101: Reverb Hall; 102: Reverb Smooth Hall; 103: Reverb Wet Plate; 104: Reverb Dry Plate - Korg NAUTILUS Series Parameter Manual

In real acoustic spaces, high frequencies generally delay
somewhat faster than low frequencies, so moderate amounts
of damping will create a more realistic sound.
Bass Crossover [Hz]
Sets the crossover frequency for the Bass Gain.
Gain [dB]
This lets you tailor the decay time of the reverb's low
frequencies, using the frequency set by the Bass Xover.
Negative settings make the low frequencies decay faster than
the main reverb; positive settings make them decay more
slowly.

101: Reverb Hall

This hall-type reverb simulates the reverberation of mid-size
concert halls or ensemble halls. For detailed explanations of
the parameters, see "104: Reverb Dry Plate," below.

102: Reverb Smooth Hall

This hall-type reverb simulates the reverberation of larger
halls and stadiums, and creates a smooth release. For
detailed explanations of the parameters, see "104: Reverb
Dry Plate," below.

103: Reverb Wet Plate

This plate reverb creates warm, dense reverberation. For
detailed explanations of the parameters, see "104: Reverb
Dry Plate," below.

104: Reverb Dry Plate

This plate reverb creates dry, light reverberation.
Wet: Mono In - Stereo Out / Dry: Stereo In - Stereo Out

MODULATION
Rate
The O-Verb includes randomization in the reverberant wash,
to diminish resonant peaks and add a rich character to the
sound. The Rate determines the speed of the randomization.
Depth
This determines the intensity of the randomization.
OUTPUT
This is the standard effects output section, with modulatable
control over wet/dry balance. For more information, see
"OUTPUT" on page 762.
HEQ Fc
Selects the cutoff frequency (high or mid-high) of the high-
range equalizer.
Wet / Dry
HEQ Gain [dB]
Sets the gain of the High EQ.
REVERB
Wet / Dry
Reverb Time [sec]
Sets the reverberation time.
High Damp [%]
Sets the amount of high-frequency attenuation.
Pre Delay [msec]
The Pre Delay is not heard directly; it only affects the signal
going to the reverb. Higher amounts of Pre Delay enhance
the feeling of spaciousness, allowing the reverb to blossom a
little after the initial sound.
