81 SOUND PARAMETERS REFERENCE
MODULATORS
Traditionally, LFOs (low frequency oscillators) are used for
cyclic modulation e.g. vibrato, tremolo etc.. Alternatively, two of
the three LFOs in the Virus can serve as simple envelopes (see
“Envelope Mode” on page 83), so the label “Modulators” seems
more appropriate than “LFOs” for this section.
Note that each LFO in the Virus has a different set of preset
destinations, and that LFO3 allows just one destination to be
selected.
EDIT
Opens the LFO menu corresponding to the selected LFO (see
SELECT below). Selecting a different LFO after opening this
menu will jump directly to the menu for the newly selected LFO.
ENV MODE
Toggles the Envelope Mode parameter on and off (see “Enve-
lope Mode” on page 83).
SHAPE
Quick selection of Sine, Triangle, Sawtooth, Square or WAVE –
the waveform specified in the Edit menu (see “Shape” on
page 82).
RATE
Controls the speed of the currently selected LFO (see “Clock”
on page 82 and “Rate” on page 82).
LFO CONTOUR
Via SHIFT + RATE. Continuous control over LFO waveform (see
“Contour” on page 83).
