if delayed, and thus you can get by with a dryer mix while maintaining the same
subjective wet/dry level.
Room Type The con fi guration of the reverb algorithm to simulate a wide array of carefully designed
room types and sizes. This parameter effectively allows you to have several different
reverb algorithms only a parameter change away. Smaller Room Types will sound best
with shorter Rvrb Times, and vice versa. (Note that since this parameter changes the
structure of the reverb algorithm, you may not modulate it.)
Diff Scale A multiplier which affects the diffusion of the reverb. At 1.00x, the diffusion will be the
normal, carefully adjusted amount for the current Room Type. Altering this parameter
will change the diffusion from the preset amount.
Size Scale A multiplier which changes the size of the current room. At 1.00x, the room will be the
normal, carefully tweaked size of the current Room Type. Altering this parameter will
change the size of the room, and thus will cause a subtle coloration of the reverb (since the
room’s dimensions are changing).
Density A multiplier which affects the density of the reverb. At 1.00x, the room density will be the
normal, carefully set amount for the current Room Type. Altering this parameter will
change the density of the reverb, which may color the room slightly.
Gate Thres The input signal level in dB required to open the gate (or close the gate if Gate Duck is on).
Gate Duck When set to “Off”, the gate opens when the signal rises above threshold and closes when
the gate time expires. When set to “On”, the gate closes when the signal rises above
threshold and opens when the gate time expires.
Gate Time The time in seconds that the gate will stay fully on after the signal envelope rises above
threshold. The gate timer is started or restarted whenever the signal envelope rises above
threshold. If Retrigger is On, the gate timer is continually reset while the side chain signal
is above the threshold.
Gate Atk The attack time for the gate to ramp from closed to open (reverse if Gate Duck is on) after
the signal rises above threshold.
Gate Rel The release time for the gate to ramp from open to closed (reverse if Gate Duck is on) after
the gate timer has elapsed.
Signal Dly The delay in milliseconds (ms) of the reverb signal relative to the side chain signal. By
delaying the reverb signal, the gate can be opened before the reverb signal rises above the
gating threshold.
