Mixing
VST configuration
• Force stereo operation. If you need to use mono plug-ins in situations that requires stereo,
you can enable this option to run the plug-ins in stereo mode. This option simply creates two
identical output streams from the plug-ins where only one existed.
• Do not intercept NRPNs. SONAR uses NRPNs to run automation of your VST plug-ins.
However, some instruments have their own implementation of this process, so checking this
box passes the NRPNs directly to the instrument, allowing it to manage its own automation.
• Max used inputs. This option controls the number of sidechain inputs that are exposed by
SONAR for the plug-in. The default value is the maximum number of input channels that are
exposed by the plug-in. If the value is set to 2, SONAR will not display any sidechainable
inputs; if set to 4, SONAR will display 1 sidechainable input, etc.
• Load using jBridge wrapper. This check box is only enabled on systems where jBridge is
installed. jBridge allows you to use 32-bit VST effects and instruments when using the x64
version of SONAR, as well as use 64-bit plug-ins when using the x86 version of SONAR.
jBridge can also bridge 32-bit plug-ins in the x86 version of SONAR, allowing your computer to
overcome the memory limitations of a single 32bit process.
• Enable delay compensation. Usually, you will leave this check box the way you found it.
SONAR contains a delay compensator, which turns on and off automatically for each individual
plug-in (only a few plug-ins need it). If your plug-in needs extra time to process the audio data,
the plug-in sends a message to SONAR, so it can synchronize playback time to the delayed
output from the plug-in.
• Serialize Host Access. When Serialize Host Access is selected, communications with the
plug-in are serialized as far as possible. The default behavior is OFF, which allows
asynchronous calls to the plug-in.
When Serialize Host Access is disabled, SONAR’s audio engine runs more efficiently and
allows the UI thread to interact independently with the plug-in GUI without impacting the audio
engine.
The only reason to enable Serialize Host Access would be for a plug-in that has thread safety
problems leading to crashes or glitches when changing plug-in presets.
• Enable mono processing. When enabled, this option replicates the audio signal from the
first channel to the left and right channel, effectively forcing the output of VST to be mono.
• Translate Bank/Program Changes. When enabled, this option translates MIDI program
change messages into VST preset changes. This is only used for plug-ins that do not support
MIDI program change messages.
• Always suspend on stop. When enabled the VST plug-in state will be set to suspended
when the transport is stopped in SONAR. The default behavior is to keep VST’s always in a
resumed state. Enabling this option will prevent effects tails from being heard when the
transport is stopped.
