Release all DSP resources on Audio Unit bypass
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, which reduces glitches in playback.
This setting affects the Audio Units platform only. Checking the “Release all
DSP resources on AudioUnit bypass” option will unload UAD plug-ins from
the device during dynamic bypassing. When the option is checked, UAD DSP
usage may be reduced during dynamic bypassing, but the possibility of
glitching during playback is increased.
Note:
Changes to this setting do not take effect until all open sessions con-
taining UAD plug-ins are reloaded.

Force Logic to use “live mode” for tracks with UAD plug-ins
When UAD plug-ins and Logic 7.2.1 (and higher) are used together and this
setting is checked, all Logic tracks with UAD plug-ins are forced into Logic's
“live mode” and latency is reduced. Reduced latency is useful for tracking
when Logic's Software Monitoring feature is active.
Note:
Logic's “live mode” is unrelated to UAD-2's LiveTrack Mode.
When this setting is active, UAD-2 latency is the same as the hardware I/O
buffer. In Logic versions prior to 7.2.1 (and later versions when live mode is
disabled), UAD latency is determined by the larger of the audio interface
hardware I/O buffer size and the Process Buffer Range setting within Logic.
When Logic’s “live mode” is NOT active and this setting is NOT enabled, the
minimum Process Buffer Range setting (“Small”) in Logic 7 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
only).
On multi-processor machines 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 con-
taining UAD plug-ins are reloaded.
