• Action menu: Choose a menu command.
• Reset Selected Envelope: Reset the currently displayed envelope to default values.
• Reset All Envelopes: Reset all envelopes to default values.
• Reset EQ: Reset the Output EQ to default values.
• Latency Compensation: Enable or disable the internal latency compensation
feature. When active, the direct signal in the output section is delayed to match
the processing delay of the effect signal.
The complex calculations made by Space Designer take a small amount of time,
which results in a processing delay, or latency, between the direct input signal and
the processed output signal. Space Designer processing latency increases if Low or
Lo-Fi is chosen in the Quality pop-up menu. Processing latency does not increase in
surround mode or at sample rates above 44.1 kHz (Medium or High Quality pop-up
menu settings).
Note: This compensation feature is not related to latency compensation in Logic Pro;
it occurs entirely within Space Designer.
• Volume Compensation: Disable or enable the internal impulse response volume
matching function.
The reverb volume compensation feature attempts to match the perceived—not the
actual—volume differences between impulse response files. It should generally be
left on, although it may not work with all types of impulse responses. If you have
an impulse response that is of a different level, turn off volume compensation, then
adjust input and output levels accordingly.
• Show Bezier Handles: Enable or disable envelope curve handles (nodes) in the main
display. These enable you to precisely reshape envelopes. See

envelopes in Logic Pro.
• Predelay sync button: Turn on to restrict Predelay knob values to divisions synchronized
with the project tempo.
• Predelay knob and field: Set the reverb predelay time, or time between the original
signal and the first reflections from the reverb. See Use Space Designer global
controls in Logic Pro.
• Length knob and field: Adjust the length of the impulse response. This control works in
conjunction with the Size knob.
• Size knob and field: Adjust the sample rate of the loaded impulse response file, thereby
changing the perceived size of the reverb by widening or narrowing the room. Size can
also be used to preserve the original length of the impulse response when changing the
sample rate with the Quality pop-up menu.
The Size knob value has an impact on the decay because it is multiplied with the Length
knob value. To explain, a Length knob value of 100% and a Size knob value of 100%
result in a decay that is the full length of the loaded impulse response.
• Refl Shape knob and field: Adjust to change the perceived shape of the room in
surround instances. This control alters the spacing of early reflections.
