MODULATOR PARAMETER
Modulator Parameters
The MOD menu contains all the parameters for the LFOs (Low Frequency Oscillators) and the Modulation
Matrix. You can use a wide variety of modulators to apply dynamic changes to the sound, such as vibrato or
tremolo effects, automated sweeps etc.
Traditionally, LFOs (low frequency oscillators) are used for cyclic modulation e.g. vibrato, tremolo etc.. Alter-
natively, two of the three LFOs in the Virus can serve as simple envelopes, 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 des-
tination to be selected.
LFO 1
Cloc • k
Value Meaning
Off LFO1 is not synchronized.
1/64 ... 16/1 LFO1 rate is synchronized to the Clock, expressed as a fraction of one bar in 4/4 time.
Ra • te
0 to 127: The speed of LFO1 when not synchronized (see “Clock” above).
Modulation destination “LFO1 Rate“.
Shap • e
Sine, Triangle, Sawtooth, Square, S&H, S&G, Waves 3 to 64: Species the LFO waveform.
Co • ntour
-64 to +63: Continuous control over LFO waveform.
