Global output parameters
X-Over slider and field: The X-Over slider sets the crossover frequency. Any impulse
response frequency that falls below this value is affected by the Lo Spread knob.
Frequencies above are affected by the Hi Spread knob. See Use Space Designer
output controls in Logic Pro.
Lo/Hi Spread knobs and fields: The Spread knobs set the perceived width of the stereo
field.
Note: A single Spread knob is shown in Synthesized IR mode of surround instances
and affects the perceived width of the overall surround image.
LFE to Rev slider: Set the output level of the LFE channel independently of other
surround channels.
C(enter) slider: Set the output level of the center channel independently of other
surround channels.
Bal(ance) slider: Set the level balance between the front (L-C-R) and rear (Ls-Rs)
channels.
In 7.1 ITU surround, the balance pivots around the Lm-Rm speakers, taking the
surround angles into account.
In 7.1 SDDS surround, the Lc-Rc speakers are considered front speakers.
Dry/Wet sliders: Set output levels for the dry (source) and wet (effect) signal.
Use Space Designer global controls in Logic Pro
Space Designer global parameters affect the overall input, output, or behavior of the
plug-in. See Logic Pro
Space Designer global parameters and Use Space Designer
output controls in Logic Pro.
The tasks below cover the use of Space Designer global parameters.
Use the Space Designer Input slider
The Input slider works only in stereo channel configurations. It is not shown in mono or
surround channels.
In Logic Pro, drag the Input slider to determine how a stereo signal is processed.
Stereo setting (top of slider): The signal is processed on both channels, retaining
the stereo balance of the original signal.
Mono setting (middle of slider): The signal is processed in mono.
XStereo setting (bottom of slider): The signal is inverted, with processing for the
right channel occurring on the left, and vice versa.
In-between positions: A mixture of stereo to mono crossfeed signals is produced.
