Specifications

Bypass (7)
It's a global bypass.
Channel Processing Selector (8)
When operating on a multi-channel bus, all channels are processed by default, but it can be useful to remove some channels
from the processing for some reasons. This selector allows to keep the unchecked channels untouched.
This feature may be used if different settings are required. Several instancies of a plug-in can be used in series, each one
processing a particular channel with its own settings.
Channel Side Chain Routing (9)
When operating on a multi-channel bus, all channels are feeding the side chain by default, but it can be useful to prevent
some channels feeding the side chain for some reasons. Note also that the external side chain (EX), when activated,
disables the internal side chain.
Here are the different behaviors for external side chain depending of the host applications:
•
Audio Unit
in Live and Logic > The EX button is enabled by default even if no side chain buss is specified in the plug-in
handler. All channels are summed and applied as external side chain automatically by the host application. This EX
button must be disabled if the internal side chain management of the plug-in is preferred because it isn't phase sensitive.
•
RTAS
> The EX button is only active if a side chain buss is selected from the plug-in handler. To use the internal side
chain of the plug -in no external side chain must be selected.
•
VST
> The external side chain bus must be routed as a particular channel of the mixer slice on which the plug-in is
inserted (processing a stereo signal requires 3 channels). Then, from the plug-in interface, this particular must be
selected as side chain source. The EX button never appears. This allows to mix both internal and external signals for side
chain.
MS Width Control (10)
Unit: dB - Value Range: -6 / +6 - Step: 0.01
Default Value: 0
Sets the stereo width of the processed signal. A -6 dB value deceases the stereo width. A +6 dB value increases the
wideness of the stereo mix but can produce phase issue.
MS Mode On/Off (11)
Default Value: Off
Enables one MS encoding matrix at the input and one MS decoding matrix at the output of the dynamic processing in order
to control the stereo width of the mix. When engaged, the side chain is fed by a MS encoded signal that is reflected in the
display section. M channel corresponds to the normal left channel. And the S channel corresponds to the normal right
channel This feature is only available when two channels (no more, no less) are processed.
Link (12)
Default: Enabled
By default the maximum value issued from all channels feeding the side chain is retained as source for processing.
This manner, the space information is kept for the processed multi-channel signals.
When disabled, every channel uses its own value for individual processing.
This configuration may be used in conjunction with the MS width section which encode the signal in MS before processing,
