This controls the amount of reßective material that is in the space being
emulated, much like an acoustical absorption coefÞcient. The lower the setting,
the longer it will take for the sound to die away. A setting of 0% will cause an
inÞnite decay time.
Adjusts the basic decay time of the late portion of the reverb.
Adjusts the basic decay time of the late portion of the reverb after diffusion.
This controls the amount of high frequency energy that is absorbed as the
reverb decays. The values set the cutoff frequency of the 1 pole (6dB/oct) lopass
Þlter within the reverb feedback loop.
These control the amount that each channel of the reverb is delayed relative to
the dry signal. Setting different lengths for both channels can de-correlate the
center portion of the reverb image and make it seem wider. This only affects the
late reverb in algorithms that have early reßections.
Controls the cutoff frequency of a 1 pole (6dB/oct) lopass Þlter at the output of
the reverb. This only affects the late reverb in algorithms that have early
reßections.
Adjusts the mix level of the early reßection portion of algorithms offering early
reßections.
Adjusts the mix level of the late reverb portion of algorithms offering early
reßections.
This parameter selects the basic type of reverb being emulated, and should be
your starting point when creating your own reverb presets. Due to the inherent
complexity of reverb algorithms and the sheer number of variables responsible
for their character, the Room Type parameter provides condensed preset
collections of these variables. Each Room Type preset has been painstakingly
selected by Kurzweil engineers to provide the best sounding collection of
mutually complementary variables modelling an assortment of reverb families.
When a room type is selected, an entire incorporated set of delay lengths and
diffusion settings are established within the algorithm. By using the Size Scale,
DiffAmtScl, DiffLenScl, and Inj Spread parameters, you may scale individual
elements away from their preset value. When set to 1.00x, each of these
