Here’s where you select the algo-
rithm for the DELAY/REVERB sec-
tion.

Let’s take a tour of the different 
algorithms:

OFF Not surprisingly, this setting 
deactivates the DELAY/REVERB sec-
tion.

DELAY Mono echo. Same delay 
time on the left and right sides.

REVERB Room simulation.

REV+FEEDB1 This the Virus' trade-
mark room simulation. Here you 
can use the FEEDBACK control to 
generate pre-delay feedback. The 
feedback effect generates rhyth-
mic repetitions of the REVERB sig-
nal, which are repeated at the 
intervals determined by the 
assigned pre-delay time.

REV+FEEDB2 Room simulation 
with feedback and REV+FEEDB1. 
Here the REVERB signal is audible 
immediately after you hear the dry 
signal rather than after a defined 
amount of pre-delay time has 
elapsed. The rhythmic repetitions 
are independently variable 
depending on the pre-delay time 
and feedback intensity (FEED-
BACK).

DELAY X:Y  Ping-pong delay. 
Although the delay times on the 
left and right sides are different, 
they have a fixed relationship to 
one another. For example, 2:1 
means that the delay time of the 
left side of the delay signal is twice 
as long as that of the right side. 
The absolute delay time refers to 
the longer delay time of the two 
sides. It is determined via DELAY 
TIME or DELAY CLOCK. Feedback is 
also generated using the signal 
with the longer delay time of the 
two.

PATTERN X+Y  The PATTERN delay 
algorithms are also ping-pong 
delays, but here the delay times 
are locked into sync with the mas-
