vanced
beats (e.g. 1/4 triplets, 1/4 dotted notes) for the left and right
delays.
Time L/R
These parameters are used to display the exact delay time and to
allow editing with all Source settings. You may set from 0 to
2500ms (2.5 seconds) of delay for the left and right delay lines.
Feedback L/R
Re-introduces a portion of the audio output signal of the Delay
block back to the input to add echo repeats.
Hi Cut / Low Cut
These steep highpass (Low Cut) and low pass (Hi Cut) filters
control the bandwidth of the delays. Applying these filters to the
delays can create the feeling of space while not obscuring the
main vocal signal.
Duck Amount
This sets how much attenuation (gain reduction) is applied to
the delayed signal when a vocal is present. For ducking to not be
too obvious, a slight reduction of -6 dB is best. The Ducking can
also be turned Off with this parameter.
Lead Level
Level of the Lead voice mixed with the effect.
Voice Processor Preset: Reverb
Reverb is arguably the most common vocal effect. It can add a
spaciousness that softens the abrupt beginnings and endings of
lyric phrases. Many reverb types are meant to imitate the natural
sound of spaces like churches, clubs and halls but not all. Some
reverb effects are recreations of electro-mechanical effects meant
to imitate real spaces like plates and springs.
Reverbs are made up of early reflections and the longer reverber-
ant sounds known as the tails.There are usually controls to con-
trol the balance of room level and tail. Additionally, a small delay
can be added between the dry voice and the reverb signal that
adds clarity by briefly separating the dry voice from its reverb.
By far the most important control for reverb is the level. A single
reverb patch can have a different result for the audience whether
it is mixed quietly or boldly in the mix.
(Reverb) On/Off
This button allows enabling/disabling of the Reverb block. It is
the same control found in the “Easy Preset” page.
Set
Use the soft knob assigned to this parameter to choose a pre-
programmed reverb style you like. This corresponds to the
option selected in the “Easy Preset” page.
Level
Sets the mix level for the Reverb effect.
Decay
Sets the length of the reverb tail from 10mS to 20 seconds. Note
that, due to the complex nature of Reverb algorithms, a decay
time of 4 seconds may sound quiet different from one style to the
next, even when the rest of the settings are identical.
Pre Delay
Pre Delay introduces a short (up to 100 ms) delay between the
dry audio signal and the onset of reverb to help simulate larger
spaces and to provide audio separation between the dry signal
and the reverb effect.
Hi Color / Lo Color
These are preset-frequency filters inserted into the Reverb feed-
back path that tailor the low and high frequency response and
decay of the tails.Values toward -50 will cut response in its
respective band and a values toward 50 increase response.
Duck Amount
When Ducking has a value other than Off, the Reverb block’s
output will be reduced while you are singing. At the end of a
sung phrase, the effects return to the level you set, increasing the
clarity of your vocals while still sounding very “wet”. This
parameter sets the amount of attenuation for Ducking.
Lead Level
Level of the Lead voice mixed with the effect.
