Lo Decay
Range: 0.5 to 2.0
Use the Lo Decay parameter to define the decay
time for the lower frequencies of the reverb. This
parameter acts as a multiplier to the Lo Mult.
and Lo Mid Mult. parameters in the Reverb Color
section on the Rev page.
Example:
►
Let us assume the Decay parameter on the
Grid page is set to 2.0 seconds – this is the
“base” decay time.
►
On the Rev page, you have set the Low Mult.
parameter to 1.5.
This means that the decay time for the low
frequency band (as defined by the Lo X Over
parameter) is (2 x 1.5 =) 3.0seconds.
►
You have also set Lo Mid Mult. on the Rev
page to 2.5.
Accordingly, the decay time for the low mid
frequency band is now (2 x 2.5 =) 5.0seconds.
►
Now if you set Lo Decay on the Grid page to
2 and move the green dot all the way towards
one channel in the grid, this will have the fol-
lowing effect for this particular channel:
►
Decay for the low frequency band:
(2 x 1.5 x 2 =) 6seconds.
►
Decay for the low-mids frequency band:
(2 x 2.5 x 2 =) 10seconds.
Put more simply: The parameters on the Rev
page set the basic character of the reverb, allow-
ing you to use the Grid as a wider “paint brush”
for customizing/weighing the base settings as
required.
Hi Decay
Range: 0.5 to 2.0
Use the Hi Decay parameter to define the de-
cay time for the higher frequencies of the reverb.
This parameter acts as a multiplier to the Hi Mid
Mult. and Hi Mult. parameters in the Reverb Col-
or section on the Rev page.
The interaction between the four involved pa-
rameters (Decay and Hi Decay on the Grid page,
Hi Mid Mult. and Hi Mult. on the Rev page) is
the same as for the low and low mid frequency
bands described in the example for the Lo Decay
parameter above.
Tip:
When you are creating new Reverb8 presets, be
sure to start by setting the Lo Decay and Hi De-
cay parameters to “1” first. This way, you enjoy
the greatest flexibility when you edit and “play”
your Reverb Preset later using the Grid.
Hi Cut
Range: 20 Hz to 20 kHz
Use the Hi cut parameter to define the cutoff
frequency for the high-cut filter applied to the
reverb. The filter frequencies applied to all eight
Reverb channels as defined by the position of
the green dot on the Grid page refer to the set-
ting of this parameter.
