If the delay is less than approx. 10 milliseconds, than the effect is called flanging or a flanger effect rather
than chorus. In this case feedback is even more significant because it generates resonances that can be
modulated and is thus yet another source of radical sound effects. If you determine high feedback values,
you can clearly hear how the two sides of the signal are modulated differently - in reverse phase - by the
LFO.
Locate the parameter group CHORUS in the EDIT menu. CHORUS DIR/EFF determines the balance
between the original signal and the processed signal. The parameters RATE and SHAPE control another
LFO that was installed specifically for the chorus LFO. DELAY is used to set the delay time, DEPTH
determines the modulation intensity, and FEEDBACK controls the feedback level.
Please keep in mind that the Chorus section in the Virus is fully stereophonic: Stereo positions as well as
panorama modulations and stereo spread values that you have dialed in elsewhere remain intact in the
effects signal.
The Delay Effect
A delay effect is traditionally used to generated an echo of the input signal. Locate the parameter group
DELAY 
in the EDIT menu. Here you fill find parameters that are virtually identical to the parameters of
the CHORUS group. Do not allow yourself to be confused by the slightly different terminology: The
delay time is set via the parameter entitled TIME (equivalent to DELAY in the CHORUS section); the
other features are FEEDBACK with a dedicated LFO and the familiar parameters RATEDEPTH and
SHAPE
.
Only two functions in the Delay section are different to the Chorus section: For one, it features an
EFFECT SEND 
instead of the balance parameter DIR/EFF. EFFECT SEND is especially significant in
MULTI MODE, where several PARTs with different levels are patched through the same delay effect.
For the other, LENGTH enables you to create substantially longer delay times, for instance to achieve
complete echoes (maximum of 693 ms) that are fully audible. The LFO allows you to modulate the delay
as you would the chorus to achieve similar detuning effects. A stereo effect is achieved via different
modulations of the left and right sides of the signal.
More to Come
We have come to the end of these detailed instructions for novices. We hope we were able to help you
become a bit more familiar with your new synthesizer and gain some confidence in how to handle it. As
we mentioned earlier, this is just an introduction and does not cover all the functions and features of the
Virus, only the basic components and how they affect the sound of the Virus. You should now be able to
come to terms with the in-depth look at the Virus in the following section.
