Recording Delay
This parameter is measured in samples. It allows the recording of Audio Regions to be
delayed by a certain fixed value. It helps advanced users to compensate for the delay
that may be caused by incorrect delay information being provided by the driver.
Normally you don’t have to bother with this parameter.

Max. Number of Audio Tracks
The Audio Engine requires free system memory, which is not assigned to Logic or any
other application. The amount of memory required depends on:
other application. The amount of memory required depends on:
•
the maximum number of tracks to be played
•
the number of I/O channels supplied by the driver
This setting allows you to reduce the amount of memory required by the driver
through a reduction in the number of tracks. This may be useful when you want to run
other applications or drivers simultaneously. Range is from 4 to 255 tracks.

As you change the

value by dragging the slider left or

value will update in realtime.
64 Busses
This checkbox allows the use of up to 64 Bus Objects. Logic Pro normally restricts the
number of Bus Objects to 32. If you need to create more, check this box, and add the
desired Objects.

Universal Track Mode
Universal Track Mode, when engaged, allows the playback of stereo and mono Regions
on a single track. Even-numbered Audio Objects are not regarded as the right channels
of the odd-numbered stereo Audio Objects to their left, and every Audio Object has its
own Mono/Stereo button. Dependent on whether a mono or stereo Region is played
back, the Pan knob will behave as Balance or Pan control. If you play back a mono
Region, and the Pan knob is set to the center position, both channels of the Audio
Object will output the same signal level.

Note:
Universal Track Mode has limited routing capabilities, as it is not possible to
handle the left and right audio channels separately.
The Non-Universal Track Mode is useful if you wish to play different mono files for the
left and right mono channels of a single Audio Object, even when it is assigned as a
stereo track. A stereo/stereo plug-in inserted on this stereo track receives different
signals for the left and right channels.
