Tutorial 6: Virus Indigo Effects
Virus Indigo provides a number of effects, such 
as phasing, chorus, reverb, and delay, that you 
can use to enhance patches. 
The Chorus Effect
Adding chorusing to a patch is a simple way to 
enliven its sound. Memory Location 1 demon-
strates this effect on an otherwise static patch.
To hear the Chorus effect:
1 Open the “Tutorial 6” session.
2 Record enable the Instrument track so that 
you can play Virus Indigo using a MIDI key-
board controller.
3 At the upper left of the Virus Indigo plug-in, 
click FX-1 to show the effects page.
4 Click memory location 1, “Chorus” and press 
the Spacebar to begin playback.
When playback stops, experiment with the var-
ious Chorus controls while playing the patch 
with your MIDI keyboard controller.
Using the Arpeggiator
Arpeggiators are typically used to add a highly-
sequenced “techno” feel to music. 
If you play a note or a musical chord, the Arpeg-
giator will play the individual notes in succes-
sion, across a selected octave range, at a selected 
tempo.
