Lfo 1; The Modulation Targets - Access Virus Rack User Manual

Introduction

LFO 1

Start with the usual basic sound configu-
ration or chose a modified sound to suit
your taste. Locate the RATE encoder in
the LFO 1 section of the control panel.
The VIRUS is equipped with an LED that
indicates the speed of the LFO as well as
its waveshape. Turn the RATE encoder
and check out how the flash of the LED
indicates the change of pace as you
rotate the encoder.
Currently you are unable to hear the
effect of the LFO as its modulation inten-
sity is set to 0 in the sound program. In
order to change this setting, you must
access the five parameters called LFO
AMOUNT button which works with the
modulation destinations Oscillator1,
Oscillator2, PulseWidth1+2,
Resonance1+2 und FilterGain:
í

The modulation targets

refers to the frequency
OSCILLATOR1
of oscillator 1
refers to the frequency
OSCILLATOR2
of oscillator 2
PULSEWIDTH1+2 means that the
pulse widths of both oscillators are
controlled in unison
refers to the reso-
RESONANCE1+2
nances of both filters. Please keep in
mind that although each set of these
parameters is assigned a common
modulation intensity, you can still dial
in different sound-shaping settings
manually. In other words, the audible
result of a joint modulation varies
according to the values you have
determined for the other parameters.
FILTERGAIN This term refers to the
input level of the first filter (and of
course the subsequent saturation
level) - although WITHOUT THE LEVEL
COMPENSATION CONTROLLED VIA
OSC VOL. Here you can actually modu-
late a parameter that is not manually
accessible. The effect of a FiltGain
modulation is a periodic change in the
saturation level which is linked to a
corresponding tremolo (periodic
change in volume). If the signal is not
saturated in any manner, then the only
audible result is a tremolo effect.
