Algorithm Reference-20
Adjusts the detuning depth in cents caused by a moving reverb delay line. Moving delay
lines can imitate voluminous ßowing air currents and reduce unwanted artifacts like
ringing and ßutter when used properly. Depth settings under 1.5ct with LFO Rate
settings under 1.00Hz are recommended for modeling real spaces. High depth settings
can create chorusing qualities, which wonÕt be suitable for real acoustic spaces, but can
nonetheless create interesting effects. Instruments that have little or 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).
Adjusts the rate at which the moving reverb delay lines move.
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.
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.
This adjusts the cutoff frequency of a 1 pole (6dB/oct) lowpass Þlter applied to the signal
being injected into the body of the reverb.
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.
Adjusts the amount of diffusion applied to the early reßection network.
Adjusts the length of diffusion applied to the early reßection network. This is inßuenced
by E PreDlyL and E PreDlyR.
Scales the delay lengths inherent in the early reßection network.
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.
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.
This adjusts the cutoff frequency of a 1-pole (6dB/oct) lowpass Þlter applied to the early
reßection feedback signal.
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.
Adjusts the left and right early reßection delays fed to the same output channels.
Adjusts the left and right early reßection delays fed to the opposite output channels.
Adjusts the diffusion delays of the diffusers on delay taps fed to the same output
channels.
channels.
Adjusts the balance between early reßection delay tap signals with diffusers fed to their
same output channel, and those fed to opposite channels. 0% allows only 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.
