plus external MIDI sound sources that are routed
into the Logic Express Mixer via aux channels.
Offline:
Accelerates the bounce process, depending on the complexity of your
arrangement and available system processing power. This setting also allows you to
bounce arrangements that would normally exceed the processing power of your
system, if trying to play them in real time. Offline bouncing is limited to
internal
sources (audio or instrument tracks). External MIDI tracks and audio channel inputs
are deactivated during offline bounces. The Offline Bounce mode is only available
to the output channels of devices that use native audio driver systems (Core Audio).
DSP-based audio hardware cannot make use of offline bouncing due to the nature
of its stream-oriented technology. (In other words, these devices only work in real
time.) Other software applications that are fed into your Logic Express Mixer via
ReWire can be bounced offline.
Bounce 2nd Cycle Pass checkbox:
The bounce process takes two repetitions of the cycle
range into account, with the creation of the bounce file starting at the second repetition.
This is useful if you want effect tails (from the first cycle pass) to be added to the start
of the bounce file.
Include Audio Tail checkbox:
The bounce file is extended as far as necessary to include
any instrument release and effect tail.
