Reverb And Early Reflections; 100: Overb - Korg NAUTILUS Series Parameter Manual

Reverb and Early Reflections

100: Overb

The Overb features a high-quality, diffusion-based reverb
core. In addition to setting the size of the room, you can
model its shape and materials by adjusting the diffusion
characteristics of both the initial reflections and the main
reverberant wash, and via separate controls for the high, mid,
and low decay times. The Overb also includes
randomization, for richer and smoother reverb timbres.

Pre EQ
There are two fully parametric bands of peaking EQ, for
adjusting the reverb timbre. These affect only the reverb, and
not the dry signal. Both bands have identical parameters.
Trim
Sets the EQ input level.
Band 1
Band1
Switches the first band of EQ band on and off.
Fc [Hz]
Sets the center frequency of Band 1.
Q
Sets the bandwidth of Band 1.
Gain [dB]
Sets the gain of Band 1.
Band 2
Band 2 has the same parameters as Band 1, above.
Rolloff
Rolloff
This controls a lowpass filter on the output of the effect.
Settings around 6-8kHz are good for producing a warm,
smooth sound.
REVERB
Pre Delay [msec]
Sets the delay time from the dry sound.
Diffusion1
Diffusion 1 and 2 soften the sound before it enters the reverb
core, shaping the timbre of the initial reflections. Setting
both diffusers to around 50 generally produces sufficient
diffusion for smooth reverbs; extremely high levels may
cause ringing.
Some source material, such as vocals, may also benefit from
lower settings of diffusion, allowing for more discrete
echoes.
Wet / Dry
Diffusion1 and Diffusion2 differ in how the reflections are
spaced, and the balance between these two parameters will
Reverb
vary the character of the reverb.
Diffusion2
Wet / Dry
This is the second diffuser for the initial reflections. For
more information, see "Diffusion1," above.
Size
Sets the size of the space.
Time
This sets the main reverberation time. The Damping and
(bass) Gain parameters, below, let you adjust the decay
[0...100]
times separately for the high and low frequencies,
respectively.
Diffusion
This sets the density of reflections within the main reverb.
[Check-box]
Low settings will produce more discrete echoes, and high
settings will produce a smoother reverb. Extremely high
settings may cause ringing.

Damping
This sets the cutoff of the high-frequency damping filter. If
Damping is set to 100, the high frequencies will decay at the
same rate as the low frequencies; at 0, the high frequencies
will decay almost instantly.
