or inharmonic sounds (which very well could be exactly what you want...).
The amplitude of an oscillator depends on the Level setting of the oscillator in the shell and
on its envelope, which is shown in its display and can be adjusted from there. It can also
be modied by note velocity and note pitch with the Level<Vel and Level<Key parameters
available in the lower portion of each oscillator's display.
The phase of each oscillator can be adjusted using the Phase control in its display.
As explained earlier oscillators can modulate each other when set up to do so with the
global display's algorithms. When an oscillator is modulating another oscillator, two main
properties dene the result: the amplitude of the modulating oscillator and the frequency
ratio between both oscillators. Note that Oscillator D can modulate itself via the Feedback
parameter available in its display.
20.3.3 LFO Section
Operator's LFO
Parameters.
The LFO in Operator can practically be thought of as a fth oscillator. It runs at an audio rate,
and it modulates the frequency of the other oscillators. It is possible to switch modulation by
the LFO on or off for each individual oscillator (and the lter) using the Destination buttons
in the LFO's display. The LFO can also be turned off if it is unused.
