Chapter 1 Audio Hardware and Drivers 13
Release in Background if Stopped
We strongly recommend that you do not enable this option until the DAE and
standalone Digidesign Core Audio driver support this feature.
Activation of this parameter will release the TDM hardware when Logic is not in play or
record mode, allowing you to address the hardware with another application—such as
the Pro Tools software or a sample editing program.
Common Parameters
At the bottom of each Drivers pane you can see four pop-up menus, which provide you
with the following settings.
Process Buffer Range
This parameter determines the size of the native buffer that is used to compute mixers
and effects. You can choose between Small, Medium, and Large buffer sizes.
Note: Larger buffer sizes will increase latency. Dependent on CPU speed, buffer sizes
that are too small may compromise realtime audio processing.
Note: This setting is not valid for the DAE.
Rewire Behavior
When sending MIDI data to a Rewire compatible software instrument, you can choose
between:
• Playback mode: use when playing back MIDI tracks via Rewire. This setting requires
less CPU power.
• Live mode: use when playing a Rewire instrument live. This setting requires more
CPU power.
Note: Please note, that this setting is not valid for the DAE.
Maximum Scrub Speed
Sets the maximum scrub speed. Normal means the playback speed is used, Double
playback speed is twice as fast.
Scrub Response
Determines the reaction time for audio scrubbing. Choose the value that works best for
your system configuration. Options are: Slow, Normal, Fast, Faster.
