Grid setup – Res. parameters
What happens when the dot in the Grid is moved
off-center is defined on the Setup page of the
Reverb8 algorithm – see “Reverb 8 algorithm –
Setup page” (page 39).
With the Decay Res. parameter on the Setup
page set to the “Default” setting, the decay time
of channel 8 in Fig8 would be much longer than
the rest, channel 5 and 7 somewhat longer, and
channel 3 and 6 a bit longer. For a more detailed
explanation, see the following section.
A setting of 50% for the Decay Res. parameter
means that moving the dot from the center to-
wards a channel will prolong the previously set
Reverb Decay time by 50%.
Grid setup – Focus parameters
The Focus parameters for the Decay, Lo Decay,
Hi Decay and Hi Cut parameters on the Setup
page determine how strongly neighboring chan-
nels are affected when the dot is moved toward
one channel.
►
Narrow setting: There is only a limited influ-
ence on the neighboring channel(s).
►
Default: The neighbor channels are influ-
enced, and a bit of influence is also applied to
their next neighbor.
►
Wide: Similar to Default, but the effect on the
respective channels is more pronounced.

Focus may also be set to…
►
“FB Only” (“Front/Back only”) or
►
“LR Only”. (“Left/Right only”).
Those settings provide the same off-center
adjustments to all channels in either the Front/
Back or the Left/Right plane.
Resolution and Focus settings may be
changed before or after adjusting the Grid.
For example, with the scenario shown in Fig 8,
if Decay Res. were changed to -75%, the decay
in channels 8, 5 and 7 (direct neighbors), 6 and
3 (neighbors’ neighbors) would become much
shorter than the remaining channels.
