Release all DSP resources on Audio Unit bypass (Mac only)
Some Audio Unit hosts dynamically bypass plug-ins when they are not being used during
playback (for example, when no audio is present at the current playback position). During
this dynamic bypassing, UAD plug-ins stay loaded on the device, reducing glitches in
playback.
This setting affects the Audio Units platform only. Checking the option will unload UAD
plug-ins from the device during dynamic bypassing. When the option is checked, UAD
DSP use may be reduced during dynamic bypassing, but the possibility of artifacts
during playback is increased.
Note: Changes to this setting do not take effect until all open sessions containing
UAD plug-ins are closed.
Force Logic to use “Live Mode” for tracks with UAD plug-ins (Mac only)
When UAD plug-ins are used within Logic Pro and this setting is checked, all Logic
tracks with UAD plug-ins are forced into Logic Pro’s Rewire “Live Mode” and DAW
throughput latency is reduced.
Reduced latency is useful for tracking when Logic Pro’s software monitoring feature is
active (when not using Console for input monitoring). When this setting is active, UAD
latency is the same as the I/O buffer size.
When Logic Pro’s Rewire Live Mode is inactive (as set in Logic Pro Preferences > Audio >
Devices > Rewire Behavior) and this setting is not enabled, the minimum Process Buffer
Range value (“Small”) in Logic Pro corresponds to 512 samples, meaning the minimum
possible UAD latency is 512 samples for UAD-2 (the current latency is displayed in
the UAD Meter System Information panel). Latency can be further reduced by using
LiveTrack Mode.
Note: Logic’s live mode is unrelated to UAD-2’s LiveTrack Mode.
On multi-processor machines, Logic Pro’s Rewire Live Mode forces all plug-ins on tracks
with UAD plug-ins (and any aux/buses fed by those tracks) to run on one processor only.
To allow host-based (native) plug-ins to run on all processors under these conditions,
deactivate this setting.
Note: Changes to this setting do not take effect until all open sessions containing
UAD plug-ins are closed.
