Logic Pro ChromaVerb main window controls
The main window contains the most commonly used parameters and shows a Damping EQ
overlay in the graphic display.
The details window contains advanced parameters and shows the built-in six band Output
EQ. Click the Main or Details buttons at the upper right to switch between windows.
ChromaVerb main window control parameters
Attack knob and field: Set the attack phase of the reverb. This affects either the volume
or the density build-up time, depending on the chosen room type.
For the following room types the Attack parameter increases volume over time:
Theatre, Dense Room, Smooth Space, Reflective Hall, Strange Room, Airy.
For the following room types the Attack parameter sets the amount of time it takes
for the reverb to reach the maximum density value, determined with the Density knob:
Room, Chamber, Concert Hall, Synth Hall, Digital, Dark Room, Vocal Hall, Bloomy.
Size knob and field: Determine the dimensions of the room. Higher values correspond to
a larger space.
Density knob and field: Adjust the density of the early and late reflections
simultaneously, depending on room type.
Predelay field: Set the time between the start of the original signal and the arrival of
the early reflections. A short predelay setting tends to push sounds away and longer
predelay settings tend to bring sounds more to the forefront.
An extremely short predelay setting can color the sound and make it difficult to pinpoint
the position of the signal source. A very long predelay setting can be perceived as an
unnatural echo and can divorce the original signal from its early reflections, leaving
an audible gap between them. An optimal predelay setting depends on the type of
input signal—or more precisely, the envelope of the input signal. Percussive signals
generally require shorter predelays than signals where the attack fades in gradually.
A good working method is to use the longest possible Predelay value before you start
to hear side effects, such as an audible echo. When you reach this point, reduce the
Predelay setting slightly.
Predelay sync button: Turn on to restrict Predelay values to divisions synchronized
with the host application tempo.
Decay knob and field: Set the decay time. The decay for certain frequencies is
dependent on damping parameter values.
Decay sync button: Turn on to restrict Decay values to divisions synchronized with the
host application tempo.
Freeze button: Turn on to recirculate the signal infinitely inside the chosen room type.
Distance knob and field: Set the perceived distance from the source by altering early
and late energy.
Dry/Wet sliders and fields: Independently set the levels of the source and effect signals.
