Feedback Controls feedback amount. Higher
feedback settings produce more intense chorus-
ing.
Shape Selects the waveshape for the Chorus
LFO. Choices are sine, triangle, sawtooth,
square, sample & hold, or sample & glide. Each
produces a unique detuning effect.
Delay/Reverb
Use the controls in this section to set the char-
acter and amount of delay and reverb. Delay and
reverb can be used to add a sense of space and
depth to a sound. You can also use delay and re-
verb to convert a mono patch to stereo.
All Virus Indigo plug-ins sharing the same DSP
(Virus Indigo 1a, 1b, 1c, and so on) also share a
single delay. The plug-in designated as the “de-
lay master” carries the delay signal. All other
plug-ins sharing the same DSP automatically
bus their delay sends to the delay master.
For a plug-in to be designated as the delay mas-
ter, its Effect button must be enabled (on the FX-
1 page).
Mode Selects the type of effect (reverb or delay)
used. Selecting one of the delay patterns pro-
duces a left channel-to-right channel rhythmic
ping-pong delay that modifies the currently set
delay time according to the given ratio.
An X+Y pattern selects a ping-pong delay where
the delay times are locked into sync with the
master clock. The Clock parameter sets the delay
tempo (not the Time parameter). The two num-
bers represent note increments and indicate the
delay for the left and right channels. Setting the
delay Clock parameter to sixteenth notes and se-
lecting 2+1 as the Mode, for example, produces a
ping-pong delay with a left channel delay of two
16 notes and right channel delay of one 16th
note. Used with the Feedback parameter, these
groove-oriented algorithms produce interesting
rhythmic patterns and accents, particularly in
conjunction with the arpeggiator. Feedback is
generated using the left channel delay tap.
An X:Y pattern selects a ping-pong delay where
the left and right channels have a numeric ratio.
Selecting 2:1, for example, selects a ping-pong
delay with a left channel delay that is two times
as long as the right. Use the Time parameter to
set the longer channel of the ping-pong delay.
Feedback is generated using the longer channel
of the delay.
Send Controls the balance between the dry
source signal and the delay effect. Signal level is
determined by Patch Volume (Oscillator page),
making this a post-fader control. Set from 0–99,
it functions as a send level control. Set from
100–127, it acts as a direct/effect control. At 127,
the signal is 100% wet.
Effect Selects the plug-in as the master delay
control. The plug-in designated as the delay
master controls all delay parameters—with the
exception of Delay Send level—for all other
plug-ins sharing the same DSP.
Only one plug-in on a shared DSP can be the de-
lay master.
See “Sharing a Single Delay Among Multi-
ple Plug-ins” on page 52 for more details on
using a shared delay and designating the
delay master.
If the delay Effect button is not enabled for
any plug-in sharing the same DSP, delay is
turned off.
