modeling real spaces. High depth settings can create chorusing qualities, which
wonÕt be unsuitable for real acoustic spaces, but can nonetheless create
interesting effects. Instruments that have little if no inherent pitch ßuctuation
(like piano) are much more sensitive to this LFO than instruments that normally
have a lot of vibrato (like voice) or non-pitched instruments (like snare drum).
Inj Build Used in conjunction with Inj Spread, this adjusts the envelope of the onset of the
reverb. SpeciÞcally, it tapers the amplitudes of a series of delayed signals
injected into the body of the reverb. Values above 0% will produce a faster
build, while values below 0% will cause the build to be more gradual.
Inj Spread Used in conjunction with Inj Build, this scales the length of the series of delays
injected into the body of the reverb. For a true representation of the selected
Room Type injector spread, set this to 1.00x.
Inj LP This adjusts the cutoff frequency of a 1 pole (6dB/oct) lopass Þlter applied to
the signal being injected into the body of the reverb.
Inj Skew Adjusts the amount of delay applied to either the left or right channel of the
reverb injector. Positive values delay the right channel while negative values
delay the left channel.
E DiffAmt Adjusts the amount of diffusion applied to the early reßection network.
E DfLenScl Adjusts the length of diffusion applied to the early reßection network. This is
inßuenced by E PreDlyL and E PreDlyR.
E Dly Scl Scales the delay lengths inherent in the early reßection network.
E Build Adjusts the envelope of the onset of the early reßections. Values above 0% will
create a faster attack while values below 0% will create a slower attack.
E Fdbk Amt Adjusts the amount of the output of an early reßection portion that is fed back
into the input of the opposite channel in front of the early pre-delays. Overall, it
lengthens the decay rate of the early reßection network. Negative values
polarity invert the feedback signal.
E HF Damp This adjusts the cutoff frequency of a 1 pole (6dB/oct) lopass Þlter applied to
the early reßection feedback signal.
E PreDlyL, E PreDlyR Adjusts how much the early reßections are delayed relative to the dry signal.
These are independent of the late reverb predelay times, but will inßuence E
Dly Scl.
E Dly L, E Dly R Adjusts the left and right early reßection delays fed to the same output
channels.
E Dly LX, E Dly RX Adjusts the left and right early reßection delays fed to the opposite output
channels.
E DifDlyL, E DifDlyR Adjusts the diffusion delays of the diffusers on delay taps fed to the same
output channels.
E DifDlyLX, E DifDlyRX Adjusts the diffusion delays of the diffusers on delay taps fed to the opposite
output channels.
E X Blend Adjusts the balance between early reßection delay tap signals with diffusers fed
to their same output channel, and those fed to opposite channels. 0% will only
allow delay taps being fed to opposite output channels to be heard, while 100%
allows only delay taps going to the same channels to be heard.
