5.6 effect parameters
Please note that per preset,a maximum of 16 parameters can be controlled on
the Vistonics user interface. Some of the original Lexicon effects have more
than 16 parameters, in this case STUDER has made the choice of the 16 most
important parameters - which then can be controlled.
On/Off :
Switches the effect processing On and Off.
Mix :
Allows to blend the unprocessed signal with the processed effect signal. Range
[0 .. 100] %
These two parameters are available for all effect presets.

Halls, plates and chambers
For the categories
Halls, Plates and Chambers
the following parameters are available :
Predelay
: This is a delay that is added to the diffused signal before it enters the main
part of the reverb. For all intents, it may be considered as delay that is added
to the reverberated signal. It is used to temporally separate the reverb from
the dry signal. Range [0 .. 1000] ms.
Reverb Time :
This is the reverb decay time. The range is depending on the Room Size
parameter. Range [0.11 .. 210] s.
Reverb Out Frequency :
The late reverb signal is filtered by a one pole low-pass. This is the filters
cutoff frequency. Range [50 .. 20’000] Hz.
Front Reverb Frequency :
The front portion of the late reverb signal is filtered by a one pole low-pass.
This is the filters cutoff frequency. Range [50 .. 20’000] Hz.
On surround
engines only.
Back Reverb Frequency :
The back portion of the late reverb signal is filtered by a one pole low-pass.
This is the filters cutoff frequency. Range [50 .. 20’000] Hz.
On surround
engines only.
Center Reverb Frequency :
The center portion of the late reverb signal is filtered by a one pole low-pass.
This is the filters cutoff frequency. Range [50 .. 20’000] Hz.
On surround
engines only.
Diffusion :
Input diffusion is the first part of processing for any signal entering a reverb.
It can be described as a smearing or softening of the signal and is typically
used to lessen the impact of strong transients. Range [0 .. 100] %.
Reverb Time HiCut :
This parameter, also known as Hicut or RTHC is a low-pass filter in the
recirculating part of the reverb. It represents a frequency above which the tail
dies away more quickly. In some ways, it represents the opposite end of the
scale from BassRT, and may be considered an analog of air absorption. It is
also closely tied to the Hi Cut Damping parameter. Range [50 .. 20’000] Hz.
