Customize Control Bar from the shortcut menu. Select the Sample Rate checkbox in the
Customize Control Bar dialog.
Match a file’s sample rate with the project sample rate
In Logic Pro, use the Project Audio Browsers Copy/Convert File(s) command (which is
also available by Control-clicking the Project Audio Browser or using the corresponding
key command), then replace the file in the project.
Logic Pro performs a real-time, native sample rate conversion. Any sample rate available
in Logic Pro (via Audio > Sample Rate) can be used for the conversion—even if your audio
hardware doesn’t support the selected sample rate.
The native software sample rate conversion function matches the sample rate of any audio
hardware, thereby allowing the playback of projects on virtually any audio system, even if
the hardware is—in sample rate terms—not compatible. Nothing is lost in the process. Any
internal processing and bouncing is always performed at the original sample rate, and at
the highest quality, even in cases where the hardware doesn’t support a particular sample
rate. This feature allows you to work on projects originally created on high-end audio
systems, with lower-end setups.
For example, imagine a project was created with audio hardware set to operate at 96kHz.
Moving this project to another computer (for example, a notebook computer) that doesn’t
support the original project’s sample rate will result in the wrong playback speed. The
native real-time sample rate conversion function will counteract this effect, allowing
correct playback of the project on the portable computer, at any sample rate.
Note: Higher sample rates not only use up more disk space, but also require more
processing.
Set the start and end points for a Logic Pro project
A project normally starts at position 1 1 1 1 (as shown in the LCD, in Bars mode or in Bars
and Time mode). You can move the project start point to an earlier position, allowing
upbeats or program change commands to be played before the first downbeat. You can
also move the project end point; for example, to remove unused bars at the end of the
project.
Set the project start point
In Logic Pro, drag the Project Start marker in the ruler to the left or right.
