Sonar

Compatibility

Mode

(Windows)

Click the Sonar Compatibility Mode checkbox to improve UAD Powered Plug-

Ins performance when used with Cakewalk Sonar. This mode should be dis-

abled when using different hosts, otherwise audio degradation could occur.

Misc Settings

(Mac OS)

Release all DSP resources on AudioUnit bypass

Some Audio Unit hosts dynamically bypass plugins when they are not being

used during playback, for example when no audio is present at the current

playback position. As of version 3.9.0, UAD plugins are no longer un-

loaded/reloaded each time the host performs this dynamic bypass. Instead,

the UAD plugins stay loaded on the card, which reduces playback glitches.

Checking the “Release all DSP resources on AudioUnit bypass” option will un-

load UAD plugins from the card 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: This setting affects the Mac OS X Audio Units platform only.

Force Logic Live Mode

When UAD v4.3.0 (and higher) and Logic 7.2.1 (and higher) are used to-

gether and this setting is checked, all Logic tracks with UAD plugins are

forced into "Live Mode" and latency is reduced. Reduced latency is useful for

tracking when Logic's Software Monitoring feature is active.

When Live Mode is active, UAD latency is twice the hardware I/O buffer

size. In Logic versions prior to 7.2.1 (and later versions when live mode is dis-

abled), UAD latency is determined by the larger of the hardware I/O buffer

size and the Process Buffer Range setting within Logic. Since the minimum Pro-

cess Buffer Range setting ("Small") in Logic 7 corresponds to 512 samples,

this means the minimum possible UAD latency is 1024 samples (the current la-

tency is displayed in the UAD Meter System Information window) when Live

Mode is inactive.

Note: On dual processor machines Live Mode forces all plugins on tracks

with UAD plugins (and any aux/busses fed by those tracks) to run on one pro-

cessor only. To allow host plugins to run on both processors under these con-

ditions, deactivate this setting.
