Reverberation Block
This block can be divided into four sub-blocks, REVC, REVS,
REV17 and REV2.
These four blocks process signals received from the
Pre-effect block and then send them to the Post-effect
block. According to the algorithm type used, the signals from
the Pre-effect block are processed through different sub-
blocks.
When editing a preset memory, examine which algorithm is
used in the preset memory.
Parameters also vary as the algorithm type changes.
Stereo-in/stereo-out (ST-ST) type and
monaural-in/stereo-out (MONO-ST) type
Algorithm used in the Reverberation block can be
characterized into two types; stereo-in/stereo-out (ST-ST)
type and monaural-in/stereo-out (MONO-ST) type.
The ST-ST type is used for a stereo-processing of signals of
ch1 and ch2 while the MONO-ST type gives different effects
to signals of chi and ch2. Since these two types have their
own signal processing configuration, signals pass through
different sub-blocks according to the algorithm type used.

Concerning Parameters
Algorithms contains several parameters. After being familiar
with them, you will be able to create any effect exactly as
you imagine.
Note:
When editing the Reverberation block, keep the balance of direct
sound (DRY control) and effect sound (EFFECT control).
Unbalanced adjustment may cause insufficiency in the resulting
effect.
Reverberation Parameters
Predelay
Time lag between the direct sound and the reverberation
(primary reverberating sound) and the volume (level) of the
reverberating sound are user adjustable. Normally the delay
time is set to “sync”.
To be continued
2nd predelay
Time lag between the direct sound and slightly more coarse
reverberation than the primary reverberation and its volume
are user adjustable. Combining this with the predelay
parameter will give nuances fine of reverberation.
Cross predelay
Predelay to be output from the predelay box of the opposite
channel.
This should be sufficiently delayed more than the predelay.
2nd cross predelay
2nd predelay to be output from the predelay box of the
opposite channel.
Early refiection
Initial reflecting sound to be output from the predelay box.
2nd early reflection
Initial reflecting sound with brief reverberation.
Cross early reflection
Initial reflecting sound to be output from the predelay box of
the opposite channel.
Rotate high, rotate bass, rotate treble
Filters used to change the reverberation time specific to the
frequency band. Raising the level too high may cause
oscillation.
Spread
Represents the feeling of spreading reverberation. The
larger the value becomes, the more reverberation feeling
spreads.
Normally the value is set to the same as that of the size
parameter.
Size
Represents the time scale of the box which is the most
meaningful in each algorithm.
This parameter controls the size of sound field without
changing features of the effect.
