Oscillator 2 – Front Panel
SHAPE, WAVE SEL/PW
Same as Oscillator 1; see paragraph above.
SEMITONE
Determines the interval between the second oscillator and the first oscillator: Control range +/-48
semitones, assigned in semitone steps.
DETUNE
Detunes the second oscillator relatively to the first. With this parameter, you can dial in everything
from slight deviations in pitch to major fluctuations between the two oscillators.
SYNC
Synchronizes the second oscillator with the first: The SYNC function forces Oscillator 2 to interrupt
its wave cycle and restart it at the same time as Oscillator 1 starts its cycle. The effect of this meas-
ure is that pitch deviations and intervals are no longer audible as such; what you hear are tonal
modifications: Repeated interruption of the Oscillator 2 wave cycle generates new tonal spectra
with a great deal of overtone content. The tone of a given spectrum can be influenced via the SEM-
ITONE knob, among other control features.
FM AMOUNT
Controls the frequency modulation intensity of the second oscillator by the first. Depending on the
selected FM AMOUNT and the interval between the oscillators, the frequency modulation generates
everything from slightly to radically enriched spectra. In the Virus you have the option of combining
the two functions called oscillator synchronization (SYNC) and frequency modulation (FM AMOUNT)
to generate new harmonic spectra. The characteristics of the frequency modulation can be modi-
fied with the FM Mode parameter (in the OSCILLATOR EDIT menu). You may also select an external
audio signal and have Oscillator 2 modulate its frequency.
